u/MBIRKE

Encased in a tube because I took it to my school’s science fair. Setup with 1-4 mot to vary arc length. Using microwave oven caps and a big 450 uf cap parallel to mains to reduce reactive power and to not make the breakers trip, works better than a typical mot ballast. I used a remote controled servo to iniciate the arc. Around 180 cm or 6 ft tall.

First video 1 mot, second 2 mots and final video all 4 mots.

It would be easy to seal the tube and try some low pressure vacuum stuff, what do you guys think?

Btw, first post and old project.
