"just like passenger rail and hybrid cars". That also includes EVs and the Elio. If someone pays just a little bit more ($180 Million) we may get our Elio's and EM stands to reap the huge profits from government incentives as a result. They wouldn't have to make a dime on the Elio motorcycle.Yes you have sun , but the cost of building and maintaining it will never be recovered . It can only work if someone else is paying a bit share of the cost. Just like passenger rail and hybrid cars. Someone else has to pay for it.
