The strange thing about this thread is that it's clear the basics are not agreed on. Leave aside the ions and the plasma for a moment. Let's have a simple lab model that shows exactly where the electrons go. The problem is that a plasma is a non-linear system. Even if you understand a simple subset...

The very fact there is a physicist in charge of all the national labs is astounding. That he's a Nobel winner is even more amazing. I think the key political notion we need to keep him interested is to point out that fusion is an alternative energy source. Polywell is just one of many fusion methods...

Howdy Dan, Think of the electrons in the magnetic field as balls on a string. As you swing a ball around in a circle and change the length of the rope, the ball will move slower or faster. The magnetic field is the string to the electron being the ball. The number of field lines inside the electrons...

In the field null region the phase space is uniform - all particle velocities are distributed in all directions. So under a line cusp, particles that shoot out along the cusp have no magnetic coupling - they go from zero field in the null region to high field with their velocity vector along the fie...

Vote for Fusion

I don't know if this will do any good, but I posted an idea on the Change.org website talking about fusion research. I left it general because all fusion research really needs to be hammered at, but feel free to leave comments about the Polywell!

You do have to register with the site to vote.

To get a picture on the electron sources, imagine two fire hoses pointed at each other. What happens when the water hits in the middle between the hoses is not exactly what happens when electron beams collide, but it's not far off. Not many electrons are going to get back up the other stream.

That's pretty cool! I wonder what the wear and tear is on the power generator section.

It fits in with the field of "energy harvesting", but on a much larger scale.

Thanks for posting it!

That's a funny one! Since the snow doesn't move, but the clouds do, pointing the microwave at the snow directly would probably work better and cost less! One of the cool ideas I liked back in the 1970's was the L5 Society - put a bunch of solar collectors at the L5 point and beam microwave power bac...

Re: Recirculation redux

I was reading Art Carlson's all that can go wrong with recirculation thread and had a few questions / observations. The biggest one is: is the current understanding of recirculation now that the electrons do not go out one cusp and back into a different one, ie, they go back in the same one they go...

Neutral beam heating used in Tokamaks would work just as well. Using a beam of neutrals is an energy hog, but you don't have to worry about the electric or magnetic fields. Only ionization impact will convert the neutral atom to be part of the plasma, and you would expect that to happen near the hig...

I guess another way to look at it is asset management vs. ass set management.
Yet another line I have to steal!!

The idea behind the circuit is ok, but you need to think of the stack of materials as part of the circuit. Set up the surface between insulator and metal to be the diode, and set up the beta emitter to be the electron source on the other side of the insulator (or diode). It's like trying to understa...

It's more a budget question. You have to put advertising and outreach in as specific budget items, so for larger projects you get results sooner simply because somebody is in charge of getting the info out there. Look at NASA and live TV coverage 24/7 on the space station. EMC2 has a really small cr...
