I have heard there are plans for monster versions of these that
somehow collect and store atmospheric electricity. It is hard to
believe that any 'power' could be gleaned from them to do anything
useful because they only produce a high voltage charge.
Since voltage and current are reciprocal, you can use high voltage
discharges to produce high amplitude SPIKES....but power ain't
spikes...unless of course you can get many of them close
together...this has been the error in several possible f/e units...the
waveform makes all the difference.
Power has to be 'stretched' over time to be useful, it can't be spikes
unless they are fairly close together, that would be able to sustain a
load continuously, not jerk it off and on from power variations. This
could also damage the circuit from heating and current spikes.
Anyway, I would be amazed if you could get any useful work from an
electret...I've often thought those perpetual lamps that are claimed
to be found in tombs sealed for 2000 years, might well be duplicated
using an electret to provide high voltage to stimulate a phosphor
panel, or even sealed hydrogen gas (which I understand emits light
when excited with phosphors). Cold lighting...
So I wouldn't count on electrets as a source of real power unless they
were coffee table sized units, which, btw, I understand those plans
tell you how to build...high voltage builds to a certain level,
discharges across a spark gap inside a vacuum tube to minimize heat
losses, dumps and stores the energy in a capacitor that feeds a DC
load. It is possible. Might even be able to increase the output by
blowing dry hot air near the electret (kind of like stimulating a
VanDeGraff for higher outputs using a hair dryer)....
