Hi mr welander I'm an ac tec in tx and my hobby is renewable energy I have a question about your video if I add more heat and extened the surface of the thermocouple would it be practical to recharge a battery bank with and how big do u think the heat and thermocouple would be I look forward to hearing from u plz email at smith.marcus.t@gmail.com thanks for the video
my physics professor had a nifty gizmo he showed in class, it used the same effect ; heating dissimilar metals to generate voltage. it was a copper bar wrapped around a 3/4" thick 2" diameter steel disk. both ends had large (1.5^2")plates, (didn't get a close view) but since the copper wrapped about 350 degrees around the steel disk, when he hit the plate with a torch, he produced an electromagnet that held up 8kg and i've been searching the web to find it. when it cooled the weights fell.
this is really easy to understand because it has visual aid, straight forward and simple.. usually in a classroom, you only see letters and mathematical formula.. i think it lacks attraction..hence, students become bored and the understanding of the idea is lacking..or maybe they just care about exam and not practicality.. haha "better known as my basement" a good one..
if you wanted to make it more efficient you would make layers of alternating copper and copper/nickel about 10 microns or less each so you end up with thousands of thermocouple layers.
The usual way of converting voltage to temperature is with a table. These are available online and in reference books for all common thermocouple types. The ice simply provides a known temperature reference. Most thermocouple charts assume that one end of the wire is at 32° F, so the temperature difference is in reference to that.
A thermocouple can only measure temperature differential between the hot and cold end of the wire. Using icewater establishes the cold end at 32° F so you can calculate the correct value for the hot end.
This video really helped me a lot in understanding thermocouples. I was having difficulty understanding thermocouple in wikipedia. This video is really useful. Thanks and keep up the good work.

i have an idea on how to use it as a constant power source but i need your opinion on it if it might work?

thanks for teaching us... can we generate 2 to 4 volts from temp not more than 60 degree's and if yes then which typ of thermocoulpe will be used ?

Love it. how do you calculate the temperature from the voltage reading? How is the ref. junction (ice water) used as far as mathematics is concerned?

Nice presentation. It might be even clearer if you had the elements on a white piece of paper or a solid color surface to make the easier to see.

how dose the ice water work as a control, wouldent it act like a resistor being cold? If so is the tempreture of the ice water the known vareable?
