A vacuum tube plasma generator with some cesium and lithium chloride on the output electrode. The only gas burning in this device is air, so yes, that flame is purely electromagnetic.
I started filming this video today (well other than the build clips), even though I built this device a while ago. I've played around with component values and honestly wanted something a bit more impressive, but at this point I need to produce some videos for you guys. :D I will drive that poor tube a bit harder when it comes to filming the clips for the vid though!
