The founder of Impulse Labs explains why he wants to put a battery in every appliance.
Impulse Labs debuted its much anticipated induction stove at the Consumer Electronics Show in Las Vegas this week. Coming to grips with this high-tech culinary wonder is a little bit like that meme of an expanding brain.
At first glance, the Impulse Cooktop is just a sexy-looking, $5,999 appliance: sleek black glass, burners that resemble a DJ turntable, knobs that add a satisfying analog touch to an otherwise fully digital interface.
But then you learn it also has integrated temperature sensors that keep the burners at the precise temperature you want.
And then you learn that the stove has a battery in it, which means that unlike most other induction stoves, it can plug into a standard 120-volt outlet. You don’t have to get a pricy circuit upgrade, or an even pricier electrical panel upgrade, to install it.
Plus, the battery delivers enough power to boil a liter of water in 40 seconds. And you can still cook if the power goes out. And its eligible for a 30% tax credit .
And then, your brain explodes when you learn the battery is a smart energy storage device that can charge up when power is cheap in the morning so that you save money when you use it in the evening, when power prices are highest. You can also participate in programs that will pay you to dispatch power from your stove to the grid when demand is high.
Who knew a stove could, or should, do so much?

I caught up with Sam D’Amico, the mastermind behind Impulse Labs, while he was at CES, to learn more about the story behind the stove. We talked about pizza, why induction cooking is the wedge to getting whole homes off gas, and his vision for putting a battery in every appliance. Our conversation has been lightly edited for clarity.
What’s your background? What were you up to before founding Impulse?
I graduated Stanford in 2012. In 2013 I got my masters. When I was there, I was on the solar car team and actually wrote battery management firmware as part of that. That gave me my first taste in electrification. You had to build a full EV and drive it across Australia. Then I immediately got sucked into consumer electronics and worked on a number of devices, including Google Glass, Oculus.
Part of the thesis for Impulse is, home appliances really haven’t seen a lot of innovation in 50 years or so. There’s been a number of advances in consumer electronics, so being able to take a lot of the talent and supply chain and experience from that and apply it to the appliance space is underleveraged.
You were working on all these computer electronics, and then somehow you got interested in stoves. I understand it had something to do with making the perfect pizza. Could you tell me that story?
I was in Japan at a conference, and we went to this pizza place and they cooked my pizza in like 45 seconds. And I’m like, that is insane. I think it’s called Savoy Pizza, you should definitely go to it. Tastiest pizza I’ve ever had. Super memorable. And then I’m like, I want to do that. But can I make it a tabletop device in my house?
And so I was getting obsessive with how to replicate that, but I realized you couldn’t do it on a 120-volt plug. I basically realized you had to put a battery in the appliance to be able to boost the power above what a 120 volt provides. All of the oven and smart appliance companies were really focused on AI and computer vision at that time, because they couldn’t innovate on the performance characteristics — they were topped out. And I realized this was an end run around that. You could actually make something that was three times better on the performance side, not have to worry about AI features that maybe no one is going to use, and really do some innovation.
That started me thinking about the bigger picture. I realized you could use that storage for the building. And then that kind of expanded into what became Impulse.
Did you figure out how to cook a pizza in 45 seconds?
So the first product is a cooktop. The idea here was we realized that the key appliance to getting gas out of the home was the stove. People don’t know what the fuel source is for all of their other appliances, including ovens. The big thing with gas stoves is that the user experience is the flame. So being able to address that, we thought, was fundamental to building decarbonization.
Utility companies know this. They know that getting people to get a gas stove is the way to get them off electric heat and on to gas heat. The wedge is actually the gas stove. So by producing an appliance that is just way more compelling, we can sever that dependency.
When we do an oven, I think we will have that pizza feature. I think the ballpark of performance of around 45 seconds is possible.
What was the process like of testing stoves and trying to figure out what the perfect stove is?
That was the fun part. We started buying hot plates and stoves and tearing them down. We basically realized that a lot of this stuff just hadn’t been attempted because the power wasn’t available. So the first thing we did was try to crank a ton of power into the stove. So we were like, let’s do 10 kilowatts, because 10 is a big number. That let us boil a liter of water in 40 seconds. We had that demo working in March or April of 2022.
But we realized immediately that this was too much performance unless you could solve the controls problem. The reason why people complain about warped pans and various other things is because the stove gets too hot. We then started tearing down all the hot plates and stoves we could find that had temperature sensors in them, and we realized that no one’s actually addressed this, and we found that there was a lot of leverage there that let us unlock the full performance of the stove. And so we’re monitoring the temperature in real time, making sure that we’re delivering the appropriate amount of power for the level you want to set, so that it holds a specific temperature.
