HAHA!!.You never mentioned how many amps it puts out at 120 volts AC,it lights up a 100 watt light bulb,so what??. It takes just under 1 amp to light the 100 watt light bulb at 120 volts. Volts × amps=watts
Back in the 1960's (Yes, I'm old as dirt) They had a kit which, by throwing a switch mounted under the hood (bonnet) of one's truck (lorry) or car, you could bypass the alternator wiring and obtain higher voltage to run power tools. It was a similar setup.
The battery is powering what is called the "exciter coil". When used in your car, when you turn the ignition key to the START position, the key switch connects the battery to this coil. Once the car motor is running and you return the key to the RUN position, the exciter coil is then powered by a voltage sensor in the rectifier/regulator that was removed in the video. Since a car's engine will vary in RPM as you are driving, a constant output voltage of 13.8 volts is maintained by the voltage sensor regulator by adjusting the voltage to the exciter coil. As the engine turns faster the voltage is reduce, and vice versa. As a reliable, stationary home generator, a speed control or governor on the drive motor would be necessary so the output would maintain a fixed hertz rate. For powering light bulbs hertz rate is not so critical but for AC motors and electronics it is. This is a three phase alternator. If you want to use the other outputs in combination, you definitely need to learn why three phase is different from normal home A.C.
A kit was sold in the 70's that you wired into your alternator while mounted in your car. It consisted of a multi pole switch and and 3 110 volt outlets. One for each phase. The battery in the car would not charge while in 110 mode, but provided the field voltage.
years ago after a hurricane i built a gen with a 5 hp honda,a few pullies n belts 2:1 reduction and a alt from a 1986 nissan d21 pickup.motor at idle put out 78-80 volts from the nissan alt,half throttle gave me 105 volts.i had a dc to ac converter lying around that helped.86 nissan alt has no built in voltage regulator.not saying its a better alternative to your method.....just mentioning,cuz your vid reminded me of what i had done 20 years ago.it may take less mods to get the job done. i ran that setup for 6 days,15 hours a day with no issues and only using 1.5 gal gas per day.i was able to run a full size house fridge,tv,microwave and the alt was warm to the touch.later i added a 12v mower battery,and a trickle charger that feed off the alt to charge the battery,and added a car electric radiator fan to keep the alt and converter cool.just add gas,once fired up it was a self contained unit.i did however had to excite the alt on startup before it would make voltage on its own.
It's very simple, just bypass the diodes and control the rpm to make 120 volts off 2 of the leads or youse all 3 leads and get 220 out of it but be careful it is a dangerous thing to play with just be careful it is unregulated AC current
Good job, I like your passion on that field . Plactise will make you better. Alternators are induced magnetic generators and once induced with 12 v high amp they require unbelievable torque to spin them.
An alternator generates a.c.(alternating current) that is why it is called an alternator instead of a regular generator which produces d.c.(direct current). A rectifier acts on that a.c. like a check valve works on pressurized fluids or gases and only let's the current flow one direction Instead of alternating a certain frequency (hertz). I'm a fabricator/heavy equipment repairman by trade but when I was 22 I worked for a few months as an electric motor/alternator/generator /air compressor/small gearbox mechanic
Older 80-90's Chrysler and Jeeps have alternators that are externally rectified. You can also make an arc welder with the same alternator running slightly over idle.
Well done , we can as well use a Magnetic instead of the Armature magnetic copper wire, so we don't need a Battery anymore, so, we'll have a big DC motor which generated an AC voltage, but of course we will need the Transformer continually.
The two 12v leads act as a controller for the alternator. The higher the voltage on those wires, the more the alternator puts out. That is how the alternator controls its output when the car changes speed. With no voltage on the 12v lines, no voltage will be produced on the output. This is because there are no magnets in a car alternator. Just an electromagnet controlled by the 12v input lines.
Most all alternators generate AC in the primary coils DC on the rotor there's all kinds of configurations to play with I use these in a AC configuration for welding works great😁
Greetings Mr. Electron, I just wanted to say I love your videos. You are very informative and definitely a very smart guy and also seems to me that you're a nice guy. Please keep up you're great work I am learning alot from you. Sorry no questions just wanted to say hi and I appreciate you showing us things we wouldn't know without you. Big fan of your work ;)
No offense or anything but these have been around for decades. It's easy to do and you can even by the hookups right at Walmart. I have one that plugs into my lighter and can power a 160 watt bulb. You can get them pretty big too. Some new trucks now come with this in them from the factory. The unit that will do this usually comes with plans or drawing of how you can hook the device up, power the alternator with a small gas engine like from a mower or something and make useful AC current. It won't be much, but it'll power like a drill or something in a pinch, maybe a bit more. No matter who you look at it, the alternator needs to be spun too. Otherwise there's no way to generate any juice at all. And you need a power source to excite the fields in the alternator - like a car battery.
