Peltier elements ...

Peltier elements are usually crystals of Bismuth Telluride in a np junction, with the crystal doped with phosphorus for the n-side and doped with boron on the p-side to create a strong Seebeck coefficient and allow electrons to move from the n to p side creating an electrical current in response to a temperature differential.

Semiconductors are ...

Semiconductors are quite notorious for things like this, for example they exhibit Thermoelectric effect (thero=heat giving electricity), photoelectric effect (photo=light (or photons) giving electricity) photoluminescence (light of one color (or should I say wavelength), giving luninescence i.e light of another color (or should I say wavelength)) It all comes down to the small band gap they have which means that little energy is needed for electrons to go from valence band to conduction band and photons are quite sufficient to provide this level of enery for electron excitation, these could be photons from infrared radiation (which comes from anything having any temperature, which is just about everything, but it is strong from hot objects (relatively speaking)) or visible light (which is also from the electromangetic radiation spectrum and thus made up of photons). Semiconductors may not have many charge carriers under the our average ambient conditions, but a little heat or some strong light from a lamp can increase the charge concentration immensly giving us effects like the one above due to charge flow. I am an electronic engineer by the way.

For those asking ...

For those asking where you can get a thermoelectric tile, here is one available from Sparkfun: https://www.sparkfun.com/products/10080

maybe i can make ...

maybe i can make this to power my xbox 360 :D

I think power ...

I think power company's should look into this type of electric power generation like in New Zealand with the hot water coming out of the ground.

Made of 2 ...

Made of 2 semiconductors. One with excess electrons one with not enough electrons. 

Does this translate ...

Does this translate into home or industrial applications? Could I light a candle under a metal pail of water and theoretically power a mini fridge?

are the wires sir ...

are the wires sir ...part nitinol or gold-cadium ?

Where can I buy the ...

Where can I buy the peltier tile only!!!!! PLEASE HELP!!!!!

hello, I'd like to know the temperature difference at each side and how large the voltage is generated?

does anyone know ...

does anyone know what "the element" consists of? and where i can buy one from if anyone sells them?

IM STUCK HERE FOR ...

IM STUCK HERE FOR MONTHS!! PLEASE LET ME OUT!!!

What are you doing ...

What are you doing selling toys?? GO GET A PhD!!!!

they do already ...

they do already minus the power saving, its Peltier cooling, lets the CPUs go sub zero but its expensive as all hell

Thanks! but is it ...

Thanks! but is it that simple? two different metal plaques together, one hot one cold? how do i get the electricity? one cable touching one plaque and the other the other??
