I’m no scientist, and I’m skeptical, but if Sapphire Energy’s claim to have produced “renewable gasoline” pans out to be all its said to be – as well as being production-feasible – then this could be a partial answer to the ongoing energy crisis. Using a system called Green Crude Production, Sapphire basically take sunlight, carbon dioxide and photosynthetic microorganisms (e.g. algae) and produce synthetic 91 octane. Apparently the end product is chemically identical to normal gasoline.
