As California wildfire season nears, startup BurnBot is working on a high-tech approach to prevention

Last year’s record heat wave worsened drought and dry conditions across the globe, a particularly calamitous situation for California, which has seen 13 of the state’s 20 most destructive wildfires in history break out since 2017.
In South San Francisco, a small startup is working on a high-tech approach to wildfire prevention.
Anukool Lakhina and Waleed “Lee” Haddad founded BurnBot in 2022 to develop robotics and remote-controlled vehicles that can munch up and burn away invasive plants or other dry vegetation that can fuel fires if left fallow.
BurnBot has just raised a $20 million funding round led by climate-focused ReGen Ventures, for expansion, hiring, and to develop new machines that can traverse steeper hills and get into tighter spaces.
Before BurnBot, firefighters and land owners had to use expensive, time-consuming and more dangerous options like grazing away the vegetation (typically with goats), burning it, applying herbicides or removing vegetation mechanically with a mix of equipment and manual labor.
“The sort of traditional way to do a prescribed burn is with drip torches, and that requires a large number of people,” said Lakhina, BurnBot’s CEO. “A drip torch is like a diesel watering can. You go around, you drop diesel, then ignite it.”
Burnbot’s current model, the RX, is a remote-operated vehicle that looks a cross between an oversized Zamboni and a steel cooking range with a set of fire extinguishers strapped to its back. Like other agricultural and construction equipment, the RX rolls forward on tank-like tracks and wheels, which enable it to maneuver through rough fields.
Within the chambers of the RX are several rows of torches that emit blue flames, and adjust the heat levels precisely to zap away unwanted vegetation or other fuels on the ground below. The chambers of the BurnBot RX also trap and torch away the smoke that comes from burning vegetation, so it doesn’t pollute the air in surrounding communities. When the torching is done, the RX sprays water repeatedly to extinguish any remaining embers.

Lakhina said BurnBot’s systems can be put to use where traditional controlled burns won’t work. For example, drip torch burns produce a good deal of smoke, which is conductive enough it would interfere with the proper functioning of power lines or high-voltage equipment. BurnBot’s machines can be used even under power lines.
The company is aiming to make every person who works in fire prevention 10 times more effective than they were with old methods, Lakhina said.
Haddad, BurnBot’s chief technology officer, noted that land isn’t always ready to “receive fire” in a prescribed burn. So the company has programmed equipment, which it procures from another supplier, to roll ahead of the RX to crunch up the vegetation in an area of concern before it’s ready for torching.
BurnBot plans to conduct a prescribed burn this Friday in San Diego, a project for CalTrans, the state’s transportation agency. It also plans for another burn for Pacific Gas & Electric, the state’s major utility, in June.
PG&E spends upward of $1 billion on “vegetation management” each year. Kevin Johnson, who leads the company’s Wildfire Resilience Partnerships, said PG&E is always “looking for opportunities to do this work safer, faster, cheaper and to be more environmentally friendly.”
BurnBot has already completed one demonstration of its controlled burn machine underneath PG&E transmission lines.
Brice Muenzer, a battalion chief with CalFire in Monterey, California, said massive fires in the state and throughout the U.S. over the past decade have been partly caused and certainly exacerbated by overzealous elimination of smaller fires, including ritual fires from indigenous communities.
“We removed fire from the ecosystem for the last 150 years and are living through that reality now,” the chief said.
CalFire has worked with BurnBot personnel, machines and additional drones overhead, to create what’s known as a control line in the field in at least one location. Muenzer says the group hopes to do more with the startup.
Creating a control line, or blacklining the land, involves firefighters strategically burning areas when the weather is calm and where flames can be controlled to create scars that will block other fires from jumping in and reaching areas with lots of new material to burn.

BurnBot aims to eventually expand its operations beyond California, with offices and fleets of its machines wherever vegetation management is needed and wildfire risk is highest.
“There are 50 million acres that the U.S. Forest Service has said need treatment every year and that’s just forest land,” said Lakhina. In the U.S. there are 237 million acres that need treatment overall. And grazing can cost $1,000 an acre.”
Childrens’ health is at stake along with property and healthy forests, Lakhina added. According to the Harvard School of Public Health, wildfire smoke can be more toxic than air pollution from other sources, leading to more emergency room visits, especially for children who are exposed.
Because BurnBot offers greater precision than grazing, herbicides and mechanical removal, its systems should prove ecologically more beneficial as well, Haddad said. The BurnBot RX is able to help prevent the spread of seeds from invasive species, for example, without causing any of those species to develop resistance to an herbicide.
ReGen was joined in BurnBot’s funding round by investors including AmFam Ventures, which is the venture arm of an insurance company, Toyota Ventures, and earlier backers including robotics fund Pathbreaker, Convective Capital and Chris Sacca’s Lowercarbon Capital.

