Frankly I'm mad that something with the potential value of so much energy is being wasted on such trivial uses. If you expose U-238 to a neutron flux it will become Pu-239. This is great fuel for reactors. One kilogram is equivalent to about 22 million kilowatt hours of heat energy.We could be powering up cities and  yet thanks to a bunch of foolish environmentalists this vast energy resource is being wasted.

I agree. In fact, we should be making many new pebble-bed nuclear reactors to replace coal-fired power plants. It would do a lot for air quality and reduce health problems (not to mention helping with greenhouse gases).

Try telling that to the "environmentalists" though... ;-)
