Below is from another site by a very knowledgeable individual in electronics who wrote into Electronics magazines. As I asked him for his opinion about the Keshe device.

"I was asked for my views on the latest free energy fiasco.
Which apparently consists of a film on the inside of a pop
bottle.

The obvious answer is "Boy, a whole flock of 'em flew over
that time". But a more polite one would be to "Wait a year and
check back".

At that time, if the free energy was real, you would expect to
find several independent papers in Science, Nature, and in the
Proceedings of the IEEE.

The U-Tube demo seems to consist of a brief and high
impedance measurement of contact potential. Instead,
rerun the measurements into a realistically low load
for a realistically long time to see how much power you
can actually measure for how long.

Possible resons for any voltage at all could be a battery-
like electrolytic coating or the contact potential ( thermocouple style ) between dissimilar conductors.

Or, of course, an outright hoax.

My faorite free energy fiasco remains the magic lamp,
which I commented on.

As we have seen before, finding an unlimited source of free
energy would be the most unimaginably heneious crime against
humanity. Making Hitler look like Mother Teresa."