To run this contraption on a permanent basis, you will need a separate engine or an electric motor to power the alternator. The AC voltage will be provided by the transformer capacity, the watts will be according to the amperage generated by the alternator. This is just for experimental trials, not to light up an area as needed. Dec. 11/18.
good idea but if you put a motor to turn the alternator it should run for ever and it could charge the battery and the same time give 120v through the adapter
That will not work! Perpetual motion machines are not possible above absolute zero, thermodynamics are tough to overcome anyone that attempts this is a fraud by definition... In the real world we have heat and energy loss, nothing can create energy without creating heat, 2nd law of thermodynamics.
Any electro mechanical generator is going to put out alternating current because the brushes cross poles of negative and positive creating a sine wave above and below 0. The alternator then must have a rectifier to filter out the neg or pos side of the sine wave thus direct current to charge the battery of the car.
You are not actually getting 120 volts from the alternator, you are only getting the 8.6 volts ac from the alternator. you are getting the 120 from the step up transformer. Also, the 120 volts is unusable by any electronic loads that require a steady 60Hz.
An important point: An "alternator," by definition and name, produces alternating current. It has a rectifier (diodes) to convert that alternating current into direct current.
thank you for this video. I want to wire my alternator (PMG) to a power strip to power a motor and I was not sure what wires to use. It looks like I can pick any combination of two wires from the 3 wires.
Finally someone is showing what we've been doing for years. I could show ya'll how you can do the same thing to power your homes using this method. He's bullshitting ya'll with this one light. He not showing ya'll how to power everything in your homes.
Yes agree the alternator does produce a 3 phase AC voltage, but where it gets a little complicated the frequency is unstable! The frequency won't have much effect on a light bulb, but I wouldn't try plugging a computer or TV to this! Normal house voltage of 120 vac operates at 50-60Hz Yes its designed to have high current output, the windings are wound with heavy wire but with less winding its a trade off with a lower voltage. I believe though with todays technology this can be over come to obtain a useable power source, something I'm going to experiment with!
What kind of transformer did you use? The ratings on it, so I can try to find one, would like to try to make a back up generator when my power goes out
Great job. Very good explaination and demonstration! Have you tried to connect two additional transformers to the other 2 output phases...to produce 3 seperate 110v outputs? Have you tried to run wire from all 3 phased output terminals to the voltage regulator (which is laying flat on your desk) and connect the voltage regulator back to your battery to charge the battery...but the. tap ONE of the 3 phases with wires to your lightbulb? Doing this, you should be able to both charge your battery AND have an AC light bulb.
Awesome, also where did you get the 12v to 120v transformer? Did you salvage that from a home appliance like a washing machine or an exercise tread-mill?
I wish we had a scrap market where I live, but sadly we do not. I’ll find one somewhere, thank you and keep making cool things and showing us how you do it!
Guys, you can use this same set-up with a AC Motor on the Side, plug the AC motor into power from house or Power source, with belt from ac motor to ac Generator--get ac generator up to speed and then Unplug Motor and the Alternator will Run Ac Motor Plus Supply Power to House or Working Tools--Many people across this land are using this Set Up for Off Grid Power--Perpetual Motion Machine-- DC Motor Run off Battery for Running Up to Speed will Also work but Rectifier will have to be used to Unplug from Battery... There is a man from Memphis who is Selling the Plans for this Kit for $49--he is Running All his 110 Recepts. in House off this setup--according to him, saving Big Bucks....
If hooked to wind or water power, you would only need the initial kick from a battery. Then your 12 volts could come from a step down... Just like the old generator days. Give it a kick, it runs, no battery.
your clip at the base of the alternator is shorted to the vise, hopefully you don't have a neutral connection connected to the chassis of the alternator otherwise it won't be good when energized!
Alternator in this video had a rectifier removed, correct ? Once you remove rectifier from 12V alternator you get AC current right out of the unit. Why would you need to use transformer to make it AC ???
output voltage on a car alternator is 8 to 12 volts ac with about 60 to 120amps .what the step down transformer does it lower the amp and raise the voltage in ac because take note of car battery it has 440 cranking amps and the electricty amps max bout 25amp breaker nomal home ampere
Transformers only increase or decreases ac voltages depending on transformer windings. They don't make ac voltages, they only change the voltage that's fed into it... and they cannot pass DC current.
In this method, the voltage is high but the current is low.Also, only one of the three stars can be used.Please show us a way to increase the power of all three stars and use it And of course intermittently
This is an ancient shop hack. After you remove the rectifiers and seperate the winding you'll have created a 3 phase motor. Use a Y 208 3ph. to power it. Big ones (90A) output 5 horse power. Won't run on single phase house current
Very cool idea. How can you keep the battery charged? Would a capacitor be better suited in a loop from the alternator since a battery will eventually fail? I have a water fall I'd like to try this on.
