geothermal could power the whole world

Proponents say that the potential of deep geothermal as a clean energy source is just tremendous, and cost effective. Trials are underway now to develop the best techniques in order to tap into this significant heat source.

.."A study released this year by the Massachusetts Institute of Technology said if 40 percent of the heat under the United States could be tapped, it would meet demand 56,000 times over. It said an investment of $800 million to $1 billion could produce more than 100 gigawatts of electricity by 2050, equaling the combined output of all 104 nuclear power plants in the U.S."...more, another good "disruptive technology" research field with severe lack of funding, there
