What is the energy cost of driving the process?
- JoeAltmaier 11y agoMore than you get, of course. But you're converting electricity into liquid fuel, which has its uses. Think of it as charging a battery, a process which always uses more that it gives back. But we need batteries.

It usually occurs as a minor component of platinum ores; annual production is about 20 tonnes. You can make urine into fuel with platinum and not create CO2 in the first place. http://www.technocrazed.com/scientists-make-urine-powered-fuel-cells-to-drive-cars http://www.technocrazed.com/scientists-make-urine-powered-fu...
