This was similar to the system Eaton makes that will be on all UPS delivery vehicles built in the next few years. Fuel economy savings were estimated at around 20-40% if I remember correctly. I don't know if that project is still active. The Army is also looking at fuel cell vehicles - the electric power they produce would be handy in the field. But that's a lot farther out....
