Ok, it's a more efficient way of burning coal. You're still CO2-emmision positive.

  > You're still CO2-emmision positive. And so what? I said that, did you not read what I wrote? I'll quote it for you: "this will greatly reduce CO2 emissions, even though it's not completely zero." > more efficient That is way underestimating it, it's a fraction of the CO2 output of any other fuel. By far most of the energy comes from the sun, only a small amount comes from the coal. And it's pollution free since all the heavy metals in coal are captured at the source. It also fits in well with existing technology since there don't exist any other ways of transporting fuel in bulk except hydrocarbons. There simply doesn't exist any other way of doing it. Have you ever heard the saying "The perfect is the enemy of the good?" Trying to be eliminate CO2 entirely is impossible, if you hold out for that you'll do nothing whatsoever.
