re: News: Central Petroleum to present at the... camdenbob, my understanding about geothermal is that it does rely on water, but it is a closed loop. What I mean that after the water turns to steam, and goes through turbines, it cools down, turns to water, and gets cycled back and the process starts again. If there are no leaks, in theory there shouldn't be much if any waste. In not sure what the reality is though
