Hi tombo, Check out the thread "theory>magrid configuration brainstorming". I think you would like it. Thank you for guiding me to this thread. I really enjoyed learning about your idea for creating a magrid. I especially appreciated the beautiful computer aided drawings and the way you were able to...

Hi tombo, The way that you are thinking about using the coil arrangement is different than I had anticipated so in order to give you intelligent answers I will need to study the polywell concept for a few weeks. However, I am prepared to give you answers that are not very inteligent right now. >Can ...

Hi jmc, Thank you so much for telling me about Keller and Jones. It feels great to know that others have considered the idea to have promise. Knowledge of them encourages me to explore the idea further. I asked my librarian if he could get the paper for me. He told me that he would need to know what...

Hi Solo, >I guess this would suffer the same issue as my proposal to join the edges of tombo's single-turn coils: the corners will have a field null.< This device is actually 6 different interlocking coils of wire which are meant to be turned on and off in sequence. The idea is not to contain plasma...

Spherical Electromagnet for Plasma Containment

Hi All, I have invented a spherical electromagnet that I think might be useful for containing plasma and perhaps for maintaining a fusion reaction. A photo of it can be found at the following link along with a full illustrations and explanation of how it was built and how I imagine it can be used. T...

Hi All, This is my first post in this forum. The following link shows a method for making huge spherical vacuum chambers without the need for a fixture. Specially shaped plates with compound contours are not required either. Regular sheet stock can be used. http://www.justodians.org/SphericalVacusta...
