Quaise Energy Sets New Record for Millimeter-Wave Drilling in Granite

MIT spinout Quaise Energy has successfully drilled a 100-meter borehole into solid granite using millimeter-wave technology, establishing a new record for this method outside a lab. This innovation, which melts rock into glass, could significantly advance geothermal energy by enabling access to deep, high-temperature rock formations globally. The company plans further field tests to tap into heat miles beneath the surface.
