2nd In my series of 'future energy fail':
The Dymaxion car was a concept car from 1933, designed by U.S. inventor and architect Buckminster Fuller. The word Dymaxion is a brand name that Fuller gave to several of his inventions, to emphasize that he considered them part of a more far-reaching project to improve humanity's living conditions. The car had a fuel efficiency of 30 miles per US gallon. It could transport 11 passengers. While Fuller claimed it could reach speeds of 120 miles per hour.
