>Idea - what if some highly skilled amateur device maker (a.k.a. not me) were to create a feedthrough with a small piezoelectric device (damn it Jim, I'm an engineer, not an English major)that formed a bridge between the fusor chamber and the room. I envision a pair of free moving cylindrical plates with the piezo in between them. The pressure difference would pull against the piezo rather than pushing, but would still cause a current. Even at very low pressures, I would think it would be sensitive. Piezos are cheap these days too. Comments?
Are you talking about something along these lines?
