Nice job explaining how the alternator works and a nice demonstration. Someone else posted - you can use a "Self Exciting" alternator from GM, also called a "1 wire" alternator. At 1500 rpms, the regulator is self-exciting, providing power to the field coils. Using the alternator to charge a 12V deep-cycle battery can provide a nice "reservoir" of energy. As you know, 200W continuous output is a lot for most cyclists. 100 Watts is fairly manageable for people who are in decent shape.

[@tankertemplar752]

I loved this episode of Gilligan's island. Nice to know the professor was right after all!

[@dustdevil317]

There's a dozen ways around the complexity you have in your circuit. First off, GM made this thing called 'a one-wire alternator' that auto-hots the stator when the alternator starts rotating. You can also wire this yourself with a non-one-wire alternator. Alternatively, put a 12v wet-cell or rechargeable in the circuit that has the inverter in it, and simply hot the charge circuit as you need. Finally, if you take that rotor out, remove the brushes and did some machine work to change that armature over to a permanent magnet configuration, then you would have an always-hot stator, without need to 'hot' the stator (the main reason that alternators have powered stators is to conserve price and weight, but for an AC generator, you can drill and insert N52 neodymium magnets to make the stator 'always magnetized').

[@davidblomdahl5518]

Wow, thank you for the explanation of the difference between alternator and generator. I've asked at least a dozen people over the years that have electrical related careers/self appointed experts and not 1 person could tell me. You are a valued asset and should be spared if zombies ever take over.

[@martiwoodchip4518]

That's very clever there Einstien but I think that I have you beat!, I set up a water wheel down by the river and plumbed a 4" water line from about 150 feet up stream past where there is a 5 foot drop. With the water coming out of the end of my pipe with considerable force it flows onto a home built water wheel that spins a shaft connected to a gear box and increases the speed 150 to one. with this set up we mounted a real 110 volt generator head and wired it to an extension cord routed up to my house. We comfortably can use about 600-900 watts of 110 volt free electricity which is more than enough to run all of my LED lighting and electric fan blowing air over my wood stove. The only thing that I now need to set up is a remote water cut off valve so it can be safely shut down when leaving home. The weight and force of water is very powerful and if you set it up right you can get free electric power with minimal water flow but you do have to have at least a good 5+ feet of drop and 4" pipe diameter or larger. A simple diversion screen angled sideways keeps the inlet of my pipe clear of river debris. Picts and video coming soon!. Marti

Hi enjoyed watching your videos. It gave me the knowledge to build a backup up off grid 12v charging device similar to your design. I used a second hand 100 amp alternator, cycle turbo trainer, old jump lead switches etc. Basically I can pedal in high gear with little stress on Crank & alternator rotation. Pushing rear wheel by hand has alternator pulley & rear wheel rotating freely. Obviously when exciting you can feel load slightly but you can cycle immediately in high gear. Tyre, inner tube & turbo trainer tiny freewheel resistance roller removed. Belt goes round backwheel & alternator. Turbo trainer folds in half with alternator attached. Bicycle comes off turbo trainer & can be used as normal by just adding tyre & Innertube. Bike kept in campervan with turbo trainer & can be used to jump-start van or charge leisure batteries. Beats charging with a slow battery trickle charger. Basically fully off grid backup. So glad I watched your videos explaining everything in detail. Something I have always thought about making. Now I have & it works well. Lol.

[@tazmun]

For any real world applications there should have been a 12 Volt Lead Acid battery connected to the circuit as is intended by the alternator design. DC current isn't totally smooth coming off an alternator as it still has some pulsation in it. Batteries not only act as a storage device but also as a filter smoothing out pulsations and voltage spikes. Continued usage would probably result in failure of the inverter, solid state devices connected to inverter, or static noise in any audio device.

