Robinson Meyer:
[1:25] Hi, I’m Robinson Meyer, the founding executive editor of Heatmap News. It is Friday, February 20. This morning, the Supreme Court threw out President Trump’s most aggressive tariffs, ruling that the International Emergency Economic Powers Act of 1977, usually called IEEPA, does not allow the president to impose broad, indiscriminate tariffs on other countries. Had Congress intended to convey the distinct and extraordinary power to impose tariffs, it would have done so expressly, Chief Justice John Roberts wrote. It was a bit of a stitched together decision. Clarence Thomas, Samuel Alito, and Brett Kavanaugh dissented, while Neil Gorsuch, Amy Coney Barrett, and the chief justice ruled with the liberals, although the liberals only concurred with some of the decision. But it takes away a major tool of economic and diplomatic policy making for President Trump.
Robinson Meyer:
[2:12] There were really two sets of tariffs affected by this decision. One was a set of so-called reciprocal tariffs imposed on most countries in the world and set between 10% and 50%. And the second were what Trump called the fentanyl tariffs on China, Mexico, and Canada. Now, the president basically immediately followed up this ruling by saying he would impose a 10% universal tariff on all countries. We’re still trying to understand how exactly he would do that and what it would mean, and we’ll talk about it on the show. But we wanted to have a conversation on an emergency basis here on an emergency shift key episode about what this means for clean energy and what this could also mean for Trump’s industrial policy, such as it is going forward.
Robinson Meyer:
[2:53] Joining us today is Jonas Nahm. He’s an associate professor at the John Hopkins School of Advanced International Studies in Washington, D.C., and he was recently senior economist for industrial strategy at the White House Council of Economic Advisors. He studies industrial policy, supply chains and trade, and he’s the author of Collaborative Advantage: Forging Green Industries in the New Global Economy. Jonas, welcome to Shift Key.
Jonas Nahm:
[3:18] Thank you for having me. I’m finally on.
Robinson Meyer:
[3:20] You’re finally here. We finally got you. So I think let’s just start here. What do you make of the ruling today and then the president’s kind of successive 10% tariff announcement?
Jonas Nahm:
[3:33] I don’t think this was surprising, right? We had, during the hearings, kind of gotten this impression that the judges were somewhat skeptical, at least, of the ability of the president to use IEEPA to justify these tariffs. And so I think the surprise was really that it took so long. There were lots of rumors floating around for the past couple of months that this would come out any time. And so it finally came, but it sort of came in the form that everyone expected. And the conclusion today was that this is not a tariff statute and that there are other authorities for the president to use to do these things, but this isn’t one of them.
Robinson Meyer:
[4:09] I feel like the most interesting thing, I kind of hinted at this in the intro, was that Brett Kavanaugh, ruled, first of all, that the tariffs were legal, which is kind of crazy, but also that he was like, this is not the proper use of the major questions doctrine, a doctrine he invented to constrain executive authority. But that’s neither here nor there.
Jonas Nahm:
[4:28] Which the liberal justices also didn’t sign on to, right? So it was sort of three people saying this is major questions, and then three people saying this is just, you know, illegal.
Robinson Meyer:
[4:39] Yes. And I think maybe crucially for this audience, Justice Gorsuch cited disapprovingly the Trump administration’s argument that a future president could use IEEPA, the statute in question here, to impose tariffs on fossil fuels or internal combustion engines because it considers climate change to be a national security threat. That was like an argument made by President Trump’s team on behalf of the tariffs to convey their belief that IEEPA had this huge economic policymaking power within it. And Justice Gorsuch was like, no, no, no, it doesn’t let you do that. And it also doesn’t let you impose these tariffs on all these other countries. OK, so I will say I have basically spent every moment up until now not learning about the other tariff authorities. They all are like known by a different number. And it always seemed like people were mentioning a new one. So can you walk us through just like with IEEPA out of the way, what are the other things? Authorities or powers under the law that have been used to impose tariffs on the past or that are seen as kind of being the other powers the president could invoke here if he wanted to keep slapping tariffs on major trading partners?
Jonas Nahm:
[6:00] So one of the big advantages of the IEEPA path for the administration was that it didn’t really involve a lot of procedure. And they had a lot of discretion. Now, no more. But at the time, thinking that they could do this, they had a lot of discretion about how to do this, who to apply this to, which products to exempt, and how to change it very quickly. And so it was basically fairly unconstrained. And so the other authorities all come with more process. And many of them are already in place with more process. So I think one thing to maybe start with is that the IEEPA tariffs are only one part of this tariff stack, and that different products have other tariffs applied to them already. Some of them stack on top of one another, some of them don’t, but there are many kind of authorities in this space that are being used at the same time.
Jonas Nahm:
[6:51] The president came out today and said they’re going to impose 10% universal tariffs under the Section 122, which is from the Trade Act of 1974, which is really to address kind of a large and serious deficit, it can be done very immediately, but it’s capped at 15%. They said they’re going to use 10. The problem for them is that it expires in 150 days unless Congress extends it. So it can sort of stop the revenue loss from taking away the reciprocal and the fentanyl tariffs. It can buy time for permanent fixes, but itself is not really a permanent solution unless there’s congressional buy-in in 150 days, which seems somewhat unlikely. So that’s what they’ve already decided they’re going to use sort of as the bridge to get to these other authorities.
