With regard to HOW Marks seems to produce 'free energy' by his claim of
tapping into the earth's magnetic field, here is the response I received
from an anonymous contact when I asked how would one duplicate the Marks
device if it was a fraud and understood to be such;
> The Mark device is a battery powered switching power supply.
> There is ample evidence on the video to come to this conclusion
> without having talked to people that worked with Mark. Reproducing
> the device would take quite some time and money but any power supply
> engineer could do it.
In other words, an INVERTER if there is truly a battery involved. Most
inverters that I've seen convert 12VDC to 120VAC and can power ac
appliances for as long as the battery will last, but somewhere I have
seen a 9VDC (as in transistor battery which is easy to hide) that COULD
produce sufficient energy to drive a 50 or 100 watt AC light bulb...
Of course the battery would run down rapidly and if the toroid coil is
part of the circuit, it could heat up as more current was sucked out the
battery to compensate for the lower voltage which would account for the
reports of the device only being able to run for brief periods...
Here are the comments about the Marks device which lead to the idea that
there is a hidden battery and that it can only drive an AC load for a
Only light bulbs are powered;
"Over Unity, solid state electrical output for lighting, no apparent
input, appears toroidal in geometry or similar to a Hendershot
Generator, will not demonstrate device running motors. Video tape shows
three devices of different sizes."
Probability of batteries involved;
"Overheard to say while drinking "Well what if I do have batteries in
it? It's still better than anyone else can do."
"Finds investors, does demo, shows problem such as the device won't work
when upside down or it over heats, all of which can be solved for an
Hmmm, a mercury switch could easily be hooked into the circuit to make
it position dependent thus giving him an excuse to ask for more
Resistance to motion;
"...when the device is operating, they say it has a resistance to any
lateral or rotational motion, like a gyroscope has that same resistance
to a rotational (only) motion.."
Possibly a small flywheel as an energy storage device, spin the flywheel
up and let it drive a generator to produce high frequency AC as noted;
"When the permanent magnet(s) is/are inserted, the secondary coil
registers an output of about 80-100 Volts, on a regular VTVM as seen on
the tape. The tape calls this Voltage DC, and also says that it is
around 5,000 Hz, which of course does not make sense."
No indication in any report of noise such as a whirring sound. So a
small weighted flywheel balanced with magnets in its rim, as it spins it
produces high frequency AC but is that enough to drive a 100Watt
So one or more small batteries feeding an inverter to run the load, as
the battery power decreases, the entire circuit will overheat.
OR, a spinning flywheel using something like a 1.5vdc slot car motor to
produce AC to light a filament. What a neat scam!!
"...The outer toroidal coil overheats..."
"The converter package in the center of the toridal coil appears to be a
circuit to convert the pulsed DC component to AC."
