The corn ethanol rip off is kind of ridiculous. I still have hopes though that algae produced ethanol may be cost effective. There's a company called Algenol that's been trying for a while with genetically modified algae and projecting cheaper than oil ethanol next year for quite a few years now but you never know - they may get there one day.
