We develop Next-Gen technology for harnessing Earth' hard rock heat from 3-7 km depth, where the rock is ~350°C. The earth heat is absorbed by multiple closed loop “heat harvesters” to generate an electric power and utilize a residual heat at the surface. Our GeoHeat Power Technology is capable to produce energy that is clean (no emissions, no wastes, no fuel, no water use), green, climate-friendly, affordable, and available 24/7 anywhere.
