  •  Fast breeder reactors are the answer... (3+ / 0-)

    Breeder reactors could in principle extract almost all of the energy contained in uranium or thorium.

    This would decrease fuel requirements by nearly two orders of magnitude compared to traditional light water reactors, which extract less than 1% of the energy.

    The thorium in our spent coal ash could power the planet for thousands of years.

    With seawater uranium extraction, there is enough fuel for breeder reactors to satisfy our energy needs for as long as the  sun and Earth relationship persists, about 5 billion years.

    •  I gave you a rec on this... (0+ / 0-)

      ...not because I agree with your ideas, but because I agree with your presentation.  You are, as they say, collegial and polite.  

      But I must level with you, and I don't say this for me personally.  At 79, I've lived my life, and although one never wishes to die, that would be okay.  So when I say that fast breeder reactors really scare me; I'm not saying it in regard to my own personal life.

      Again:  Fast Breeder Reactors really scare me.  I won't pretend to know much about them.  But since we are having so much trouble even managing BWRs with safety (you'll probably disagree with that); nevertheless I would not feel comfortable with humans at our stage of development attempting to safely manage these much more volatile breeders -- as they breed PU.

      The Monju fast breeder in Japan, after having 2 major accidents,  has only been on line to generate energy for 1 hour during it's 20 year existence.  Have you seen this film of their FAILED fast breeder Monju?

      Monju (もんじゅ?) is a Japanese sodium-cooled fast reactor, located in Tsuruga, Fukui Prefecture. Construction started in 1986 and the reactor achieved criticality for the first time in April 1994... MOX-fueled, loop-type reactor...
      “An accident in December 1995, in which a sodium leak caused a major fire, forced a shutdown. A subsequent scandal involving a cover-up of the scope of the accident delayed its restart until May 6, 2010, with renewed criticality reached on May 8, 2010.[1] In August 2010 another accident, involving dropped machinery, shut down the reactor again. As of June 2011, the reactor has only generated electricity for one hour since its first testing two decades prior.[2]…

      I do not believe humankind is yet sufficiently evolved to be able to handle this kind of energy.  Our morality and our greed must change first.