[@MrRedFox13Photography]

lolz

[@MrNamegame]

What you could also do is use the derailer to vary the amount of power output you are giving...if whatever you are using is starting to cough out on your electricity, you just keep shifting up and pedaling at the same pace. This will allow you to be able to be more energy efficient with your body too, as since you may not be using as much electricity at some points rather than others, you can gear it down and therefore tire yourself out less as you are still pedaling at the same speed, but with less pedal force applied. Also, if you want to use this setup for a very, very long time, you may want to replace the plastic pedals with metal ones. I find that on a normal bicycle, even if you do not stand up and pedal using the bike, you can still wear out those cheap plastic pedals so easily. With a set of pedals that AT LEAST has a metal frame of it's own aside from the steel pegs inside, you can expect the pedals to at least be able to withstand you pushing the bike hard everywhere you go for about 3 years if the steel frame is the worst available on the market.

[@hakunamatataadventurebus5944]

I'm pretty sure that Delco makes self-exciting alternators that are used in some trucks and boats. They're known as single-wire alternators and use residual magnetism in the rotor to excite the voltage regulator.

[@slenderkid1018]

You can ask Auto Zone for a single wire GM alternator and they will know what you are asking for. Tell them to test it for you. That will put residual charge in it. Now, you can hook it up to a battery and you only need the single battery wire for it to work. Of course you still need a ground wire to the negative of the battery. Now when you start pedaling it will spin up and the residual will be enough for it to take off charging. No switch is needed. I did that on my diesel boat. Auto restorers do that on 6 volt conversions or generator conversions to alternators... You are welcome.. 40 years in electronics.

Great idea! Problem is self- exciting alternators have to constantly be used or else they loose their charge which wouldn’t work well for a set up like this which most people only use when the power is out or when they go camping. Unless there’s an easy way to re excite the alternator?

[@Milosz_Ostrow]

[@garlihu]

A human powered system can generate the value of some 0.243 USD in an hour (if you're strong and you have a very efficient system). That means a hudred thousand guys in 20 minutes can make $8000. If one single device costs a a few hundred each, you can make a profit in less than a billion years ; )

[@brucejohnwayne7783]

garlihu Thanks for the answer. 0.24 is quite a bit.

[@garlihu]

The main problem is that it's very expensive compared to the power you can produce. A human being can generate 100 Watts of power and about 60% of it is heat. My maximum output is approx. 400 W but no longer than a half minute and I'm an avid cyclist. So basically you need to spend hundreds of dollars on a device which will produce so little electricity that you can easily charge your cellphone with it but you can't really charge your laptop battery. (My power supply consumes 70 W).

[@MidnightMarrow]

I was on a stationary bike, newer digital one. Gives all your stats RPMS etc but this one gave Watts generated as well. The bike had speed settings up to 21 which gave quite a bit of resistance. I was cranking it over 70 RPMs and was generating over 2000 watts according to it. Because of that I was trying to figure out a way to possibly generate that with a pedal based system and perhaps a load of Ultra Capacitors for quick charging and storage.

[@garlihu]

+MidnightMarrow 2 kW? It sounds like you're a superhuman. Tour de France cyclists' full power output is 100 W on the long run. My temporary maximum was around 400 (maybe 500) W (for 20 or maybe 30 sec). 2000 W for one hour equals 1720 kcal. My daily(!) energy need is 2100 kcal. That's for 24 hrs including quite a lot of physical activities. I doubt that anyone can produce 2000 W for more than a couple of seconds. I mean there must be a measurement issue with that bike. 2000 W is 2.68 horsepower. That's a lot!

[@DVICK83]

Dang, that's a lot of work to chop some onions...

[@barryfoster8535]

+D “SUBSONIC” Vick LOL! You are so right. I could have chopped an onion by hand using 20 times less power. What is the point here? It certainly isn't about making life easier or saving energy.

