Making Liquid Fuels From Sun And Air

GregLaden writes: There is promising research on converting atmospheric CO2 and water, using sunlight as a source of energy, into burnable liquid fuels.

This is not a carbon capture technique because the CO2 ultimately returns to the atmosphere after burning the fuel, but it could allow the production of enough liquid fuel to allow the rest of the motorized economy to switch to mainly electric.

There are key uses for liquid fuels, even if most "engines" become electric motors.

The science of how this works is fairly interesting, and a recent writeup in Science gives some of the details.
