Nuclear Fusion

I just attended a lecture on the potential of fusion to meet our global energy needs in the somewhat-distant future. According to applied physicists, at temperatures that exceed 100 million degrees, it may be possible to fuse together sub-atomic particles to produce vast amounts on energy. I don’t quite understand the science behind all of it, but theoretically, fusion technology promises nearly unlimited carbon-free energy. Furthermore, scientists are optimistic that they can produce “green” nuclear energy that produces no radioactive waste and is so safe that there is no need for emergency evacuation plans for areas surrounding the nuclear facilities. As an added bonus, with the type of nuclear fusion they are studying, there is no danger of proliferation of nuclear weapons.

The only problem is that they haven’t quite figured out how to do it yet.

The EU, US, China, Korea, Japan, Russia, and maybe others, have pledged $11 billion to build the International Thermonuclear Experimental Reactor, an experimental plant which will be located in France to make the theory of nuclear fusion a reality. If I remember correctly, they hope to prove that nuclear fusion is viable within the next 10 years and then make it commercially available by 2050.

2050 is still a ways off, but if this thing works the way scientists hope it will and big polluters like the US, China, and the EU take concrete steps to curb global warming in the meantime, maybe mankind isn’t doomed after all.
