Hey guys. Did you happen to catch A Current Affair's highlight of Geothermal energy and specifically the company Petratherm (PTR)? I'm considering adding this one to my portfolio during the new financial year. I'm sure the carbon tax is likely to increase interest in other avenues of energy production. She'll be a sleeper stock by the sounds of it. In case you missed the article, hot areas of Earth's crust (hot rocks) are drilled and replaced with a reservoir of water. The water boils, steam rising to to the surface to heat gas piping that drives the power-generating turbine. What are your views, chaps?
