Original poster: "Scott Bogard" <teslas-intern@xxxxxxxxxxx>A plasma ball is not a Tesla coil, but it operates on the same principal (resonant voltage gain). A Tesla coil, is a resonant, air core transformer. A plasma ball uses a ferrite core transformer, which is also operated at resonance. A plasma ball puts out about 8-20kV at about 8-100 kHz, whereas a Tesla coil, puts out much higher voltage, 100kV-10MV, at a generally higher frequency 90-700kHz. A Tesla coil (usually) is powerful enough to make streamers in the raw atmosphere, whereas a plasma ball, uses a low pressure, rare gas atmosphere. Tesla coil streamers are generally very dangerous, and plasma globe streamers, are generally not (unless you remove the glass!). That is about it! Both are very cool!
