(6) Abundant Power from Universal Geothermal Energy
Pioneering studies initiated by Prof. Jefferson Tester of MIT.
Geothermal can be much more widespread by making artificial reservoirs to harvest the earth’s heat.
There is need to create porosity and permeability, also good connectivity between a set of injection wells and a set of production wells, with the sweep fluid, water.
New oil field technologies like deep drilling, stimulation/fracturing, multi- laterals etc can be used for deep heat mining.
Prof. Tester calls it “ Universal Geothermal”, energy because reservoir can be located wherever necessary, such as power-hungry cities worldwide.
Current world energy consumption 400 Quads (Quadrillion BTU).
Potential Geothermal Energy 100 million Quads.
If only, 1/10th of 1% comes out, it will be 100,000 Quads (Equiv. to 250 years of current global energy consumption).
Minimal impact on environment.
Further studies however required but seem doable.
