Cold fusion has bombed, sonoluminescence seems to be a possibility, Tokamak reactors rarely get more energy out, but now we're trying something different.

Fusion Power?

So the past few years, being a scientific type, I have been fascinated by our attempts to achieve fusion. Unlike fission which we have already mastered, fusion seems to elude us, or rather, sustainable “energy-out” fusion seems to elude us. Cold fusion has bombed, sonoluminescence seems to be a possibility, Tokamak reactors rarely get more energy out, but now we’re trying something different.

The National Ignition Facility will focus 192 lasers on a Deuterium-Tritium pellet to compress it to 1000 grams per cubic centimetre to attain “ignition” (fusion). Fascinating stuff eh? Also, going to cost you an arm and a leg, current costs are at $4-5B, intended to be competed by the mid 2010s (so you can imagine what the costs will overrun to by then).

What are the upsides to fusion? Well for one – no radioactive waste. If it IS self-sustainable, there is very little energy input required apart from the initial “ignition”. The fuel?
