The point in all of this is that nuclear power has LONG been the solution to the energy crisis, but has been held back by fear and environmentalists for too long. Even if projects were approved TODAY, it can take around 10 years to build a facility.
All the talk about electric, compressed air, or hydrogen cars as alternatives to gasoline and diesel fuel vehicles cracks me up... you still need an energy source of SOME TYPE to be stored as electricity, compressed air, or hydrogen! That source as of right now is some 80% coal or some fuel gas! So these things would NOT solve ANYTHING. Nuclear power is, and has always been, the solution. | Based on known reserves of uranium, etc; known nuclear reserves would last around 250 years.
I think most of it would need to be imported as well.

| so when are we going to learn to harness the actual energy released by the atomic process? all we do now is use the heat to create steam.

I'd be interested to see the data that backs up the indication that the uranium available will only last 250 years... | |

I know it is a small reactor...but I thought with it would come less fuel at one time. I guess that's good...but you probably wouldn't want to lose that reactor (read: dirty bomb) since it is capable of being transported. | |

In some ways I don't completely get the remote/rural thing. If the area if fed with power ... couldn't the power just be piped in from a large plant that is farther away? I know distribution isn't easy...but neither is train-carrying in fresh reactors and reactors with spent fuel....
Regardless, increased flexibility is generally a good thing.... | This could be used heavily in the mortheast... where they rely heavily on combustion turbine generation (which is very expensive).
