I cannot find any more references to the diesel. Im a little dissapointed. Its put in there kind of as a hindsight or an attention grabber.

Lets think big, think long term. If we could generate enough power to charge one of these for every american family. It would seriously decrease our carbon emissions and severe oil addiction. With the gradual decline of oil and the international increase in demand we need something new.
They claim 50 mpg once the 40 mile charge is used. I also recall reading that a charge could be very cheap. Like a buck or a buck fifty for the first 40 miles. The only bummer is the sticker price is a little on the ouch side.
