So I was writing a scene earlier today, based upon the idea of a solar powered still producing ethanol for fuel. By the power of teh internet, I have found that it is possible, and that people have already built there own- Making Alcohol Fuel With a Solar Still – Renewable Energy – MOTHER EARTH NEWS.

A small British company has produced the first “petrol from air” using a revolutionary technology that promises to solve the energy crisis as well as helping to curb global warming by removing carbon dioxide from the atmosphere.
I can’t be the only one who wants to see the numbers before getting too excited. How much energy goes in and how much is produced? Depending upon efficiency etc. it could be a good way of storing energy generated by solar or wind when it’s not immediately needed by the grid.
A company called 2OC is planning to install mini turbines in natural gas pipelines to generate electricity. The gas is at too high a pressure when it comes out of the ground for safe distribution so sites known as letdown stations are used to release the pressure. The turbines would be installed in these stations and could generate as much as one coal or nuclear power station.
2OC admits that this is an expensive way to generate electrity. But it is making use of energy that would otherwise be wasted. The letdown process also has a cooling effect- as the gas expands its temperature drops drastically- and the company are looking at ways to use this such as cooling data centres.
