The cover story of this week's Time Magazine blows the lid on biofuels. Turns out all the corn that is now being grown for biofuels is driving up food prices - cereal is up 20% - and actually making global warming worse.
One factoid: a person can eat for a year on the same amount of corn used to make a tank of gas for an SUV. Yikes. Switchgrass isn't much better but it seems Government subsidies and VC dollars are ignoring the fact. Crazy!
