Hendershot Replications

You guys would know better than me, since I know nothing about this project. But sloppy or loose curtains being blown around in the wind with a leather on top of a fur curtain would surely build a charge. Besides this thread what other places should I look for info about this?

Just search for Triboelectric in these renewable threads ... or via Google.

I was searching Google's patent data base for Triboelectric Capacitors and found some interesting stuff.
Patent 8004250 -- pyramid capacitor with coil @ apex - aug 2011
Patent 6974110 -- pyramid capacitor with coil @ apex - dec 2005
Patent 3013201 -- self excited variable capacitor/gen - dec 1961
Patent 4126822 -- electrostatic generator/motor - nov 1978

This last one is interesting in that you have TWO capacitors
that share a common plate -- like the Hendershot capacitor --
but this patent is small with liquid mercury moving back and forth
over smaller plates to create an AC current from that movement.

Meanwhile, the hand-made capacitor that I recently made was
tried with a transistor oscillator ... and interestingly, its pretty
stable, until you pick it up and squeeze it. When you do,
the capacitance changes to be "bigger" as plates get a little
closer together, and the oscillating frequency therefore, goes lower.
So in terms of being an ingredient for parametric oscillation,
if we had a means of SQUEEZING such a capacitor -- say with
a magnetic field -- then we could alter the capacitance and
produce AC currents.

So this idea presents itself.
Suppose you wrapped a hand-made capacitor around a metal
cylinder. Suppose beyond this is a coil. As the coil produces a field,
the diamagnetic aluminum plates will attract or repel coil
depending upon charge, yet the metal cylinder will spread
larger in diameter due to attraction. Oscillations will move
that cylinder so that it is altering from circular to slightly oval,
to circular, to slightly oval the other orientation, and so forth.
These subtle vibrations can alter the capacitance too.
So I would think we would NOT want to lock all these things down
physically, but rather we would want the capacitor to vibrate on the
cylinder. The mechanical oscillations need to be pretty slow,
and there are certain frequencies that will be "resonant"
with the physical structure of the cylinder -- in terms of making
it shake most severely.

Foam picnic plates are pretty strongly triboelectric.
Putting all this vibrating stuff on those plates might be interesting.

This guy's video is interesting .. when he shows how charging it
once was all that was needed ... and then it self charges from
then on ... the charge flow being established...

This is very interesting to me. I have a lot of reading to do. I was just discussing in another forum that everything from photons to molecules are oscillators.

I really believe you fellows are onto something here.

Regards Drak very nice build hope to have good results.
Good luck.

[dr.resist]

instead of horse-shoe magnet ... cant i just use 2 parallel bar magnets that give out the same magnetic fields toward the "coils" end ?

Thats cool MM I wonder if this would work as a diode in a circuit if it were made of copper,if the channel were made of copper, it might be worth the money to use as a mold.
Or it could be used as the blades in a wimshurst or testatika machine, very interesting.

good reading you Dave ..... had a similar thought ..... a wave guide of sort

What did you try?

Hello dr. resist
I have tried two 500uf for each 1000uf of the chines made CD60 type capacitors and a custom made 1:5 transformers but no luck in producing any bit of AC. please keep me posted on any light at the end of the tunnel

So did you buy the schematics from hendershotgenerator.com and follow them exactly?
If so, can we see some pics of your setup please?
I'm curious as I have a set of these plans and am going to try building one. I have my suspicions though. As there are one or two bits of information that are not included:-
Why are the capacitors covered in what appears to be red paper?
What value capacitors should be used? (they say 500uf and 1000uf bipolar but add no further specs as to voltage, current etc.)

Unfortunately finding capacitors of this value cheaply is not easy. Despite the marketing blurb saying that the whole generator can be made as cheaply as $100, the capacitors alone far exceed this amount.

Its not as if I gambled the family fortune on the purchase of these plans. So if it is a scam (and I am yet to be convinced either way) I won't have lost much there, but the parts to build the machine are at least UK£150. But I am interested to know if others have tried them and what they tried specifically.

Thanks MonsieurM
Very clever isn't it

horsepower????

It won't be the same horsepower. ... kidding.

Who knows dr. resist? You can try it and see. If it doesn't work, you
can next try attaching a metal plate to the back side of both magnets,
turning them effectively into a horseshoe.

By "same magnetic field", do you mean same exact value in Teslas?
I have speculated in previous posts to this thread that the strength
of your magnet will need to be MATCHED by the strength of your
solenoids -- using the least amount of current in your solenoids.
So if you have solenoids with not very many turns of wire, and a very
STRONG magnet, the solenoids are not likely to do very much.
Iron solenoids are different than STEEL solenoids. The former being
upwards to 50 times more magnetic field for the same current.

In terms of the magnetometer effect, IMBALANCE is what is wanted.
I've found that by placing a cylinder magnet against only ONE
solenoid, leaving the other w/o a magnet nearby, can cause
an AC voltage to be induced if you pulse the solenoids --
but only if they are counter-wound (as would be the case
with a magnetometer).

wrong plans- don't build the hoax.

Someone else pointed out that it is absolutely WRONG and a SHAME to use PINK capacitors. What where these guys thinking?

Look .. if you've forked over the money to buy plans -- you've violated the first rule of free energy. Don't EVER !!! EVER!!! EVER!!! pay for these scams.

All the information is available FOR FREE HERE and other places on the web.

The CAP values are too big ... just calculate the timing constant
which is 5 * R * C... where R is resistance and C is capacitance.
How small do you think you can make R?

Yes what a ghastly colour! I have no idea about capacitance values and their calculation. However I would be interested in any answers to my original questions.

1. Has anyone made a hendershot generator work?
2. Is anyone willing to show any evidence that they have tried these plans?
3. Why the red paper over the capacitors?
4. What methods have been tried to kickstart the process in a Hendershot generator?

for first Q , i would actually reform it to : has anyone even made the exact original 40/80 uf and what was the output wattage of that ?

for third Q, they said that they covered the brand of the caps ... and for the caps voltage being unspecified , they said that transformers are 220V so you should have figured out.
