Electrodynamic fusion is not the solution to the helium crisis.

One of the things to come to my attention recently has been work done over the past 15 years by EMC2 on electrodynamically contained fusors. This is a different approach towards fusion energy than has been pursued by the DoE (Tokamak reactors) for the past 30 years.

I've also been made aware of the fact that we are having a helium shortage globally.

My thought was: since fusion reactors generate helium, perhaps commercially viable fusion plants will help offset the helium shortage.

Then I ran the numbers: A PolyWell fusion plant using the p-B11 reaction that meets the electric generation usage of the world today would make about 1 tonne of helium per year, while consuming about 1 tonne of boron and 100kg of hydrogen. That's assuming 100% efficiency, which is ridiculous. However, assuming only 5% efficiency means that it'll generate only 20t of helium.

That's nowhere near enough to offset the helium shortage.

ah - thanks for the link. (the main page is atrocious for actually finding anything.) it looks, to my math-impaired-technician's mind, as if they took some of the basic structure of the Farnsworth design and modified it so that magnetic rather than electrostatic fields moved the particles around. this, of course, introduced other design constraints, such as forcing the device into a polyhedral rather than strictly spherical configuration. the output figures are amazing... WHY ISN'T ANYBODY PICKING UP ON THIS???

(oh, and i take it that's Bussard as in "ramjet"?)
