In this new world of energy-saving and people crying out for Al Gorian policies, could one imagine the return of the iconic zeppelins from the beginning of the last century. I mean, these babies could be powered by electrical engines, made quite large, and carry a good amount of freight OR passenger, not to mention the relatively easy landing of these giants.
Just imagine a 600m long nuclear-powered zeppelin

Though the Gore-boys wouldn't like that one...
So I ask you, is there any hope for a revival of these beautiful creations?
