Oh Perfect World!
Scientists at UCLA are developing a system of using a modified bacteria, cyanobacterium, to convert CO2 into the liquid fuel isobutanol. Reduce excess CO2 in the atmosphere while generating liquid fuel? Wouldn't it be nice if something like this actually worked with some useful degree of energy efficiency in terms of EROI (Energy Returned On energy Invested)? I hope so.
