Pedal Generator w/ 250 watt bulb.

[discoide1451]

generator 24 v site weeb discoide1451

[mountain177]

the bulb is AC not DC. and wasn't that a DC motor. it would not work. but good vid.

[SSparks555]

@mountain177 The 110 volt, incadecent bulb, will work on AC or DC just the same. It was a DC motor yes, but when it was in the electric lawn mower, it was hooked up to a rectifier that converted the AC to DC. Great question.

[SSparks555]

@sOUthpArkMExXNiKKUZz A (7 Watt) nightlight would be a breeze compared to this 250 watt heat light, lol.

[antris123]

totaly awesome!! man how u done this.. your lamp.. its MAGIC!! it´s AWESOME

[Johnnylofat]

My wife says "my bone has a little machine."

[sonichedgie]

wow , human output is 250W ? thats better than i thought .

[bloodynikka1]

@sonichedgie the average human output is better than that! we have a peak out put of 1 kilowatt or equilivent to 1 hp.

[sonichedgie]

@bloodynikka1 : wow , it will do microwave !

[schlusselmensch]

@bloodynikka1 Maybe if you're Lance bloody Armstrong!

[coalandnuclear]

@bloodynikka1 a hp is 746 watts, thats not a kw

[MinhazulH]

Now the thiing is,someone needs to invent a human generator that supplies constant energy. But congradulations on producing 250 watts.

[webovisionca]

You should invent a machine that allows my dog to generate power when hes in the back yard running around

[SSparks555]

OMG, how much energy do you think he would generate? lol.

[webovisionca]

@SSparks555 I have been thinking about it for a while. My friend has a slightly crazy dog that runs around in large circles non'stop, If you put a generator in the middle i'm sure he'd pull it.

[SSparks555]

Just make you a bigger hamster wheel with a generator and a carrot, I mean, BIG ham bone, lol.

[webovisionca]

put a few cat on the other side for a turbo boost

[cheezycam]

I think machine like this are a great way for people to apreciate the energy that they use. 100 or 200 watts doesn't sound like much untill you try to produce that kind of power your self. Rigs like this would be a good idea for every school. If a kid is misbehaving, he can generate electricity, burn off his disruptive energy, get exersize and learn.

[proaudiohd]

Most people can generate about 100 watts at full power. You can light a bulb with less power than its rated for, it just wont be as bright.

[TheGeek1028]

Which is basically what a dimmer does. Reduces the amperage going to the bulb while still keeping the filament glowing.

[SSparks555]

@TheGeek1028 Actually, a dimmer just reduces the volts which, in turn, reduces the Amps and the Watts used, proportionally.

[SSparks555]

@TheGeek1028 Good question though.

[Jay00Cole]

How hard was it too pedal to get up to 250 watts? What would you compare it too? How long could one pedal at that load?

[SSparks555]

@Jay00Cole Its is comparable to a steep hill. The lights bulb was much easier.

[vik95170]

did it realy prudice 250 watts ? can you do more or it is so difficult ?

[SSparks555]

@vik95170 It did produce 250 watts. The bulb heated up just the same as if it were plugged into the wall. I could do more yes, but it would be one heck of a workout.

[vik95170]

250 watts that's always not bad ! congratulations

[CacaouetteLeVrai]

My project is to power my whole house using pedal generator and storing unused energies in batteries.

Using several coupled gears instead of a direct bike-belt-motor , you would significantly increase your RPM, therefore giving more power.

If my explanations aren't clear, feel free to ask any question.

[xtruder02]

im actually trying to do the same LOL. yea i have a question for you: do you need to conect the wheel of your bike to another wheel smaller to get more linerar velocity for the generator right???

[CacaouetteLeVrai]

Yes, that's right. Here's an explanation :

Gear #1 - Pedal gear

Gear #2 - Smaller gear chained to Gear #1

Gear #3 - Gear as big as gear #1, but WELDED to gear #2, so the RPM of this gear is the SAME as the gear #2.

You may repeat this scheme several times, but you need a panel to fix all these gear on. If you want a drawing of this, let me know.

[xtruder02]

thanks a lot for your advice... but im afraid 3 or 5 wheels are enough... hahaha. IF I CAN generate 220 v. i will try to charge a battery during the day with the wheels and then in the night it should be more confortable to turn it on. xDD

well honestly if is not any problem for you, it would be nice a drawing please.

