Is coal to fuel cars too good to be true?

[thewayne]

Interesting article. It currently takes 1,000 megawatts(!) of energy to produce 160 gallons of fuel. A process that's been refined for almost as long as we've been driving cars that converts coal into liquid fuel produces the same amount of gas but requires 350 megawatts.

Great savings, neh?

Neh.

It does nothing to reduce greenhouse gasses and doubles the amount of CO2 being released.

So, lower fuel prices for the cost of more CO2? Doesn't seem too good of a deal. But it could be a good bridging technology to keep cars on the road while other fuel/automobile technologies come to market. I wonder if they could make an improved catalytic converter-like device that could be a move effective CO2 scrubber, but then you get problems with the Sontarans (if you're a Doctor Who follower).
