D-T is the easiest and thus should be tried first. High school kids burn D-D. I see no reason to even bother with D-T. Besides you have to get all kinds of permits and stuff. D-D burns at 5 to 15 KV. pB11 burns at 50 to 60 KV. In fact D-D at 40 KV and pB11 at 50KV have the same reaction rate accord...

We can't go in there and say that its so easy to do that a kid could use it, because we need nuclear engineers and physicist to assemble and configure the device. Actually any reasonably competent Naval Nuke Operator could design the test reactor and WB-100. Especially given the collected instructi...

superconducters were suggested to reduce the overall power usage of the magnets. I think once you've run current into the superconductor you don't need to add more. As long as the temperature is low the steady-state current consumption should be zero. Yes, that would cut electricity consumption but...

Thanks!

Fusion Cross Sections

The advantage is that D-D fusion should be easier to obtain than p-B11. Actually no. Look at this graph. Cross Sections Where the reactivity starts to get useful (.1 barns - you get detectable reactions at .01 barns) the drive energies of D-D and pB11 are about equal. The required drive then for D-...

Some side reactions described here : http://en.wikipedia.org/wiki/Aneutronic_fusion 11B + alpha -> 14N + n + 157 keV 11B + p -> 11C + n - 2.8 MeV 11B + p -> 12C + gamma + 16 MeV As the hydrogen is not pure : 11B + D -> 12C + n + 13.7 MeV D + D -> 3He + n + 3.27 MeV Hydrogen with zero (as in you can...

2. Fission nukes - plutonium guaranteed Not necessarily. Future fission fuel may not be plutonium at all; instead uranium-233 would be used, created by neutron bombardment of thorium, a much more abundant element then uranium. And according to nuclear weapons archive: With deliberately denatured gr...

How could this scheme work to generate DC current from a constant stream of alphas when there would be no continual change in the magnetic field around the alphas? No one has explained to me how the electrostatic deceleration of alphas with a grid would become a source of current. Does the electros...

The least expensive thing would be a good simulation. Indrek has a real good start on this. For redundancy's sake, here is his website: http://www.mare.ee/indrek/ephi/ He even includes source code!!! Actually what Indrek has done is a discrete simulation. Very good. He has already used it to solve ...

How cheap ? And would you be prepaired to move to say the UK ? I'm wondering how many people would be willing and at what price/wage level to move to a community if one such existed to work on fusion research together in a group effort. My bags are packed. I've always wanted to learn British, heck ...

Bombs don't use tritium directly. These use lithium. Tritium is a bitch to store, and there is the problem of purity. He3, its end-product, is a neutron killer. Instead they use lithium deuteride, which is solid but the neutrons from a fission bomb make lithium produce tritium. To trigger a Teller-...

As for workers working only for food and room, get that idea out right NOW. We are talking about engineers and physicist with PhDs and the like, not to mention potential illegality of this idea. Not everyone involved of course will be a highly-qualified person, but these people will have a high eno...

If Bussard can achieve a model that produces net energy, how does he plan on extracting that energy? When using the p-B11 reaction, most of the fusion products are high-velocity charged particles. You can extract their energy in fairly simple fashion using charged plates; the plates slow the ions d...

If we fed protons and boron nuclei into the reactor in pulses, it could result in outward pulses of alpha particles. Induction (coils) could be used to impede the changes in magnetic field that would accompany the changes in alpha-current, and the coils would become a source of alternating current....