Jonas Nahm:
[7:40] There’s another tariff authority called Section 232, which is about national security related issues. And so there you need to have an investigation and then you can impose these tariffs. We have lots of these investigations ongoing. Some of them are already completed, but pharmaceuticals, robotics, chips, I mean, there’s a bunch of them that are out there. And so what they don’t like about this is that you have to have this investigation so it’s not immediate. it. And so it requires a little bit of process.
Robinson Meyer:
[8:11] Like a Commerce Department investigation, right? This is like a, it’s like a known process where they...
Jonas Nahm:
[8:18] Yeah, and there needs to be a hearing and yes, all of those things. So that’s 232. And then you have Section 301, which is about unfair trade practices. That also requires an investigation and a public hearing, kind of a common period where industry can weigh in. And so you could use that to recreate these tariffs on a country by country basis, the Section 232 tears are mostly at the sectoral level. So the investigations are about sectors that have national security implications, although that has also been stretched widely by this administration. We’ve applied them to kitchen cabinets in this past year, so I don’t immediately follow the national security implications there. But, you know, there is some leeway there in how this is laid out. Section 301 is about unfair trade practices. And then there are the tariffs that were used, you know, almost 100 years ago after the depression, which is Section 338. That gets thrown around a lot. I think it has a lot less procedural constraints attached to it than these other ones. But it’s also untested in modern courts. And this would require the administration to prove that there’s discrimination against U.S. exports. And you could imagine a lot of litigation around how to define discrimination. And so these are sort of the broad authorities that exist and that the administration
Jonas Nahm:
[9:38] has signaled they will rely on. I think mostly the first three.
Robinson Meyer:
[9:41] It does seem like, I think one thing hearing this list is that there’s five other tariff authorities he could use. And while some of them have restrictions on time or duration or tariff rate, there’s actually still a good amount of like untested tariff authority out there in the law and if the president and his administration were like quite devoted they would be able to go out there and, figure out the limits of 338 or figure out the limits of of 301?
Jonas Nahm:
[10:17] Yeah, I mean, I think one thing to also think about is what is the purpose of these tariffs? Right. And so I think the justifications from the administration have been varied and changed over time. But, you know, they’ve taken in a significant amount of revenue, some 30 billion dollars a month from these tariffs. This was about four times as much as in the Biden administration. And so there is some money coming in from this. And so 122, the 10% immediately, would bring back some of that revenue that is otherwise lost. One question is what’s going to happen to refunds from the IEEPA tariffs? Are they going to have to pay this back? It seems like that’s also kind of a court battle that needs to be fought out. And the Supreme Court didn’t weigh in on that. But, you know, the estimates show that if you brought the 122 in at 10%, you would actually recoup a lot of the money that you would otherwise lose and the effective tariff rate in the U.S. Would go back from 10% to about 15%, roughly to where it was before the Supreme Court ruled on it.
Robinson Meyer:
[11:18] Has the effect of tariffs from the Trump administration been larger or smaller than what you thought it would be? Not necessarily in the immediate aftermath of “liberation day”, because he announced these giant tariffs and then kind of walked some of them back. But like the tariff rate has gone up a lot in the past year. Has the effect of that on the economy been more or less than you expected?
Jonas Nahm:
[11:43] I think that the industrial policy justification that they have also used is a completely different bucket. Right. So you can use this for revenue and then you can just sort of tax different sectors at different times as long as the sum overall is what you want it to be. From an industrial policy perspective, all of this uncertainty is not very helpful because if you’re thinking about companies making major investment decisions and you have this IEEPA Supreme Court case sort of hanging over the situation for the past year, now we don’t know exactly what they’re going to replace it with, but you’re making a $10 billion decision to build a new manufacturing plant. You may want to sit that out until you know what exactly the environment is and also what the environment is for the components that you need to import, right? So a lot of U.S. imports actually go into domestic manufacturing. And so it’s not just the product that we’re trying to kind of compete with by making it domestically, but also the inputs that we need to make that product here that are being affected.
Jonas Nahm:
[12:38] And so for those kinds of supply chain rewiring industrial policy decisions, you probably want a lot more certainty than we’ve had. And so the Supreme Court ruling against the IEEPA tariff justification is certainly more certainty in all of this. So we’ve now taken that off the list. But we are not clear what the new environment will look like and how long it’s going to stick around. And so from sort of an industrial policy perspective, that’s not really what you want. Ideally, what you would have is very predictable tariffs that give companies time to become competitive without the competition from abroad, and then also a very credible commitment to taking these tariffs away at some point so that the companies have an incentive to become competitive behind the tariff wall and then compete on their own. That’s sort of the ideal case. And we’re somewhat far from the ideal case. Given the uncertainty, given the lack of clarity on whether these things are going to stick around or not, or might be extended forever, and sort of the politics in the U.S. that make it much harder to take tariffs away than to impose them.
Robinson Meyer:
[15:26] I have heard from Democrats and like Democratic economic policymaker making staff, let’s say, that they really did believe that when Trump announced all these tariffs, that what people said it was going to crash the economy. And the fact that it like hasn’t necessarily crashed the economy has made some of them go, huh, well, maybe tariffs aren’t as bad as we kind of were told they were. And we should consider them as part of a broader economic playbook. Looking over the past year, have you been surprised by how resilient the U.S. economy has been despite all these new trade restrictions that didn’t exist two years ago?
