Rodatherm’s $38M Bid to Heat Earth Without Global Drama

Rodatherm Energy just popped out of stealth mode like a tech startup at a comedy roast, clutching a juicy $38 million Series A check to build a closed-loop geothermal plant. That’s right—they're using refrigerants (because who said your AC tech can't moonlight as a planet-heater?) to deliver Earth’s warmth right to the surface. No drilling drama mentioned, just a chill plan to bring heat upward. The reveal was so low key it might as well be underground, fitting for a geothermal company trying to move hot stuff without any messy leaks. Investors must have felt the heat, or maybe it was just the refrigerants doing their job.
