Sure. Now turn one 180 degrees and place it next to the other. Is there a null at the center between them? Or do they make one big magnetic field that an electron bounces off of as though it were one big coil? It gets... complicated and hard to visualize. Magnetic field lines never end and they don...

A stand along N:S configureation (two and only two coils) would NOT have a null field between the magnets. The field would be almost as strong at the point midway between coils as it was in the middle of each coil. This is what I'm not clear about. Intuitively I would expect a particle at the cente...

I have no objection, but I would suggest snagging the images rather than hot-linking to Wikipedia.

AHA!!! That is how you do it! Thank you blaisepascal. Unh, how did you find the URL?

The other type, the "virtual" solenoids aren't as obvious: Around each of the 8 vertices of the cube, there are three large currents from the three adjacent physical solenoids forming a triangle (a very curvy triangle, but a triangle) with the currents going counterclockwise when viewed f...

I thought the whole point of this was that it's not what WB-6 and WB-7 have. Are you saying WB-6 and WB-7 don't have N:N and S:S? Why would we be arguing over whether it's necessary if we already aren't doing it? Let's be very clear here: when I'm discussing N and S configurations, I'm talking abou...

I knew that an icosadodecahedron was a rectified dodecahedron, I just wasn't sure if WB-8 was planned to have that topology. Well, now you know. :wink: Please check the FAQ linked in the first sticky topic in each of the technical fora. See where you think your description would best serve and we'l...

A fully truncated (rectified) dodecahedron is an icosadodecahedron. QED. I knew that an icosadodecahedron was a rectified dodecahedron, I just wasn't sure if WB-8 was planned to have that topology. One key with seeing the WB-6/7/8/8.1 configuration as a "cuboctahedron" is recognizing that...

http://en.wikipedia.org/wiki/Polywell If the configuration is looked at as solenoids on the faces of a polyhedron, then the polyhedron chosen must have an even number of faces at each vertex, so that the polarity of the solenoids can alternate. Infinitely many polyhedra satisfy this property, for i...

Re: PIC Simulation of Polywell

I'm surprised that the paper by Joel Roberts presented at IEC 2009 has not generated more discussion. The paper is an independent analysis of a poylwell using a credible particle in cell approach. The analysis is very encouraging on a number of points, including his conclusion that "Polywell r...

I think we can agree to disagree. That is one thing that differentiates a myth from an accepted fact. So the myth is established. Myth - "A hot water heater properly configured can deliver enough rocket thrust to launch itself into space." I think we can agree that a hot water heater , me...

Re: The end of the world? Or the end of fossil fuels?

I wonder whether the LHC scientist already witnessed some fusion events during the device's operation. Maybe the proton densities are not high enough for that by intention, but I can imagine a proton smashes into another once in a while. Since the whole intention of the LHC is to smash protons into...

More importantly, would be to stop building coal burning plants until we solve the problem which is an important step to solving our co2 emissions problem. It's solved: Use Aqueous Froth C02 capture ... According to that link, Aqueous Froth CO2 capture uses calcium oxide (CaO) as an agent to captur...

Aren't charging times coming way down where we are talking about charging times in the order of minutes as opposed to hours? MSimon suggested a rough working figure of 1 Wh/kg mi, which would mean that a car the size of a Smart ForTwo (curb weight 730kg) with one driver and stuff (figure 70kg) woul...
