Diesel??? Rudolph Diesel??! Are you serious?! He is one of the lot that has put us up with these inefficient stinking hot furnaces that happen to have wheels. Are you aware that around 70% of the potential in diesel fuel is lost in heat (exhaust and radiator)??!. I've always learned that back then (beginning of the 20th century) the first cars were electric cars and everybody expected them to stay and develop further. It was not before the big fires in San Francisco (1906) that the direction of development changed as electric fire engines eventually ran out of power where the ones with internal combustion engines prooved reliable. That was the turning point in the history of carmaking, I'm told. Sad, sad, sad and personally I can't wait till we're all moving around with silent, clean and efficient electric motors. An electric motor in every wheel, even a child can think of that! It should have happened long, long ago and would have happened if fossil fuels had not been so damned cheap. Yeah... cheap..., just look at the price we'll all be facing soon. Rudolph Diesel?? If one man has got us in reverse it's him. Besides: what farmer needs a submarine in his garden?
