Re: Pacmakers and Tesla coils = bad??
Already did some testing in that area with Medtronics (the large pacemaker
mfgr in Minneapolis). At a reasonable distance of 6-8 feet nothing shows up
that represents any danger to people with these devices. It did make a lot
of noise in a hearing aid so we tend to warn them as well. We usually
specify a distance of not less than 30-40 feet for all our shows with a 1
MEV coil operating at fundamental of 170 KHZ. Smaller coils running at 500
KHZ presented even less due to their lower power levels.
