- And for those of you who don't know, the reason is that you either
- need a very LARGE vehicle (to isolate the reactor physically) or a
- great deal of shielding, which starts a vicious circle of increasing
- the size and weight -> needing more power -> larger reactor ->
- more radiation -> more shielding -> and so on. Curiously, this
- ends up being much like the first case (a large vehicle), although
- not quite so large. This is why nuclear power has been practical
- for submarines (and surface seagoing vessels, too, although not
- much has been done), since they can be quite large and still be
- useful. As far as land vehicles are concerned, one could
- certainly envision a huge vehicle to traverse deserts and tundra,
- where there are minimal obstacles to avoid and relatively little
- interaction with human settlements, but first there would have
- to be a practical need for such a vehicle.
