Garage door opener vs. Tesla coil

["Tesla list" <tesla@xxxxxxxxxx>]

Original poster: otmaskin5@xxxxxxx 

I looks like my coil murdered my garage door opener. While running 
the coil in the garage, the garage door  opened on it's own & then 
died. I now have to open & close the door manually. I was careful to 
position the coil far enough away so that no arcs could strike the 
opener or anything connected to it, and it still seems to have 
succumed to the coils effects somehow.

My question is, other than unplugging the opener, are there any 
preventative measures I can take to protect the garage door 
motor/receiver? Or is there just no safe way to run the coil indoors? 
I imagine the repairs won't be cheap so I'd like to avoid a 
repeat.  Thx for any advice.  Dennis Hopkinton MA