If you need to use your stove all day, like for cooking a whole Thanksgiving dinner, is that possible with this? Or will the battery drain and then you can’t use it for a little bit?
You’re going to be okay, yes. You’ll drain the battery if you’re, let’s say, boiling a big pot of water for pasta. But then once it’s at temperature, you’re not going to be drawing more than what a 120-volt plug would draw. Maybe you’re stir-frying something. That pan, when it’s heating up, maybe it’s drawing a couple kilowatts for a minute, but then once everything’s up to temperature, you’re drawing hundreds of watts, and the battery is charging.
So basically, the average power draw [when you cook] is appropriate for even a 120-volt plug. It’s just that the peak power is more like an EV charger, or like an electric radiant heater, or something crazy. And that mismatch between peak and average is where the opportunity for putting batteries in appliances really shines.
The battery is like a quarter of a Tesla Powerwall. How valuable can that be for the grid?
There’s a couple of ways to weigh how valuable that is. In Southern California, which has really strong time-of-use energy rates, in the 4 to 9 pm slot, [using electricity during] that peak window is like 20 cents more expensive per kilowatt-hour than outside that window. So if you charge the battery outside the window and then you discharge the battery, whether it’s cooking or it’s putting power back into the house, inside that window, it’s worth hundreds of dollars a year in terms of energy bill savings.
We’ve got a full computer in there. It will basically pull those rate tables and make those choices semi-autonomously. We’re likely going to expose some level of choice to the end user, but we haven’t finalized the design.
What’s your pitch to the average consumer? How do you get people interested in having batteries in their appliances?
I think there’s a very direct pitch, which is, we are making the best possible appliances. It will make you a better cook. You will be able to do things faster and more efficiently.
Two is, you will be like, “I want to get an induction stove, I heard that’s a good thing to get.” And then your electricians will come by and tell you that you only have 10 amps available on your electric panel, and you’re going to be sad. And so we also solve that problem.
And then the third one is, now we’ve put some energy storage in your house. There’s 140 million homes in America. If we can intercept three major appliances per home, or four major appliances per home, that’s like 1.4 terawatt-hours of storage deployment potential. There’s an opportunity to deploy storage every year just by people upgrading their appliances. And so that’s part of the end game. Utilities will like that because it means they don’t have to invest in all this expensive transmission infrastructure.
Do you want to make other products besides stoves?
Yeah. We want to make the best appliances across the board. There’s a number of logical options, anything that has high peak but low average draw is the low hanging fruit. So you can imagine ovens — they draw power when they pre-heat. Water heaters are another one, where it’s like, if you’re taking a shower, it consumes a ton of power, but when you’re not, it doesn’t. Laundry is another one. I also want to emphasize that we’re making relatively high-end, premium appliances to start, but this architecture scales down fairly well to mid-range products. It’s just that as a startup, just as Tesla started with sports cars, we have to kind of start with the lower-volume, higher-margin products and then scale up from there.
How do people get one?
You can preorder it today on ImpulseLabs.com. There’s about 45% in federal discounts available. Because this thing has a battery and an inverter, it’s an energy storage product. It gets a 30% investment tax credit. A big change under the IRA was that stationary batteries, sold separately from solar, get that credit now. And then there’s also an $840 electric stove rebate that is available under the IRA. That one is income gated and expected to roll out in the fall. Our products are going to be available in Q4, so we expect the timing to be appropriate where all those rebates and credits will be available.

On storm damage, the Strait of Hormuz, and Volkswagen’s robotaxi
Current conditions: A dangerous heat dome is forming over central states today and will move progressively eastward over the next week • Wildfire warnings have been issued in London • Typhoon Wutip brought the worst flooding in a century to China’s southern province of Guangdong.
Hurricane Erick made landfall as a Category 3 storm on Mexico’s Pacific coast yesterday with maximum sustained winds around 125 mph. Damages are reported in Oaxaca and Guerrero. The storm is dissipating now, but it could drop up to 6 inches of rain in some parts of Mexico and trigger life-threatening flooding and mudslides, according to the National Hurricane Center. Erick is the earliest major hurricane to make landfall on Mexico's Pacific coast, and one of the fastest-intensifying storms on record: It strengthen from a tropical storm to a Category 4 storm in just 24 hours, a pattern of rapid intensification that is becoming more common as the Earth warms due to human-caused climate change. As meteorologist and hurricane expert Michael Lowry noted, Mexico’s Pacific coast was “previously unfamiliar with strong hurricanes” but has been battered by epic storms over the last two years. Acapulco is still recovering from Category 5 Hurricane Otis, which struck in late 2023.

