Op-Ed: It's crazy to think that American farms can supply enough corn biofuel to make any substantial dent into the energy crisis, columnist John Wasik says.

They will concentrate their risk when prices are at a peak -- and then get burned... Ethanol is also a sorry stopgap," Wasik said. (Here's a similar argument from a nuclear energy advocate.)
