Dave plays around with an energy harvesting kit to see how much power he can get out of a Peltier device used as a Seeback effect module to generate power from temperature differentials.
Bonus white board tutorial of how Peltier devices work as heat pumps.

    5% teg efficiency could be a deal breaker for my project. on top of it all, so far i an only able to produce a max of 400mw using my eyes and hands on a load tester looking for mppt. my max current i have seen is 300ma using copper water blocks, artic silver thermal compound and 150f on the hot side and 30f on the cold side.

    This video has helped me out on an exam today, thanks!

    I tried to build the LTC3109, but didn't work… I really don't know why. Check the orientation of the transformers, caps values, pcb layout with DRC etc.. got nothing… anyone else tried to build something like this?

    oh god am suffer

    Sounds like Transistors 🤔

    "display it for you yanks" hahahah love it

    This is not TEG.
    You are using TEC backwards.

  8. Avataaar/Circle Created with python_avatars sofia ramos says:

    Hello, I have a problem with this kit. when I put my hand on TEG1 it does not turns ON the LCD, instead only turns ON the LED 1. Do you know why»??? I just bought it like this :/

  9. Avataaar/Circle Created with python_avatars Artjoms Pugacovs says:

    TEC 150 celsius?
    Come on, show us video of 300 celsius TEG

    One question! If its all about heat flow, then nothing is really lost, so if you banked up 2 or more panels, would you get >5% "efficiency" ? I mean it doesnt matter what the temperature difference is, just the number of joules available?

    haaa, Now I can go to Mars without worrying about power shortage anymore!

  12. Avataaar/Circle Created with python_avatars Aurelius R says:

    Really? 200 freaking Euros for this kit? Wow. Give me a break.

  13. Avataaar/Circle Created with python_avatars Aurelius R says:

    It's also important to note that Seebeck was FIRST!! He discovered the Seebeck (and many speculate possibly also what we now call the Peltier effect) over 12 years before Peltier started his experiments.

  14. Avataaar/Circle Created with python_avatars Werner Schuster says:

    yeah… Seebeck-Effect… the energy-source for Voyager 1 & 2…
    (Radioisotope Thermoelectric Generator)

    GOOD MEME XD

  16. Avataaar/Circle Created with python_avatars SimoWill75 says:

    So sad that the Tek is relegated to being a simple weight.
    I'd have used the Brymen as a weight.

  17. Avataaar/Circle Created with python_avatars C2welder says:

    Does anybody have an idea for a dc buck converter than can take 0.5v 5A and bring it to 5V.

  18. Avataaar/Circle Created with python_avatars Powered by Sergey says:

    Nice!

  19. Avataaar/Circle Created with python_avatars Aquaponics - Eigen Tuin In Huis says:

    nice one got one to experiment with microbial fuel cells meaby you wanna do a energy harvesting with nature video 🙂

    It will be relatively quick (vid 1 hour long)
