Something like this would be great for leveling power levels in an off-the-grid setup. Solar panels and wind turbines give what they're gonna give when they feel like giving it.
I wonder how big one would have to be to store solar power at night for refrigeration.
Thank you for sharing. May I suggest that you volunteer to show this into a local high school physics class before they start their topic on electricity, inertia, and flywheel, Thanks also for adding that feature on safety on why it should be balanced. Your experience with Low Batt is also a message for everyone to learn from.
Huge industrial applications. Momentum is very efficient storage if you rid of bearing friction, Magnetic bearings? For Wind resistance. place the generator in a vaccuum? .
Using an axial ironless core motor no eddy's or cogging, Ultra high RPM, one can decrease the impedence/resistance load raise the output voltage and lower current demands for devices increasing efficiency and lowering heat generation. Silver for conductor windings.
The Williams Formula 1 team used a flywheel kinetic energy recovery system on their 2011 car. I was surprised how much energy can be stored in, and recovered from, a flywheel of even a modest size.
You get out what you put in , you used power to drive this up , coarse you can drive a led but will power down as kinetic energy will be involved, good luck making free power ha ha
great demo - this is one of my favorite technologies. good point that this requires precision machining. this is a limited but essential application of applied physics. I guess my favorite use would be in recursive braking energy. I wonder which requires more maintenance, a photo-voltaic system or a kinetic system. hard to say, as far as the philosophy of it.
An electric motor is also a generator. If you apply power to the motor it will turn and if you turn the motor fast enough it will generate electricity. Usually you get about 1/10th of the energy put into the motor. So if you have a motor that for example uses 12v 500mA @ 1000RPM and you use it as a generator, you will get 12V 50mA out of it when you spin it @ about 1100RPM. The flywheel is just to store the energy It takes a lot more power to spin up the flywheel than you get out. Interesting!!!
I would like to know how you managed to balance the weight on the fan's spindle. I'm working on a project that also uses a fan for the base and I tried many many ways to centre my rotor as accurately as possible - yet I can't do it properly. Any advice would be greatly appreciated!
i would like to know how did u manage to connect the weight to the shaft of the fans is it by welding or what way cuz i noticed something like a plate right beneath the weight this is a gr8 experiment plz reply
You could put a circuit in your flash light that would pulsate the lights at a high frequency (highger than the eye can theorically see) and thus save on the power it consumes.
Its a great simple video showing how flywheels store energy. I think people have to understand that flywheels only return energy for a short period of time and because of this are excellent replacements for battery technology in Un-interruptable Power Supplies and are made more efficient in vaccums conditions and with EMF added. Its good that you pointed out the drain on the flywheel (noise difference) that happens when load is applied. A great example for budding electrical engineers etc!
How does it feel to have a British auto news website linking to your video? They list your video as a good demonstration on how flywheel power storage is possible to explain the concept behind Volvo's new KERS system. Pretty cool eh? =D Great vid, keep up the good work!
but even without tapping into it, doesn't the energy supply still decrease with time? (not ideal for *storage* which is supposed to be indefinite as long as it ain't used)
magnetic levitation eliminates part of the problem, but friction with surrounding air is still an issue (unless the wheel spins in vacuum)
I'd love if you could tell me the current rating/power that this fan was originally at. Perhaps if you have a multimeter to hand you could measure the current draw at 12V?
@mattlomas I have no info on the fan, I removed the sticker and threw it away a long time ago. My flywheel is stored away among a bunch of other old projects and it may not be easy to find. If I come across it again, I'll see if I can take a current reading for you.
You can estimate the speed by watching at the synchronization of the light and the spin of this white stripe on the top of the flywheel. If I'm correct you can see the stripe still three times while it speeds up, so it means that you are a little bit over 60 by 3 times Hz (if you are in America) so it means a speed of over 10800 rpm.
Very cool demostration. Have you try to put the system within a vacuum machine. You can use one of the vacuum systems in the kitchen for saving food.
I have a 12V dc motorand I would like to build a small model of flywheel energy storage. may I know how do you connect from the power supply and the connection to the LED light? And how much weight of ur flywheel?
@The512MB I have little info about this fan. I took the stickers off a long time ago. I believe it came from and old ( >= 10 years) computer power supply. The video is not deceptive, it looks that fast or faster in person. I have even had it running faster with an 18 volt supply. I don't have proper equipment to measure rpm but some day I may rig up something to get a reading. I have even considered testing it to destruction just to see how crazy fast I can get it.
@supercaleb08 Very inefficient. I didn't do any calculations but based upon the fact that it slows to a stop in about the same amount of time whether or not I have a load connected indicates that a lot (probably 90% or more) of the input energy is lost to friction. I knew it would be this way when I was building it, but I built it anyway because I was only interested it demonstrating a concept.
@The512MB Another note about fans! I bought an ~$8 fan at The Shack and its power is pathetic. My guess would be that it is about 1/8th the power of the fan in the video. I bought a $3 fan from an online computer parts store and its power is comparable to the one in the video. Prices of modern fans are just not an indicator of power. If your interested in modding one, you may need to buy/salvage a variety and experiment to find one good for whatever exotic purpose you have in mind.
@npaltmp Talking about powerful fans... I like the Kaze 3000rpm which I get on NCIX for 8$. Be warned, this is not a fan, it's a jet engine. To get back on topic, very good demonstration. I can't really see anything better than a PC fan to demonstrate storing energy in a flywheel, using salvaged parts.
Can we assume the flywheel will be spun at the rated fan speed? I certainly have no idea why this would be valid or not. However if it's proven right, then you would know the speed of rotation, and, knowing the mass, an approximate of the energy stored in your device! :O
@The512MB a DC fan is going to spin much faster than the rated rpm with a flywheel attached instead of a fan. The rated RPM is where the fans air resistance is equal to the power output.
@makmegs I didn't mean to ignore your question; somehow I never noticed it before. Luck was a major factor in balancing. The explanation is a bit long, I will add it to the video's description.
@makmegs - mounted on a spring suspension, the device could operate fairly well, even when its out of balance. It will find its own center of gravity so to speak. Next time you have your tires balanced, watch how its done. A strobe light is used to show which side has more mass than the other. Ditto when balancing a crankshaft or the flywheel that's already in your car too.
Great demonstration! I loved it. Could you imagine putting this in space connected to a solar panel, using magnets instead of bearings? No gravity, no friction from air, constant sunlight (because there is no shade)... it could be a replacement to a chemical battery, storing energy as momentum (kinetic energy) instead of chemical energy.
Now how do I get into space? Thanks for sharing this.
Hi, You provoked me to read about micro-gravity. For simplicity, we can say that objects are weightless in space. You are right... there is still some gravity no matter where you are. I learned that as you leave the Earth's orbit, there is still gravitational pull from the sun, and going out farther away... the milky way is pulling. Hard to find absolute zero gravity.
Gravity is much less in space, less energy wasted in fighting it... device in this video should be more efficient in space.
@rock3tcat The efficiency is low, but I don't know how low. Air resistance is probably the biggest factor when It comes to efficiency. I read about commercial devices a long while back, but If I remember correctly, some do operate in a vacuum and with magnetic levitation.
Very interesting , not real useful ....I guess if you had that thing setup to for doing something then when you cut it off it could be charging some batteries to reclaim a little bit of energy ..Nice demonstration ..
will this spin longer if it's in a vaccume container?
