Quaise Energy is on a mission to prove that deep geothermal drilling could provide more than enough clean energy to meet the world’s needs as we move away from fossil fuels. Matt Houde, cofounder at Quaise Energy, explained its potential at the TEDX Boston Planetary Stewardship Event last week.
The aim of the Boston event, which was timed to run at the same time as COP27 in Egypt, was to “spotlight actionable ideas for human activity to achieve a sustainable relationship with the planet’s natural systems,” according to TEDX Boston’s website.
Deep geothermal’s potential
Houde, a speaker at TEDX Boston, explained why deep geothermal has so much potential:
The total energy content of the heat stored underground exceeds our annual energy demand as a planet by a factor of a billion. So tapping into a fraction of that is more than enough to meet our energy needs for the foreseeable future.
But we can’t yet drill deep enough to unlock that energy. Houde continued:
If we can get to 10 miles down, we can start to find economic temperatures everywhere. And if we go even deeper, we can get to temperatures where water [pumped to the site] becomes supercritical, [a steam-like phase that will allow] a step change improvement in the power production per well and so cheapen the cost of energy.
The deepest hole that’s been drilled to date, the Kola borehole in Russia, is 7.6 miles deep. It took 20 years to complete because conventional equipment like mechanical drill bits break down at those depths.
“And the truth is, we’ll need hundreds if not thousands of Kola boreholes if we want to scale geothermal to the capacity that’s needed,” Houde said. He went on to assert that Quaise:
[I]s developing technology to blast rock with microwaves to potentially drill the deepest holes on Earth. And no, I’m not stealing a plot device from Star Trek. This technology is real and has been proven in [an MIT] lab.
Deep geothermal’s possibility
Houde explained the benefits of deep geothermal energy in general. These include being available 24/7, which “can help balance out the intermittent flows of wind and [solar].” Deep geothermal plants also won’t need much land. Houde illustrated this with an artist’s rendition of a future rig next to truck shipping containers (see main photo).
Houde also said that deep geothermal is “the perfect energy source to take advantage of the largest workforce in the world, the oil and gas industry.” That industry has “11 million jobs in the US alone, and a skill set that is exactly what’s needed for geothermal to rapidly scale.”
Drilling with microwaves
Quaise is working to replace conventional drill bits with millimeter wave energy – cousins to the conventional microwaves we heat up our leftovers with. Those millimeter waves literally melt then vaporize the rock to create ever-deeper holes.
Scientists developed the general technique at MIT over the last 15 years, and proved that millimeter waves could actually drill a hole in basalt. The gyrotron machine that produces the millimeter wave energy has been used for around 70 years in nuclear fusion research.
Quaise’s technique also uses conventional drilling technologies developed by the oil and gas industry. The company will use these to drill down through surface layers – what they were optimized for – to basement rock – which millimeter waves can easily power through.
Houde explained that millimeter waves “are ideal for the hard, hot, crystalline rock deep down that conventional drilling struggles with.” They’re not as efficient in the softer rock closer to the surface, but “those are the same formations that conventional drilling excels at.” That’s why Quaise applies a hybrid approach to the problem.
Challenges remain
There are still several challenges that Quaise has to tackle in order to scale its technology, including a better understanding of rock properties at great depths. Further, Houde said, “we need to advance the supply chain for gyrotrons” and the waveguides that carry their energy downhole. That equipment is currently optimized for specialized one-off projects in fusion research. For deep geothermal applications, they must be produced in quantity and be robust and reliable in a field environment.
There are also engineering challenges that must be addressed. Houde said:
Chief among them is, how do we ensure full removal of the ash [created by the process] and transport that ash up the borehole over long distances?
Progress so far
In the MIT lab, engineers drilled a hole in basalt with a 1:1 aspect ratio – 2 inches deep by 2 inches in diameter. Quaise built upon MIT’s results by scaling up the power density of the microwave beam and the depth of the hole by a factor of 10 to achieve a 10:1 aspect ratio. The company is now building the first field-deployable prototype millimeter-wave drilling rigs.
Houde said:
Our current plan is to drill the first holes in the field in the next few years. And while we continue to advance the technology to drill deeper, we will also explore our first commercial geothermal projects in shallower settings.

This fund most recently provided aid for communities affected by the recent Los Angeles wildfires, assistance to the Special Forces Charitable Trust (SFCT) in North Carolina following severe hurricanes, and support for non-profits engaged in hurricane preparedness in Florida and the Gulf Coast. Per Jodi Burns, CEO of the Special Forces Charitable Trust:
In the wake of devastating storms in Western North Carolina, reliable power was a critical need for the families we serve. Thanks to EcoFlow’s generous donation of generators, we were able to provide immediate relief, ensuring these families and their communities had access to power when they needed it most. We are so impressed with EcoFlow’s commitment to disaster response through their ‘Power for All’ program. It has made a tangible impact, and we are deeply grateful for their support and partnership in helping these families recover and rebuild.