[CacaouetteLeVrai]

Well, send me a private message with your e-mail address, so I can send it to you. I'll probably make a video about my explanation if I have some spare time, but it'll be quickier to send you the drawing.

[scott1506]

hasnts someone invented a super efficient gear box with a really high ratio. e.g 1 full rotaion of pedals=100 rotation at the rotor??

[crapkillerz]

yes... of course... its really simple... except not very useful because you would have more RPM... but less torque.  (it would spin faster, but be harder to turn)

[atheisttotindekist]

Sure... but HOW would this increase the energy output? Fact; It does not, it just makes it a lot harder to peddle.

[scott1506]

@atheisttotindekist more turns at the generator side makes it turn faster = more power

[SSparks555]

@atheisttotindekist Actually, a 100 watt bulb @ 110 volts is easier to do than 60 watts @12 volts. I have had it (the generator) in both 12 volt and 110 volt configurations. When you use Ohm's law, it's not the watts that determines how hard it is to pedal, but the amps.

[proaudiohd]

You have that backwards. Amps only measures current but it doesnt tell you how much work is being done. Power is measured in watts. Also just because you're pedaling against a 100watt bulb does not mean you're putting out 100watts. You can deliver 20 watts and the bulb still lights up (think of a dimmer switch). You need a watt meter to determine the power being delivered.

[vermiman]

100 watts at 110 volts require less than one amp, while 60 watts at 12 volts require 5 amps.

[pixar5]

got a question i got a 110 volt dc motor out of a lawnmower like you did can turn it ,its so stiff tryed wd 40 still cant spin it very difficult how did you get it to spin so easily ?

[SSparks555]

Mine wasnt really locked up as it sounds that yours might be. Its hard to say the best fix. I tried removing one of the ends, on another motor, and was only able to remove the back side. If you can do this, which would expose the rear bearing better, you might be able to get some wd40 in that way. I could not get the core from the front bearing and housing. Be carefull getting any oil on the brushes or rotor contacts, They dont do well with oil on them.

[nua4s]

very cool. In the meantime, we can buy carbon offsets at carbonfund website. Its pretty cool, you can offset your car and air travel. You can also choose the 100% offset option or donate clean power.

[SSparks555]

If I just keep pedaling I can off-set alot of things. We can all do our own part to off-set things for the better. To go 'Green' is within all of Us if we would just make some adjustments.

[skseagull]

I watched most of your vids, surrounding power production, now for your mentors.

Thanks for sharing your ingenuity. Sarah/Sahara

[SSparks555]

My mentors helped me become the person that I am, I think.

[MueraTelevisa]

250 w is a lot of power! but were can we find more information about how to build one of this generator?

I like it for make some exersice and generate some power for my computer...

[88simran]

imagine how much energy could be gathered if this system was set up in all of the work out gyms across the country!!! all those excess calories could be put to a good use.

[SSparks555]

I agree.

[ozjthomas]

Cool. I think a combination of "smart" technologies(mostly using nature to our advantage to save on heating, cooling, etc), reusing old materials and using unique technologies like this is the way of the future. Thanks again.

[SSparks555]

A 110 volt dc electric motor out of an old electric lawn mower.

[pixar5]

im getting a general electric electric lawn mower from a friend should do the trick do i need to hook up a capacitor to get the 250 watt light bulb to light up ?and if i get one what type should i get

[SSparks555]

A capacitor will only work good if you generate the lower voltages like 12 volts. Then a 1.2 Farrad capacitor will work well at smoothing out the voltages. This pedal generator I built runs at a really hi ratio, which turns the dc generator fast, thereby giving me 110 volts DC. I have ran this at both ratios and voltages. It is easier to pedal generate a 60 Watt light bulb at 110 volts than it is to pedal a 60 Watt (RV light bulb runs off of 12 volts) at 12 volts.

[AnonymousX2]

Pedal power seems like a good idea.

It seems you'll get better efficiency...as generator and gearbox technology improves.

Someone should have a contest to see who's pedal devive can put out the most power.

[MaxSachs]

Hook up a lead acid battery and inverter to store energy, it must get annoying to have to pedal everytime you want light...
