hot dry rock geothermal energy saves the day
Its seems peak oil will be no problem for nations which utilize hot dry rock geothermal energy (hdr). I used to be very afraid about peak oil until I read about hdr. I haven't seen any peak oil site which accounts for the benefits from hdr. (I've spent at least 50 hours researching peak oil.) HDR appears very promising and is near completion in Soultz, France.
Here is a little info about hdr: {uel=http://www.soultz.net/]link[/url]
* One 1 km³ of 200°C hot granite cooled by 20°C...
* ...delivers about 10 MW of electric power...
* ...for a period of 20 years.
Available resource
= 125'000 km² in W.Europe with >200°C at ~5000 m depth (Shell study) link
HDR geothermal energy relies on existing technologies and engineering processes such as drilling and hydraulic fracturing, techniques established by the oil and gas industry. Standard geothermal power stations convert the extracted heat into electricity. link
Hot dry rock resources occur at depths of 5 to 10 miles (8 to 16 kilometers) everywhere beneath the Earth's surface, and at shallower depths in certain areas. Access to these resources involves injecting cold water down one well, circulating it through hot fractured rock, and drawing off the now hot water from another well. This promising technology has been proven feasible, but no commercial applications are in use at this time.
Put this information in your pipe and smoke it! Tell me what you come up with.
