WAtching this show on PBS HD tonight. Had a show about Global Warming and Global Dimming. They mentioned that if we don't stop burning gas, oil, and coal, the temperature could increase as much as 14 degrees in the next century. Ok, so what else is there? Steam, perhaps. But the ideal solution would be to use the worlds oceans as a fuel source.... How close are they to get us off the monster that is gas these days at $3.00's per gallon?