Tesla is losing another top talent: its long-time head of software, David Lau, has reportedly told co-workers that he is exiting the automaker.
Tesla changed how the entire auto industry looks at software.
Before Tesla, it was an afterthought; user interfaces were rudimentary, and you had to go to a dealership to get a software update on your systems.
When Tesla launched the Model S in 2012, it all changed. Your car would get better through software updates like your phone, the large center display was responsive with a UI that actually made sense and was closer to an iPad experience than a car.

Tesla also integrated its software into its retail experience, service, and manufacturing.
David Lau deserves a lot of the credit for that.
He joined Tesla in 2012 as a senior manager of firmware engineering and quickly rose through the ranks. By 2014, he was promoted to director of firmware engineering and system integration, and in 2017, he became Vice President of software.
Lau listed the responsibilities of his team on his LinkedIn:
Vehicle Software:
Firmware for the powertrain, traction/stability control, HV electronics, battery management, and body control systems
UI software and underlying Embedded Linux platforms
Navigation and routing
iOS and Android Mobile apps
Distributed Systems:
Server-side software and infrastructure that provides telemetry, diagnostics, over-the-air updates, and configuration/lifecycle management
Data engineering and analytics platforms that power technical and business insights for an increasingly diverse set of customers across the company
Diagnostic tools and fleet management, Manufacturing and Automation:
Automation controls (PLC, robot)
Server-side manufacturing execution systems that power all of Tesla’s production operations
Product Security and Red Team for software, services, and systems across Tesla
Bloomberg reported today that Lau told his team he is leaving Tesla. The report didn’t include reasons for his stepping down.
Electrek’s Take
Twelve years at any company is a great run. At Tesla, it’s heroic. Congrats, David, on a great run. You undoubtedly had a significant impact on Tesla and software advancements in the broader auto industry.
He is another significant loss for Tesla, which has been losing a lot of top talent following a big wave of layoffs around this time last year.
I wonder who will take over. Michael Rizkalla, senior director of software engineering and vehicle firmware, is one of the most senior software engineers after Lau. He has been at Tesla for 7 years, and Tesla likes to promote within rather than hire outsiders.
There are also a lot of senior software execs working on AI at Tesla. Musk has been favoring them lately and he could fold Lau’s responsibilities under them.

Kia’s electric SUVs are taking over. The EV3 is the best-selling retail EV in the UK this year, giving Kia its strongest sales start since it arrived 34 years ago. And it’s not just in the UK. Kia just had its best first quarter globally since it started selling cars in 1962.
Kia EV3 is the best-selling EV in the UK through March
In March, Kia sold a record nearly 20,000 vehicles in the UK, making it the fourth best-selling brand. It was also the second top-seller of electrified vehicles (EVs, PHEVs, and HEVs), accounting for over 55% of sales.
The EV3 remained the best-selling retail EV in the UK last month. Including the EV6, three-row EV9, and Niro EV, electric vehicles represented 21% of Kia’s UK sales in March.
Kia said the EV3 “started with a bang” in January, darting out as the UK’s most popular EV in retail sales. Through March, Kia’s electric SUV has held on to the crown. With the EV3 rolling out, Kia sold over 7,000 electric cars through March, nearly 50% more than in Q1 2024.

Starting at £33,005 ($42,500), Kia said it’s the “brand’s most affordable EV yet.” It’s available with two battery packs, 58.3 kWh or 81.48 kWh, good for 430 km (270 miles) and 599 km (375 miles) of WLTP range, respectively.

With new EVs on the way, this could be just the start. Kia is launching several new EVs in the UK this year, including the EV4 sedan (and hatchback) and EV5 SUV. It also confirmed that the first PV5 electric vans will be delivered to customers by the end of the year.
Electrek’s Take
Globally, Kia sold a record 772,351 vehicles in the first quarter, its best since it started selling cars in 1962. With the new EV4, the brand’s first electric sedan and hatchback, launching this year, Kia looks to build on its momentum in 2025.
Kia has also made it very clear that it wants to be a global leader in the electric van market with its new Platform Beyond Vehicle (PBV) business, starting with the PV5 later this year.
Earlier today, we learned Kia’s midsize electric SUV, the EV5, is the fourth best-selling EV in Australia through March, outselling every BYD vehicle (at least for now). The EV5 is rolling out to new markets this year, including Canada, the UK, South Korea, and Mexico. However, it will not arrive in the US.
For those in the US, there are still a few Kia EVs to look forward to. Kia is launching the EV4 globally, including in the US, later this year. Although no date has been set, Kia confirmed the EV3 is also coming. It’s expected to arrive in mid-2026.
