Index page. Polywell. Polywell WB-6 model assembled The polywell was developed by Robert Bussard as an improvement over the fusor. It uses a negative plasma instead of a negative wire cage to attract ions. Dr. Bussard theorized that a polywell could potentially produce net energy. His company developed the initial devices for the U.S. Navy. Description[edit] A polywell consists of several parts.
Gas is puffed into the cage. Development[edit] Fusor[edit] A homemade fusor Farnsworth–Hirsch fusor during operation in so called "star mode" characterized by "rays" of glowing plasma which appear to emanate from the gaps in the inner grid. Taylor Wilson presenting fusor work to Barack Obama, 2/7/2012 A Farnsworth-Hirsch fusor consists of two wire cages, one inside the other. A benefit of a fusor is that it loses very little energy as light; it has low radiation losses.
The fundamental problem with a fusor is with the grid itself. Elmore-Tuck-Watson[edit] An Elmore-Tuck-Watson (ETW) fusor inverts the charge on the grids. The Polywell Blog. Polywell Fusion in 6 Steps :-) Polywell.
