5. Conclusions
The results conclude that there is voltage produced when copper and
constantan is submerged in ice and boiling water. Although the voltage
produced is small, if the temperature difference is great enough, the amount of
electricity produced would be enough to sustain human life. This way, we would
not have to rely on burning fossil fuels to generate electricity.

5.1 Practical Applications
Power generators → Co-generation using Seebeck effect has been proposed
and applied by many power generating units to utilize the waste heat generated
in the industry to produce additional power. Another application is radioisotope
thermoelectric generators which are used in space probes, which has the same
mechanism butuse radioisotopes to generate the required heat difference.

Thermoelectric generators → Thermoelectric generators could be used in
automobiles as automotive thermoelectric generators (ATGs) to increase fuel
efficiency. Another application is radioisotope thermoelectric generators which
are used in space probes, which has the same mechanism but use radioisotopes

5.2 Areas for further study
The spin Seebeck effect. Using a recently developed spin-detection technique
that involves the spin Hall effect, we measure the spin voltage generated from
a temperature gradient in a metallic magnet. This thermally induced spin voltage
persists even at distances far from the sample ends, and spins can be extracted
from every position on the magnet simply by attaching a metal. The spin Seebeck
effect observed here is directly applicable to the production of spin-voltage generators, which are crucial for driving spintronic devices.

The spin Seebeck effect allows us to pass a pure spin current, a flow of electron
spins without electric currents, over a long distance. These innovative capabilities will
invigorate spintronics research.
