Also to complement this, you can have a look at the latest image on the http://www.emc2fusion.org/ of their reactor with helium plasma. If you look carefully you can see the beams (meaning where the electrons are). Or perhaps that's just glare from the camera (if you are a sceptic)

I think the electrons mostly circulate in and out of a cusp and do not make a full circle along the field lines. Like in my simulation videos. Other simulations have been done by different people and they show the same thing. When an energetic electron gets close enough to a coil (penetrating field ...

What I see is basic physics. F = ma = q(E + v X B). If the grid is static, the electrons see a constant field and v is always increasing. Basic physics says that energy conversation is maintained. The potential+kinetic energy of the charged particle is constant in a static system. This is about as ...

@Indrek - I have clearly failed to explain things very well. I have been involved with the "free energy" community for the past year or so and it is quite amusing. If I have accidently used their terminology it is a mistake. The point I'm trying to make is that the E field for a MaGrid is zero in t...

@Indrek again: The staic well is a problem. An electron can circulate and pick up energy - it does not have to cross the well going up and down hill. It can continuously go down hill until its energy exceeds the containment voltage. The basic force on the charged particles is q*(E + v X B) = m*a. S...

Indrek, I totally agree with you! But the physics of the simulation follow my math notes really well - in other words I'm checking the code against theory. I didn't publish my notes on the static well because they indicated exponential growth and no stable orbit - which didn't look too good. The si...

I don't know, but I've had no indications. And I didn't mean to be disrespectful (although granted I almost always sound like, but don't mind that I really mean good). It's just I've been through this myself and I've got various fantastic results before (as errors) so I have lots of scepticism as I ...

There's another way to interpret this: 10 pixels of realistic particle movement and lots of noise. If none of you people have ever done software engineering before, I'd like to explain a few things: you test it you test it you test it. And with the most simple things at first. So in this sense this ...

In my simulations well formation doesn't seem to be a problem. With the quasi-neutral model even, electrons still do spend most of their time in the middle. And if I crank up the electron current then the electrons will indeed form a quite symmetrical sphere. http://www.mare.ee/indrek/ephi/wb1/wb.gi...

The simple magnetic bottle confinemenet in my simulations is poor as well. Here you can see how the confinement scales with the strength of the magnetic field in my simulations: http://www.mare.ee/indrek/ephi/confine1/ This is a pure magnetic bottle simulation, no electric fields present. Comparably...

I don't really understand very well on what I'm seeing but it looks nice. About calculation speed. For me it takes just a few seconds to calculate a 100MB grid. This is thanks to using analytic forms (and in part to my quad-core Intel system). If you don't trust my sources you can try the Dolan's bo...

I've tried to figure out better ways of doing things but it's going slow. Here's where I am right now: http://www.mare.ee/indrek/ephi/wb1/ (warning, lots of images) http://www.mare.ee/indrek/ephi/wb1/wb1_01_bf_lic.jpg I think the field within the magnetic ball should be close to zero, maybe that's t...

I just realized something. Which I guess was already there but now I understand it. With the wiffleball formation, the amount of electrons needed to negate the b-field is obscene. That is if it was electrons only the amount of space charge would be gigantous. This means it's impossible to have the w...

The resident expert, drmike. I have a question. If I have 48 million particles and I want to produce a smooth magnetic field out of them, what are the established algorithms for doing that? I have a few ideas myself but I just realized that I'm a clueless amateur. So before I make a complete fool ou...
