At http://www.amasci.com/emotor/tvgen.txt they claim that one can generate
the high voltages one needs (thousands of volts) for a plastic soda bottle
motor by taping aluminum foil to one's tv screen and repeatedly turning
the tv set on and off. They recommend that one use a tv one is not planning
to rely on for long because apparently the act of turning it on and off
repeatedly eventually breaks the TV set.
I don't know much about TV sets but it seems to me that if you turn the
set on and off as often as they suggest, the most likely thing to break is
the on-off switch. In that case, one preventive remedy would be to plug
the tv set into a power strip with its own on-off switch, turn the tv on
and keep turning the power strip on and off. If the power strip wears out,
at least the tv still works.
The other thing I was wondering was whether, since the high voltages originate
inside the tv set in the first place, whether there is a convenient way to
reroute some of the internal circuitry of the tv set to use as a high voltage
source. For example, the tv tube has a plug with wires going to it and a
big wire going into a splotch of plastic somewhat closer to the tv screen
(I'm not looking at an open tv as I write this; I'm drawing on vague
recollections of having taken at least one tv set apart that I found on
the street a couple of decades ago.). So, if one unplugged the plug at
the back of the tv tube and cut the big wire going into the splotch of
plastic, maybe those would provide the leads one needs to use for the
high voltage power supply. I'm aware that one isn't supposed to poke
around inside tv sets and I have no plans at the moment to do anything
that I'm describing. I'd just like to know in principle whether something
along these lines would work.
In the book of Gilardini I mentioned in another posting, he says that
one way to get precision high DC voltages is to use special batteries.
Any idea what kinds of batteries he might be talking about and how much
they might cost (not that I'm planning to rush out any buy them)?
