Re: microwave heating

the gyrotrons in ITER are supposed to operate at around 170 ghz, which is a 1000 times higher than their gyrofrequency at 17 teslas...maybe it can work as a harmonic frequency?

Re: Bill Gates Sponsoring Palladium-Based LENR Technology

With hot fusion we know pretty well why it isn't practical, or at least we understand what is going on inside those machines to a fairly good degree. If they don't know what is going on inside a LENR device, then how will they ever hope to improve it, stabilize it, etc. If there are low energy react...

Re: tokamak question

Natural torus shaped (and rotating?) plasma. Perhaps. Some ball lightning has appears as a torus. smoke rings in fires, and atom bombs. Some magnetic loops on the sun come close to a closed torus. I don't know how similar the magnetic fields would be. Dan Tibbets Although if you notice, those examp...

Re: Bill Gates Sponsoring Palladium-Based LENR Technology

On the other hand, isn't it easier to get the anomalies that spur this research with palladium than nickel or other stuff? It would make sense to get a small lab to reliably reproduce such, then work out what exactly is happening, THEN start messing with nickel and cheaper materials and such. What ...

Re: tokamak question

I still don't understand yet why the tokamak has to be so huge though. Could the size be decreased if the miracle 100 tesla magnet came along? My understanding is it has to do with turbulence, related to unfavorable magnetic intensity profiles, and more severe as beta climbs. Without turbulence pla...

Re: microwave heating

If the microwave is close to the cyclotron frequency of a charged particle in a magnetic field it couples in resonance and can heat it easily. Off resonance the push is likely to alternate increasing and decreasing particle energy, and depends on thermalizing collisions for net heating. Hi Hanelyp,...

Re: space charge

Ha! That's still only 33.4 micrograms per cubic meter. A lot smaller than mr ITER.

Re: space charge

PS: Speaking of the Brillion limit, I think, without bothering to look it up again, that the excess charge limis is ~ 10 ^13 charges per CC, or ~ 10^19 per cubic meter. Dan Tibbets Are you sure? That would be more than a coulomb per cubic meter. I hope you are sure cause this is great news heh heh....

Re: Accelerator-driven sub-critical reactor

I've been looking at sites claiming fracking costs $1.30 for every $1.00 profit, without high prices and cheap credit the whole thing goes bust. On the upside, the Saudi's can't sustain low prices for any great period without having financial problems themselves. I occasionally listen to what Jim R...

Re: tokamak question

Centrifugal force is a consideration, but based on this abstract at least, it apparently is not a major concern in a typical tokamak. http://link.springer.com/article/10.1134/1.1545585 Dan Tibbets thanks Dan.

Re: diogenes will like this thread

It's too bad really. I love Gilmore and his musician work. Too bad his parenting wasn't as good. But who am I to judge? I'm not even a parent myself.

Re: Accelerator-driven sub-critical reactor

BTW I thought particle accelerators were kind of inefficient.. how efficient are they really? Electrically, DC particle accelerators are basically just like running current through a resistor (a current running from a higher voltage to ground). The electrical efficiency is basically just limited by...
