They look like a weapon. They work like a weapon. But they could save countless lives.
I confess that when I first heard about flamethrowing drones, I did not think they sounded like a good idea.
Being an American sometimes means learning that flamethrowers can get marked down for Black Friday (25% off! Bitcoin accepted!) and that a device that shoots literal fire is “not considered a firearm” in the United States. These discoveries did not leave me with the best first impression; drones struck me as untrustworthy enough before I learned they were being rigged to ignite things.
But for all that they sounds like they belong in a supervillain’s arsenal, fire-starting drones could also save countless lives. That’s because unmanned vehicles — especially ones that fly — just might be the next frontier in wildland firefighting.
“It’s still pretty new technology and there’s a long way to go before it’s being used everywhere,” Carrick Detweiler, the CEO and co-founder of Drone Amplified, stressed to me. He and his team of computer science and engineering professors and alums from the University of Nebraska-Lincoln are focused on supplying major fire agencies with devices that can be used to safely conduct backburns and prescribed burns. They already have “hundreds” of such drones out in the field, with clients including the U.S. Forest Service and the Bureau of Land Management, as well as comparable fire agencies in Canada, Australia, and New Zealand.
Rather than mount a whole flamethrower to a drone, the Drone Amplified device works by dropping small potassium permanganate shells that had been injected with anti-freeze, causing the shells to ignite, over a landscape. (The shells are known as “dragon eggs.”) This allows fire agencies to conduct controlled low-intensity burns in hard-to-reach locations to limit the available fuel for future wildfires. It also allows firefighters to start what are known as backburns, defensive “counter-fires” of last resort that block an advancing wildfire from moving into a new landscape, and that are traditionally started by hand with dip torches.

Most important of all, though, Drone Amplified’s invention keeps the skies above wildfires in the domain of unmanned aircraft. Already this month in Australia, where wildfire season is just beginning, a fire-mapping plane crashed, killing all three people on board, including a 22-year-old New Yorker. In the U.S. this summer, a helicopter collision in California killed an additional three who’d been attending to a grass fire. By the CDC’s measure, about a quarter of all firefighting deaths are aviation-related; according to High Country News, 37 firefighters died in aerial accidents between 2005 and 2015, meaning “more than 200 ground firefighters would die every year” if earthbound casualty rates were the same.
“A bushfire creates its own weather system, right?” Adrian Hollis of the Perth-based digital technology company Remsense, which is developing an aerial ignition system to rival Drone Amplified’s in Australia, explained to me. The heat from a wildfire creates an updraft, which in addition to natural weather conditions, can result in “a lot of wind shear,” Hollis went on. “And because you are fighting a fire, you’re so low [in a plane or helicopter] that you’ve got no recovery altitude. So if you go into a stall or something happens, you’ve got no height to get out of trouble. That’s why it’s so dangerous.”
With wildfires being so unpredictable and deadly, you’d think there would have already been more advances in firefighting drones and robotics. But what makes fires so complicated for humans to fight also makes them difficult for the equipment. “The environment of fighting fires is probably one of the most challenging environments for any technology,” Carlos Viegas, a mechanical engineer at Portugal’s University of Coimbra and the head of the school’s Field Tech Lab, told me.
Viegas’ specialty when it comes to drone payload isn’t fire; it’s water. In Portugal, where backburning is less common, he’s helped to invent a drone that will drag a fire hose to douse hard-to-reach or dangerous fires, the design of which required overcoming the same obstacles of high heat, low visibility, ashy air, and unpredictable weather conditions that a fire-dropping drone might encounter. “This is why we are still fighting fires the way we used to fight for the last 50 or 100 years, almost,” he said of the tough conditions engineers have to overcome in drone design. “The progress, in this case, it’s very slow.”
Beyond safety concerns, there are, of course, financial and logistical considerations compelling the advancements, too. Wildfires aren’t always cooperative, for one thing; they often start in areas where it’s hard — or expensive — to shuttle people to the site. In Hollis’ line of work, in Australia, responding to a wildfire might require transporting fuel, a helicopter, and staff hundreds of miles into remote or roadless terrain, all of which makes a drone that weighs only about as much as a small golden retriever when fully loaded far more appealing.
A drone is also cheaper. One of Drone Amplified’s Alta X’s, outfitted with the Ignis fire-starting system, runs around $80,000, which might sound expensive if you’re an, um, home flame-throwing enthusiast, but for a fire agency, “the alternative is a helicopter that costs $10,000 to $20,000 a day to operate,” Detweiler said. “And then the added risk of the people who are up in helicopters.” The price tag has the further benefit of deterring pyromaniacs; though anyone can technically buy one of Drone Amplified’s products, which the FAA has carved out a dangerous weapon exemption for, Detweiler reassuringly pointed out that “few people have $80,000 just to spend” and “we do have pretty in-depth discussions, and we do trainings, with users.”
Besides, the people the drone really needs to win over are the firefighters, who are understandably distrustful of newfangled gadgets that could quit on them in a life-or-death situation. But according to Detweiler, they are coming around: “It’s been really exciting to see just how the fire community has started to embrace these new technologies because historically, they’re putting their lives on the line and they trust their shovel and their chainsaw,” he said. “New technology really needs to work to get them to start adopting it.”
It might also, one day, make them obsolete. Already, drones are being used for fire surveillance and mapping, and Viegas, the Portuguese mechanical engineer, showed me videos of other autonomous systems the Field Tech Lab is pioneering, including a mini bulldozer that can dig a fireline and drones equipped with remote sensors that can tell when a landscape is becoming overgrown, and thus more fire-prone, long before people on the ground can.
On the one hand, it’s incredible to be on the cusp of this moment, where a technology shift could save hundreds of firefighters’ lives by taking them out of difficult, dangerous landscapes in the decades to come. On the other — and as the existence of an online flamethrower retailer perhaps implies — these are powerful tools in the wrong hands, too. Armchair drone enthusiasts have already scuttled wildfire suppression efforts by flying cameras over burns, grounding official aerial fire missions in the process, not to mention that some 89% of wildfires are started by people. I don’t have an enormous amount of trust that someone, somewhere, won’t do something dumb with an expensive toy.
But the upsides certainly outweigh any edge cases my overactive imagination can dream up. Viegas, for one, sees only upsides: “I firmly believe that we are working towards a solution where we won’t need any firefighters in the terrain — we will just fight fires with unmanned means,” he said.
And while the “dangerous weapon” parallel is never too far away from something like a fire-starting drone, he suggested the embrace of the technology requires a simple reframe of the enemy. “In the war, you are seeing already everything is done by drones,” Viegas said. “I believe that in the war against fires, it’s going to be the same as well.”

