Please provide references for your conclusion - links to websites or your own detailed analysis using math and science. I doubt anyone here is interested in hearing your opinion. When I hear the word "NEVER" in the context you have used. I usually consider that evidence of a closed mind.Leaf wrote:Jeff did that study, got the T-shirt few months ago. Was hopeful for about 5 minutes then I used one of my brain cells......Like I said very small scale "maybe"......I will say this one time. WILL NEVER GIVE ENERGY to 6 billion people or even 6 million for that fact.

When you start a conversation with “stick that in your pipe”, do you really expect a respectful reply? Or are you just looking for a shouting match?Pull in your horns.
Leaf wrote: giving 6 billion people energy. I read those web site you posted months ago. I was hopeful. And if the world had maybe 200 million people and the grond work was already in place for geothermal I would be more hopeful. The ground work is hardly in place and we have 6+ billion people.

Wind has potential to provide up to 40% of the worlds electricity needs.
I like wind. But 40%....Jay how much is in place now? Like .01% worldwide. I like the word potential. Why not say potential of 90%....yeah and maybe bush will tell you its so.

One has to keep in mind that 99% of the earth mass is hotter than 1'000°C and less than 1% is cooler than 100°C.
The terminology "Hot Dry Rock" has evolved since formation fluids have been frequently found from deep boreholes drilled in crystalline rocks. Indeed, between fully hydrothermal reservoirs and totally impermeable hot rocks, there is a complete series of low- to medium-permeability rocks which cannot be exploited for geothermal energy production without specific engineering enhancements.
Names like Hot Wet Rock (HWR) or Engineered Geothermal Systems can be found in the literature. The Swiss project is called Deep Heat Mining (DHM) and recently the US Department of Energy renamed its new Hot Dry Rock programme into Enhanced Geothermal Systems (EGS).
Building a Deep Heat Mining plant will not require the development of essentially new technologies. For decades, electric power has been generated economically from geothermal fields all over the world. The deep drilling technology (5-6 km) into hot and hard rock is available, representing a combination of experiences gained in the oil and mining industries, with specific high temperature tools and knowhow from geothermal industry.

HDR geothermal energy relies on existing technologies and engineering processes, and is the only known source of renewable energy with a capacity to carry large base loads.
On the basis of renewable energy incentives established in Australia, HDR geothermal energy is considered to be competitive with wind and hydro power generated energy. The cost of electricity generated by HDR geothermal power plants is independent of future fossil fuel costs. HDR geothermal energy has the added advantage of being available 24 hours a day and has the capacity to "load follow".
Fossil Fuel Alternatives: The expansion of the nuclear power industry appears to be socially unacceptable. Solar and wind power cannot replace fossil fuels, just augment them and they are limited in scope, intermittent, and unreliable. Large-scale hydroelectric projects are now rejected on environmental grounds. Hot dry rock has the potential, worldwide, to significantly reduce our dependence on fossil fuels.
