Steam building for Enhanced Geothermal Systems

A worthy alternative energy?

Perhaps according to Popsci, which claims that Enhanced Geothermal Systems (EGS) could be 200 times cheaper and much more cost-effective than clean coal. Likewise, it is constant power, unlike solar power which requires sun shine and wind power which requires wind. And, thanks to Google and the Department of Energy, a number of EGS pilot projects are now under way, so we should soon know if geothermal is a legitimate alternative energy.
