    merci beaucoup pour les élèves français en classe de collège. C’est vraiment un travail de professionnel.

    YES, im so glad a science youtube channel is the most subscribed, makes me feel better that a lot of people like science.

    dude those windmills are like 45min from my house

    I think force is =N*9,8 and that is =Kg. (in Spanish: force= masa * aceleración)

    F=0.9N*9.8 –> F=8.82Kg.


    P=22.05J/9sec –>P=2.45Wats

    Perhaps I’m in mistake, I’m not sure :).
    Is thrue i’m in mistake, 8.8Kg of coins is so much.

    my x boy friend built wind turbines..they are huge..hazardous..but it is really beautiful to see them all working..

    thanks for your knowledge

    W=F * s

    And P= W / (delta) t

    nice videos
    you kinda look like red from that 70’s show

    Very interesting and instructive video.
    I suggest you to product more others similar.
    You use very good mix (audio and video), and everything is very understandable…, also without audio.

    best explanation ever

    Thanks for the video…!!Love to see the power calculation done through simple means…!!Also the simple way of making a turbine…!!

    i think that this helped me a lot. i ued to not like science. now i find it interesting and fun since there are so many ways to experiment to determine the answer. 🙂 THANKS FOR UPLOADING! =)

  14. SuperDears says:

    i dont understand how do you make energy with that ?

  15. Auslander999 says:

    The one question I have, how does a prop spinning on its own generate any power without the generator? And not too mention the gearbox and brake system that can increase or decrease the speed of a wind turbine.

    Or is this an example of how engineers determine what size prop is needed to turn a generator for optimal efficiency?

    well thx this helped with my science project

    Omg I wish this guy was my science teacher!

    Thank you for the informative video. I love the pinwheel design A friend of mine built a gigantic one out of metal. bonehome in my list. i will show him this video. Good luck and Godspeed Sir.

    Great video, very good explanation, thanks

  21. lowhigh0 says:

    thanks,nice video!

  22. acclivitous77 says:

    Fastastic video, great narrator… Well done, very effective knowledge-beacon! 🙂

    15 people there are more intelligent than this person…


    can it be any kind of paper?

    hey.. what is the size of the wood?? for the base??