[@magicalsimmy]

+Barry Foster The point wasn't the onion. The point was that we can generate power in more ways than burning coal and other unsustainable methods. He's showing what's possible on a small scale. Is it entirely practical? Probably not, but it's fucking cool as hell. ;) I'd use it to charge my mobile devices. If I don't exercise, I don't get to play Clash of Clans on my iPad. There's motivation to exercise right there, and fuck knows, in our indoor, couch-potato culture with a growing diabetes epidemic, we need SOMETHING to motivate us to get off our asses. :)

[@sparticus214]

At least the bike has a transmission to increase wheel RPM 3times peddle rpm but you really don't need that many speeds because max gear is the same as a 6speed but its easier to buy solor" equipment because it only cost a few hundred to build a system to power 1 appliance.

Alexander Smirnov Every time someone mentions generating electricity, some idiot comes along and mentions regenerative braking.

This is great - think I'll try something like this myself. How hard is it to pedal once there is a load on the alternator? Do you think it would work modifying the rear wheel to a flywheel so you don't have to pedal continuously?

[@Y10Q]

it's so hard that most people don't want to do it for more than 10 seconds. It's like sprinting at your maximum speed and for most people that is a 10 -15 second maximum event. Alternator takes like 3-5hp from a car when it's charging the battery.

this is a great question. i have seen this done. a friend of mine back in highschool built a rig that powered his home computer. this was back in the days of pentium1 processors and HUGE power supplies... so in his rig, it was not possible for a human to power a computer during normal use... however, he could charge a pair of battery backup systems that would allow him to use his computer for about 30 minutes for every hour of cycling. i have seen a few other projects online, too.

Hook up a 12 volt battery to your system. Much more practical.

[@williamkunte5361]

And what will keep that battery charged you Tweeb? 🙄

[@jerryfleming4013]

An alternator creates AC voltage and the internal (DIODE) rectifier converts the AC voltage to DC. The internal voltage regulator regulates the DC voltage to around 14.5 volts DC. The external inverter takes the DC voltage from the alternator and then converts it back to AC voltage to run the food processor. I wander if we could just regulate the alternator AC voltage to 110 volts and what the wattage output would be? Hmmm Also you can use a self exciting regulator and do away with the battery source.

I have not been able to get it to produce a charge. The way it is hooked up now is I jumped the "s" wire to the positive output, run direct to a 12v battery and a direct ground to the neg. terminal. I beleive what I am missing is the switch. The alternator will not generate power with out the switch I guess?

[@mykeyt6939]

And I respect the way you are leaving it for them to figure out themselves as well

[@snowdog90210]

Why are all you people commenting that this is a useless experiment? If you have a fat wife, you can make her bike to power the stove or oven.

[@bamaslamma1003]

What if your stove is gas?

[@NikoxD93]

not very efficient to convert your energy into electricity and then in onion cutting motion but electricity is more universal than onion cutting motion :p

[@TheVariableConstant]

Very efficient way to lose weight and burn extra calories :)

[@mihc15]

TheVariableConstant Can u imagine a hall of bicycles connected to a generators =D. U cycle and u get paid xD.

[@hillaryhart2093]

mihc15 yeah all the health clubs could be powering the cities, and how about if you get a payback for how much energy you produce during your work out?

[@fuckyougoogleplus8667]

Hillary Hart Even if every single health club had these bikes hooked up to generators and every bike was being peddled by Lance Armstrong with a veinful of steroids in him, it would not even power the health clubs themselves. You have to peddle for like 15 minutes just to make toast.

[@hillaryhart2093]

Funny! At least people are trying things and experimenting, if average people are doing these cool things then imagine what the really amazing scientists are doing. It's fun and healthy and positive so who cares if it isn't the "answer".

[@UltraInvestigations]

Nice setup. Very practical because the most expensive part, the bike, does not have to be bought just to have this rig.

[@crobulari2328]

I bet he`s knackered after that.

[@passedhighschoolphysics6010]

All of that to save $0.12 in electricity. Guy might be good in science but failed in business math.

[@almostpositive]

Give it a couple decades or so...

[@wheelsupat7]

At what point did he say that this is more efficient and economical than plugging the food processor into the wall?.......oh that's right....he didn't.

