My friend Triticale alerted me to this piece on pebble bed reactors a few days ago and now I see Instapundit has it up as "the answer" to America's energy problems. As a former Naval Reactor Operator I might have a thing or two to say about the radiation and safety questions. As a student of energy systems I might ask how much net energy can be gotten out of such a device net manufacturing and mining energy. Which includes the cost of enriching the uranium. But I'm not going to deal with any of those questions.
Which brings me to my multiple choice test.
Is there enough plutonium in the world?
a. just enough
b. too much
c. more is needed