Jonas Nahm:
[16:04] I think the answer to that question really depends on what you’re looking at specifically, right? So if this was supposed to be a manufacturing reshoring tool, in some ways it’s too early to tell whether it’ll work. We’ve seen this during the Biden administration. The Inflation Reduction Act came out. And by the time the election rolled around, a lot of these plants were still under construction. So in some ways, the theory was still untested on whether
Jonas Nahm:
[16:28] that would have changed people’s voting behavior, because we didn’t have enough time. And so in the same way, we don’t have enough time now. And we’ve seen manufacturing job losses over the last year, things have picked up a little bit recently, and sort of capacity utilization is up this month, or last month, rather in the U.S.. But I think that is from using existing plants more rather than building new ones in response to the tariffs. And of course, there are big announcements that have been made where companies that were going to build a plant in Canada are now building it in the U.S.. And some changes in decision-making have occurred as a result of it. But I think to really judge this as a sort of reassuring manufacturing industrial policy, it’s just too early. And I think the uncertainty really also then prolongs the period that it would take for companies to really do this. I mean, you’d want to think about that decision quite carefully. And while a lot of this stuff is still ongoing, I think companies have just avoided making big decisions.
Robinson Meyer:
[17:27] It’s also unclear to me how much of American trade tariffs actually did fall on in terms of specific bilateral relationships. So to be specific, like we talk about these fentanyl tariffs, which is the president’s name for what he said were 25% tariffs on Canada and Mexico and 10% tariffs on China and 10% tariffs on Canadian energy exports. And what, Those are big numbers, but what wound up happening in the immediate aftermath of his initial decision was that trade previously authorized under USMCA, the successor to NAFTA, was exempted or wasn’t fully subject to that tariff. And what that meant is that basically, for instance, no Canadian oil exports have ever been subject to this 10% tariff. It’s totally trade as normal between the two countries, at least on an energy basis, and yet. But notionally on the books, there is a threat of a much higher tariff, I suppose, if the president were to change his mind or in the future.
Jonas Nahm:
[18:31] I think you raise a really good point also because the effective tariff rate was around 15 or 16% or so, much lower than some of these headline numbers that were being thrown around. And that’s because we’ve exempted a lot of stuff, right? So coffee prices went up and we exempted Brazilian coffee imports. And we’ve taken other key industries out of this calculation. And USMCA-compliant goods were exempted from the fentanyl tariffs on Canada and Mexico. And so overall, the sort of number of products that are being impacted are much smaller than everything. And one of the interesting questions I think now is, for instance, in the Section 122 10% game that they’re trying to play, the process for exempting and excluding certain products works differently. And so if this really becomes a universal 10%, it would actually affect a lot of things that currently aren’t being tariffed by the reciprocal tariffs. And they don’t have a lot of time. So maybe that also plays into it where they don’t have the capacity to really plan it out strategically. And so if we’re now then moving to a world where a lot of critical inputs into domestic manufacturing are being tariffed at 10% that were previously exempt, that might have some negative consequences for the manufacturers that are trying to survive and all of this uncertainty.
Robinson Meyer:
[19:49] I guess that also removes like a huge opportunity for corruption, because one thing that would happen is the president would take not only like coffee out of the tariff. One thing that would happen is the president wouldn’t only remove tariffs on product categories like coffee, but he would just remove them from companies or put them back on other companies. And it seemed like this huge black box of potential corruption that there just wasn’t a lot of visibility into.
Robinson Meyer:
[20:17] Let’s talk about the sectors that we follow here. So what does this Supreme Court case mean, if anything, for electric vehicles?
Jonas Nahm:
[20:28] Maybe before we jump into this, just to remind everyone, so we’ve taken away one layer of this kind of cake of tariffs that we’ve built here over time. There’s Section 301, there’s Section 232s, there’s anti-dumping and countervailing duties. Sometimes there’s safeguards, Section 201. And so all of those things can apply to the same product. And so we’re sort of taking one piece out of that stack, but it means the others are still there.
Robinson Meyer:
[20:52] And crucially, this is not like a supermarket sheet cake with two layers or even a pound cake like you might.
Jonas Nahm:
[20:59] Make at home. No, it’s a fancy cake.
Robinson Meyer:
[21:00] It’s a Russian honey cake with 12 or 13 layers stacked upon each other of delectable trade-fine goodness.
Jonas Nahm:
[21:09] That’s exactly right. And so if we think about EVs, for instance, the European companies actually aren’t being tariffed under IEEPA. They’re tariffed under Section 232 for autos and parts, which is a totally different legal foundation. And so they are not benefiting from IEEPA going away. They might now get hit with 122s on top of what they were paying previously if that isn’t designed carefully. And so there’s a lot of open questions about what that actually looks like in practice, but it’s certainly not helping them. On the China side, which is probably our bigger concern, is that electric vehicles are already in the Section 301 penalty box and they get 100% on EVs and there’s tariffs on batteries under 301. So IEEPA was there with 10% for these products, but it wasn’t really the significant piece. And so I think there it doesn’t fundamentally change the landscape. But the problem, I think, is more that we have uncertainty and there’s this constant turmoil over what it’s going to be. And we have four meetings between Xi and Trump lined up for the year and he’s supposed to go there at the end of March and lots of uncertainty sort of in the policy space that IEEPA kind of feeds into, but wasn’t really that critical, I think.
