Roger,
At last years Detroit auto show, GM unveiled it's new vehicle platform which 
is hydrogen based. The platform includes steering and propulsion and is 
approximately 8 inches high the entire length. The body is fitted to the platform 
and all connections, including joy stick steering are made through one 
electrical connection. When presented at the show, the oil industry spokes people said 
they weren't interested, but GM is going full speed forward with this project. 
This is no longer conceptual, it is already here. They put safety first and 
hired some of the best people available for this project. I read an extensive 
article a while back in one of the International trade magazines I get.....very 
cool project.
The cost for the new vehicle is reported to be somewhere around a mid size 
luxury car, say around $20,000 fully equipped. Bodies can be changed easily in a 
home garage. Mom can have a station wagon during the week and the kids can 
have a sports car on the weekends.
The byproduct of burning hydrogen is water. Water is the only emission.