An oil tanker collision near the Strait of Hormuz is raising environmental and security concerns. The accident in the Gulf of Oman involved the Adalynn and Front Eagle tankers. It caused a “small oil spill,” according to the Emirati government, but Greenpeace analyzed satellite images and said the oil plume stretches some six square miles from the collision site. “This is just one of many dangerous incidents to take place in the past years,” said Greenpeace campaigner Farah Al Hattab. The Strait of Hormuz is a choke point for oil shipments, with about one-third of the volume of crude exported by sea moving through that route. Oil prices have been on a roller coaster ride since Israel launched airstrikes against Iran on June 13. Ships in the region have been reporting more GPS navigation interference in recent days. “If the conflict continues, we expect these interferences to continue as well,” Jean-Charles Gordon, senior director of ship tracking at research firm Kpler, toldThe New York Times.
North Carolina lawmakers finalized a bill repealing a mandate that directs electric regulators to reduce their carbon dioxide emissions by 70% by 2030. The mandate was part of a landmark 2021 law aimed at dramatically reducing the state’s power plant emissions. While at least 17 other states have similar laws in place, just two – North Carolina and Virginia – are in the Southeast. The new bill’s supporters say that the interim emissions goal would require energy providers to switch to more expensive power sources and that the costs would be passed on to consumers in the form of higher power bills.
Confusingly, regulators would still be asked to work toward carbon neutrality by 2050, even while the short-term emissions goal might be nixed. “Not having any target, even an aspirational target, could mean that we don’t stay on track to get to our 2050 goal,” Democratic Sen. Julie Mayfield said. The bill now goes to Democratic Gov. Josh Stein’s desk. There’s a chance he might veto it, but “with over a dozen House and Senate Democrats voting for the final version, the chances that any Stein veto could be overridden are higher,” The Associated Pressreported.
The United Kingdom issued long-awaited environmental guidance that it will use to determine whether new oil and gas proposals should be approved. The guidance requires that developers estimate and include scope 3 emissions – or the downstream pollution from burning oil and gas – in their drilling applications. This “will ensure the full effects of fossil fuel extraction on the environment are recognized in consenting decisions,” the Department for Energy Security and Net Zero said. The government will consider these emissions, as well as other factors like “the potential economic impact” of a project and a company’s efforts to remove carbon dioxide when granting or denying approval. The guidance will help determine whether major new drilling projects from oil giants Shell and Equinor are approved for the North Sea.
Volkswagen Group unveiled its first fully autonomous production vehicle, the ID. Buzz AD. The electric robotaxis will target corporate customers and mobility services. They “come packed with everything that’s needed to operate them,” explained Iulian Dnistran at InsideEVs. “What makes this solution interesting compared to other ride-hailing platforms is that it enables anybody to start an Uber or Waymo rival without investing hundreds of millions of dollars in research, development, and certification.” The shuttles are slated for launch across Europe and the U.S. next year. Tesla recently announced that its first Robotaxis would hit the streets in Austin, Texas, sometime this month.

In a new peer-reviewed paper published in the journal Communications Earth & Environment, researchers conclude that offsetting the potential carbon emissions from reserves held by the world’s 200 largest fossil fuel companies would require planting new forests that are larger than the entire continent of North America.
The energy secretary's philosophy is all over the Senate mega-bill.
As the Senate Finance Committee worked on its version of the reconciliation bill that would, among things, overhaul the Inflation Reduction Act, there was much speculation among observers that there could be a carve out for sources of power like geothermal, hydropower, and nuclear, which provide steady generation and tend to be more popular among Republicans, along the lines of the slightly better treatment received by advanced nuclear in the House bill.
Instead, the Senate Finance Committee’s text didn’t carve out these “firm” sources of power, it carved out solar and wind, preserving tax credits for everything else through 2035, while sunsetting solar and wind by 2028.
For much of the last few months — and for years before he was sworn in as Secretary of Energy — Chris Wright has been expounding on his philosophy of energy and climate. If anything, the Senate Finance draft seems to hew closer to Wright’s worldview than Trump’s, which is less specific, even more critical of renewables (especially wind), and largely in favor of nuclear power when it comes to non-carbon-emitting generation.
“I’m sure Secretary Wright’s strong support for firm technologies over the past few months played a role in Chairman Crapo’s approach to energy tax credit reform,” Pavan Venkatakrishnan, an infrastructure fellow at the Institute for Progress, told me.
Wright argues that climate change is real but not a top-tier concern and that it certainly should not be addressed by restricting energy usage, which he sees as foundational to the good life here and abroad.