Jonas Nahm:
[22:23] And on China specifically, the U.S.TR, the Office of the Trade Representative, launched in the fall a Section 301 investigation on China saying that they hadn’t adhered to the requirements of the phase one trade deal from the first Trump administration. They held the public hearings. They probably have a report ready to go. So they could reimpose also kind of on a national level 301 tariffs on China based on this finding, which could more than offset the loss of the Aiba tariffs.
Robinson Meyer:
[22:53] Okay, next sector. So what does this mean for solar? Because one interesting subplot here that my colleague Matt Zeitlin was talking about earlier today is that after “liberation day”, Wall Street became very convinced that First Solar, this U.S. solar manufacturing firm, was going to be the huge beneficiary of this new Trumpian tariff regime. And it really has not been at all. It’s like, it turned out that a lot of its inputs had new tariffs on them, that it really didn’t affect its business very much. But there are a lot of tariffs on solar. Are they that go back all the way to the Biden administration or the first Trump administration? Were those issued under IEEPA? And what is their current status?
Jonas Nahm:
[23:36] Solar was affected by the IEEPA layer in China, for instance, but there are other tariffs in place that are much more significant. And then on China and also Southeast Asian suppliers, there are anti-dumping and countervailing duties in place that are issued to specific companies. And so the rate kind of depends on which company, but some of them are over 200%. So there you might have a loophole that like a new supplier springs up that isn’t yet affected by this countervailing duty regime. And so they might benefit. But I think there are two, the IEEPA story is only one layer. We had Section 201 safeguards on solar that I think were expiring in February this year. So that layer was ending and now IEEPA is ending. But Section 301 on China and the ADECVDs remain in place and I think are going
Jonas Nahm:
[24:26] to make it unlikely that we see the sudden onslaught of Chinese supply.
Robinson Meyer:
[24:30] Are there any other kind of sectors to talk about here, you know, really affected by this or, I don’t know, data center inputs?
Jonas Nahm:
[24:41] Wind, I think, was exposed to the IEEPA layer to some degree, but I think the other question is more broadly, what are we doing with the domestic wind industry? There’s also a 232 national security investigation that is ongoing on wind that they could switch to as a justification, both on wind turbines and turbine parts. And so there, I think we might see some sort of temporary IEEPA relief, especially for inputs like metals and so on that are now coming in, perhaps at different prices. I don’t know if that can really help the wind industry overcome the broader headwinds that they’re facing with this administration. But, you know, if there is a real positive impact, I would expect them to very quickly switch to the 232 justification to make up for it. I think on data centers, it’s interesting.
Jonas Nahm:
[25:29] Data centers import a huge amount of equipment, right? So servers, networking, equipment, power distribution, cooling, switch, there’s all this stuff that goes into a data center. And if IEEPA went away and nothing replaces it, that might actually be a meaningful relief for a lot of that stack. But now under this 10% 122 surcharge, it’s coming back. And if some of these exemptions that we had in place for some of these components in order to support domestic data center build out are not included, and we have to see how they actually implement this, this could be quite negative. But to me, this is really a story at this point of thinking about this way more as a revenue source than a strategic industrial policy that’s trying to reshore certain sectors. And the more we change it up and switch from one authority to another, the more it becomes a revenue story because the actual economic impact in terms of reshoring is going to be less and less.
Robinson Meyer:
[26:22] So one thing I’m taking from this conversation is that while clean energy and energy inputs might get a tiny bit of relief, largely they were already subject to this existing stack of pre-existing tariff authorities under other laws. And so they might benefit from like some economic tailwinds from this, but it’s not like Chinese or Southeast Asian solar panels are going to suddenly
Robinson Meyer:
[26:50] be available in the United States at cost. Stepping back then, what is your read of how this ruling fits into the Trump administration’s trade policy, and I think broadly, America’s attempt to formulate some kind of industrial policy that now started with the first Trump administration, was continued and changed by the Biden administration, and now soldiers on under the second Trump administration.
Jonas Nahm:
[27:19] If I think about this broadly in terms of sort of economic policymaking, the tariffs are one tool you can use to shape the nature and structure and composition of the domestic economy. In many ways, what I think is much more important is what do you do behind the tariff wall to really help companies build competitive manufacturing capacity, for instance, right? And the tariffs themselves are not really enough to do much there. And a lot of the incentives and sort of support that, for instance, the Inflation Reduction Act included, that have been taken away or it’s shortened significantly. And so we’re doing kind of less on the domestic economy and we’re doing more at the border. But I think ideally you would do
Jonas Nahm:
[28:08] Much more certainty at the border, and then combine it with a domestic strategy. And I think we’re seeing some of this now happen kind of in the critical mineral space, you know, Vault, Forge, all these kinds of new initiatives that are being pushed out by the administration to look at the demand side, and kind of create more stable markets for these technologies, for instance. So slow beginnings of kind of the supply side and demand side match in pairing different industrial policy tools. But in some ways, I think this tariff game has been a huge distraction from the actual work that we need to do on vocational training, on financing for manufacturing, on creating stable demand for these technologies that we want to make domestically so that companies can get financing and invest. And so looking at trade policy in that kind of broader picture, it looks more like a revenue policy than an industrial policy because it’s not really coordinated with these other elements.
