I am searching my files as we write looking for Peltier tables of output. If sheets of bonded junctions would be made, this approach has 10X energy output over the photovoltaic approach per square ft. of space. Uses only temp differential from the ambient environment.

You have written the best essay on this subject I have ever read. What an interesting concept, well researched. By carefully stating the subject, you also leave the door open to further research on a collective basis, for a group effort to build practical applications. This paper deserves recognition in a serious scientific journal. Cheers Warren

Try this one:
What is Heat #3
For about 10 years I have been studying the effects of
heating and cooling associated with the phase change of
liquids with the hope of building a simple generator of
electrical power around the phenomenon. The reason for this
interest is based on the theory that energy can be extracted
from the ambient background via thermal differentials. My
line of thinking really took off back when I experimented
with the all too familiar Peltier junction devices found in
electronic cooling devices. Would you believe that most
people do not understand how these devices move thermal
energy through a current flow across a semiconductor
junction. Historically we find that German physicist,
Thomas Seebeck back in 1820 observed that when heat was
applied to a junction of copper and steel wire that
electrical energy resulted. Later in 1834 Jean Peltier
discovered that when a direct current was applied to two
Dissimilar metals the junction got hot or cold. It was not
Until 1838 that Emil Lenz clearly showed the importance of
Both Seebeck and Peltier s discoveries by placing a drop of
Water on the junction of dissimilar metals which froze then
Melted when the polarity of the direct current was
Reversed. These discoveries remained dormant for over 100
Years because of the unavailability of semiconductor
Materials which could provide the wide temperature
Differentials. In the 1930 s semiconductor materials became
Available which revived the electric cooling principles. In
The 1960 s many companies began building spot cooling
Devices and refrigerators based on these effects using a
Junction material of bismuth-telluride. Today more advanced
Materials are used with the basic parameters of being a pore
Thermal conductor but being an excellent electrical
Conductor. The dissimilar materials must provide a high
Coefficient of voltage temperature relationship. The first
Peltier devices that I experimented with back about 10 years
ago were built by Marlow Industries here in Dallas. With a
small temperature differential across the device a weak
current with an attendant voltage was developed. Increasing
the differential provided a proportional increase in current
and voltage. About 6 years ago I posted a chart of the
wattage generated from two different size Peltier chips on
the Keely Net BBS. My curiosity was based on the puzzle of
how electron flow could move thermal energy across the
junctions and how electrical energy was produced by moving
thermal energy across the junction. This is a directly
reversible situation based on polarity.
Now let us look at a very familiar parallel process used in
refrigeration, cooling and heating devices employing phase
change material such as water and refrigerants. We have
always been led to believe that evaporating water provided
cooling effects which is a mechanical process. By the same
mechanical process we are provided heating effects by the
condensation of a gas back to a liquid phase change. Would
you believe that any material that undergoes a phase change
provides an attendant electrical effect. Back in 1840
Armstrong invented an electrostatic generator based on
escaping steam through insulated nozzles which provided one
of the most powerful devices of this type ever built.
Popular belief was that this was a frictional process with
the electrical output resulting from the steam friction
passing through the nozzles. After reading an old (1920 s)
Thermodynamics in Chemistry text book I realized that the
phase change of materials was an electrical phenomenon and
not purely mechanical. The atoms of the material lose or
gain electrons in the process which accounts for the
discrepancy in the energy equation when a material
transitions between phases. More energy is present after
the phase change back to the lower form or atomic state. The
text book stated that this phenomenon could not be
explained. When Jerry and I attended a Conference hosted by
Hal Puthoff down in Austin back about 6 years ago a
Physicist from Austria presented a paper on the phase change
of water and the attendant electrical phenomenon which is
totally not understood by modern science. Now my suspicions
were confirmed that phase changes of materials are an
electrostatic phenomenon, which leads us to the fundamental
question of, What is heat? We were told in the school
that heat is the presence of energy and cool is the absence
of energy. What is the form of this energy? Let us look at
a very simple example of heating which may explain this
process. When sunlight strikes an absorbing surface it is
heated because electrons in the material are converted to
photons which are emitted in the infrared band of light
leaving the material in a net positive state or hot. The
more electrons a material loses the hotter it becomes. Now
the inverse situation is explored by evaporating some water
from the surface of a material which leaves the surface in a
net negative state or cold. Heat or cold is based on the
ion relationship in the material. When we apply a flame
(ionizing) to a material we cause the emission of photons
which is basically stripping away electrons from the atomic
structure causing a gross net positive situation to occur.
Now we are getting a picture as to how an electric current
across the Peltier junction can transport thermal energy
(ions). Since the energy is in the form of presence or
absence of electrons then it is a simple explanation as to
how the process works. All phase change processes work the
same way basically via ion transport and are not mechanical
processes which we were taught. Everything in chemistry is
an electrical or electrostatic process at the atomic level
based on the ionized state of the atoms involved.
At a Vanguard Science Roundtable discussion several years ago
we talked about the ion wind method of fire fighting in
which ionized air will extinguish a flame because of the
cooling effects. Now we see Patents issued based on
negative ion spraying of a surface causing it to rapidly
cool because it becomes net negative charged. This is a
very efficient method of air-conditioning because an ion
generator operates at very high voltages with very little
current involved. It is possible to develop this ion
transport (thermal energy) to provide direct electrical
output from very subtle temperature differentials. Remember
that this is a direct reversible process where a thermal
differential will cause a development of current and voltage
as in the Peltier device. I hope that this dialog will
provide some food for thought out there on the Keely Net.
Please provide some feedback on this very interesting line
of experimentation. Norm

Norm,
Part of your heat treatise was evaporated by yahoo, feel free to send to my email, very interesting topic that bummed me out when I hit "Would" and nothing further!
In respect to my wireless energy experiment I have found PNP to be superior to NPN, maybe they shut off faster being always on or maybe the end result is more hole ish.
