Dear all,
In 1978, hydrogen powered engines were in fashion. The famous CBC channel has a very interesting program Market Place where they were showing innovations soon to become products on the market place. One of them was hydrogen powered cars and airplanes.
At that time, in response to some media programs, my friend professor April sent that very interesting letter:
http://docs.google.com/gview?a=v&pid=gmail&attid=0.1&thid=12345727b91c30b2&mt=application%2Fpdf&pli=1
Have we evolved much from then ?
I would not like to see cars going around with high pressure tanks ful, of hydrogen gas since they would be incredible bombs especially with people being not ethical enough to maintain properly their vehicles and this is more a problem in poorer countries.
I would prefere the use of hydrogen gas into aircrafts since people respect the strict regulations much mroe closely. Like this Tupolev project :
The question would then be how much energy can we store in the wings since hydrogen as a very small density.

Some people advocate the application of gellyfied hydrogen in so called fuel cells, since it would not leak into the atmsophere. Here is Boeing's project:
