Should Google Go Nuclear? 419
Baldrson writes "One of the founders of the US Tokamak fusion program, Dr. Robert W. Bussard, gave a lecture at Google recently now appearing as a Google video titled 'Should Google Go Nuclear?'. In it, he presents his recent breakthrough electrostatic confinement fusion device which, he claims, produced several orders of magnitude higher fusion power than earlier electrostatic confinement devices. According to Bussard, it did so repeatably during several runs until it blew up due to mechanical stress degradation. He's looking for $200M funding, the first million or so of which goes to rebuilding a more robust demonstrator within the first year. He claims the scaling laws are so favorable that the initial full scale reactor would burn boron-11 — the cleanest fusion reaction otherwise unattainable. He has some fairly disturbing things to say in this video, as well as elsewhere, about the US fusion program which he co-founded."

It's pretty much the same with our current fission reactors. There is no way that the design of the reactors would ever blow up like an Atomic warhead, because the warheads are explicitly designed to go super-critical in a very particular fashion, with the intent of burning the maximum amount of fuel possible in the shortest period possible.
There are actually shaped charges on the outside of the weapon to trigger this event. These charges *must* be properly aligned, or the weapon will never reach super-criticality. That's why the heros in the movie The Peacemaker removed one of the charges from the weapon. Without it, the normal explosives would detonate harmlessly. (There is another type of bomb that slams two carefully shaped, barely sub-critical pieces of Uranium together REALLY, REALLY, REALLY hard. Again, you have the same problem of the design having to be precise.)
About all you can get from a fission reactor is the raw materials to make a weapon. And even then, it's best if the reactor is configured to produce the materials you need. It's pretty much the same way with a fusion plant. You can use or produce materials useful in nuclear weapons, but the reactor will be nowhere close to a weapon itself. The key safety issue is thus to ensure that sufficient safeguards exist to prevent the release of any poisonous radioisotopes back into the environment. (If the fusion reaction is completely clean, then this isn't a concern.) We wouldn't want another Chernobyl, which happened mostly because there weren't sufficient safeguards, and the ones that existed had been explicitly disabled (with authorization!) by untrained personnel.
The irony? They wanted to test the reactor to see if it would fail properly without the safeguards installed. Guess they got their answer.

I'd even go so far as to say that cheap energy for all would save the world. I'm not normally a doom and gloom kinda guy, but it seems to me that the path we're headed on right now leads to civilization breaking down.
With cheap and bountiful energy, the US would care a whole lot less about what's happening in places with oil. And in turn those places would care a whole lot less about the US. Many parts of the world could be made to be much more pleasant places to live, and the general cost of getting things done plummets.
Right now there are many, many people in the world who are extraordinarily unhappy with things as they are, and would take down civilization if they could. They lack only the means, not the motive. Eventually, and inevitably, the means will become more and more accessible. Suicide bombers, for instance, are an expensive weapon. They work only once, at most, and are difficult to cultivate. Recently there was a story of Israel wishing to develop a lethal insect-sized robot. While not practical today, sooner or later it will be. And not long after that, cheap enough and available enough to use in place of suicide bombers. At that point the equation changes, and destabilizing society on a larger scale becomes much easier to do.
The only way to save the world is not through force, but rather improving the lives of everyone, everywhere. And nothing would take anywhere near as large a stride towards that end as cheap and plentiful energy for all.
The way to stop terrorism is not by spending a trillion dollars killing people, but rather spending that money on figuring out how to make things better.

For those of you familiar with Hollywood Science, 11 years of research with a load of failed designs may not seem like an investment.

The 'wiffle ball' effect is really cute. He is working with plasmas. You have charged stuff zipping about in magnetic and electrostatic fields. Unfortunately, that stuff is itself charged, and because it is moving, it has its own magnetic field. This usually means the plasma can work out within microseconds what it is not supposed to do, and start hosepiping, or wiggling, or whatever it was that it shouldn't. Just occasionally, you can use this self-will to your advantage. The microwave magnetron is an example (particularly cute that he used one inside his experiment to keep the ionization up). Well, I would see that you could concentrale positive ions using negative electrons, but wouldn't they hit each other and neutralize all the time? Well - no they don't, because the electrons will make fast lanes through the slower moving ions.

I think the electric utilities have settled on using sulfur hexafluoride as the best solution for this issue in high voltage transformers. In spite of the frightening name this gas is actually non-toxic (and if you breathe it you get the opposite of the helium effect because of its high density

Also, oil companies are some of the ones leading the alternative energy charge, believe it or not. Oil companies know even better than you do that their oil wells are not going to last forever, and they want to be ready when they do start drying up by already being leaders in the next power resource. They are generally not stupid nor abnormally immoral. They do want to make a buck, but they are good at thinking long-term.

In this analogy, the oil companies "leading the alternative energy charge" are analogous to the young men getting the herd to follow them. The oil companies lead the charge away from the truly revolutionary breakthroughs, towards business models where they're still relevant.
I met a physicist some 4 years ago who was working on his doctorate, on Cold Fusion-style research. At the time said he'd have to modify one of his papers to acknowledge some tokamak-fusion research that'd just been published - the experiment turned out just like he thought it would, but he had to mention it. Just finished his doctorate a month or two ago...
Scientific revolutions [emory.edu] come in waves. Right now we have the old-guard (established energy companies & rogue energy terrorists [whitehouse.gov]) fighting to suppress the coming paradigm shift. They'll lose eventually, and we'll all be better off.
