wind generator using Oscillating fan possibilities

i got this idea after playing around with my small fan I got out of a microwave what if you could use a oscillating fan for a wind generator here is what it looks like let me know what you think

    @zackthegoth i use 3 solar garden fence post lights for night lights in my house, 1 full solar charge and they last for 3 nights from sundown to sunrise, they are very bright also got them at big lots. don’t know if they have big lots where your at , but they where pretty cheap to buy.

    @Iseekoutthetruth
    thanks, I just wanted a night light in the corner of my room that didn’t use batteries or plug into the wall. That way if I wake up at night I don’t trip over something and end up destroying it out of rage.

    @zackthegoth i think anyone who can make a generator out of a fan is a good idea

  4. zackthegoth says:

    @Iseekoutthetruth
    yeah sorry about that, my computer seems to not pick up sound that well. but anyways, what did you think?

  5. Iseekoutthetruth says:

    @zackthegoth i saw your fan video, it is very hard to hear you speak in your videos

  6. zackthegoth says:

    613th viewer, try channeling the air from the ac unit. I made a fan generator too, I have a video of it.

    @blackdragoniels1 this was just a test I perform last summer, I have moved onto other test

  8. blackdragoniels1 says:

    i triend this as well but the thing is you can not reach a good voltage only about 1 volt if you put a magnet in the core.
    the fan actualy is a good one i have good results with litle dc motors where i put this fan on and also i have good results with mini stepper motors and this fan blade.
    you can easily put 10 leds to work with the right motor.
    good luck with the project

  9. Iseekoutthetruth says:

    @wewhippedemdidntwe yea your right, just wierd to see the fan working and not being plugged in

  10. wewhippedemdidntwe says:

    The fan is not actually following the air… the oscillation happens because the fan and motor are connected to gears, so if the motor turns, the swivel will happen. Good idea to use the power that’s already there (the wind blowing about, or the air coming out of your constantly working A/C) :)

  11. Iseekoutthetruth says:

    @irondmax no not yet but I plan on getting one soon than i need to teach myself how to use one, yea I thought it was a good idea my AC runs all day and all night so why not try to use the wind coming out the back. I was truly amazed to see the fan spin outside and oscillate also using no electricity

  12. irondmax says:

    its a good idea……
    do you have a voltmeter?

  13. snappy327 says:

    i have to say i am happy to see a company showing the end user how to set these systems up without having to pay for consultation. for that reason alone would make buying from these guys more attractive. i have seen a couple videos on here from end users that refer back to this company with pure loyalty. I was poking around on their site and i didn’t see the option to buy the rotor assembly. for someone like myself, i would like to buy all the parts separately and assemble them from scratch.

    Hi Sir Very nice work, I just wonder how much rpm does it take to charge a 12v car battery using same car alternator stator and magnet you used. thanks for sharing your knowledge to everyone…. (suppose i have a 70amp 12v car alternator, what do you think would be the ideal speed ??? )

  15. TheDegree777 says:

    How many rpms this pma make?

  16. OKMUNWURX says:

    Why use a PM rotor when the original will provide the magnetic field? The original allows voltage regulation : as output voltage rises, the dc feedback to rotor is reduced and so preventing further output increase ( a regulator unit is used; sometimes built in). With the PM rotor, output voltage will vary due to load and rpm. The only reason I can see for using a PM rotor would be for 100% attention free operation….Is that the reason for using a PM rotor? please email me; much to discuss

    Great videos Jeff. Excellent job of explaining several points I needed cleared up for next project. I’ve subscribed & am looking forward to viewing more ideas for renewable energy.
    Thankyou

  18. meisterjager66 says:

    The point is the cheaper wiring,less power drop

  19. nerfren01 says:

    My question is how to make the alternator turn on and off and where it should be placed (if you can get wet) and nothing happens. Also if I can use like the wind away from home and when I would need to move all the electrical things in the house?

    I Really enjoyed these video’s 

  21. jeffmolly1 says:

    @lolonghauler that depends on the stator core used.Typically they are made for wind turbines and hydro applications.
    Jeff

  22. lolonghauler says:

    are we talking 12v or 240v etc??

  23. jeffmolly1 says:

    @lolonghauler that depends on which stator and rotor used.
    Jeff

  24. lolonghauler says:

    how much power does this out put?

  25. 67tr876 says:

    @turbineguy100 Its better 

  26. tonfazg says:

    ..but with higher voltage, that would cause lower current and at the end lower power loss since here that isnt case i cant just accept what you say about power loss.
    Correct me if i am wrong, but explain it a bit, or it is something you know as a fact through experience with power transfer.

  27. tonfazg says:

    @jeffmolly1
    Power loss at the end of a wire is simply calculated with Pl=P1-P2, P2=U2*I2 at the end,P1=U1*I1 at generator output.
    Current that flows through wire is the same at beginning and end of wire…Voltage is that drops due resistance of the wire and current flow…
    Now, DC wont!! produce more voltage drop trough wire simply because it has equal power as the AC or more importantly it works with same voltage…AC would produce less power drop if you transform that same power but…

  28. PiccoloMichela says:

    This is nice, but how much energy can you produce? Can you show a video where you show the thing working? :)

  29. JWnFL says:

    How much power do you lose? if any? using a 3 phase verse a Larger DC cable / wire? is more power communicated with a larger DC wire than the 3 phase back to DC? Thanks… using you super PMA is how I would be wanting to attach, so what works best with your stuff Jeff? Thanks!!!

  30. Exasosis says:

    Nice video but how much power this thing gives ? i mean if it could give 220V , 50mhz , 3 or more kw (is what I need in italy were i live ) it coul generate power non stop for a home not only a battery…. is that possible?

  31. 2009mechanic says:

    @KC08RAS All three of the wires coming from the stator windings are “hot wires”.
    The electricity from each of the 3 “phases” is actually 120 degrees out of “phase” with the next winding just like how a 3 phase electric motor is wired.
    I believe the the windings are configured in a “wye” configuration just like they were originally from the factory.
    You cannot hook a 3 phase motor to it as the 3 phase is “wild” and motors don’t like it much .
    That is why the rectifier is needed to convert to Dc

  33. chrishorabin says:

    Just for clarification.
    DC has less losses than AC.
    DC losses are resistance (ohms)
    AC losses are impedance (Z) (ohms)
    In the alternator the rectifier is also a voltage regulator, in older alternators the regulator was seperate.
    The reason it looks like there is less loss with AC is because the rectifier/regulator is close to the load (battery) and so the volt drop is less.
    But all in all this is a very good video. keep up the good work

  34. chrishorabin says:

    Just for information. AC power has more losses than DC.
    DC losses are resistive only. In AC the losses are capacative reactance and inductive reactance and resistance.
    The other point to remember is that the rectifier is now out of the alternator and so has no cooling fan.

  35. CalicoatMaker says:

    @BudsMoKing eh? The rectifier turns the AC into DC. What are you asking?

  36. jeffmolly1 says:

    @VOODOO74W that is correct voodoo74w.

  37. VOODOO74W says:

    Hi jeff great videos I had a question or two. When you connect the stator core wires with the three phase jack wires you really don’t need to connect it to the rectifier in the pma right, it’s just cleaner? You could actually just take the rectifier out of the pma and just have the wires connected but they would be loose right? Once you have that rectifier out of the pma you can use it to change the three phase AC back into DC?
