Nice Video man!

It just create some of the kinetic energy stored in the flywheel.

Check out my video "Pedal Powered Flywheel Generator".

Cheers!

[williiamb]

I've included a description of what is happening in the video.

[briangunn21]

did you see it? that thing just turned multiple times...that was amazing

[Mappel2006]

The problem is the adaptation for normal use.

[Gam3Junkie7]

The fact that something so simple could produce power makes me think: why the hell aren't there more alternative sources of power?

[MyExplodingHorse]

The bike chain appears to not be moving, leading me to believe it's a fake.

[itsandbits1]

@MyExplodingHorse

the flywheel keeps it going until friction or power consumption stops it

[tm874m765]

Estudar

Eu gosto disto.

Isto me da prazer, me faz bem me sentir humano e não uma maquina programada sómente para obedecer.

Study

I like that.

It gives me pleasure, it makes me feel very human and not a machine programmed only to obey.

[dissturbbed]

this is retarded..you will never peddle a generator and run a tv with it..we built several of these at school and nobody got above 120 watts..peddle all you want..you always get less energy out than what u put in..there is nothing on this earth thats 100% effencient

[Head5h07]

@dissturbbed what if the power that was being created ran a motor, bare with me, this motor ran the whole set up okay slowly increasing the speed and then with out ever touching it it would run itself and then you could gather energy from it

[dissturbbed]

@Head5h07 You cant create energy/matter nor destroy it. There is no such thing as " free energy " if someone tells you otherwise it is a scam, fraud, and etc. Its funny how a million people makes these machines out of a complicated array of magnets and state its running on its own. If this were all true we would see a million of these machines in every home. Ive been hearing about these scams since the eighties.

[Head5h07]

@dissturbbed i know energy can't be created or destroyed but theoretically you can make it run from its own energy

[dissturbbed]

@Head5h07 When something is moving or running in any kind of fashion its giving off energy and that energy like all energy is from the big bang, for example your moving and thinking beause your body is releasing energy it gets from food that food you ate got it from the sun and the sun got its energy from hydrogen which is from the big bang. Billions or trillions of years from now all this energy is going to be used up and the universe will die, there is no machine that can stop this..

[williiamb]

@dissturbbed you are correct , the machine is in fact slowing down after i was pedaling it. And it is running off of the flywheel in the video.

That was the point of the video in the first place , just to show the alternator running off of the flywheel.

[dissturbbed]

@Head5h07 If that machine is running on its own energy, what changes are taking place inside the machine. What fuel is actually being used up? My car takes in hydrocarbons and releases carbon dioxide in the process. The sun takes in hydrogen and releases helium.

[Armando2012102]

I hate the naysayers who say they can't see any practical application of a contraption such as this one. ARE THEY EFFING BLIND? The ability to make electricity ANYWHERE, ANYTIME and you can charge ANYTHING you want? That's not enough? Oh, they bitch about the charge time. WTF? Anyway, with all electronics becoming smaller every day (Netbooks!), charging your stuff will only get easier.

[CFrobertmartin]

be good for recharging batteries for anything in deep woods hunt cabin lesss weight to cary/hump in to the cabin thinking a 10-50KM hike to the cabin

[awizardalso]

williamb- Please don't get the wrong idea. I can truly appreciate the engineering you put into this. I've also set off on many projects solely because I could and the result was 'cool'. There seems to be much ado about bicycle powered generators on YouTube. Other than for educational reasons, I'm just not seeing any practical side to it.

[TheTeslaJet]

You should try living in the Rocky Mountains sometime or anywhere that cannot afford the privilage of out of your control plug in power you have. Walk a mile in his shoes before you.....people without power outnumber your opinion.

[TheTeslaJet]

My remark was for awizardalso ridicule of creative ideas like this.

[awizardalso]

TheTeslaJet- ....but you didn't answer my question. Other than a potential use I've already put forth, what other practical uses can you suggest? I'm not ridiculing anything. From an engineering standpoint, it's quite elegant. From a practical point of view, the power attainable from human effort is quite limited. What I'm asking is what can it be used for?

...and what makes you assume I haven't walked in my own shoes and I'm totally reliant on the grid?

[TheTeslaJet]

A"engineer"alsoWizard:

You miss the principle it is electricity that does not involve outside sources, in many countries charging 4 AA batteries can save a life in a disaster or emergency and people that see this can visualize alternatives. It may be fun for kids too but you may just shoot their fun down as well, attitude all about attitude. Grandma said if you ain't got nothing good to say just shut the ^%^& up. LOL!

[awizardalso]

Thank you. That's all I was trying to ask. So we're agreed on emergency power applications? I didn't miss the idea of it being self-contained and independent, I mean, that's what makes this such a novel idea and it could be modified to be 'portable' using a complete bicycle.

