Home made Efficient Electroplated Thermocouples
« on: February 15, 2010, 09:27:53 AM »
by setting up two different electroplate baths of dissimilar metals, one can electroplate for example, Cu, Ni, Cu, Ni continuing this process hundreds or thousands of times until enough alternating dissimilar electroplating is accomplished, each dissimilar layer between 1 and 10 Microns in thickness, the more dissimilar layers the greater the voltage, the volume of the surface layers will determine amperes when exposed to a heat source and will generate electricity.

although it would be better to use dissimilar metals in accordance to the dissimilar Electronegative properties.

electroplating is a very good technique for making very efficient thermocouple and or thermopiles for generating electricity from heat and should at some point be more efficient than standard Peltier devices so long as the alternating layers are thick enough has a whole.

using the Electroplating technique one could make rather large thermocouple plates very easily.

New idea (!?)

electrolate this way. an 1mm copper wire or thiker iron wire..
Heat up the inner wire wizh low volatge (higher current.

coling the outside. (fan or water)
so you invert the voltage to higher voltage
with thermotransformation.

Just an Idea from

Voltage is easy, current not so easy.

With my peltiers i cave current !
.
i think  also with this elecroplating , you will find "current",
because you have an great surface - layer-to layer!
Pese

BUT !!:

This idea held an Error

This can only work on one layer. !!

A Multilayer can not work because
every  EVEN and ODD layer must have a different temperature.
So its us used in any serie connected peltier elements  that i have seen to produce voltage (and power) to drive TV-Sets !! (50 years ago !!

it is true that Electroplated Thermocouples would need a temperature gradient just like a peltier, one side hotter than the other, thermal gradient travels to the 'cooler' side, the temperature would be different at different depths of the plated material do to the thickness and volume area and differences in temperature on both sides. Heat likes to take the path of least thermal resistance. thermal N,P,N,P is still the best route.

the cool thing about Electroplated Thermocouples is that they can be made easily and cheaper so long as you make your own plate solutions.

Yes. easy
AND
with great surface, also an lot of current.
You will look to find an solution to contact them in serie .
and  that each N (or P) is coller than the other .
(like hundreds squared mirrors that can used in sunlight.)

outside "black" so it can thermal heat up one side


BUT:

i am not so sure , beacuse the plate surface is thin !

and  ...
heat one side and cooling the other side ?

loök to test this out first !!

agreed, I am working on some plate solutions, the type of plate solution is going to be the most important, I wish I had Plutonium available because it makes a good host for this type of technology in that 9 kg of Pu gives off a lot of heat un-moderated, 10kg of Pu is critical mass.

thankfully I took Chemistry.

I think the problem is
to produce an temperature difference between both  outsides
of the thin-film, electroplated layers.  (if oneside is black ...(?)
 you will try it
