Thermoelectric generator - candle and cold water

Conrad:

I agree with you 100%.  No OU of course but I like the challenge of finding a way to use these where we are already paying for the hot, or the cold.  One example a buddy of mine used it for was against his cold window in the winter, and the heat from his house inside, that he paid for anyway....he could light a large led bulb via a jt circuit and it was free.  The reverse might be true in the hot summer with the ac on.

To me, this is the fun of it....trying to find out new and unique ways to apply this technology.  It is not easy as the hot and cold sides are very close together but...with some good thinking, I know folks will find some great ways to use these.

Hi Conrad,

You are doing very good work. I like the idea of reclaiming heat that would've been lost anyway. In the winter you have plenty of snow to keep one side cold.

Maybe add a freezable cup that can be popped on and off the top. Stick a couple in the freezer, since your paying for the power already for the fridge reclaim some of that energy too. When one starts to warm down just pop it to the freezer and pop on a new frozen cup.

You could also add some solar panels and capture the light from the candles. Get high current cells, like .5vdc, 7amp cells with artificial lights you lose about 98% power. So a 7amp cell will be more like 140ma. Three panels will give you enough to charge a battery or ultra-cap to 1.5vdc.

I toyed with the idea when the power went out during the snow storm Alfred:

Well, solar panels work better when cool vs hot, so we could mount these on the back of the solar panel(hot side), and the cold side could transfer the heat to water pipe system for producing hot water.

So now our solar cells work better, we also get power from the Peltier's and hot water to boot. All in the same square area. ;] Just a little thicker. ;]

Exactly the type of thing I was talking about.  I saw a tube video last night where a guy had a 300 watt peltier and ran it from a computer power supply.....the cold side made a large blob of water into ice in less than 36 seconds.  That has to be useful somehow.
