The idea is that oil you used for cooking and now you don't need anymore, can be used for lighting.
Not super bright but it's a very prototype and for emergencies it's enough.
HOW IT WORKS:
Heat from a candle goes through the Peltier module into the pot. That produces electricity. And because we have just one flame and the voltage is about 0,6 ... we need something called "Joule Thief" to light up an LED with a proper voltage.
You can connect even ten diodes at the same, place them here and there and they will all work (but,best to use switches)...kitchen, wardrobe, pool, bathroom...whatever you want.
No batteries, just one little flame.
....and that's it.
The whole generator is portable and it's not that hard to make. Internet is full of instructions and tutorials for thermoelectric stuff,you should see that before you start doing it. Mine isn't so stable.
So ..what i've used:
Peltier module (they are used in computers and ect.)
solar garden light (in..a gaden shop propably)
aluminium heat sinks
used cooking oil
LEDs (must be white for best results)
aluminium "cup" from a candle
any short cup
toothpaste (or thermal paste)
steel building blocks
*These pictures are much darker, like in the first one you can see just
the sink, but really you can see the whole room and orientate in it with no problem. And that's just one diode.
