The data is old, I will see if I can find the webpage.  The only advantage that 
hydrogen has is that it produces water vapor.  The energy density is very low as 
compared to any of th other fuels, it takes a lot of energy to liquify (better off using 
the compressed gas).  I am personally in favor of fuel cells, there are a variety of 
fuels that can be used.

>I've never seen the btu ratio you quote used for explaining the expected failure of 
a hydrogen economy. Assuming this is true, it is still a bit misleading as hydrogen 
already works twice as efficiently in a combustion engine as gas, and this is with 
barely any research, comparatively speaking of course, done in hydrogen fuel 
options. I would think that if a little more was spent on research in this field, we 
would most definitely see a great deal more output.
