Think of the ions as bowling balls and the electrons and ping-pong balls. In the same force field, the ping-pong balls change direction quickly, but the bowling balls don't change much. So when the ions fall into the center of the polywell, they don't stop, they keep on going until they reach the co...

No, it's not stupid. Do a web search on "proton beam inertial confinement fusion". You will get several 1000 papers on the subject. It's just not likely to be cost effective.

tombo, check out Nanomagnetics and their ferrofluid etalons. It is an interesting way to view magnetic fields. You get a visual impression of the magnetic field, but it is an indirect one. I want to say it's a Fourier transform, but it's not quite that "simple". I had fun with the math on that probl...

I like the "geological near future". 5 to 10 kyr fits that description!

Thanks for posting, most interesting.

The Pioneer anomaly is a ranging effect. But it could be we aren't measuring it correctly. And it could be that the tidal effects are not changing the radioactive material, but they are changing the measuring equipment. A slight change in distance between detector and source might be in the range of...

It's not really about "constants" not being constant. These guys have to ensure tidal effects don't do something to their detectors before they invoke neutrino interactions. It'd be cool if there is a nuclear or weak force interaction, especially since neutrino's oscillate. But there are simpler rea...

I have no problem with reprocessing, especially metal fuel. But they show the placement of the typical installation underground and sealed, so it seems like it is supposed to just stay there. Maybe that's a detail they just haven't worked out yet. If the whole thing is built as a shipping container ...

Metal hydrides are interesting beasts. If that is the basic idea, I think the refueling will be challenging. It's fine for a 10 year battery (or even 50 if you don't suck that much power out), and they show it buried under ground, so it can stay there forever - but when the energy runs out you have ...

Here is the source "Hyperion web site"

My vote is scam. There is absolutely no information on what kind of nuclear power it is - radioactive decay or fission from neutrons. You'd think they'd be bragging about something!

But if they can get people to accept nuclear power sources, that's a plus.

I don't quite see how you computed the coil power. I would think the coil power scales linearly with radius where the power generated scales as r^3.

Check out the papers here: http://www.askmar.com/Fusion.html I'm sure it is covered there somewhere.

The simplest way to eliminate shooting wars over plants is to change the laws. Once plants that have been in existence longer than humans are no longer "illegal", the money going to farmers vanishes and the desire to protect those farmers vanishes too. The "war on some drugs" was fabricated to help ...

For its time, the Cray 1 was an awesome computer. Today's game machines run about as fast, and a workstation has 1000 times the capability at one millionth the cost. Wait till next year! :D

I loved Tron. It was a great cartoon that fed my imagination.
