For one, solar energy can only be relied upon during the two-Earth-weeks-long lunar daytime, not the equally long night. 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. How much energy could one really extract from the heat Moon dust gives off via a heat exchanger? 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.
