*"Quaise uses a gyrotron, originally developed for fusion research at MIT’s Plasma Science and Fusion Center, to produce millimeter-wave energy that ablates rock by vaporizing it with no mechanical contact. Last year, they drilled through 100+ meters of granite in Central Texas in the first field demonstration of the technology. This year, they’re targeting a kilometer, then eventually, 10-12 miles. At full depth, a single superhot well would produce 5-10x more power than a conventional geothermal well."*
