The startup uses millimetre-wave microwave beams — technology originating from MIT research — to vaporise rock at depths beyond 5km, reaching temperatures of 300–500°C that conventional drill bits cannot access. The funds will go toward Project Obsidian in Oregon, targeting the world's first commercial superhot geothermal plant with grid power delivery by 2030. A hyperscaler has already signed for the first 50MW of output. The company's test site in Texas has reached nearly 1km depth, still far short of the 5km+ target, leaving the core engineering challenge unproven at commercial scale. The raise reflects surging investor interest in always-on clean power driven by AI data centre demand. ## Full article daily.dev links to this article rather than hosting it.
