HT Superconductor & Graphene- The effects on Polywell De

There are 2 related advances in superconductors that have the potential to affect the progress of Polywell Fusion. One is the confirmation of a new ceramic superconductor with a critical temperature of 254 degrees Kelvin. http://www.superconductors.org/254K.htm and the confirmation at: http://www.su...
