Quaise, Inc is developing a millimeter-wave drilling system for converting existing power stations to use superdeep geothermal energy. The system would repurpose existing gyrotron technology to drill 20 kilometers beneath the surface, where temperatures exceed 400 °C. No fracking would be required, avoiding the potential for earthquakes that have occurred in other geothermal systems. Drilling using this technique is hoped to be fast, with boreholes aimed to be completed in 100 days using existing 1MW gyrotrons. To reduce costs and delays, the company planned to establish its wells on the sites
