THERMOELECTRIC MATERIAL
« on: September 24, 2018, 05:30:45 pm »
Hello,
Please guide on the most helpful part thermoelectric material play and what are it's future scope and recent invention that make our world better in the solar field.

I want to know more deep on it. Is there any good study material.

I don't know about thermoelectric and solar but if you want to get a fewl for it,  take a copper and nickel plate, touch them togeter,  put a deltaT on them  and measure the voltage on the opposing sides of the plates. There you go...thermoelectric. Or just buy a Peltier device. 5 bucks on ebay.

Judgind from your initial post,  maybe start off by searching 'thermoelectric effect' on wikipedia and then go for the references there. Should get you feeling all ...ahem....warm and fuzzy reading it.  Sorry,  couldn't help it.  :-DD

Man.I think someone misguided you like most Indians often do.
If there was a holy grail solution, every multimillionaire company would have implement it.They have the money but they have run out of ideas, and are thus simply copying each other, taking out headphone jack, adding cameras etc.
Apple had excess money, they invested it on solar and might look into selling electricity in near future.

Please just stick to simple solar panel for now and don't think of making anything s#itty. It makes all Indians look bad.
Unless you know a lot and have a scientific laboratory and ability to discover/invent new phenomena.

Btw, there is teg (thermoelectric generator chips) which turns heat differential into electricity,
there is tec (thermoelectric cooling chips) that pumps heat.
Both are very inefficient.

But if you really go into it, i'd recommend this video (warning:foul language)-You see,it needs 500+ degree centigrade of temperature difference to charge its battery,which is then used to charge the phone.

If you really wanna be a technical messiah or something. Start smuggling the 80% subsidized solar panels, Punjab government is giving out to Punjabi farmers.Or import cheap electronics from foreign countries like USA, China etc. Specially China. import them, open them to give them some final touches to extend their lifespan and sell em.

Its a harsh world out there. You need to be equally harsh

Stirling Engines have traditionally been efficient converters of 'low grade' heat. They would certainly better the efficiency of thermoelectric and quite possibly rival solar panels for the right application. With the availability of low cost mechanical engineering facilities, they may be an interesting line of investigation for you.

Arizona style of molten salt- electricity generator is the way to go I think. Sterlings are hard to maintain with multiple fluid seals.
But the OP, I think can do neither since the land is extremely expensive in India.
