Re: tesla coil powered lifter
Original poster: "Peter Terren" <pterren@xxxxxxxxxxxx>
Look at a real lifter capable of actually lifting its own weight of
4.2g here. Also without the pseudoscience and 'antigravity'.

The conventional small lifter runs (just) at 20 - 25kV DC. It may run
at 25kVAC, however there are two problems. First is that it is quite
difficult to get 25kV RMS AC at 50Hz unless you have an x-ray
transformer. Secondly 25kV RMS AC is 35 KV peak so the corona wires
need to be 1.4 times further away to avoid arcing.
A Tesla coil runs at high frequencies and will have the same problem
as AC PLUS there is the fact that a TC is not a continuous wave
device but rather gives short bursts of 100kHz so the voltage is not
sustained. Possibly a VTTC might do it as this is CW. There are also
likely to be capacitative effects. A TC is designed for streamer
growth and long sparks but this is undesirable in a lifter.

Anyone who has played around with high voltage has probably seen an
anti gravity lifter such as the one described here

Having finished my most recent coil I was looking for another
project to work on and started researching a lifter. The lifter is
easy enough to make but I didn't have the 25+kv DC power supply to
lift one. What I did have was a tesla coil. I have to say that I
never really expected this to work because a tesla coil produces AC
unless I'm terribly mistaken. I built the lifter based roughly on
the instructions from the website. I ran 26 gauge magnet wire from
the discharge terminal of my relatively small tesla coil and I ran
the ground wire to ground. I powered the coil up and got some sparks
and corona from the lifter but no flight. As far as I can tell a
tesla coil can't power a lifter. I'm curious though if anyone else
has tried this with different results.
