Hiiii
They were one of the coolest devices when i was a kid. Too bad the efficiency is low. Using Vapor Compression Cycle is much more efficient even if they're not solid state. Good video 👍👍
Great video. But why didn't you include the cooling effect of the cold brine solution in your calculation for efficiency?
Nice. A friend made a datalogger for smoke stacks that used TEC temperature differential to keep it alive.
It would be interesting for this application to be explored on super low temp research vessels.
While watching the video I started thinking about if it would be possible to combine a bigger array of peltier modules and a joule thief, and just utilize the temperature difference between ambient and wet bulb temperature, to maybe charge small batteries, extremely slowly, not if it would be practical, but if it would be possible without an insane number of peltier modules, and then you mentioned efficiency, that made me laugh.
Great episode, even if I think the energy represented by the ice should have been included in the efficiency calculation, as it is the difference, not just the hot reservoir that represents the energy source.
Seebeck Device? 🤔
Danke Ihnen DENKI OTAKU für das Video.
Zwischen der oberen und der unteren Keramikplatte sind nicht nur die aktiven Seebeck-Peltier-Elemente angbracht sondern auch zwei thermale Kurzschlußzonen. Neben den Aktivzonen könnte ein Vakuum den Gasflußkurzschluß der Wärme reduzieren. Bleibt der Strahlungskurzschluß. Also benötigt man dazu noch eine thermische Rückspiegel-Diode welche verhindert das die Bolzmann-Strahlung der warmen Seite auf die kalte Seite zurückwirkt. Zwei Lambda 1/4 Doppelschichtspiegel, für das thermale Betrtiebsband ideal, könnten dies leisten.
Diese Maßnahmen könnten bei gutem Seebeck-Wirkungsgrad sicher zu einem respektabelen Resultat führen.

I LOVE THIS CHANNEL
I expect more from your channel than some two bit Peltier module video.
Interesting video.
Are Peltier devices used commercially? what is their use?
Thank you Denki 🙏🏻
There is video of a guy that insulates one side snd creates energy from temperature oscillation of the environment.
0.6% is actually quite good. Great job!
You can achieve 2-4% at best but that requires a very high delta temperature and insulating all paths.
Which thermal camera are you using and would you recommend it?
07:33 🤓😁😅😂
thank you !!
Great video! I really enjoyed watching this, and it gave me some ideas for experiments to try. Greetings from the United States.
素晴らしいビデオです! 本当に楽しく視聴できました。実験のアイデアもいくつか思いつきました。アメリカからご挨拶申し上げます。
What are the most effficient peltier devices? I was thinking of researching a drink cooler using a small solar panel.
IIRC this is basically how deep space probes are powered. Instead of candles, they use a chunk of plutonium as the heat source.
what solar pannel is that ? and how many watts . thanks maybe a link
Does a single candle really produce 30 watts like in his calculation? I would have expected something like 5 watts maximum

Of course, at 10:00 you can put a blade on the motor and use it to cool the system instead of the ice bath giving unlimited* power.
* may not work as expected afterApril 2.
You are one of the few who do science on YouTube 👍
I hope you used TEG for generation, not TEC.
Awesome! I love this stuff after a big Joint Greetings from germany
Congratulations on the video and excellent explanation of the experiment! I also saw the previous video where you used cells to cool and I’m curious…Have you ever tried to use cells for heating? may be that their efficiency is better than a classic resistance
