Pickens is expecting that oil and gasoline demand will rise, their prices will rise, which will spur further interest in alternative fuels, and then this investment will turn a profit.

As the article points out, the market is currently more interested in ethanol.

They're both interesting investment opportunities, but neither a solution for how to continue business-as-usual.
