To me this is product is like the conical bullet in 19 century or faster than light travel in the 23rd. To be able to cool anything with electricity at a such a small scale with power and no pressure/gasses needed is a miracle that should be further developed. I’ve bought this as an aquarium water cooler and was able to power it with a solar generator and a liquid cooling pad for my sleeping bag during the day and heated water during the cold nights. For someone that lives in a humid climate, I find this tech revolutionary. Would love to invest in making commercially available water cooling/heating systems for all applications.

THANKS!!! Thanks for the education!!!!!! Question: if I mount one of these....Peltier Device to the back of solar panels, to harness the waste heat (and try to cool down panel), does that mean I have more energy from the system? How large can a Peltier Device be?

[@ElectricalPro]

Hi, Good question. I also have thought about this... I am not an expert on this, but I think yes, you will get more energy. It doesn't matter how large Peltier Device can be, because you can connect them sequentially (as many as you want). But it probably will be very expensive and not worth it. I guess you will get an additional 1% or 3 % of energy... but it is just my guess.

Hi Johnny. You can't really "hook up" the heat sinks, they're just to dissipate the heat. And they have muffin fan bolted to them. The part that got -8 and frosted over was the aluminum Cold sink that penetrated to the inside of the box which had 2 smaller muffin fans to move cold air. I had both Peltier and the large fan hooked to 12V, and the heat sink was really doing it's job and was very warn. @Johnny Buoy

Hi Johnny . The muffin fan draws very little, maybe 1/2 amp and the Peltier I believe draws 5 amps, most are 50-72 watt. KL@Johnny Buoy

[@shillout7270]

It's a pity the Hot and Cold sides are sooo close. It defeats the purpose to a large extent. Even if they were 6" or so apart, you could do heaps more with it.

[@melkiorwiseman5234]

"Can this be used as a CPU cooler?" you ask. *yes, but* is my answer. Yes, but you then need an even beefier heat sink and fan on the hot side of the peltier effect device to remove all that extra heat which it grabs away from the CPU. Yes, but you'll possibly need to replace your computer's power supply with a larger one so that it can supply the extra current needed by the peltier effect device (close enough to 5 amps for a 55W device at 12V). Yes, but it probably won't provide any significant performance increase when compared to existing cooling systems designed for overclocking your CPU. Yes, but it might not be able to grab enough heat from your CPU fast enough when compared to a simple heat sink, leading to your CPU overheating anyway. There are good reasons why it's not already done that way.

this has been done alot over the years (first in 2007 i think). you can even get a cpu fan/heatsink combo right now, it just sadly isnt great for PC cooling (or cooling over all). imagine a tec as an old light bulb (the brighter it was the more heat it made) the more "cooling" or the colder one side is the hotter the other side gets. and it also cost alot to run it (seen it taking 400 watts in one pc. just to cool the cpu)

Avaxar I understand the principle of energy and you cannot create it from nothing, my point was as we're making so much heat energy that we need a heat sink - maybe we can harness that waste, so let's say 12 volt goes in and 80% is waste (abouts 10v as heat) and we can get back 20% of that (2v return) so that means if we add it back to the system we're only drawing 10v cause we're turning partial excess heat back into electricity, Or, is that not how it works?

If you use it as a cpu cooler make sure you have a proper seal between the CPU and the cold side. Don't overload the thermal paste but do make sure you've no gaps, otherwise if you live in a place that gets high humidity you could end up condensing water vapour onto your chip which will not end well, also it should be powered off the CPU fan connector on the board which will feed it voltage as needed depending on the CPU temperature rather than having it on 100% all of the time which could also bork your CPU.

I've tried this, it works, but not like one might think. It cools it down, at one point I got to -12C while idling, but when the CPU begins to warm up, it loses a lot of efficiency and temperatures spike, higher than it would be without the module. To make it work properly, you would need more of them, I would say at least 3, in parallel to ensure sufficient heat transfer, then connect them to a heat exchanger and then to a water block on the CPU.

Do you think you could make a device that would keep a small ice pack cold?

The ice pack is so cold it numbs the area, but within about 30 minutes, the ice pack thaws out and the pain comes back just like it was, before I used the IP on it. I injured, (broke) my back almost 18 years ago and Its given me trouble ever since. I was self employed and I had good insurance, but the neurosurgeon was afraid to do an operation. I think he was worried that it might make it worse. After looking at my x-rays and MRI my family doctor said the state law prevented him from writing a prescription for the kind of medicine I needed, so he referred me to a pain management Dr and he tried everything he could, but nothing helped. The only thing left was pain meds. and he giving me the strongest thing he could, until the government changed the drug law's, which stopped him from prescribing that type of medicine. Besides my back being all messed up, he said I had degenerative disc desease's, which basically means my back won't be getting any better. The older I get, my spine will be slowly deteorate, I guess, until I'm no longer able to get around. So that what's I got to look forward to. If you could invent something like that, I would appreciate it very much and I would also be glad to pay you for your time and materials.

You can use it, but it is not worth it. Peltier module does not create cold out of energy. It just transfers heat. The heat substracted from one side goes to the other side, and needs to be dissipated. Once it is not dissipated enaugh, it will stop transfering heat, and "cool" side starts to became hot too. Having the fact, that the transfer is not 100% efficent, you will end up with more heat to dissipate.

You can do this in reverse and have the hot and cold side generate electricity instead. If it gets hot and cold really fast it uses electricity a lot. Likewise on the flipside, it takes a lot of temp difference to create electricity. So you can convert heat back into minor electricity by directing heat out of a PC case to a radiator, and have one side get hot from that, and get cooled by the other, and connecting the wires in opposite polarity so it turns temp into energy.

[@arronnunez7230]

does it need to have contact with water for the water to cool?

[@AnkitKumar-bn4cf]

Great video... What is the thermal base you are using? And what is it for? Cn we do the experiment without thermal base?

[@dolandarc]

could the walls of fireplaces in poor countries homes be lined with these to make electricity to charge batteries for night time lights? leds ect?

[@naimgorgani953]

What happens if we connect a bare peltier? (without heat sinks on neither side)

[@AdvancedEngineeringTutorials]

Could you please let me know what you are using for temperature logging? hardware and software. Thanks

DS18B20 sensor + ESP8266 with custom firmware (it is just like Arduino).

[@leonardoferrario9573]

Did you need the heat sink when you hear the cold face to create electricity? Or you could doit whiteout?

[@ghislainriou9560]

Did you try use it on a CPU to see the prolong use of it?????????

[@nicholaslandolina]

Will it make electricity on the cold side too

[@ElectricalPro]

Hi, what do you mean by "on the cold side"?... you just need to make one side hotter than another. You can also switch sides, then the electrical polarity will switch as well. If both sides have the same temperature then it will not make any electricity.

Nice vdo of some unheard technology, Can it be used as an air con in tropical countries to save electricity? How much electricity required to make one panel ice cold?

[@ElectricalPro]

Hi, yes it can, if you use a lot of them. But it is not energy efficient, I think a regular air con is a way more energy efficient. Although one side of this device gets cold, another side gets very hot, which requires cooling... It consumes about 50W.

How to power the peltier? And how to test for the hotter side and cool side before powering up? Can anybody explain plz.
