I built a 7 foot high 10 million volt tesla coil. :-)

Neighbors thought UFOs had landed.

Cool! Can we string a few thousand of them along the border as bug zappers?

I built a 7 foot high 10 million volt tesla coil. :-)

My Tesla coil was more conservative. The secondary was a 2 inch diameter, 30 inch long mailing tube. I spent 7 hours winding the secondary with 36 gauge magnet wire. It looked like smooth copper foil. The capacitor was built with a stack of 12" mirror tiles. Spark gap with 10d nails. Primary with some 12 gauge wire stripped from spare Romex. A 15,000 volt neon transformer was used to excite the primary. I powered it up inside an 8 X 8 foot bedroom at a friend's house. The snaky violet discharges went all the way to the walls. After days of work, the total run time was under 5 minutes. Too much RFI.

If those things work, then why aren't we using them?

What did the FCC think?
