I know we all hate cancer, but really, free energy is much more important than curing cancer.

Not that this is free energy or anything.

HotWingAgenda: If you already have a source of pure hydrogen, you have fuel. This sounds like using a gas generator to run a windmill.

If you have hydrogen you have a fuel with very low energy density and which does not work with the current transportation infrastructure.  Converting it into methanol solves a couple problems if you can do it in a cost effective way.

StopLurkListen: You can create a fuel out of CO2 , but you're putting more energy into it than you're getting out of it.

2 CO2 + 4 H2O  + energy →   2 CH3OH + 3 O2

P.S. Which is fine in situations you want to store power. For example, batteries. You could think of this as a battery of sorts. It's just not a source of energy itself.

Unlikely?  You mean as unlikely as taking CO2 from the air and converting it to glucose?
