Anyone got a 3ph motor to do a quick One-wire bulb circuit by Brian Prater?

[Goat]

Hi All;

I came across this stupid simple One-wire bulb circuit by Brian Prater that was on page 59 of the RE-OU-v6_1.pdf document on RV setups and was wondering...

Has anyone ever tried this? 

Can anyone try it if they have a 3 phase motor and a 60W bulb?


Here's the details :

3.6 One-wire bulb - Brian Prater (Cavetronics Labs R&D)

The one wire bulb works on the concept of magnetic reconnection.
Magnetic reconnection is the process whereby magnetic field lines from different magnetic domains are spliced
to one another, changing the overall topology of a magnetic field. It is a violation of an approximate
conservation law in plasma physics, and can concentrate mechanical or magnetic energy in both space and time.
Solar flares, the largest explosions in the solar system, are caused by reconnection of large systems of magnetic
flux on the Sun, releasing in minutes energy that is stored in the magnetic field over a period of weeks to years.

Magnetic reconnection in Earth's magnetosphere is responsible for the aurora, and it is important to the science
of controlled nuclear fusion because it is one mechanism preventing magnetic confinement of the fusion fuel.
In an electrically conductive fluid or plasma, magnetic field lines are grouped into 'domains' - bundles of field
lines that connect from a particular place to another particular place, and that are topologically distinct from
other field lines nearby. This topology is approximately preserved even when the magnetic field itself is strongly
distorted by the presence of variable currents or motion of magnetic sources, because effects that might
otherwise change the magnetic topology instead induce eddy currents in the plasma; the eddy currents have the
effect of canceling out the topological change.
See http://farside.ph.utexas.edu/teaching/em/lectures/node84.html for an explanation on magnetic energy.

The diagram to below gives an overview of concept and
wiring.

The system uses 64 W from the line input, running the motor
and light, the light being 58 W. The motor running at 1725
RPM without a light uses 58 W, where the light uses the 58 W
that the motor has past off to the light bulb, matching the
current. So we get 116W out version 64W in, as such there is
about 52 W free.

The input is about 118 VAC single phase. At that voltage the
light will use about 58 W (same as the motor). Now when
looking at the voltage coming off the motor without a light as a
load, it reads 92 V no load. Now when the motor output is
loaded, it rises to 109 V and the light is lit up. So a rise of
about 17 V.on the output of the motor.

Specific:
63.67 W-in - 42.45 W-out = 21.22 x 2 = 42.45
42.45 - 63.67 = -21.22 (+- 42.45 bandwidth)
106.12 W-out (63.67+42.45) - 42.45 = 63.67 W-used
= 106.12 total W-out / 63.675 total W-in = 1.667:1 gain

This motor is started with a smaller motor, as there are currently no run or start caps on the system.

The remarkable fact is that the light once lit, stays lit after you switch open one of its input lines, as to be lit by
"one wire", costing just 5.8W for the 58W of energy used (not to account the other 58W running the motor). So
the light burns on 58 watts one wire, and in fact uses the same amount of energy, switched on or off… "one wire
or both wires" cost the same energy. (the light resistance is around 174-280 Ohms while lit). Node-anti-node,
wherever you are at it you get it with one wire.

You can run some DC caps (e.g. 8900μF 250VDC) off where the light is hooked up, through a FWBR. You can
then get 89 V at 0.5 A for free while running the light and motor.
Total input = 64 W; total output = 158+ W; 158/64= 2.46875 gain

Looks pretty simple, wish I had a 3 phase motor to try it on.

@ All

The suspense is killing me, I see 30+ views on the diagram which is "stupid simple" but I just don't have a 3 phase motor.

Hello, anyone out there a 3 phase motor and a 60W bulb?

Regards,
Paul

@ All

If we can get a 3ph motor to run and light a 60W bulb and get 2.46875 gain wouldn't that be a good thing?

@ All

Did anyone notice that the light bulb can be light (pronounced lit in english) with only 1 wire?

If breaking the circuit at the bottom end of the circuit (see above circuit) continues to light the bulb then it is truly a "One-wire bulb", how then is the light bulb being light (lit) if the circuit isn't complete?

Please replicate this if you have the means and let us know.

@ All

Well after 50+ views on the schematic either nobody has a spare 3 phase motor and a 60 Watt bulb to do the test or not enough people are interested enough to give us feedback.

I'm going to sleep on it overnight and buy a 3 phase motor and a 60 Watt bulb tomorrow if I don't hear from a brave soul willing to try it.

Bye for now.