And among energy sources, the former fracking executive is no opponent of fossil fuels but is also enthusiastic about energy innovation.
In his company Liberty Energy’s Bettering Human Lives report, published last year, which doubles as a kind of manifesto, Wright wrote that “viable paths to reducing greenhouse gas (GHG) emissions can only come from reliable and affordable low-carbon energy technologies,” and specifically listed next-generation nuclear and geothermal, which Liberty had invested in through the geothermal company Fervo and nuclear company Oklo.
“To achieve largescale human betterment, we will need significant future energy additions from nuclear, hydropower, geothermal, and all other viable energy technologies,” the report read.
And he’s often been skeptical of renewables along the lines of many Congressional Republicans, that they aren’t reliable enough and require additional resources to fully support the grid.
“Maybe the biggest problem is intermittency,” Wright said at a Liberty Energy event last year.
“You can build a lot of wind and solar, and then at night, the sun’s not shining and then sometimes the wind doesn’t blow, and you have no energy. So to keep society running, you have to have a whole second separate energy system,” Wright said.
In testimony to the House of Representatives last week, Wright said “If you’re not there at peak demand, you’re just a parasite on the grid, because you just make the other sources turn up and down as you come and go.”
Many critics of the Republican reconciliation bills have noted that much of the electricity generation pipeline is solar, wind, or storage, and so cutting off their tax credits risks leaving the country at an energy shortage while gas turbines take years and years to actually get on the grid.
But as Congress was working on the reconciliation bill, Wright made a series of widely noted public appearances where he promoted clean firm power and continued government support for it.
“My recommendation has been to leave behind the equivalent of the wind and solar tax credits — through if you start construction by 2031 — for nuclear fission and fusion and geothermal,” Wright said at an event earlier this month.
In May, Wright addressed the Nuclear Energy Institute, outlining his support for sunsetting wind and solar tax credits will working to kickstart nuclear power. “My personal goal would be to much more rapidly sunset the technologies that have been around and have been living on decades of subsidies,” Wright said. He also supported a “window” of “favorable treatment” for nuclear and geothermal.
“I’m in favor of every nudge, every incentive we can get from the federal government to restart this industry,” Wright said.
While Wright has been skeptical of wind and solar and optimistic about nuclear and geothermal for years, he’s also started talking more positively about energy storage. In the past, he’s talked up hydrocarbons for “coming with their own storage,” as he put it in a 2018 podcast.
But at an appearance at ARPA-E in March, Wright gave some of his most extended thoughts on energy storage, which sits somewhat awkwardly between variable resources like solar and wind and firm resources like nuclear and geothermal.
“Solar is growing very fast, getting more efficient and taking panels, cheaper materials and developing energy,” Wright said. “The biggest problem there is the sun doesn’t always shine, and we don’t know when clouds are going to come and when it’s not going to shine, but if we can get energy storage better, that’s a game changer.”
At least until 2035.
When I reached out to climate tech investors on Tuesday to gauge their reaction to the Senate’s proposed overhaul of the clean energy tax credits, I thought I might get a standard dose of can-do investor optimism. Though the proposal from the Senate Finance committee would cut tax credits for wind and solar, it would preserve them for other sources of clean energy, such as geothermal, nuclear, and batteries — areas of significant focus and investment for many climate-focused venture firms.
But the vibe ended up being fairly divided. While many investors expressed cautious optimism about what this latest text could mean for their particular portfolio companies, others worried that by slashing incentives for solar and wind, the bill’s implications for the energy transition at large would be categorically terrible.
“We have investments in nuclear, we have investments in geothermal, we have investments in carbon capture. All of that stuff is probably going to get a boost from this, because so much money is going to be flowing out of quote, unquote, ‘slightly more established’ zero emissions technologies,” Susan Su, a climate tech investor at Toba Capital, told me. “So we’re diversified. But for me, as a human being, and as somebody that cares about climate change and cares about having an abundant energy future, this is very short-sighted.”
Bigger picture aside, the idea that the Senate proposal could lead to more capital for non-solar, non-wind clean energy technologies was shared by other investors, many of whom responded with tentative hope when I asked for their thoughts on the bill.
“The extension of the nuclear and geothermal tax credits compared to the House bill is really important,” Rachel Slaybaugh, a climate tech investor at DCVC, told me. The venture firm has invested in the nuclear fission company Radiant Nuclear, the fusion company Zap Energy, and the geothermal startup Fervo Energy. As for how Slaybaugh has been feeling since the bill’s passage as well as the general sentiment among DCVC’s portfolio companies, she told me that “it's mostly been the relief of like, thank you for at least supporting clean, firm and bringing transferability back.”
