Re: Fusor without inner grid?

I have looked at POPs, and I've also looked at "Beyond the Brillouin limit with the Penning Fusion Experiment" also by the same group. Pops tried to oscillate a sphere, my device oscillates a cylinder. The cyclotron is a very well known, cylindrical, periodic system capable of reaching the desired e...

Re: Fusor without inner grid?

I'm going to agree with you that a simple fusor is a dead end energy wise. Short summary: Grid collisions, a growing cool clump of ions, and only a single chance to accelerate each new ion ensure that it's not going to be sustainable. That's why, at least in my device, I'm trying to create an enviro...

Re: Hello!

Hi Benson! I run a makerspace in Provo called ProVolt and we have a bunch of tools and equipment that might be of use. I'm also wanting to build a fusor, as well as a new design of my own. If you feel like collaborating, come on down sometime. We usually get together Tuesday and Thursday evenings. O...

Re: Fusor without inner grid?

This is very similar to what I am working on, and it does seem very similar to a Penning trap. I've done some simulations, and gotten some promising results. https://www.youtube.com/watch?v=RT6nvmN7GB0 I've looked at buying a cheap MRI machine that will supply the magnetic field. The one I've been l...

Re: lab electromagnet from scratch

All the work I see here is discouraging me from attempting to build the magnet I need for my proposed fusion reactor... I'm going to need an extremely uniform .5T field over an area of about 18", and the thicker the better. Fortunately, I realized that MRI machines have fields that meet my requireme...

Re: Deuterium ion speed at 30kv.

The 1mev level is merely a desideratum, a limit beyond which you are throwing input energy in a toilet. If you raise the energy far, far above this, it seems like you could use the accelerated ions to heat the "cold" ion cloud that forms inside the center electrode to keep the average energy there ...

Re: Best method for direct energy conversion?

Check out the atomic battery page at wikipedia. I think the direct charging generator would be a good option for you.

Re: Open Course on Plasma Physics Currently Available

This does look very interesting. I just signed up, but unfortunately the class started 2 weeks ago, and I've already missed one assignment... It's my college experience all over again.

Re: John Fenley Introducion

Thanks for the question, and the pointer to the patent law changes due to the AIA. First the question. I'm not attempting to overcome the Brillouin limit that way. The paper for the Penning Fusion Experiment hints that this limit can be overcome through a variance in space or time. My device uses ti...

Teaser for a new Fusor in Utah

Yesterday some friends of mine finished putting together the vacuum and high voltage system on this baby.

It's not mine but I just had to share.
