I would love to see a nuclear powered vehicle. It's not all that unrealistic from a technical point-of-view.

NASA article on radioisotope powered systems
New prototype nuclear battery (states energy density is ~3.3 Wh/gram)

This article indicates modern radioisotopic thermal generators can produce about 12 watts/pound (nothing stated on energy density).

A lithium battery produces about 0.265 Wh/gram, thus the new nickel-diamond based battery (2nd link above) sound really enticing; no idea of cost (on any of this!).

Maybe one day ...

Ken