Boaz Weinstein, the hedge fund investor on the winning side of JPMorgan Chase’s $6.2 billion, “London Whale” trading loss in 2011, is now taking on index fund giant BlackRock.
On Friday, Weinstein‘s Saba Capital detailed in a presentation seen by CNBC its plans to push for change at 10 closed-end BlackRock funds that trade at a significant discount to the value of their underlying assets compared to their peers. Saba says the underperformance is a direct result of BlackRock’s management.
The hedge fund wants board control at three BlackRock funds and a minority slate at seven others. It also seeks to oust BlackRock as the manager of six of those ten funds.
“In the last three years, nine of the ten funds that we’re even talking about have lost money for investors,” Weinstein said on CNBC’s “Squawk Box” earlier this week.
At the heart of Saba’s “Hey BlackRock” campaign is an argument around governance. Saba says in its presentation that BlackRock runs those closed-end funds the “exact opposite” way it expects companies to run themselves.
BlackRock “is talking out of both sides of its mouth” by doing this, Saba says. That’s cost retail investors $1.4 billion in discounts, by Saba’s math, on top of the management fees it charges.
BlackRock, Saba says in the deck, “considers itself a leader in governance, but is crushing shareholder rights.” At certain BlackRock funds, for example, if an investor doesn’t submit their vote in a shareholder meeting, their shares will automatically go to support BlackRock. Saba is suing to change that.
A BlackRock spokesperson called that assertion “very misleading” and said those funds “simply require that most shareholders vote affirmatively in favor.”
The index fund manager’s rebuttal, “Defend Your Fund,” describes Saba as an activist hedge fund seeking to “enrich itself.”
The problem and the solution
Closed-end funds have a finite number of shares. Investors who want to sell their positions have to find an interested buyer, which means they may not be able to sell at a price that reflects the value of a fund’s holdings.
In open-ended funds, by contrast, an investor can redeem its shares with the manager in exchange for cash. That’s how many index funds are structured, like those that track the S&P 500.
Saba says it has a solution. BlackRock should buy back shares from investors at the price they’re worth, not where they currently trade.
“Investors who want to come out come out, and those who want to stay will stay for a hundred years, if they want,” Weinstein told CNBC earlier this week.
Weinstein, who founded Saba in 2009, made a fortune two years later, when he noticed that a relatively obscure credit derivatives index was behaving abnormally. Saba began buying up the underlying derivatives that, unbeknownst to him, were being sold by JPMorgan’s Bruno Iksil. For a time, Saba took tremendous losses on the position, until Iksil’s bet turned sour on him, costing JPMorgan billions and netting Saba huge profits.
Saba said in its investor deck that the changes at BlackRock could take the form of a tender offer or a restructuring. The presentation noted that BlackRock previously cast its shares in support of a tender at another closed-end fund where an activist was pushing for similar change.
At the worst-performing funds relative to their peer group, Saba is seeking shareholder approval to fire the manager. In total, BlackRock wants new management at six funds, including the BlackRock California Municipal Income Trust (BFZ), the BlackRock Innovation and Growth Term Trust (BIGZ) and the BlackRock Health Sciences Term Trust (BMEZ).
“BlackRock is failing as a manager by delivering subpar performance compared to relevant benchmarks and worst-in-class corporate governance,” the deck says.
If Saba were to win shareholder approval to fire BlackRock as manager at the six funds, the newly constituted boards would then run a review process over at least six months. Saba says that in addition to offering liquidity to investors, its board nominees would push for reduced fees and for other unspecified governance fixes.
A BlackRock spokesperson told CNBC that the firm has historically taken steps to improve returns at closed-end funds when necessary.
“BlackRock’s closed-end funds welcome constructive engagement with thoughtful shareholders who act in good faith with the shared goal of enhancing long-term value for all,” the spokesperson said.
Weinstein said Saba has run similar campaigns at roughly 60 closed-end funds in the past decade but has only taken over a fund’s management twice. The hedge fund sued BlackRock last year to remove that so-called “vote-stripping provision” at certain funds and filed another lawsuit earlier this year.
BlackRock has pitched shareholders via mailings and advertisements. “Your dependable, income-paying investment,” BlackRock has told investors, is under threat from Saba.
Saba plans to host a webinar for shareholders on Monday but says BlackRock has refused to provide the shareholder list for several of the funds. The BlackRock spokesperson said that it has “always acted in accordance with all applicable laws” when providing shareholder information, and that it “never blocked Saba’s access to shareholders.”
“What we want is for shareholders, which we are the largest of but not in any way the majority, to make that $1.4 billion, which can be done at the press of a button,” Weinstein told CNBC earlier this week.
