nuclear is definitely in the near future. engineers have made huge strides in making nuclear power plants better, safer.
but once there is loads of cheap electricity, while gasoline gets even more expensove, you can say good by to the old aged internal combustion motor. we'll all be driving silent (boring) electric cars, which we probably won,t be controlling anyway.
biodiesel will never make it on a large scale, better and cleaner diesel is a better bet.
