Pedal bike 12 volt power generator, dirt cheap, ghetto style

For more info: ecorenovator.org A simple, home made pedal power 12 volt generator made from an old mountain bike and junk parts for $12 (not counting stuff already on hand).

    @ProjetLESE i was about to say that exact same thing about the diode. “but… pedal faster than the motor and you generate power” seems like a HUGE waste of energy

    this has been done with altnaters as well. using the tire as a giant gear and a belt to get the 3000 rpm the altnator needs to start up it can genrate at lower rpms but they needs to be reved to start genrating. and you get mutch more power genrated.

    Get it up to 1500 watts and you can power an electric heater to help heat my house in the winter time.

    @ProjetLESE does a birdge rectifire waste energy somehow, such as in the form of heat

  5. kitchaki says:

    Good now add a diode and change the back wheel to something more heavier. Allso how many Wh does it produce?

  6. ertgunner says:

    you do realize that you can add a diode to make it way more efficient right ?

    Hello, Could I use a Dayton Permanent Magnet TENV Motor 1/35HP 2350RPM to do this? here are the specs..

    3.80 amps @ 12 Volts DC; 1/2 Inch Long Studs, 2 5/16 Inches on Center; Body Diameter 3.2″, Body Length 4 7/8″, shaft 1/4″ x 1″; Thermal Protection = None; TENV – Totally Enclosed Non-Ventilated; Continuous Duty; self-aligning sleeve bearings; Rotation = Reversible; 2M197 discontinued; 2m197; 2m272; 1lwk8;

    You might try replacing the wheel with a ceiling fan motor and drive back your watt meter by exceeding the normal motor speed too.

    Man, you should wear formally (black tie) for this demonstration, old british style.

    Magnets, how do they work?

  11. Gen4505 says:

    Ever heard of diods?

  12. NateFosterSR says:

    excellent video thanks

  13. nnnnnn7678 says:

    @EcoRenovatorDOTorg If you add magnets to make the back wheel spin by it self. Have you try that.

    That’s brilliant it’s great when people actually do stuff, well done and the music was cool. Thumbs up!

  15. leonscorpio19 says:

    @bulldoggrrr okay, that makes sense.. thanks. i still have a bit to learn on electricity..

  16. bulldoggrrr says:

    @leonscorpio19 not really ” generate more power” but actually more like waste less

  17. coachgeo says:

    us an old 12v hhand held drill as your generator

    Can you please tell me what kind of biking shoes you have? I’ve been looking for a good pair that look like regular shoes so I can start using my clip pedals for commuting, because I don’t have enough room for an extra pair of shoes in my backpack.. Thanks for the video! I am also working on a group research project for school and your video gave us an idea of where to start!! Thanks!! :)

  19. leonscorpio19 says:

    @ProjetLESE i was thinking the same thing but i’m not too versed on it. So, if he put a bridge rectifier or a diode on the system, would that mean he would actually generate more power be pedaling the same speed?

    Free energy technology exists!But there are very powerfull forces that want to supress the technology,Get a real free energy motor at LT-MAGNET-MOTORdotCOM ,Free yourself!

    @BFMEOWNZ Simple people respond to simple things.

  22. wiredforstereo says:

    @ProjetLESE Since it’s DC, a rectifier is not needed, just a strategically placed diode.

  23. 73prime says:

    Cool song it funny! nice Generator. we where thinking of making one.

  24. BjBlasterdotcom says:

    You need a diode in series with that motor so you don’t waste that produced power spinning the wheel when you stop!

  25. SgtCrom says:

    @awizardalso, It’s not practical at all. I’m going off memory here but I think you lose something like 65% of the energy you’re putting in mechanically. I like your ideas, I want to add washing machine. Those suckers use a lot of juice.