Indeed, the proposed bill not only fully preserves tax credits for most forms of zero-emissions power until 2034, but also keeps tax credit transferability on the books. This financing mechanism is essential for renewable energy developers who cannot fully utilize the tax credits themselves, as it allows them to sell credits to other companies for cash. All of this puts nascent clean, firm technologies on far more stable footing than after the House’s version of the bill was released last month.
Carmichael Roberts of Breakthrough Energy Ventures echoed these sentiments via email when he told me, “the Senate proposal is a meaningful improvement over the House version for clean energy companies. It creates more predictability and a clearer runway for emerging technologies that are not yet fully commercial.” Breakthrough invests in multiple fusion, geothermal, and long-duration energy storage startups.
Amy Duffuor, co-founder and general partner at Azolla Ventures, also acknowledged in an email that it’s “encouraging” that the Senate has “seen the way forward on clean firm baseload power.” However, she issued a warning that the unsettled policy environment is leading to “material risks and uncertainties for start-ups reliant on current tax incentives.”
Solar and wind are by far the most widely deployed and cost-competitive forms of renewable energy. So while they now mainly exist outside the remit of venture firms, there are numerous climate-focused startups that operate downstream of this tech. Think about all the software companies working to optimize load forecasting, implement demand response programs, facilitate power purchase agreements, monitor grid assets, and so much more. By proxy, these startups are now threatened by the Senate’s proposal to phase out the investment and production tax credits for solar and wind projects beginning next year, with a full termination after 2027.
“I think solar and wind will survive. But it's going to be like 80% of the deals don't pencil for a long time,” Ryan Guay, co-founder and president of the software startup Euclid Power, told me. Euclid makes data management and workflow tools for renewable project developers, so if the tax credits for solar and wind go kaput, that will mean less business for them. In the meantime though, Guay expects to be especially busy as developers rush to build projects before their tax credit eligibility expires.
As Guay explained to me, it’s not just the rescission of tax credits that he believes will kill such a large percent of solar and wind projects. It’s the combined impact of those cuts, the bill’s foreign entity of concern rules restricting materials from China, and Trump’s tariffs on Chinese-made components. “You’re not giving the industry enough time to actually build that robust domestic supply chain, which I agree needs to happen,” Guay told me. “I’m all for the security of the grid, but our supply chains are already very constrained.”
Many investors also expressed frustration and confusion over why Senate Republicans, and the Trump administration at large, would target incentives for solar and wind — the fastest growing domestic energy sources — while touting an agenda of energy dominance and American leadership. Some even used the president’s own language around energy issues to deride the One Big Beautiful Bill’s treatment of solar and wind as well as its repeal of the electric vehicle tax credits.
“The rollbacks of the IRA weaken the U.S. in key areas like energy dominance and the auto industry, which is rapidly becoming synonymous with the EV industry,” Matt Eggers, a managing director at the climate-tech investment firm Prelude Ventures, wrote to me in an email. “This bill will still ultimately cost us economic growth, jobs, and strategic positioning on the world stage.”
“The only real question is, are we going to double down on the future and on American dynamism?” Andrew Beebe, managing director at Obvious Ventures, asked in an emailed response. “Or are we going to cling to the past by trying to hold back a future of abundant, clean, and affordable energy?”
Su wanted to focus on the bigger picture too. While the Senate’s proposal gives tax credits for solar and wind a much longer phaseout period than the House’s bill — which would have required projects to start construction within 60 days of the bill’s passage and enter service by 2028 — Su still doesn’t think the Senate’s version is much to celebrate.
“The specific changes that came through in the Senate version are really kind of nibbling at the edges and at the end of the day, this is a huge blow for our emissions trajectory,” Su told me. She’s always been a big believer that there’s still a significant amount of cutting edge innovation in the solar and wind sectors, she told me. For example, Toba is an investor in Swift Solar, a startup developing high-efficiency perovskite solar cells. Nixing tax credits that benefit the solar industry will hit these smaller players especially hard, she told me.
With the Senate now working to finalize the bill, investors agreed that the current proposal is certainly not the worst case scenario. But many did say it was worse than they had — perhaps overly optimistically — been holding out for.
“To me, it's really bad because it now has a major Senate stamp of approval,” Su told me. The Senate usually tempers the more extreme, partisan impulses of the House. Thus, the closer a bill gets to clearing the Senate, the closer it usually is to its final form. Now, it seems, the reconciliation bill is suddenly feeling very real for people.
“At least back between May 22 and [Monday], we didn't know what was going to get amended, so there was still this window of hope that things could change more dramatically." Su said. Now that window is slowly closing, and the picture of what incentives will — and won’t — survive is coming into greater focus.
