Move to Ethanol: Worth the Costs?

In my opinion ethanol is just a short-term half-ed solution which will do more bad then good. What ever happened to hydrogen powered vehicles? Hydrogen is one of the most abundant elements on this planet. Oh what.......that's right because it's so abundant it wouldn't be very profitable compared to oil. Why would oil companies "want" or "permit" another industry to make them obsolete as a fuel source? Duh!