The primary disadvantage I found for charging batteries, is the time required. On a side note, the kids all lost interest after it ceased to be 'fun' and became more like work.

[possenti]

@awizardalso - I plan on using a similar

unit like this one day when I'm living off the grid.

It will be an excellent way to supplement my

solar and wind power. On a cloudy and windless

winter day, I'll be glad to have it. I'm finishing up my

project right now, and I'll post a video when I'm done.

[awizardalso]

At the risk of sounding like a real spoilsport, can someone name a few practical things that human generated electric power would be good for? The best I could come up with is a 14 volt, 100 watt generator could be used to put enough charge into a dead car battery to start the motor in about 10-15 minutes. Since it would take about 1 hour of moderately hard pedaling to produce about 1 cent's worth of electricity, I just can't get a grip on any real practical application for it.

[thegreatkoua]

free energy yet

[williiamb]

I found another video of my bike generator, but i cant seem to be able to post the link.

[321ozzy]

You can place the link in the information block, at the right top.

Good luck

[glenisah]

Well my ceiling fan conversion was a dud. the measurements weren't worth remembering Or mentioning. So, I have a couple of questions about your axial flux design in this video if you don't mind answering them. It appears that you are using a single magnet rotor disk?. Are your stator coils cylindrical in shape? Air core or iron core?

Any details regarding construction would be appreciated. How much power are you generating under load?

Thank you in advance

Glenn

[williiamb]

There are two separate dual rotors on the bike in the video.The one at the top with the white plastic stator is the alternator producing power.There is also set of dual rotors closer to the bike,without any coils.

The alternator has 12 round 'disk' looking coils 1.5" dia and 16-0.875Dia. by 1/2 in. neodymium Mags per rotor.The dual rotor without any coils has 24-0.875Dia. x 1" cylinder neo mags per rotor.Air core. i have some graphs somewhere of the power output i'll look for them.

[glenisah]

Thank you for your quick reply, your explanation cleared up my questions very well. I guess it was the plastic stator and the round coils that threw me off.

I have 24 -.50X.75X.25 thick neos looking for a place to be glued on to.

For now I went to plan B on my pedal powered project. I'll be using a modified GE 3/4HP ECM brushless permanent magnet motor as my alternator. It is a proven performer with 400 watt capability after rewiring the coils but I will build an axial project this winter.

[glenisah]

I have passive solar heating as my next project, plus a solar distiller in the thinking phase. I only use recycled materials where possible, so what I build is often determined by what I can scrounge. I'm happily busy experimenting just for fun.

Thank you for your time and information, it is much appreciated

[josephdupont]

@glenisah tell me more about the ceiling fan.. if you just keep it 110 volts andpower it up first.

it shouold pump electrcity back in the grid.

[jupy921]

That is a wild looking rig you have there. Pretty cool!

[glenisah]

good job

I had thought of using an axial flux PMA for pedal power too But instead I heavily modified a ceiling fan motor for my pedal power design. Testing will begin as soon as I knock out the frame. My design does not involve the use of the wheel assembly at all, Instead it is directly chain driven from the bike crank.

[williiamb]

Thank you,

The nice thing about using the flywheel that came with exercise bike ,is its ability to coast, which is what its doing in the video.If you notice the drive chain has stopped moving at that point in the video and the alternator is slowing down, running on momentum alone.

[DominickBlack]

I can't understand why the rating on this video is so low.

The design is quite nice IMHO.

[williiamb]

Thanks for all the nice comments and i'm sorry that i have not responded sooner, i had a problem accessing my account , but its fixed now.

[xxx777aaa]

ah yes, momentum/flywheels... such a rare use even on youtube.... how bout a magnetic field assisted flywheel , electronically calibrated to stabalize/harness a flywheel?

[arkansascajun]

Rube Goldberg LIVES!

[Utubeblows]

this isnt a rube goldberg device you rube

[Bullettube]

Sooner or later, the guy will tire of pedaling all day to produce the energy needed to hear his radio. Then, hallelujah! A bell will ring in his head and he'll invent a gasoline powered engine to run his generator which will free up his bike for a more useful purpose.

[ggrizzle]

i've seen a guy that could power his whole house on this setup on the science channel a couple of years ago...he only had to ride his bike for 15-30 minutes for a couple hours of energy when he used his electricity wisely...

[HelpSaveTheEarth2051]

Why this guy should pedal when he can harness the power of the wind?

[Carlstens]

Too bad there won't be any gasoline to run his generator... or power grid soon, or food for you to eat LOL

[atomicmatt3]

When the grid collapses, this guy will be one of the people that lives.

