Any wire in the center would upset the electrostatic fields. These are what the device is all about. This is why one cannot langmuir probe the device to get much needed info. RH

Refrigerator compressors are not satisfactory even in tandem. Their valves limit them and they are single stage devices. RH

Yes, The Hirsch-Meeks multigrid fusor with electron source out near the shell should do better. It is more complicated and will cost more.

The patent drawings URLs were posted here earlier.
