ITER running at 500 MW will produce around 250 MW or more of neutrons. My recollection may be off but it is the right order of magnitude.A Polywell running at the same power production rate will produce 5 kW of neutrons. Closer to 80% for ITER's D-T reaction, so emphasis on the 'or more' there. ITE...

We will be happy to sell Polywell technology to the Chinese and they will be happy to reciprocate and sell us any technology that they develop. Ha! [soapbox] Except that America refuses to buy or license cheap and simple Russian rocket technology. They've actually passed a law saying that NASA is o...

Re: Shielding
Except for one minor detail. And yet you still believe nuclear power aircraft would ever get built? Try just for a moment to apply your vaunted education (aircraft operations especially) to space shuttle programme, and try and see what is wrong with that picture. Nothing in real life comes so close...

1) I am not certain that fast ships can compete with 3x faster aircraft which are also more flexible in where they can pick up and drop off cargo. 2) Only up to a point. If you need to deliver to three places at once you can't use two ships. 3) Any engine/fuel cost that propel 100tons at 100knots co...

A polywell could certainly drive a small ship that fast, but why would anyone want to build such a ship? Do you have any information for the proposed market? Some high speed ship designs, past and future: http://www.mshipco.com/ - made the M80 Stiletto (50kt brown water) http://www.austal.com/ - mak...

Re: Shielding
I guess you have never heard of the Kennedy Space Center. Have you ever heard of Kings Cross? Famous railway station in London. Featured in the Harry Potter movies. Has the original Victorian engineered roof. Quite a lovely station. Has been in use for well over a hundred years. For most of that ti...

And it is a problem of aerospace engineering, not of nuclear nor anything regarding the Polywell. The whole 'implications' sign you might have missed on the way in. Talking about why certain outcomes are very unlikely is well within the remit of this forum. Oh, wait, you are expecting Bussard to bu...

Speaking of weapons, I was thinking of these hi power lasers the armed forces are developing now. A problem with these is the darn power it takes to drive one. Hopefully solid state technology like the JHPSSL project will solve the weight problem. A combination of the diesel-electric and super-capa...

Re: Polywell is a terrorists nightmare.
Reduces world dependency on oil, removing funding and political power from typical terrorist sources of money and influence. 1) The middle east is economically dependent on the world buying it's oil. What woudl happen to the OPEC nations if demand for this export were slashed? The collapse of econo...

Because I'm a nuclear engineer. Yes, and? I'm an engineer too! An aerospace engineer. Whenever I raise an issue that fall under my education and outside of yours (like SSTO, ground-side aircraft operations, or rocket science) you treat me and my views like filth. So tell me, Mr Fellow Engineer, why...

If you know how to miniaturize Polywell, there are a lot of folks who would be interested. Well, you see, it's like this: You go to any of the polywell sites, fast forward to the end of pretty much any paper on the subject, and then pay attention when Mr Bussard says he could build a Q>1 reactor tw...

Re: Military looks at SSPS - polywell an alternative?
I don't think it serves quite the same need. They want to be able to beam power instantly to wherever they need it Not quite. The rectennas needed to receive the power would have non-trivial weight, volume, and deployment time. 'Instantly' in this case translates to 'a few days after the trucks get...

Nobody else here has the patience of energy to just tell you how stupid and ignorant you are. Right. Now that you've got that off your mind, onto the debate: Me: Self sustaining polywells can potentially be very small and road/rail portable. You: And would kill the transporter A) When has that matt...

Re: Neutron & radioactive waste production in p11B polyw
41Ca is not going to be very radioactive. As I just said, radioactivity is not an issue when it comes to superconductor failure. Activation rates will not be really high because the neutrons coming out of the reactor are going to be at 2 Mev or greater where the capture cross sections are low. Why ...
