Generating electricity on the Moon comes with inherent challenges.
For one, solar energy can only be relied upon during the two-Earth-weeks-long lunar daytime, not the equally long night. A separate idea being explored is using nuclear reactors to generate power, which comes with its own engineering challenges, given the extreme conditions — cooling such a power station, for instance, given the absence of an atmosphere.
Now, Amazon cofounder Jeff Bezos’ Blue Origin claims to have come up with an entirely different solution with the help of a small startup called Istari Digital — and a heaping dose of AI, of course.
The space firm recently showed off a device at the Amazon Web Services re:Invent 2025 conference in Las Vegas called TEAREX, or Thermal Energy Advanced Regolith Extraction. The company claims it could one day allow future space travelers to survive 14 days of freezing temperatures during lunar night by extracting the heat stored in lunar dust during the day using battery-like tech.
“The TEAREX takes lunar regolith or Moon dust from the surface of the Moon, circulates it through this chamber, and then extracting the heat through a lightweight heat exchanger,” explained Blue Origin enterprise tech VP William Brennan during the event, while holding up a sleek, roughly 12-inch device. “And then, runs it through this cylinder to save the rest of the machine from the sensitive and abrasive rocks.”
“This heat cycle is then reversed during the lunar day to recharge regolith for use during the next night, turning Moon dust into a battery,” he added.
It’s certainly a nifty idea — if it indeed works as promised. But instead of exploring the product’s feasibility or elaborating on how it actually works, the company wasted no time in boasting how the device was designed by an AI. A quick glance at an accompanying Amazon press release barely mentions TEAREX, and instead brags about how its agentic AI models “accelerate lunar hardware development by 75 percent while democratizing innovation across 70 percent of workforce.”
Brennan claimed that an in-house AI agent “helped us with the detailed requirements,” while “another agent helped us create the system architecture.”
“TEAREX is a great example of what we see as a future of engineering teams at Blue,” he concluded during his presentation. “Small teams of experts working with large teams of AI agents to deliver wokrs fo tens and at orders of magnitude faster than before.”
Istari Digital CEO Will Roper, once the assistant secretary of the Air Force during Donald Trump’s first term, also appeared to be largely disinterested in exploring how or if the battery actually worked, telling CNBC in an interview that the real breakthrough was the way his company handled hallucinations by building a “fence around the playground” for its AI.
The small startup’s AI agents run on Amazon Web Services servers, of course, completing an intricate web of Bezos’ personal business interests.
“Within that playground, AI can generate to its heart’s content,” he said. “In the case of Blue Origin’s moon battery, [it] doesn’t tell you the design was a good one, but it tells us that all of the requirements were met, the standards were met, things like that that you got to check before you go operational.”
Which leaves the glaring question: Does it actually work, or is TEAREX a figment of the imagination of several AI agents run wild? How much energy could one really extract from the heat Moon dust gives off via a heat exchanger? We have yet to see the product in action, let alone a working prototype, technical specifications, or a white paper.
Make no mistake, a device that can magically extract energy from Sun-baked Moon dust sounds like an exciting alternative to solar panels and nuclear power generators for future space travelers looking to survive a long lunar night. But given the companies’ focus on AI agents, we have a nagging feeling that TEAREX is more hot air — or regolith — designed primarily to justify Amazon’s enormous AI spending.
