The Trouble with Clean Coal

Shooting from the hip here, I seem to remember that setting coal seams on fire (to gasify coal underground) should more likely be on the nightmare side of the carbon equation.
If I remember an editorial by the editor of World Oil correctly, coal seams are burning out of control at various locations and have done so for thousands of years. The CO doesn't stay put. It comes up for O. Not a pretty CO2 scenario.
May be advisable not to set light to more underground coal.

Does Wind Power Produce More Carbon Emissions than Coal?

We've been using the figure of four months to generate CO2-free energy equivalent to the manufacturing energy CO2 of a 2.3MW turbine. But I don't have the math to hand. The number came from our city energy company's wind technician.

Rentech: Picked Green

Gasifying coal for liquid fuel should not be considered green. Remember, the synthetic crude so inefficiently obtained then has to be refined. I've seen the CO2 emissions estimated at seven times those of conventional diesel manufacture. When I last looked China was building its first such plants. If they catch on, it would be disastrous. But they won't.
