This is NOT a peltier element.
The capacitor is soldered together by 88 pcs. 10uF / 16v type Y5V multilayer nanocrystal capacitors.
Altogether 880 uF at 25C / 77 degrees Fahrenheit.
Heated to 50C / 122F the capacity is only 100uF.
Start with a cold capacitor. Charge with + on the bottom and minus on top, to 14 volts.
Now there is energy in the capacitors, without green Led lights.
The zener diode is 12 volts and the green Led is 2.8 volts = 14.8 volts
When heated, the voltage rises to over 15 volts and LED lights. Can light for more than 8 minutes. - Наука та технологія
Whoa!!!! is this how peltier coolers work?
Nano crystals...awesome
This is a demonstration of conservation of charge. When you apply Q=C*V (charge displaced in capacitor = capacitance times voltage), and then lower the capacitance by heating the very non-temperature stable dielectric, the only way the same charge can be stored across the lower capacitance is if the voltage rises inversly to the capacitance change. Any other means of changing capacitance (like changing the spacing of an air dielectric capacitor) does the same thing.
Here is the data for a Y5V capacitor that shows the capacitance falling to 30% of its 25C value at 85C, so the voltage has ot rise ot 333% of the 25C value.

Damn cool!
You can also just use 3 to 5 LEDs in series then you dont need the Zener Diode !
Yes, 3 to 5 LEDs can also works. You have more light with one.
I now that LEDs are not so sharp in the volts, as a zener diode.
The bias voltage should be almost as high as the capacitor can withstand.
How did you solder it to these plates ?
Are these lead plates or what kind of plates ?
Can you show it how to solder these things together ?
Hola como estas, una pregunta con que material esta echo en el centro? como lo hicistes? saludos muy bueno
Why don't you choose this Y5V capacitor idea into some usefull stuf omong other trivial subjects insted? I think, it can harness embient heat if combined with stirling engine up to 100%(in ideal, there is no teorical limit ) . ı would be glad if I can help.
Well done...!The question is , if this can repeated over and over without recharging the capacitor...So can it work like a peltier element ?
No
Larskro
So how could the cycle be repeated ?
Do you need to cool it down and then the voltage would be how high without the LED ? Do you need to charge up then the cap again to 12 Volts and restart the heating again ?
Could this be somehow adapted to solarcells to capture the heat from the sun when solarcells heat up and thus also use the waste heat on solarcells to generate more electricity ?
Larskro @Larskro Appreciate the work that you share, your videos provide some very good learning opportunities. This is a very good demonstration of how molecular properties of multilayer ceramic capacitors are affected by heat. The ceramic Y5V capacitors have a -20%/+80% tolerance, their capacitance can be affected by heat and/or DC bias because their permittivity is not stable over a range of these two factors. When you apply the heat you are decreasing the capacitance which increases the voltage but you do not gain stored energy. As you state in this video, you have to recharge the capacitor to repeat the process.
I think a decrease in capacitance is also taking place in your recent pulse motor/gen videos via a DC bias. The pulse motor runs a very long time because your finely tuned motor is extremely efficient and can run at a very low voltage, and you are also charging a high 0.47F capacitance. But I think your pulse motor will eventually stop when the stored energy is slowly consumed by it.
Your pulse motor is a very interesting and clever demonstration where I think a DC bias applied to the multilayer ceramic capacitor is playing a role in decreasing its capacitance and increasing the voltage resulting from the magnetic switch pulses. It is also a good demonstration of making use of stored energy that would be wasted if the voltage was not increased by this method. There is still a question in my mind whether the ceramic capacitor piezoelectric affect is playing a role and I plan to experiment assuming that you have provided an accurate schematic.
Thanks for sharing your work and effort, I've supported your objective in the past. By now you must know, does your pulse motor eventually slow down and does it stop on its own after an extended run time?
overunitydotcom I have soldered all Cabs on a brass plate. It's not easy.
It is my plus side.
The top end of all Cabs are solder. Here is minus.
Select a zener 12V + green LED 2,8 volt = 15 volts bias,
or 3 pcs. white LEDs = 9 volt bias, works too.
Start with cold Cab.
Charge the Cab to the bias voltage.
Then heat .... use a soldering iron. The LED lights up. After a while the cab is empty.
Then be cooled down, and is now ready for re-charging.
I can not explain how electric spikes affects.??????
ReasonForemost Thank you for the excellent description.
I can`t explain how electric spikes affects.??????
Awesome, you did it! thanks, now i know it will work and my 100 set have come today =D. do you actually need to have a diode in there, isant an LED a diode too?

peltiere no mystery. your hand is the negative pole.

now you just have to combinate with peltier batteries...
