DELICIOUS DISONNANCE:

This energy source could solve all of our problems -- so why is no one talking about it? (Pascal-Emmanuel Gobry, 3/04/14, The Week)

There's a band of hipsters within the community of people who think hard about energy who think this is a bunch of hoo-ha. We already have a perfectly useful and clean energy source, they say: nuclear power. In terms of its capacity, nuclear power could provide almost all of our energy needs. In terms of carbon emissions, nuclear power is totally clean. Outside of a handful of countries whose names you probably already know, proliferation isn't an issue. Of course, there's the issue of safety. But nuclear power is safe, advocates say. Chernobyl happened because of the insanity of communism, and Fukushima because you probably shouldn't build reactors on the path of tsunamis, not because of anything inherent to nuclear power. The solution to nuclear waste, they say, is more R&D, so that waste can be recycled. Look at France! It draws almost all of its energy from nuclear power, with no serious incident to note in the past 50 years, and the power is cheap, plentiful, and clean.

Within the energy analysis community, nuclear advocates are one hipster subset. But as always when we're talking about hipsters, there's a subset within the subset. And these energy hipsters are pushing a nuclear technology that has all the advantages of traditional nuclear and none of the drawbacks. Its name is thorium.

Thorium is an element, like uranium and plutonium, which you can use as fuel for a nuclear reactor. Unlike uranium and plutonium, thorium is abundant. Unlike uranium and plutonium, thorium reactors could have "passive" safety. Traditional nuclear reactors sometimes have the annoying tendency of sometimes exploding and showering the area around them with radioactive waste. This is because plutonium and uranium reactors, when shut down, cannot cool off on their own. They need "active" systems to cool them down. If these systems fail, the reactor starts going into meltdown. Thorium, being a lighter element, doesn't have that problem. If you have an emergency in a thorium reactor, you shut it off, and it cools down on its own. It can't melt down. Unlike uranium and plutonium, thorium produces minimal amounts of waste, and even the little waste it does produce is potentially recyclable. And finally, unlike uranium and plutonium, with thorium you can make a reactor, but you can't make a bomb.

And there you have the problem.

Thorium advocates point out that almost from the beginning, nuclear research has been sponsored by governments -- or, more accurately, military-industrial complexes.

One of our favorite confusions on the Right is that we should all convert to nuclear energy because it's such an awesome power source but Iran should close its entire nuclear program.
