peltier heat pump, turns hot or cold, into electricity !

[nitinnun]

i doubt most people know this. so it is worth posting.


i have a $13 peltier heat pump. the kind they use to cool computer processors.


with my fingers, i pressed it against the ice in my back yard.

i tested voltage, and my multimeter read 0.5 volts !

i tested amperage, and my multimeter read about 450 uA !


the peltier acts as a temperature diode.
turning "temperature", into electricity!


i read that certain hydrolysis machines, heat the water in them.
maybe i could convert the waters heat, into electricity.

The real trick here would be to build something like it, larger, with home made materials and it still remain affordable.  ..would it compare to a solar cell.

Electricity from snow is interesting - but it's still a temperature gradient that's being used.

The peltier device is essentially a thermocouple using sophisticated materials and [what not]^TM.

This is an very old invention.
Peltier have this invented as he find out
the 2 different metals give of an voltage.
so cou can build an temeratur probe (meter)
aswell power sources.
GRUNDIG have build them in End of 50's.
to drive (Grundig)-Television sets.
It was selled only in Export (i heared, to Saudi..)
This sources, was an Petroleum lamp (kerosin)
and some hundred peltier contacts was surround
the light-flame.
Do not wonder.  I tried that with and Solar reflector
one side hotted of . othe must be monted an alumin-heat-think.
(if possibel)with airfan.
It is one one solution, that can used to have "free or unpaid"
energy , it taken from ambient

Only if you have a temperature differential. That's the problem the solar cells don't have.

Take care,
