Electric Dreams

摘要

The history of alternative transpor-tation fuels is a history of failure. It is a story of one fuel du jour after another-a frustrating cycle of media and political hype followed by disillu-sionment and abandonment. The cycle is all too familiar, from synmels in the late 1970s to methanol in the '80s, and then electric vehicles, hydrogen, and ethanol. A new wave of electric vehicles are now at risk of entering the cycle again.
