Google Goes Geothermal
According to a report today on Platts, Google is to invest $10.15 million in advanced geothermal technology. The idea is to develop techniques that will allow geothermal power to be tapped in places where no immediately available natural source exists:
In so-called Enhanced Geothermal Systems, the conditions needed for geothermal generation of naturally occurring pockets of steam and hot water are replicated by fracturing hot rock, circulating water through the system and using the resulting steam to produce electricity in conventional turbines.
The principal beneficiary will be AltaRock Energy, who have a nice graphic description of their technology here.
