Re: E-M:/ Power from Not-So-Hot Geothermal

The article describes how the system makes use of hydrofluorocarbon (HFCs) refrigerants which is vaporized to drive turbines. HFCs are the less destructive substitute for ozone depleting CFCs. However, HFCs are extremely potent greenhouse gases - 1,000 to 10,000 times worse that Carbon Dioxide and their use should not be encouraged. Energy conservation and discouraging increases in demand for energy should be our first task.

See the following article for basic information HFCs

Power from Not-So-Hot Geothermal

This power system could make it feasible to generate
cheap electricity from lukewarm geothermal sources.
