Rolling Stone says ethanol is just a subsidy program for agribusiness, that it won't help global warming, and that it will make people starve.

I have, of course, talked about ethanol and other biofuels before.

Technology Review is running a list of young innovators. My favorites are Christina Galitsky, designing efficient stoves and water filtering methods; Utkan Demirci, diagnosing HIV/AIDS cheaply; and Michael Raab, making the ethanol manufacturing process more efficient.
