Build a Nuclear Fusion Reactor at Home

FridayBob writes "For those of you tired of waiting around for someone else to achieve the holy grail of physics, now's your chance to beat 'em all to it. All you need is some basic engineering skills, this site and the inspiration necessary to make your very own 'fusor' produce more energy than it consumes. Hopefully, you'll have more luck than its inventor, Philo T. Farnsworth, who first built it in the 1950's after inventing the television some 30 years earlier. If you run into problems you'll be able to count on a enthusiastic support group, as the contraption seems to have developed a cult following over the past few years. Okay, so I'm skeptical that this approach will ever really work, but at the very least it sounds like a really cool science project!"

Twirlip of the Mists (615030) | more than 11 years ago | (#4972758)

Fusion is not dirty. Whereas fission starts with big, heavy atoms and breaks then apart, fusion starts with tiny atoms-- just particles, really-- and smooshes them together. Fission starts with uranium or something heavier, while fusion starts with merely protons created from hydrogen atoms electrolyzed from pure water.

Spamalamadingdong (323207) | more than 11 years ago | (#4972814)

but coal ash is. Currently, aside from the proton/boron-11 reaction (which yields 3 alpha particles) and deuterium-He3, I'm unaware of any fusion reaction which does not yield high-energy neutrons. The neutrons from deuterium-tritium fusion come out at 14.1 MeV, I don't recall the value for D-D fusion (which yields helium-3 and a neutron). High-energy neutrons create radioactive stuff by transmuting other nuclei.

The current state of fusion energy is pretty bad (way below a self-sustaining reaction) but this could still be used as a neutron source to drive a sub-critical fusion-fission reactor. Anyone who opposes fission power because of the spent-fuel issue wouldn't find this to be an improvement. (I would, because high-energy neutrons would be useful for transmuting fission products themselves, extracting their remnant energy and transforming them into stable isotopes. But I'm a geek and a technophile.)

Not at all similar. I looked into getting a grant to make one of these for a Science Museum. They are perfectly legal, pretty safe (as safe as many other common devices) and fairly easy to make - i.e., they have been built by many people and the necessary skills are common to many other activities.

It was either that or a liquid fuel rocket engine, and I decided that that was more dangerous, expensive and time consuming. I just moved across the country, so all my major projects got a year or two hold as I locate like minded geeks out here.

Anonymous Coward | more than 11 years ago | (#4972723)

You should really qualify your statement "Whit fusion of deuterium you get a whole lot less of the bad kinds of radiation".

Are you talking about direct radiation from the reactor in gammas or neutrons (alphas and betas are shielded)? They will be significantly more.

Are you talking about spent fuel? It will be very low.

Are you talking about the reactor complex? It will be higher.

So as you can see, just because it is fusion doesn't mean that it gets rid of the popular tongue vulgar word 'radiation'. But it does minimize (but not stop) contamination.

Ok, so the obligatory wise cracks aside, I want to know how many of you have thought about this seriously. I don't read The Sun, but I must admit that I have thought about this idea a number of times since '89 when Pons and Fleishman hit the headlines. I couldn't agree with Farnsworth more, if there is a slick way to get those nuclei close enough for fusion, then viola! Why use a steam-roller if a shoehorn will do?

Are you familiar with the effect called a phonon? It's a theory to explain why electrons superconduct in some crystal structures. If it can be done with electrons, perhaps it can be done with an entire nucleus.

You need exactly the same energy to create the antimatter as you get from the anihilation ("collision" is another nonsense, but let it be...). Unless you are going to mine the antimatter in some some animatter mine...

Re:Fusion is NOT the Holy Grail (3, Informative)

ottffssent (18387) | more than 11 years ago | (#4972768)

Matter-antimatter reactions produce gamma rays and other high-energy radiation. In order to harness this energy, you need to convert it into electricity, which requires actually absorbing the radiation. But since gamma rays laugh at lead or gold shielding and blast right through, there's a wee problem.

In contrast, the device mentioned in the article produces alpha particles (when configured appropriately, using Boron fuel). Alpha particles, if they touch metals, suck off 2 electrons to become helium atoms. This produces a net charge, and voila - electricity. The use of alpha particles in this way (such as from radioactive decay of certain isotopes) is well-tested. Since the majority (perhaps 95%) of the energy produced would be in the form of alpha particles, this type of reactor has the potential to be extremely efficient.

Regrettably, I don't have the background to determine whether it's all a crock or not. It sounds plausible, but all the best ones do. I'll believe it when it's powering my computer, but I'd donate a dollar to see if it could be done.

Re:Fusion is NOT the Holy Grail (0)

"But since gamma rays laugh at lead or gold shileding and blast right through":

This is absolutely NOT true. Lead is a good shield of gammas. But in reality a tank of water would be used. Water shields gammas (not as well as lead) and is much easier to use to transfer heat (or maybe create steam) to power electrical generating equipment.

Think about your staement though. Would gammas be dangerous if your body couldn't shield them? Its the shielding that hurts your body. Perhaps you were thinking about neutrinos and antineutrinos generated in nuclear fission.

What a load of crap. Good luck. These reactors require more energy to run than they produce. And D2 (deuterium gas) isn't cheap either. As for the oceans having enough deuterium to let us outlast the sun... cods whallop. There's obviously a mis count there, or the numbers are fudged. Maybe if you produced such a small amout of energy that one could make it last longer that's possible, but the Sun contains more matter than the rest of the solar system combined. The Earth's oceans arent' even a drop in the bucket (pardon the experssion).
The energy gain, or lack there-of, is why there are no commercial fusion reactors, energy output doesn't off-set cost and energy input. -- It's not like fusion hasn't been achieved! It has. You may even want to check out the muon catalyzed fusion reactions that were being done right up until a year or so ago at TRIUMF in BC Canada, same problems there too... and that was the most promising in a long time.

Link: [infi.net] Naturally, knowledge regarding the safety aspects of such an effort is essential! Among the more common concerns are the work
with the explosive hydrogen gas, deuterium. High voltage hazards abound as over 20,000 volts is needed to
accelerate the deuterons. Radiation in the form of X-rays and neutrons must be dealt with as well.

My favourite quote from the "construction" forums:

You can still use your garage as a instrument shack, but a cinder block box filled with iron filings and borax laundry soap $2.99 / 4lb box would work... out in the yard. Under would be best.

And to think, people have been messing around with particle accellerators and superconducting magnets all this time! Now the true path has been revealed.

who put this in the Science section? This belongs in Comedy. Or, if such a category exists, Retarded.

Sterility climbs among /. readers! (2, Funny)

JoeGee (85189) | more than 11 years ago | (#4972787)

If the stable one-atmosphere plasmoid [slashdot.org] didn't do it, and the DIY breeder reactor [slashdot.org] didn't succeed, there will no doubt be some ingenious /. readers who decide to create a high-energy neutron source out in their garage to remove themselves from the gene pool. CmdrTaco, Timothy, what is it with all the sterility how-to guides you're giving your readers?

sustained reaction (1)

TheHawke (237817) | more than 11 years ago | (#4972807)

Some of these nuts are actually pretty close to sustaining a reaction using this method.. One post had a guy running a sustained reaction for 10-15 seconds, pouring out alot of neutrons (3.29E+06 neutrons/sec). Unfortunately the energy budget is still too high (50 Kv @ 20mA (1KW)).
And all he had to say is that he had a good weekend.. *shakes his head in amazement*
If they keep this up, they might ecplise CERN's work as well as overhaul the X-Ray fusion reactor thats under development.
