This is a very exciting field, more specifically in combination with asymmetric capacitors.
Exodus Propulsion [0] under NASA’s lead scientist of electrostatics, Dr Charles Buhler and his team have been observing some very puzzling and exciting results. Would recommend anyone interested in this to check this out.

As far as I know they are still trying to piece together the underlying physics, but they are 10 years in and 1000s of experiments later, some of which has been reproduced.
I didn't realise there was a second EMDrive. Much like with the latter, though, I'm overwhelmingly betting on it being really hard to accurately measure small thrusts on the ground, rather than the drive being genuine.
It sure is hard. But have a closer look, these guys have been going over the results for 10 years improving, refining and discarding. What also helps is that they are highly regarded career scientists and engineers. Dig a little deeper on this one..
Not saying that it can’t be faulty experiments / results.. But truely nice to see some experimental science.
High voltage is a weird and fun area of electronics that a lot of geeks get into via building Tesla coils. Ive built a few HV things including a few tesla coils (pro-tip: a caulk tube makes a great baby secondary) and a can crusher with a 14uF 40kV pulse capacitor. I also briefly built a small 10x Cockcroft–Walton generator using the neon sign transformer from my Tesla coil but the caps failed rather quickly from abuse.
If you view the page on the Internet Archive all the links point to archived copies, you may have to step back in time to get something nicer than a 404 though
THIS is the 90s internet at it's finest.
I spent way too much time on this site as a kid....No surprise that now, in my 30s, I'm an electronics technician for a music store.