[@passedhighschoolphysics6010]

Are you willing to pedal your bike for 12 cents an hour to power 1 50 watt light bulb for me?

[@mibars]

I'm pretty sure he isn't doing it to save on bills, but for fun, to excercise and demonstrate the possibilities. And if you live in rural area it might be even useful when power goes out to generate a little electricity to for example recharge batteries used for UPS/inverter without the need of running noisy gas generator

[@passedhighschoolphysics6010]

mibars - Any ideas how much work or pedaling one would have to do charge a UPS battery or to keep a 60 watt light bulb lit? To charge batteries for a UPS or inverter it would take someone three weeks pedaling several hours a day. Not very practical. To keep a 60 watt light bulb lit one would have to pedal continually at a semi-strenuous pace like 20-30 mph on a level street. Just go to a gym and see how many people can do it? Even fit people can't do it for more than 20-30 minutes.

[@nagaming1941]

why not using a motorbike. free electricity with gasoline

[@jesseanderson1484]

gas aint free....

[@NewPhilosopher]

May as well get a diesel generator instead if you were going to do that.

[@davedumas0]

free electricity with gasoline OMG i hope you are trolling lol

[@acebestwords]

The purpose is to get free energy right? if you do it like you said, then you using fuel to create electricity.

[@TheGolfinj98]

I just did the same setup with a self exciting alternator (Delco 10SI). With the field excited, but the alternator not connected to anything, it is quite easy to pedal. With the field excited and the alternator connected to a battery, the pedaling is very difficult and choppy. I don't know if using a dc motor as a generator would smooth that out a bit, but I could not pedal for very long using my setup. My inverter would not work being hooked up directly to the alternator. Also not sure as to whether if the pedaling would be smoother using a setup like the one in this video using an alternator that requires an external source to excite the field inside. Any suggestions?

[@thomasdinan7043]

You just need to put some type of inverter to that battery so that it's draining that battery constantly, and plug in something into that inverter that use a lot of power

[@JoaoAmadoTV]

What Bike Wheel Stand do you guys advise? Any Amazon suggestion?

[@JaminiPadhi]

Ingenuity, creativity of man is limited by thought and imagination. Nice video..

[@thug4Lifelrapcrapl]

Great job man, but them crocs eeeuuuuuhhhhh "shivers"

[@muhammadrameez3093]

Very nice, very helpful knowledge.

[@ab_ab_c]

Well done & well explained! What is the maximum amount of electrical power that you can get out of the system? Thanks for sharing!

[@vagrantrandomstuff2312]

thanks for the information sir. it is really helpful.

[@reforgedcriterion1471]

And the episode of Black Mirror pops into my head.. Fifteen Million Merritts. lmao.

[@sonofivar8040]

Hello, Great video, thanks for posting. I am thinking of doing the same thing with maybe a stationary spin bike using a 50# flywheel to generate power to charge batteries in my off grid system. I would like to use a car alternator because they are cheap and readily available. Do you think adding weights to the rear wheel (flywheel) of your bicycle would be beneficial ?

[@LaJewel]

Sure, but lots of people want to know how to use these alternators as alternate forms of energy, such as in wind turbines. I personally have been looking for bike applications (as an additional backup for an off-grid cabin) , and this looks great to me.

[@SOLIDSTEELEDOTCOM]

Great vid, Have you considered mounting a small dc motor to the shaft or additional pully mounted to the altinator to take advantage of the 40:1 , in order to provide the constant HIGHER base charge for the altinator eliminating the batteries and increasing potential

[@wizardofx]

I remember seeing this setup in the movie Soylent Green. One day, we may all be using this to power our lives, if we don't straighten out our geopolitical business.

[@CCMPULM]

I am interested in the materials list for the frame to hold the bike, as well as the belt for the tire alternator. Many thanks for a very good instructional video.

[@kellerfamilyband]

Where did you get the black part of your stand that holds up that back wheel? thanks
