An oddball notion

Postby VernonNemitz » Fri Jun 05, 2009 2:21 pm

Years ago, when I first heard about Bussard wanting to modify the Farnsworth-Hirsch design by using magnetic fields, there wasn't enough data for me to know what he had in mind, so I began to imagine....

This notion therefore may be totally off-the-wall and useless. It may have some entertainment value, though, so...

Have you ever seen an incandescent light-bulb filament under a magnifier? Tungsten is actually a pretty good electrical conductor, so a long long filament is needed to get enough electrical resistance. To fit such a long filament into the bulb, the filament is coiled, and then the coiled filament is coiled again. Some high-output bulbs have a third level of coiling of the filament.

What if the electrostatic grid in a Fusor was coiled, and a DC current fed through it? Then it would have a magnetic field that should mostly deflect collision-course ions. This idea would require that the entire electrical circuit be isolated from other circuits (including parts of it outside the Fusor), so that its wiring, as a whole, can be given an electrostatic charge (and DC induced to flow through it), but I don't see that as a particularly difficult thing to accomplish.

I do think there still might be a few spots where ions could impact the grid. Will enough of them be deflected to make the Fusor practical? I have no idea...have fun!
