May be. I even see where are some TOKAMAK's problems. Also I see and feel Polywell's problems too and tried to explain you. Should we crush teeth of each other? I think that no.ladajo wrote:TOKAMAK will NEVER be commercially viable.
But problems will remain problems.
Patent office examinator told with doctor Nebel about Polywell as about conventional thermal magnetic trap, said that Polywell has not any novelty in conparison of Russian Galatea. As answer on my doubts on 2-stream instability you said me "Polywell is not a beam device" but investigation by Nebel disprove your this point.
Results of those research are that electrons should be extremaly thermal for avoiding 2-stream. Thermal electrons with large angular momentums will inevatably heat ions too.
Now aboyt beta. Beta=1 means that gas pressure is equal to mag field pressur.
When we talk about conventional plasma gas pressure is equal to sum of partial pressure of two spices: ions and electron commonly temperatures of which are not equal each other. But both those temperatures goes to be equalized.
Let's admit that Polywell works as desired (initially) and beta=1. This means that only electrons have gas pressure at the edge and ions have not. But after thermalization? Beta authomatically will become equal to 0.5.
Beta=1 is like swimming pool filled to the edges. Waves will pour water through the edges. Waves are instabilities. Whether you heard about plasma in any device where all types of instability are completely excluded? I did not. Not 2-stream, not any other type? Not any fluctuation in plasma?
I am saying simple thing: Neither TOKAMAK nor any other approach will alow to get commercial reactor in near 10 or 20 and may be 30 yuears. Has our dispute not begun from this point?
Do you believe that Polywell entried from conceptual phase? The device, the last version of which produced 0.15 W of power (your words - WB8 two orders more powerful than WB6)
Your right if yes.