Robinson Meyer:
[29:05] I think we’ll have to leave it there. Jonas Nahm, thank you so much.

Plus news on cloud seeding, fission for fusion, and more of the week’s biggest money moves.
From beaming solar power down from space to shooting storm clouds full of particles to make it rain, this week featured progress across a range of seemingly sci-fi technologies that have actually been researched — and in some cases deployed — for decades. There were, however, few actual funding announcements to speak of, as earlier-stage climate tech venture funds continue to confront a tough fundraising environment.
First up, I explore Meta’s bet on space-based solar as a way to squeeze more output from existing solar arrays to power data centers. Then there’s the fusion startup Zap Energy, which is shifting its near-term attention toward the more established fission sector. Meanwhile, a weather modification company says it’s found a way to quantify the impact of cloud seeding — a space-age sounding practice that’s actually been in use for roughly 80 years. And amidst a string of disappointments for alternate battery chemistries, this week brings multiple wins for the sodium-ion battery sector.
One might presume that terrestrial solar paired with batteries would prove perfectly adequate for securing 24/7 clean energy moving forward, as global prices for panels and battery packs continue to fall. But the startup Overview Energy, which uses lasers to beam solar power from space directly onto existing solar arrays, thinks its space-based solar energy systems will prove valuable for powering large loads like data centers through the night. Now Meta is backing that premise, signing a first-of-its-kind agreement with Overview this week that secures early access for up to a gigawatt of capacity from the startup’s system.
Initial orbital demonstrations are slated for 2028, with commercial power delivery targeted for 2030. It’s an ambitious timeline, and certainly not the first effort to commercialize space-based solar, though prior analyses have generally concluded that while the physics check out, the economics and logistics don’t. Overview Energy thinks its found the core unlocks though: “geographic untethering,” which allows it to direct its beam to ground-based solar arrays anywhere in the world based on demand, and high-efficiency lasers capable of converting near-infrared light into electricity much more efficiently than pure sunlight.
The startup is targeting between $60 and $100 per megawatt-hour by 2035, at which point the goal is to be putting gigawatts of space solar on the grid. “It’s 5 o’clock somewhere,” Marc Berte, founder and CEO of Overview Energy, told me when I interviewed him last December. “You’re profitable at $100 bucks a megawatt-hour somewhere, instantaneously, all the time.”
Launch costs have also fallen sharply since the last serious wave of space-solar research, and Overview has already booked a 2028 launch with SpaceX. Solar power beamed from space also sidesteps two earthly constraints — land use and protracted grid interconnection timelines. So while this seemingly sci-fi vision remains unproven, it might be significantly more plausible than it once appeared. And Meta’s certainly not alone in taking that bet — Overview has already raised a $20 million seed round led by Lowercarbon Capital, Prime Movers Lab, and Engine Ventures.
Fusion startups are increasingly looking to nearer-term revenue opportunities as they work toward commercializing the Holy Grail of energy generation. Industry leader Commonwealth Fusion Systems is selling its high-temperature superconducting magnets to other developers, while other companies including Shine Technologies are generating income by producing nuclear isotopes for medical imaging. Now one startup, Zap Energy, is pushing that playbook a step further, announcing this week that it plans to develop fission reactors before putting its first fusion electrons on the grid.
Specifically, the startup is now attempting to develop small modular reactors — hardly a novel idea, as companies like Oklo, Kairos, and TerraPower have already secured significant public and private funding and struck major data center deals. Zap, however, thinks it can catch up to these new competitors in part by leveraging design commonalities between fission and fusion systems, including the use of liquid metals, engineered neutron environments, and high-power-density systems. “Fission and fusion are two expressions of the same underlying physics," Zap’s co-founder Benj Conwayby said in the press release. "This isn’t a pivot — by integrating them into a single platform, we can move faster, reduce risk, and build a more enduring company."
As the company outlines on its website, pursuing both pathways could eventually manifest in the development of a hybrid fusion-fission system, while also giving Zap practical experience interfacing with regulators and securing approvals. As The New York Times reports, the company is targeting an early 2030s timeline for its fission reactors, although Zap has yet to specify a timeline for fusion commercialization. Like so many of its peers, the company is eyeing data centers as a promising initial market, though bringing its first units online will likely require a significant influx of additional capital.
For all the concern surrounding geoengineering fixes for climate change such as solar radiation management, there’s one form of weather modification that’s been in use since the 1940s — cloud seeding. This practice typically involves flying planes into the center of storms and releasing flares that disperse a chemical called silver iodide into the clouds. This causes the water droplets within the clouds to freeze, increasing the amount of precipitation that falls as either rain or snow.
Alarming as it may sound for the uninitiated, there’s no evidence that silver iodide causes harm at current usage levels. But what has been far more difficult to pin down is efficacy — specifically, how much additional precipitation cloud seeding actually creates. That’s where the startup Rainmaker comes in. The company, which deploys unmanned drones to inject the silver iodide, says that its advanced radar and satellite systems indicate that its operations generated over 143 million gallons of additional freshwater in Oregon and Utah this year — roughly equivalent to the annual water usage of about 1,750 U.S. households. The findings have not yet been peer reviewed, but if accurate, they would make Rainmaker the first private company to quantify the impact of its cloud seeding operations.
