Mag fields fall off as 1/r^3. I can't see how the sun's magnetic field could create the earth's field. The sun is only 10^6 times larger than earth, so it's field would be at best 10^6 times larger. But the distance is 10^11 meters, so 10^6/10^33 is really really tiny. Actually you should be counti...

High temperature superconductors can't be used for strong electromagnets. ITER uses niobium-tin and niobium-titanium alloy. Even if YBCO or BSCCO could be used, it is likely that cooling further down would increase the critical current density enough to warrant the effort. I see no reason to use hy...

chazmataz, My proposal for a test reactor will prove D-D and p-B11. If it works for D-D it will work for pB11. After that you build your 100 MWth pB11 test reactor followed by actual power producing plants. IEC Fusion Technology blog http://iecfusiontech.blogspot.com/ Scroll down. Yes, I have been ...

I recall that most of the energy released goes into neutrons. 66% of the reactions lead to neutrons according to wiki given the burn up of all reaction products. Given the lower energy per reaction c. 20 Mev vs 200 Mev. You get a lot more neutrons out of a fusion reactor than you do from a similar ...

have actually been contemplating the possibility that the first net-power polywell reactor should burn D-T, and dismiss the neutrons produced from the reaction as waste heat. There are problems with neutrons, one of them is that you have to shield the grids againts them. I recall that boron shieldi...

I try to be realistic. Enthusiasm is fine and is a powerful engine for this enterprise. The equilibrium between being enthusiastic and rational is the key point. In my opinion too many people try to see a far future ahead. Although p-b11 may be reachable the first generation of Polywell (if success...
