Turn a ceiling fan into a wind turbine generator?!

A ceiling fan looks similar to a wind turbine, so one may wonder if it can be used as such. Most ceiling fans are induction motors, that don’t generate electricity when being turned. You will have to add magnets. That and many other points are dealt with in this experiment. The goal of this video is to learn how stuff works, and to help everybody who wants to try this conversion themselves. I hope you can learn from my experiment, and make a better version.

  1. What you have really done is provided "Proof of Concept" and you make it easier to visualize how I would work with, or improve upon your system. You have not failed You now have a road upon which you can travel and do even more.

  2. There is nothing free in this world genius Giesbert. Although someone may find something in the trash, it still cost them time, effort and probably fuel to retrieve the item from the garbage. Don't forget about the risk involved…that's associated with a cost too. NOTHING is free in this world…everyone needs to get that through their thick skulls.

  3. I'm working on a version of this myself, will have to modify the rotor to accept the magnets, and change the winding configurations, but I'm anticipating good results. Thanks for putting me on to this idea!

  4. Thank you sirπŸ™πŸ™πŸ™πŸ™πŸ™

    You taught me all the important topics that i didn't learnt in my engineering.

    All the knowledge are practical and the important instrument mention here are available in the market.

  5. MY first thoughts …. use a big capacitor with at least 2x the output voltage rating OR use a bank of caps.
    The other 3 motor ideas sound good, I've heard a printer paper advance motor is good
    Certainly those 3 you mentioned would put out more CURRENT
    STICK to 12.9 VDC as that value is the most useful, or possibly 24 VDC

  6. Hello, I like Science and Technology. I like going to Muesems etc. Sadly I have Special Needs /Mild Learning Difficulties, so I'm not how to help you myself! Do you have any family or friends that are Electricians, Sciencetist or/& engineers etc?! I was interestedand impressed with your atempt. It has also been advised that, we need to reduce, reuse and recycle. Also use renewableenergy. Maybe you could go online, to Libairies, museums etc. Very good luck! Thank you and Good Bye

  7. I would think to leave this generator output AC current as far as possible. Stabilize and clean your voltage at peak output 120/240v-50/60 Hz. I would use a AC transformer and voltage regulator. Then perform DC voltage change to batteries. However maintain AC feed to appliances that have proper conversion cords (wall chords) maintaining AC as far as possible avoids the heavy DC voltage drop.hope this helps.

  8. Instead of a ceiling fan try your project with a old automobile alternator. You don't need to add a diode or bridge rectifier since the alternator has the heavy duty diodes self contained. You could add an adjustable voltage regulator to power any dc device from about 14 Volts down to 1/2 Volt if you want. Another regulator that will work well is one made for solar panels.

    Good luck with all your projects.
    ps: I'm a retired communication tech (mostly microwave radio background).

    On another front, I've built a project that will give me 38VDC that I feed to an adjustable regulator that allows me to feed a load as high as 35 Volts DC and adjustable current limiting from 15 Amps down to 1 ma. I typically use it to charge an automobile battery to 13.5V. The battery is in a battery box that I hookup to my amateur radios. One feed to my Alinco HF Radio or to my Yaesu VHF radio in my vehicle. This battery is completely independent and not connected to my Hyundai Ionic Blue Hybrid (gas + electric) car. Gas engine is 1.6 liter displacement and electric is 23 kilowatt fed from 240 V battery bank under rear seat! gas mileage averages 4.4 liters / 100 km. (works out to about 65 miles / gallon)

  9. You fill the gaps the same way you did with the other gaps. No need to rewind the coils, just cut and wire coils in parallel. You double or quadrupole the amps but retain the voltage. Thus, you can run more power as you have 2x to 4x the wire thickness, per N/S pair. As opposed to having one long wire and thin wire. I am sure it is already setup into two halves anyways. Since it is AC already… Just use a simple transformer to get the voltage down to 12vac, then use a better auto rectifier from a high amp alternator. Or… Bump the voltage up to 120v Max and use a standard low amp home voltage rectifier or simple voltage regulator. If you have a circuit that just dumps excess power to a shunt load, then tap into that and put that excess power to use. Motor cooling, an accessory light, another battery bank or a small heater. (A physical break for the motor or blade tilter, to add self regulation without additional circuit or generator stress.)

  10. I would love to know the true output values in volts watts and amps as this could be used in other ways than juststicking it outside in the wind i.e. imagine the ease of this lets say made to crank with your feet a small tv runs at about 45 watts you i control ing your feet of hand better than the wind a family could have one of these each imagine watching tv and earning it or any other fun and games we live in a world where humans are destroying it mostly burning and making gases so we can sit on our backside watching tv or pc. make a cap bank you need a few to get is nice and smooth storage type are best, best ideas come from the I wonder if guys, I personal know you can get aa lot more out of that fan tinkeraway but always be safe something cranking up in the wind can kill you very easy p.s, I made one like this 25 years ago remeber this also power travels better at AC SO IF ANYONE IS THINKING OF PUTTING THIS OUTSIDE CONVERT the ac as near to the batt bank as poss as you will get heat loss if you dont

  11. Giesbert, you are a very good instructor. You have a pleasant voice, talk slowly and concisely. I know less than you claim to but have a general knowledge of electricity but none of the electronics. I look forward to seeing your next video and will follow you thru your journey to build a proper generator.
