Potential energy leads for future

Excellent summary of what we can foresee now. I fully agree with the long term possibilities that will be at our disposal:
Electricity for cars, trucks, buses and trains
Hydrogen for airplanes and boats?
How about atomic energy for big cruise and transportation boats?
I tought that Hydrogen had all the features necessary to be "the" energy for the future but its dangers and bulky storage make it very difficult to use in cars.
The only issue is that we will have to step up the speed at which we are progressing right now and I am not sure that the car manufacturers are very enthusiastic about this. How about a world financed research?