[RidgeXxeno]

lol yea, which is y the government should enforce renewable energy 2 a higher degree

[threephaseman]

Some of you who left comments are terribly rude this stuff is what Thomas Edison, Ben Franklin ect. did without thier studies on this stuff in thier carriers or even spare time ,we may not have the modern luxeries we do now. Some of you need to watch what you say! ;-)

[matthewsolis247]

Gee thanks for showing us how its done in just 14 seconds! You could have said in the video description, "Bike generator with zero fucking information making this video a complete waste of fucking time!"

[danz409]

completely agree... there's a meeter there. but god knows what settings that's on... if that is 200 watts then that is something to speak up about... bike on that for an hour and you have your daily electric... could have one of these on a camping trip or cottage on the lake... but who knows how effective this is due to shotty footage

[Bullettube]

No, once you stop pedaling, the 200 watts of work stops as well. You could recharge some batteries and thus "store" some wattage. But, he needs to figure out a way to produce a continuous supply of current.

[mclarenf45]

exactly !!

[carlosmino144]

sad but true.....

[ggrizzle]

why don't you make your own and post a vid on that...then you won't have to bitch on someones video because you didn't like what you saw...the video title was not "how to build your own bike generator" or "DIY bike generator" it is simply "Bike Generator"...

[matthewsolis247]

funny how you are the only one who disagrees with me on this! With expectations as substandard as yours the world sure would be a better place. Thats like saying, " hey! lets go to the store!" when you get there it's empty, "Hey! there is nothing here!" To which the clerk replies, "Well yes this is a store but we never said there was anything inside." Now lets see who all agrees with that one!

[itsandbits1]

@matthewsolis247

wow, do you need an anger management course. if you read the discription up above it is explained pretty well. It will stop pretty fast though if there is energy getting consumed from the generator

[tankjr85]

why don't you just use a car generator?

[ratheads]

Just chock full with information.

[drinkbudyXD]

stinky poo

[SteveNordqu]

Most generators do well 2000RPM (300ish per second) or higher; this one is at least staying hooked up at the speeds you have and generating...numbers and stuff? Get me a side angle shot so I can see how your racing flats are enduring! Indoors, the generator sounds good if it keeps the rider cool; outdoors...maybe balance the rear saddlebags and do cowcatcher /stabilizer duty? (Anti-collision electronics?)

[LeoDJ1992]

what you talking about? 2000RPM ~= 33 revolutions per second, not 300

[darthshadowxxx]

what do you use to get electric energy from that? thank you cause its really interesting

[haloZforever]

dont quit your day job thats the sam bike i have! this is classic sTrange how some folks wont comment back on things they take time to film and upload. I first saw a bicycle generator back in 1972 at Fort St. Vrain I agree with the large mass approach, its the only one that makes sense. nuclear power plant. Made sense then and more sense now. I wish I had something like to power my TV. It would cut down on my TV watching dramatically. holy craaaap ok he joined a year ago and his last login .....

[EngineerGuy2]

Excellent & an innovative approach. Incidentally, our high school physics lab had one of these for demonstration purposes. It was nothing more than an exercise bike with an automotive type alternator. Depending on how fast you pedaled, you could power a light bulb and a small B/W TV set. Yes, a more massive flywheel functions as an energy storage device (greater "ride through capacity"), though you'll have to increase the initial energy input to overcome the added ineertia.

[opodark]

that generator can light up 10 or more ctf light.. with radiant energy.. check for bedini or aromaz

[einsteinian]

I agree with the large mass approach, its the only one that makes sense.

[Williamburkee]

What i have in the video is an excersize bike ,one with a flywheel , attached to a bicycle , driving an alternator which is rectified then powering the meter which is reading amps.

The object of the video was to show that the flywheel could power the alternator for a period of time .So that is what its doing , slowing down , and being powered by flywheel alone.

sorry for not getting back sooner, everytime i tried to get a new password from youtube i never recieved the email.

[Bullettube]

That's good to know.  For how long does the flywheel spin? Many, many years ago I bought a bike generator from Western Auto that ran off the back tire of my bike. It was strong enough to power my head and tail light as long as I was moving. "D"cell batteries powered smaller bulbs when I wasn't moving. The friction wheel that made contact with the tire was engaged by a lever and cable on the handle bar.

any still shots with diagrams/

[SpiritsoftheWolf]

ok your description says BIKE GENERATOR.... what in the hell am i looking at here?? are you making a battery charger here or in case of power failure, start pedaling to get some lights in the house to burn them calories? where is the teacher when you need one?!?!?

[motoshop4]

a eso se le llama dinamo y lo vende cualquier bicicletero

[Muleagain]

Let me see, you have a brake rotor, and an electric motor driving what? I liked the music, do you think you can add an explanation of exactly what we are seeing? Just a hint you know, nothing dramatic like telling us what it is you think you have.

[sergioalcala]

I don't get it....Who was supposed to explain this I asked my mom she didn't know......Who do i ask?....Yea maybe Williamb....=]

[woww1994]

true

[jmoyet]

well that sucked.
