Is it economically feasible to create steam powered semi trucks?
Is it possible to create steam powered semi trucks for applications where power is more important than speed? I think that with all our knowledge of steam technology and materials it should be given serious thought especially in light of current problems with fossil fuels. If the fuel of choice were to be, let's say hydrogen, then short range "trains" should be possible.
I found this image over at deviantart.com and think it would be a good starting point: http://browse.deviantart.com/?q=gunslinger87#/d2mfjvk