Cloud seeding is already a well-oiled commercial business, with dozens of states, utility companies and ski resorts alike using it to increase snowfall in the drought-stricken American West and worldwide — China in particular spends tens of millions of dollars per year on the technology. Rainmaker has a particular aspiration: to help restore Utah’s Great Salt Lake, which has been shrinking since the 1980s amid rising water demand and increased evaporation driven by warmer temperatures.
In a press release, the company’s 26-year-old founder and CEO Augustus Doricko said, “With the newfound capability to measure our yields and quantify our results, Rainmaker will go forward and continue our mission to refill the Great Salt Lake, end drought in the American West and deliver water abundance wherever it is needed most around the world."
Sodium-ion batteries have long been touted as an enticing alternative — or at least complement — to lithium-ion systems for energy storage. They don’t rely on scarce and costly critical minerals like lithium, nickel, or cobalt, and have the potential to be far less flammable. The relatively nascent market also offers an opening for the U.S. to gain a foothold in this segment of the battery supply chain. But especially domestically, the industry has struggled to gain traction. Two sodium-ion startups, Natron and Bedrock Materials, both closed up shop last year as prices for lithium-iron-phosphate batteries cratered, eroding sodium-ion’s cost advantage, while the cost of manufacturing batteries in the U.S. constrained their ability to scale.
But one notable bright spot is the startup Alsym Energy, which announced this week that it has signed a letter-of-intent with long-duration energy storage company ESS Inc. for 8.5 gigawatt-hours of sodium-ion cells and modules, marking ESS’s expansion into the short and medium-duration storage market. Alsym’s CEO, Mukesh Chatter, told me this represents the largest deal for sodium-ion batteries in the U.S. to date — although it’s not yet a binding contract. Notably, it came just a day after the world’s largest-ever order for these batteries, as CATL disclosed a 60 gigawatt-hour sodium-ion agreement with energy storage integrator HyperStrong. Taken together, these partnerships suggest the sector is finally picking up durable traction both domestically and abroad.
ESS, however, is facing its own operational headwinds, nearly shuttering its Oregon manufacturing plant last year before securing an unexpected cash infusion and pivoting to a new, longer-duration storage product. Chatter remains exuberant about Alsym’s deal with the storage provider, however, telling me it represents a major proof point in terms of broader industry acceptance and an acknowledgement that “the benefits [sodium-ion] brings to the table are significant enough to overcome any stickiness” and hesitation around adopting new battery chemistries.
Chatter said that interest is now pouring in from all sides, citing inquiries from lithium-ion battery manufacturers, utilities, and defense companies and highlighting use cases ranging from data centers to apartment buildings and mining operations as likely early deployment targets.
A handful of startups are promising better, cheaper, safer water purification tech.
The need for desalination has long been clear in water-scarce regions of the planet. But with roughly a quarter of the global population now facing extreme water stress and drought conditions only projected to intensify, the technology is becoming an increasingly necessary tool for survival in a wider array of geographies.
Typically, scaling up desalination infrastructure has meant building costly, energy-intensive coastal plants that rely on a process called reverse osmosis, which involves pushing seawater through semi-permeable membranes that block salt and other contaminants, leaving only fresh water behind. Now, however, a number of startups are attempting to rework that model, with solutions that range from subsea facilities to portable desalination devices for individuals and families.
They could find potential customers across the globe. Many countries in the Middle East — including Saudi Arabia, Israel, Bahrain, Kuwait, and Qatar — rely on desalination for the bulk of their municipal water. Meanwhile, drought-prone regions from Australia to the Caribbean and California have also turned to the technology to shore up supply. But as the Iran war has underscored, this vital infrastructure is increasingly being treated as a military target, exposing a significant vulnerability in a resource relied upon by hundreds of millions.
One more resilient alternative is to move the plants underwater — making them more difficult to target while also harnessing subsurface pressure to do some of the energy-intensive work of desalination.
“I came up with the idea of using natural pressure to run the process,” Robert Bergstrom, a veteran of the water industry and CEO of the desalination startup OceanWell, told me. That meant “putting the membranes in a place where it’s already 800 pounds [of pressure] per square inch” — e.g. inside pods on the ocean floor, each capable of producing 1 million gallons of freshwater daily. By using the natural pressure of the ocean to drive the reverse osmosis process, this approach cuts energy use by about 40%, he said, thus slashing the system’s largest operating cost: electricity.
OceanWell’s design maintains a lower internal pressure within each pod than the surrounding environment, causing seawater to flow passively inside and push through membranes — just like on land, but without the high-pressure pumps. Compact pumps inside the pods then push the freshwater up a pipeline to the shore, while the resulting brine dissipates in the deep ocean.
The method also helps solve another problem with conventional desalination: environmental impact. Today’s facilities typically produce a more concentrated brine that they discharge at the ocean’s surface, which is more disruptive to marine ecosystems. The plants also frequently cause damage to organisms large and small by either trapping them against water intake screens or pulling them into the plant itself. That’s been a big sticking point when it comes to permitting these facilities, especially in California where the startup is based. OceanWell’s system, Bergstrom said, is able to filter out larger organisms while allowing microscopic ones to pass through the pods and return to the ocean.
