Is there an example of a noise source with which this actually can be
made to work?
Send the current through a couple of transformers
that increase the voltage to about 10 V. Put a diode and capacitor
in the output of the last transformer, and you have a (very small)
source of DC current at about 10 V. The noise source will cool
it's environment till it reaches absolute zero.
The electrical noise will be random in nature, but the diode
"creates order out of chaos" by converting the complex AC into DC.
Yes - But... this 1/f noise is not robust enough to make-up for the
transformer losses, normally - should you want to demonstrate an
available form of free energy (really heat and natural EM radiation)
There is the prospect that 1/f noise can be captured most effectively
with a fractal antenna... which can be thought of as a form of diode.
Actually the "form" which is etched on these is roughly triangular -
somewhat like the diode electrical symbol. A few folks will even tell
you correctly that a tiny amount of free-energy is available by
rectifying the output of a fractal antenna, or other kinds of
efficient antennae like the helical torus (CTHA), or Avramenko's plug.
These are well known. The common name for it is a "crystal set" :-)
Yes, I know. Most of this energy could be 'free' but still originate
primarily from your local broadcasting tower or from ambient heat ...
but nevertheless, it would be interesting (to perpmos at least) to see
if it is enough to keep a spinning top in motion for a time-frame of
years.
I don't know about a spinning top, but a crystal set (or a diode radio,
if you're the lazy type and don't want to fool with a cat's whisker and
germanium crystal) will keep playing top 40's music and advertisments
through a headset with no (apparent) external power for as long as you
care to listen. There's no question at all where the bulk of the energy
is coming from at the leads of an antenna these days!
And the stuff you hear on the headphones is just AM -- there's lots of
other stuff coming out of the antenna too that you can't hear that way,
because it doesn't turn into useful sound energy using a simple diode to
demodulate it. It still would produce useful electrical energy, though,
if all you wanted the antenna for was power.
Here is a suggestion from an old post that I made a while back, using
1/f and the spinning top toy, but never got around to trying it.
The LEVITRON (tm)
http://www.levitron.com/
has been argued to be a "stolen" invention, so buying it from the
turkeys who mis-appropriated it is a problem, but nevertheless we know
that when the top spins in the range from about 20 to 35 revolutions
per second (rps) it is stable - but unstable above 40 rps and below 18
rps. After a few minutes of spinning it always reaches the lower
stability limit due to air friction and falls. The spin lifetime of
the can be extended to about 30 minutes by placing it in a vacuum.
Pretty cool! And I confess I don't understand how it works. I would
have thought the spin would need to induce a current in the top in order
to make the levitation work, and that would produce a drag effect (a
counter-torque, I suppose you'd call it) that would stop it in rather
short order. But that clearly doesn't happen.
There is a "powered" version that requires a battery and will spin a
very long time even with no vacuum.
One would hope so...

The goal of the PM spin top (PM = either permanent magnet or perpetual
motion, depending on you boldness) is to make a device that will spin
for many years with no battery, only a tiny amount of extra energy
which could be supplied from 1/f or ZPE, assuming that some of it can
be rectified. Perpetual motion may be forbidden by someone's
so-called law and by our patent office, but our solar system and every
atom in our body indicates that things can spin for many billions of
years without loosing much, and that should be adequate encouragement
for present needs.
Actually, conservation of angular momentum requires that the sort of
perpetual motion exhibited by solar systems &co must be really
perpetual. Gravity waves can siphon off some of it, but after the
planets fall into the sun and the sun picks up their spin, I don't think
it radiates anything further since it's rotationally symmetric -- so it
just keeps spinning.
