Spallation Drilling for Deep Geothermal Wells

Seeker Blog article on geothermal energy suggests that spallation drilling should provide an economic means for drilling at the necessary depths for high quality heat.

Hydrothermal spallation was invented and patented by cofounder Bob Potter and Jefferson Tester of MIT. The patent is owned by MIT and licensed exclusively to Potter Drilling.