Did a battery plant disaster in California spark a PR crisis on the East Coast?
Battery fire fears are fomenting a storage backlash in New York City – and it risks turning into fresh PR hell for the industry.
Aggrieved neighbors, anti-BESS activists, and Republican politicians are galvanizing more opposition to battery storage in pockets of the five boroughs where development is actually happening, capturing rapt attention from other residents as well as members of the media. In Staten Island, a petition against a NineDot Energy battery project has received more than 1,300 signatures in a little over two months. Two weeks ago, advocates – backed by representatives of local politicians including Rep. Nicole Mallitokis – swarmed a public meeting on the project, getting a local community board to vote unanimously against the project.
According to Heatmap Pro’s proprietary modeling of local opinion around battery storage, there are likely twice as many strong opponents than strong supporters in the area:

Yesterday, leaders in the Queens community of Hempstead enacted a year-long ban on BESS for at least a year after GOP Rep. Anthony D’Esposito, other local politicians, and a slew of aggrieved residents testified in favor of a moratorium. The day before, officials in the Long Island town of Southampton said at a public meeting they were ready to extend their battery storage ban until they enshrined a more restrictive development code – even as many energy companies testified against doing so, including NineDot and solar plus storage developer Key Capture Energy. Yonkers also recently extended its own battery moratorium.
This flurry of activity follows the Moss Landing battery plant fire in California, a rather exceptional event caused by tech that was extremely old and a battery chemistry that is no longer popular in the sector. But opponents of battery storage don’t care – they’re telling their friends to stop the community from becoming the next Moss Landing. The longer this goes on without a fulsome, strident response from the industry, the more communities may rally against them. Making matters even worse, as I explained in The Fight earlier this year, we’re seeing battery fire concerns impact solar projects too.
“This is a huge problem for solar. If [fires] start regularly happening, communities are going to say hey, you can’t put that there,” Derek Chase, CEO of battery fire smoke detection tech company OnSight Technologies, told me at Intersolar this week. “It’s going to be really detrimental.”
I’ve long worried New York City in particular may be a powder keg for the battery storage sector given its omnipresence as a popular media environment. If it happens in New York, the rest of the world learns about it.
I feel like the power of the New York media environment is not lost on Staten Island borough president Vito Fossella, a de facto leader of the anti-BESS movement in the boroughs. Last fall I interviewed Fossella, whose rhetorical strategy often leans on painting Staten Island as an overburdened community. (At least 13 battery storage projects have been in the works in Staten Island according to recent reporting. Fossella claims that is far more than any amount proposed elsewhere in the city.) He often points to battery blazes that happen elsewhere in the country, as well as fears about lithium-ion scooters that have caught fire. His goal is to enact very large setback distance requirements for battery storage, at a minimum.
“You can still put them throughout the city but you can’t put them next to people’s homes – what happens if one of these goes on fire next to a gas station,” he told me at the time, chalking the wider city government’s reluctance to capitulate on batteries to a “political problem.”
Well, I’m going to hold my breath for the real political problem in waiting – the inevitable backlash that happens when Mallitokis, D’Esposito, and others take this fight to Congress and the national stage. I bet that’s probably why American Clean Power just sent me a notice for a press briefing on battery safety next week …
And more of the week’s top conflicts around renewable energy.
1. Queen Anne’s County, Maryland – They really don’t want you to sign a solar lease out in the rural parts of this otherwise very pro-renewables state.
2. Logan County, Ohio – Staff for the Ohio Power Siting Board have recommended it reject Open Road Renewables’ Grange Solar agrivoltaics project.
3. Bandera County, Texas – On a slightly brighter note for solar, it appears that Pine Gate Renewables’ Rio Lago solar project might just be safe from county restrictions.
Here’s what else we’re watching…
In Illinois, Armoracia Solar is struggling to get necessary permits from Madison County.
In Kentucky, the mayor of Lexington is getting into a public spat with East Kentucky Power Cooperative over solar.
In Michigan, Livingston County is now backing the legal challenge to Michigan’s state permitting primacy law.
On the week’s top news around renewable energy policy.
1. IRA funding freeze update – Money is starting to get out the door, finally: the EPA unfroze most of its climate grant funding it had paused after Trump entered office.
2. Scalpel vs. sledgehammer – House Speaker Mike Johnson signaled Republicans in Congress may take a broader approach to repealing the Inflation Reduction Act than previously expected in tax talks.
3. Endangerment in danger – The EPA is reportedly urging the White House to back reversing its 2009 “endangerment” finding on air pollutants and climate change, a linchpin in the agency’s overall CO2 and climate regulatory scheme.
