Enhanced Geothermal News

Enhanced geothermal power uses drilling technology to punch two or more holes down into the "hot dry rock" layer of the Earth's crust. Water is then pumped into one hole and steam is extracted from the other hole(s), to drive a turbine generator for electric power. Enhanced geothermal is being pursued in Israel by Ormat Technologies.
Executives at Google have been clear that so-called enhanced geothermal is on the list of technologies they see as cost effective, compared with fossil fuel energy.

The idea behind enhanced, or engineered, geothermal systems is to inject water underground to enhance the permeability of rock, allowing for the release and capture of more heat.

Ormat is working on an enhanced geothermal project organized by the U.S. Department of Energy, which says that these advanced techniques can dramatically increase geothermal potential--by 40 times. __Cnet_via_NextBigFuture
The US DOE believes enhanced geothermal to have the potential to generate thousands of times the energy and power used by humans over the entire planet.

Humans have access to three virtually unlimited sources of energy that can supply their energy needs thousands of times over into the indefinite future. Solar--which needs better storage. Geothermal--which needs technology development. Nuclear fusion--which needs technology development. Biomass could easily supply all of humanities energy needs given more development--but probably not thousands of times over.

We are living in and near an abundance of energy. If you want to play out adolescent fantasies of living in a post-apocalyptic world instead of working to solve problems, go to the peak oil sites. You will find your soul mates there.
