The article is misleading. Energy is not generated from the air, it uses electricity we already have to make petrol from CO2+water. Then the car burns the petrol to make CO2+water again. No net CO2 is removed from the atmosphere and no energy is gained, it's just that petrol is a convenient high-density fuel for transport (electric cars have expensive and low-capacity batteries).

Finally this isn't revolutionary: http://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_process

What I was going to say... i'd also add... if anything, it increaseses the CO2 in the atmosphere since the electricity likely created CO2 in the first place and the CO2 caused to create the eneregy is going to be greater then what would be pulled from the atmosphere in mostcases...

Plus if anything electricity to petrol convesion has to be less then 100% then you've got lost electricity from the power plant through the cables coming to your gas maker.

 

It's nearly the same reason why Ethanol is a giant waste of time.

Combine this with the fact that the efficiency of petrol engines is laughable (25-30% and can't be improved too much) and you have the reason why this isn't a good idea.
