I see no reason to use D-T in a Polywell. Ever.

D-D should work fine at from 15 KV to 40 KV drive.

At 55 KV drive pB11 starts giving good reaction rates.

If you have to play with neutrons, fission has the advantage of being surrounded with water. Fusion needs a vacuum so it's hard to stop the neutrons and absorb their energy. In tokamaks it's called the "first wall" problem, and if you are going to use DD or DT in an IEC device you have the same pro...

Anti, I believe your plan would work if you were driving the truck while the unit was in operation. Don't forget to bring along your 3 MW power supply and tank of liquid nitrogen. You are going to need maybe 500 gallons for a decent run time. You will also need a vessel 12 ft across for decent neutr...

An accurate assessment in my book, and useful that you mention any reply needs to be the length of a sound-bite, rather than an essay on the subject.

Who will drive the truck?

I believe a truck load of fertilizer is cheaper and would do more damage.

BTW have you considered worrying about knives?

How about rocks? They are unregulated totally.

You know I believe that is why most rockets are situated to fly over water for the early part of their flights.

Working fission plants are made of 404 stainless. <snip> Did I mention that neutrons are easily shielded with water and concrete? We actually have the technology to do this. Ah! Good good. A couple of issues still though. For obvious reasons a polywell can't have water or other kinds of shielding i...

If you use water as the reaction mass it will provide more than adequate neutron shielding. And the people on the ground as it flys low for take off or landing? This is one of those 'non technical' problems with HTOL SSTO I mentioned earlier. 747 runways have very large noise footprints. You're loo...

The "cube" Polywell is actually a truncated octahedron. This is because the cube and the octa are duals as are the dodeca and icosa. BTW the gain reasoning is covered in the Valencia paper. I have also written up a simplified (but more detailed) explanation at : http://iecfusiontech.blogspot.com/200...

Good suggestions. My issue is that I am not a copy-writer, nor a scientist, but a web developer. Traditionally in this sort of medium a company will hire a marketer, who will write the content with the aims and missions of the company in mind. So I am hoping that when Dr. Bussard sees this, I will ...

Letters to the editor should be kept short. 200 words max.

100 words better.

Irrespective of reactor design, p11B fusion produces 'less than 0.2%' of its total output as neutrons. http://en.wikipedia.org/wiki/Aneutronic_fusion#Residual_radiation_from_a_p-11B_reactor] . Even if we assume 0.1%, then a 1GW 'regular size' power plant will still produce a MW of neutron flux. Ass...

Anti- carrot, What the heck does peer review have to do with Bussard's machine working? Climate science is supposedly peer reviewed. It is looking shoddier by the day. Peer review often falls into the consensus trap. Peer reviewers don't exhaustively study a paper. They just give it the once over. L...