The company began a trial last year in partnership with Las Virgenes Municipal Water District in southern California, testing its system in a freshwater reservoir full of marine life to verify its safety. Next it will test its pods in the ocean before undertaking a pilot in a to-be-determined location — California, Hawaii, and Nice in southern France are all contenders. If all goes according to plan, OceanWell will follow that up with a full-fledged commercial system targeted for 2030.
But it’s not the only startup pursuing underwater desalination — or even the one with the most aggressive timeline. Two years ago, Norwegian startup Flocean spun out of the subsea pump specialist FSubsea with a similar technical approach and a plan to deploy its first commercial system off Norway’s western coast this year. Flocean has already logged over a year of testing in the deep ocean, a stage OceanWell has yet to reach.
OceanWell thinks it can differentiate itself by meeting the unusually stringent permitting required in California. “If we can get it done in California, then the rest of the world will follow,” Bergstrom told me, meaning more resilient, more energy-efficient freshwater infrastructure for all. But it’s a high bar. The last major effort to build a desalination facility in the state led to a long-running fight that ended in 2022 with a rejection. Over 100 groups opposed the facility proposed for Orange County, citing risks to marine life, as well as high energy requirements and costs, with many arguing that alternatives — such as conservation and wastewater treatment — would be more superior options.
Megan Mauter, an associate professor of civil engineering at Stanford, thinks the groups may have a point, especially when it comes to overall system costs. The high capex of desalination can be hard to justify in California, she told me, since the state doesn’t need it 100% of the time, only in bad drought years. For example, just a few weeks ago, The Wall Street Journal reported that San Diego County’s desalination plant, by far the largest in California, now has a surplus of desalinated water that it’s looking to sell to drought-ridden Western states such as Nevada and Arizona.
And while desalination startups purport to cut overall system costs, she has her doubts about that. “The energy savings that they’re going to get are offset by some pretty high increased costs of the other elements of their plant designs,” Mauter told me. “In a subsea system, you’ve got these unproven and not mass-manufactured skids. You’ve got subsea installation, and then mooring it, and putting in pipelines that you’ve got to maintain all the way to land. You’ve got to convey water back to shore, which takes energy, and you are going to have significantly higher maintenance burdens in an open ocean environment.”
Despite her reservations, she certainly sees the appeal of non-traditional water sources, “even at costs that would have been totally infeasible a decade ago.” Municipal planners are staring down a future of worsening drought at the same time that states in the Colorado River basin remain locked in contentious negotiations over water rights, debating how to allocate cuts as river flows have declined nearly 20% since 2000. California’s narrow continental shelf also makes it an ideal environment for subsea desalination, as having deep water close to shore allows the system to harness pressure depths while minimizing the length of the pipeline needed to transport freshwater to land. Norway is also favored in this way.
“I don’t know whether the cost gaps can be solved, but I bet that the technology gaps could be solved,” Mauter told me.
Ultimately, she thinks the binding constraint is likely to be regulatory rather than technical. “Permitting is going to be a nightmare unless something fundamentally changes,” she said. Bergstrom told me that OceanWell is currently working with the California State Water Resources Control Board to revise its rules that govern desalination facilities in order to account for new technologies, though how long that process will take is anyone’s guess.
There’s one idea emerging in this ecosystem that largely sidesteps the regulatory constraints that control our land and seas. The startup Vital Lyfe has developed a portable desalination unit roughly the size of a small cooler that allows individuals and households to produce freshwater on demand with reverse osmosis — effectively decentralizing the desalination industry in the same way that the startup’s founders, former SpaceX engineers, helped decentralize internet infrastructure with Starlink.
“We’ve seen this paradigm shift coming out of Starlink that traditional, large, centralized, systems are very expensive,” Vital Lyfe CEO Jon Criss told me. “They’re hard to deploy and hard to scale up when you really need them.”
After raising a $24 million seed round in December, the startup launched its first product a few weeks ago, which retails for $750. At that price point, it’s a great deal for sailors spending days or weeks at sea, but likely too expensive for the individuals in remote communities far from water infrastructure that might need it most. Criss’s goal is to quickly iterate on this first product to bring more affordable models to the market in short order.
Portable desalination devices aren’t anything new in and of themselves — they’ve been used in military, maritime, and humanitarian scenarios for decades. The startup’s breakthrough, Criss explained, is more about manufacturing efficiency than technology. “We went all the way back, looked at why every component was designed and how to redesign it for high rate manufacturing. So we were able to substantially drop the cost of ownership and operation of these things.”
You’ll soon find Vital Lyfe’s product in big box retail stores, Criss said, though he also aims to partner with large-scale desalination facilities and utilities to help boost their output. Either way, the startup is already generating buzz — it’s seen significant inbound interest as of late, as the inherent resilience of its small system stands in sharp contrast to the vulnerability of conventional desalination infrastructure now being targeted in the Middle East.
The company is scaling up to meet the moment, building out a facility in Los Angeles county that Criss said will eventually produce 120 portable units per hour. He’s aiming to start production by summer’s end, ramping to full capacity by October. “Within the next three years we plan to account for about 10% of total membrane production at Vital Lyfe alone,” he told me, referring specifically to the production for the desalination industry.
The future of the industry, of course, could look like any combination of all of these approaches — portable devices, conventional plants on land, and modular systems at sea. What seems certain is that as the globe continues to heat up, so will desalination tech.
