Homemade Hydroelectric Generator

This video project was made for AP-B Physics class. We built and demonstrated a hydroelectric generator and explain the process of how it works and the physi…

    hi can you tell to me what is the value of the diode did you use and also the transformer.. thanks

  2. Earl Co says:

    the diode is 1N4003 from radioshack I think. the transformer is a 5:1 step up transformer pulled from a spare power adapter. You can also pull the bridge rectifier circuit from the wall adapter, but I wanted to make my own.

    hahaha I love that your intro song is the b52’s rock lobster!

    here’s a simpler idea:
    – take one electric motor from radio shack, an old cassette player, etc.
    – put a propeller on the electric motor
    – connect a consumer(led, etc.) to the motor’s connection pins
    – put the propeller in wind, under water jet or simply spin it and enjoy the magic

    The real stuff is when you can get the real energy to power a whole village.

    In my younger days, I have climbed a few mountains looking for rivers at higher altitude, supervised contractors building small weirs, lay pipelines to reach a small power house at lower altitude downstream. Real turbines up to 2 MW.

    When I retired last year, those mini hydro stations as they are called, are still producing energy for the company.

    is it a single or 3 phase generator?

  8. Earl Co says:

    As the coils are connected in series and evenly spaced, and there’s only one single series of coils, this is a single phase generator.

  9. Earl Co says:

    Haha I love that you know the title because I didn’t.

  10. Earl Co says:

    A motor is merely a generator run in reverse, so yes that will work, but it’s not the same as building a motor, to satisfy the requirement of a science project made with household materials. Also, there’s something about the inefficiency of a motor for GENERATING electricity because a motor is designed to convert electrical to mechanical and not the other way around.

    I rarely sig in here at YouTube, but I just had too! GREAT JOB GUYS!!! Keep up the awesome work and experiments. It’s these little ventures that will help all of us have a much brighter future. Another thing is, these methods are nearly clean energy.(Most all electronic components now-a-days contain/have environmentally unfriendly portions to them. Can’t really be helped.) It is cleaner energy however though.(smilz)

  12. mcclaints says:

    Also, I think you might already know, you may be able to achieve greater RPMs from your turbine using “Pelton” or “Tesla’s” designs.(Lester Allen Pelton and/or Nikola Tesla.)
    GREAT WORK! One day in the near future, I’m a firm believer that it’s these smaller scale experiments which will lead to everyone on this planet having access to “life-sustaining energy”.

    is it posibble to make the hydroelectric gen into 3phase?im working on a project which need to construct a 3phase generator. im confused about the wiring at the coil if i want to make it into 3 phase

    Хуйня !

    Wait, so how do you know whether the magnets are placed in north and south positions? Like, how do you know how to place them properly? I really need you guys to answer this, so if you could be so kind as to respond, that would be awesome.
    Thanks!

  16. Earl Co says:

    Well, they all attract each other at one end. Put them close to each other and mark one side north, the other side south. Determine the other magnets based on what you marked the first one was, knowing opposites attract. If you want, use a compass to determine whether one side is north or south.

  17. Sofia Rehman says:

    Okay. Uhh I have a bunch of questions though because we’re trying to do this for a science project, sorry if we spam your video.
    1) What did you attatch the plates to again, in the beginning?
    2) What materials did you guys use for everything?
    3) Can you sort of re-explain how to make the rectifier(?) again please? We got sort of lost there.
    4) Any tips? xd

    So sorry for the bother! Thanks–

    Does evil twin have better handwriting?

  19. Panayiotis Panayiotou says:

    whats the size and streght of the magnets?
    whats the size of the coper in mm?

  20. Sofia Rehman says:

    Please respond! I really need this information!!

  21. Earl Co says:

    I did respond…

    It doesn’t matter. Get neodymium magnets from a hobby shop.

    Great video, funny comments too. Hope you guys both got As
