got an idea about a HV variable cap. We were makin a ldpe plate cap, got done folding it up and realized it was all puffed up. So we pushed it down, changing the distance between the plates, and the capacitance increase. Design a proper box to put it in you could have a cap with a wide range. Our stack doubled in hight when the presure was released. Chris and Ramsey (Ramsey and Chris) via the interthingy