Why local governments are getting an earful about “infrasound”
As the data center boom pressures counties, cities, and towns into fights over noise, the trickiest tone local officials are starting to hear complaints about is one they can’t even hear – a low-frequency rumble known as infrasound.
Infrasound is a phenomenon best described as sounds so low, they’re inaudible. These are the sorts of vibrations and pressure at the heart of earthquakes and volcanic activity. Infrasound can be anything from the waves shot out from a sonic boom or an explosion to very minute changes in air pressure around HVAC systems or refrigerators.
Knowing some of these facilities also have the capacity to produce significant audible noise, growing segments of the population’s more tech-skeptical and health-anxious corners are fretting some data centers could be making a lot of infrasound, too. The whizzing of so many large computational machines combined with cooling fans and other large devices creating so many new columns of air flow. Add onto that any rotational onsite power generation – think natural gas turbines, for example – and you get quite a lot of movement that could potentially produce what they say is infrasound.
Some of the virality of this chatter about infrasound and data centers comes from a video about infrasound created by audio engineer and researcher Benn Jordan. Currently sitting at more than 1 million views, this short YouTube film documents claims that some data centers are operating like “acoustic weapons” through infrasound and harming people. Andy Masley, an “effective altruist” writer, has become the chief critic of the Jordan video, getting into a back-and-forth that’s raised the issue to Internet discourse territory.
The Jordan-Masley infrasound debate is honestly a bit of a mess. So I want to be clear: I’m not going to get into the science of whether or not infrasound poses any kind of public health risk in this article. We can get to that later. It’s worth saying that this subject may need more study and that work is ongoing. Also, talking about infrasound at all can make you honestly sound a little wacky (see: this study blaming people seeing ghosts on infrasound). It might also remind you of another panic in the Electric Age: electromagnetic fields, also known as EMFs. Developers of transmission lines and solar projects have long had to deal with people worried about transmission lines and large electrical equipment potentially glowing with invisible, unhealthy radiation.
In late 2024, I wrote about how an RFK Jr. supporter worried about this form of electrical emission was helping lead the fight against a transmission line in New Jersey for offshore wind. Maybe that’s why it didn’t surprise me one bit when the Health and Human Services secretary himself told a U.S. Senate Committee last week that he was asking the Surgeon General’s office to “do either meta reviews” or “base studies” on noise pollution and EMF radiation from data centers “so we can better inform the American public.”
“There’s a range of injuries that are very, very well documented. They’re neurological – very, very grave neurological injuries, cancer risk,” Kennedy Jr. told the Senate Health, Education, Labor and Pensions Committee on April 22 in response to a request from Sen. Josh Hawley of Missouri to study the issue. “The risks, to me, are tremendous.”
There’s also the unfortunate reality that infrasound impacts have previously been a cudgel to slow down renewable energy deployment. Wind turbines create infrasound because of the subharmonic frequencies created when one turbine rotates at a slightly different pace than another, producing a slightly dissonant low frequency noise. Groups like the Heartland Institute proudly list this infrasound as one of the reasons wind energy “menaces man and nature.”
But regardless of merit, this concern is already impacting local government decisions around data center projects, much like how one Michigan county sought to restrict solar energy on the same basis.
In February Adrian Shelley, the Texas director for environmental group Public Citizen, implored the city of Red Rock to study changing their noise ordinance to take into account infrasound. “It has effects on sleep patterns, on stress, on cardiovascular health, and it is potentially a very serious concern,” Shelley said at a February 11 city council discussion on data center rules. “It will not be covered by the city’s noise ordinance, which only deals with audible sound.”
Earlier this month in Calvert County, Maryland, a volunteer for their environmental commission recently told the county government that infrasound needs to be factored into their future data center planning. “It will have significant impacts on our region and the Chesapeake and the Patuxent because infrasound isn’t stopped by walls,” commission member Janette Wysocki, a proud land conservationist, said at an April 15 hearing. “It will keep going, it will move through anything. It’s a very long wavelength. So we need to protect our ecosystem.” Wysocki implored the county to consider whether to adjust its noise regulations.
Around the same time, similar concerns were raised in Lebanon, a small city in east-central Pennsylvania. “It permeates through concrete walls, it permeates through the ground,” Thomas Dompier, an associate professor at Lebanon Valley College, said at an April 16 Lebanon County commission hearing on data centers.
Lastly, last week I explained how Loudon County wants to rethink its noise ordinance to deal with low-frequency “hums” from data centers – a concern echoing those who fret infrasound.
Ethan Bourdeau, executive director of standards at Quiet Parks Intentional and a career acoustician and building standards writer, told me that what makes data centers unique is the “constant drone” of noise that could potentially carry subharmonic frequencies. Bourdeau said cities or counties could possibly factor concerns about infrasound into noise ordinances to address those who are most concerned. One way they could do it is by changing how decibels are weighted in the government’s measurements. A-weighting decibel meters are a common form of sound measurement geared toward perceptible noise. Using different systems, like C-weighting or G-weighting, would avoid ways that A-weighting can filter out sub-hearing frequencies.
“These are reporting and weighting systems where a sound level meter taking background noise receives all the unweighted sound and then you apply all these filters afterwards, like an EQ curve,” Bourdeau said.
So I guess if those most concerned about infrasound have their way, a lot of country commissioners and local elected leaders will be heading to the mixing booth.
