Ed,
I found the National Geographic program very interesting, primarily because  
they were discussing the direction that General Motors had taken in the design 
 of their new Hydrogen powered platform. It can accept several different body 
 styles.
I also found it interesting because prior to selling my company, Current  
Technologies, we did some wire harness's for GM which were going to be used on  
the Hydrogen platform. There is obviously a huge difference in opinion as to  
what will work and what won't. I guess we will just have to see how it all  
washes out.
Anything that would improve the air quality of the planet without depleting  
natural resources is what we are all looking for.
