  •  So when you say that (0+ / 0-)
    the decay of potassium-40 in the Earth's oceans represents 1.3 billion megawatts, which is roughly the power output of 4,400 nuclear power plants of average size

    you neglect the necessary qualifier if you want this analogy to work. Is that 1.3 billion megawatts per year? Are those 4,400 nukes be putting out that much every year?

    IOW, what is your time scale and are these equivalent?

    •  Joieau ! (0+ / 0-)

      Whoops- watts is already per time. Disgusted as  I may be with affectations like "39.9639987 grams" I think NN got his dimensions right. We all get these brain farts at times.

      •  You don't get real time watts (0+ / 0-)

        (work) from radioactive decay, and Nadir has in no way established that 1.3 billion megawatts of real time decay of potassium in the oceans is occurring every fraction of every second of every minute of every day.

        But hey. If we've got billions of megawatts being generated all around us all the time, what the hell do we need nukes for? We could just plug in to the ocean - water's an excellent conductor, and it's already salt-cooled!

    •  The difference between power and energy is one (1+ / 0-)

      of the most telling sources of confusion among anti-nukes.

      Basically it tells one all one needs to know about them.

      Many of them know very, very, very, very, very little about physics, and thus make statements about "watts" in connection with wind and solar plants, where they are actually referring to "peak watts" and not continuous average power.

      Most nuclear plants in this country operate at close to 90% of capacity utilization, and thus peak power is very close to average continuous power.    

      A solar plant that reaches 1000 watts for two minutes is not the equivalent of any other kind of power plant that operates continuously.

      The capacity utilization of solar plants is very lucky to reach 15%.     I reported here the online figures for an American solar facility at the Museum of Contemporary Art in Massachusetts and showed that it was 10%

      The unit I used in referring to power from nuclear plants, and implied average power and not peak power.

      In the case of potassium, it is continuous power, since it is not possible to cause potassium-40's decay to stop.

      •  Oh, the punch line (0+ / 0-)

        is the sig line.

        Check it out. Joy is trying to sell a book that she co-authored, which was published through an author-mill, on ... (wait for it) ... health physics.

        Now, I've seen everything.

        •  Busey? (1+ / 0-)

          I haven't had the occassion to encounter any of her stupidity in recent years.

          It's just as well, since she's such a twit that she makes my blood boil.

          Is she still rototilling national forests to make yuppie McMansions where she can feel all "natural?"

          I'm sure any book from her involving physics would read like a treatise from Pat Robertson on the origin of life.

          These people, Wasserman, Busey and the rest are quite simply the intellectual equivalents of creationists, except that creationists don't actually cause as many deaths as they do.

          •  Yeah (0+ / 0-)

            Apparently, she got banned, but they eventually let her back in.

            I guess every village needs its idiot.

            •  Really? Here? (0+ / 0-)

              They banned her?

              That is surprising.

              •  Well... (0+ / 0-)

                That's what the profile says. I don't claim to understand how these things work.
