Google said Monday that it will purchase power from small modular reactor developer Kairos Power, as tech companies increasingly turn to nuclear power as a way to fulfill the growing energy demands from data centers.
The tech giant said it will purchase power from a fleet of SMRs made by Kairos Power. Google said purchasing from multiple SMRs sends an “important demand signal to the market,” while making a long-term investment to accelerate commercialization.
“We believe that nuclear energy has a critical role to play in supporting our clean growth and helping to deliver on the progress of AI,” Michael Terrell, senior director for energy and climate at Google, said on a call with reporters. “The grid needs these kinds of clean, reliable sources of energy that can support the build out of these technologies. … We feel like nuclear can play an important role in helping to meet our demand, and helping meet our demand cleanly, in a way that’s more around the clock.”
The company did not disclose the financial terms of the deal.
There are only three SMRs that are operating in the world, and none in the U.S. The hope is that SMRs are a more cost-effective way to scale up nuclear power. In the past, large, commercial-scale nuclear reactor projects have run over budget and behind schedule, and many hope SMRs won’t suffer that same fate. But it is uncharted territory to some extent.
Kairos Power, which is backed by the Department of Energy, was founded in 2016. In July, the company began construction on its Hermes Low-Power Demonstration Reactor in Oak Ridge, Tennessee. Rather than use water as the reactor coolant – as is used in traditional nuclear reactors – Kairos Power uses molten fluoride salt.
Monday’s announcement is another example of the growing partnership between tech companies and nuclear power. Data centers need 24/7 reliable power, and right now nuclear is the only source of emissions-free baseload power. Many hyperscalers have ambitious emissions-reduction targets, which is why they’re turning to nuclear power.
Earlier this year, Google said its emissions have grown nearly 50% relative to 2019 thanks in part to an increase in data center power consumption.
“It is an incredibly promising bet, and one that, you know, if we can get these projects to scale and then scale globally, will deliver enormous benefits to communities and power grids around the world,” Terrell added.
Tesla has reportedly yet to start testing its robotaxi service in Austin without a safety driver behind the wheel – just weeks before the planned launch.
For months now, Tesla and CEO Elon Musk have been hyping the launch of “Tesla Robotaxi”, a Uber-like ride-hailing service powered by autonomous Tesla vehicles, starting with a launch in Austin, Texas in June.
Instead, Tesla plans to build an internal fleet of “10-20” Model Ys and have them offer ride-hailing services in a geo-fenced area around Austin, Texas, helped by human teleoperations. This is very similar to what Waymo has been offering in other cities for years, specifically in Austin, for months now.

Even with the significant downgrade in self-driving capabilities promised with this project, there are many doubts about Tesla’s ability to achieve the lesser goal.
That’s because the robotaxi service will be based on Tesla’s ‘Supervised Full Self-Driving’ program, which is currently achieving about 500 miles between critical disengagements fleet-wide, according to the latest crowdsourced data.
Tesla will be able to improve on that by optimizing a version for the geo-fenced area in Austin and it has been training its neural nets for that for months with vehicles going around Austin.
However, a new report now claims that Tesla has yet to start testing its service without safety drivers at the wheel – similar to Tesla’s public ‘Supervised FSD’. The Information wrote in a new report:
Elon Musk’s deadline for launching Tesla’s first robotaxi service, in Austin, Texas, is weeks away, but the company hadn’t started testing its cars without a human safety driver as of last month, according to an engineer close to the testing and a former employee. That’s a crucial step required before Tesla can launch the pilot service for customers.
For comparison, before launching its paid ride service in Austin, Waymo tested its vehicles with safety drivers in the area for 6 months and then without safety drivers for another 6 months.
Waymo has now taken over a significant market share of ride-hailing rides in the Texas capital, but it still has limitations; for example, it doesn’t drive on the interstate.
The report also mentions that Tesla has been working with local emergency services in Austin to develop intervention plans in order to avoid causing issues if its autonomous vehicles fail.
Electrek’s Take
This is the biggest softball goal. It’s a fraction of what was promised, it’s something that others have achieved before. It’s a punt created for Tesla to finally get a “win” in self-driving.
If they can’t even make it, it would be disastrous, but at least, I hope that it will finally open the eyes of many Tesla shareholders to the reality that Tesla is actually behind in autonomous driving and that Musk’s latest claims that Tesla will have “millions of robotaxi on the road” in 2026 are just the same as when he claimed it would happen in 2025, 2024, 2023, 2022, 2021, 2020, and 2019: corporate puffery.
My main concern now is for public safety. I have little hope of US regulators being able to stop Tesla considering Trump is firing anyone who got in Musk’s way after he gave him over $250 million.
If Tesla brings its cowboy approach to this, it could get bad quickly.

The development of Rivian’s R2 validation builds continues to progress. We know so because the American automaker’s founder and CEO, RJ Scaringe, continues to pepper us with welcome updates with plenty of fantastic images. The latest post features the inner workings of Rivian’s Maximus drive unit, which will propel the upcoming R2 EVs when they hit the market next year.
Another day, another exciting social media update from RJ Scaringe. Nine days ago, the Rivian CEO shared a peek at the company’s new Maximus drive unit, designed to be more compact and efficiently built to help reduce cost-per-unit production.
Our only look was from outside the drive unit’s casing at the time, but it was exciting news nonetheless. As an encore, Scaringe posted photos of the R2 validation builds on a pilot line at the automaker’s facility in Normal, Illinois.
This evening, Scaringe took to Instagram and X once again to share a better look at the inner workings of the Rivian Maximus drive unit. Check it out:

RJ shares more images of Rivian’s Maximus development
Rivian’s CEO posted the three images above, which showcase some interesting perspectives of the developing drive unit. As previously shared by Rivian, Maximus uses a new continuous winding technique that reduces the total welds per stator and thus the total overall cost of building each one.
For comparison, Rivian’s current Enduro drive unit requires 264 stator welds, while Maximus only needs 24. You can see the stator windings in the image above to the left. Scaringe shared excitement in the progress of the Rivian team’s Maximus drive unit as well as some insight in his post:
I love the packaging on Maximus — the drive unit for R2. It has a side mounted inverter that utilizes flat area at the end of the motor to minimize the length of bus bars, keeping them light and efficient. The large planar shape also allows all processing and power electronics to exist on a single printed circuit board.
The inverter chassis closes out the oil cooled motor cavity and seamlessly routes coolant from the power modules to the drive unit’s heat exchanger with no extra parts.
Overall, the inverter part count is reduced by 41% relative to Enduro and structural inverter lid saves more parts and fasteners by also serving as the drive unit mount. I love this design efficiency. (heart emoji)
Looks fantastic, RJ. We can’t wait to see the visual progress of the R2 you share next!