Drone Meets Nature: I don't recommend you use this *as shown* as an alternative household power. The output is three phase and your home is MOST LIKELY single phase. To constantly only use one phase puts lateral torque on the rotor and will ware out the bearings very quickly. As a water powered generator you would need to come up with a way to govern the RPM to a fixed value to keep it at 60 or 50 hertz. This would be 30 or 60 RPM depending on how many wingdings are used for output. An automobile alternator is intended to spin at 750 to 3000 RPM to generate maximum amperage. The best solution is to leave the automobile alternator as is and put it's 12 volt output through a 120 volt inverter. If you leave the rectifier on the generator, it is internally wired to supply the exciter coil with current and holds the output to a fixed voltage regardless of RPM. The battery is only used initially when the generator first starts to turn to energize the exciter coil. It is continually necessary here because the regulator circuit was removed. A capacitor could be used to "start" the generator. A car alternator can "start" with as little as 2 volts in the exciter coil. P.S. there are a rare few alternators that have a permanent magnet coil that supplies current to the exciter coil to initialize the exciter field. These don't need a battery connection at all and are commonly found on gas powered portable generators started with pull cords and some diesel powered generators.
If you can get 240 volts ac an you tell me maximum current please ? Im trying to do this to run my fridge in a blackout using an electric motor to spin the alternator !any reply appreciated? Thanks
That is the direct connection uses for a testing,buti a common usaged of that features is need diodes,,in a possitive and a negative,polarity from the direct current to the alternating current,must use the degnified rectifier diodes who devides the current into lights and others continously....buti in a way its amazing tuiturials....
Oh!! Okk thanks brother But can please tell me how can I save my brushes???? By changing the brush every time or by putting a new brush which is better then it?????
I had a kit that I bought in a closeout bin at western auto? Circa 1986. Anyway it was for a Ford specific with all of the goodies on the firewall. And I had a 67 Pontiac. This has been around a while!
Can a car's alternator to charge 2 batteries at the same time? I was use this method to charge my household power back up battery when I'm driving. Driving and using petrol is just a waste so why not use disposable energy to generate another energy? hope I'm making sense.
Good job sir I like your ideas n your project is really good,can you help me set up a toyota 4 pin,altonator, like a wind mill so once it spins it charge car battery so I could put on a inverter like let's say 300 watts ? Help pls thanks
Why does it want to draw down and kill the electric motor when I put the positive terminal on the rotor of the alternator it doesn't want to pull it. Can you please help?
IT'S NOT A NEW IDEA! The reason there is a voltage regulator IN an Alternator is because an ALTERNATOR puts out 120 volts per coil on the Stator. The Term ALTERNATOR comes from the fact that it puts out Alternating Current, which is converted to 12 Volts DC through a Diode Trio. Ford at one time had Alternators that had 120 volt AC terminal for AC accessories, even today Tractor Trailer trucks have an AC output on the alternator to run accessories inside the cab.. So getting AC Voltage out of an Alternator IS NOT a New Idea by any means. ANY AC Voltage you get off of an Alternator will need a Rectifier/Voltage regulator to keep the Voltage from fluttering and spiking. Lastly, no matter what you do, you still need 12 Volts DC at about 10 amps to power the FIELD on the rotor to get an alternator to produce any kind of voltage.
If you attached it to a water wheel near a river you would have free electricity if it was geared right how many amps do you get out of it and how long do you think the alternator would last at full capacity running 24/7 just curious would it burn up quickly
Yes it will generate good amount of energy. Its designed for continuous operation to it won't burn up.. although the brushes will get used up quick coz of continuous operation. Its a 64Amps alternator
I really doubt the alternator is the limiting factor in this project. That tiny transformer going to be lucky to push 3 amps before it melts. For the cost of a large enough transformer to handle the 65 amps the alternator can deliver you're better off buying a nice inverter and a 130 amp alternator. As anyone that's tried to source them knows, big (high current) transformers are not cheap. As for the alternator it's self, most are going to be be good for a good 50,000 miles or more. If we do some loose math, we can say a car in typical use drives an average of 30 MPH while the engine is running, so that alternator, would last about 70 days of non stop running... at engine speeds. I have no idea what the intended use is here, but pulling the pulley with a string is not going to approach the 4000-20,000 RPM the alternator is designed for. If you had it being spun by a non-geared water wheel, for example, I'd expect the alternator to corrode and fall apart before the bearings fail. Also the regulator/diodes failing is the typical failure mode of alternators in cars, bearing failure is rather uncommon. I'd expect it to last several years at least.
@@johngaltline9933 but if you're in a s*** hit the fan situation it would be a way to have power if you hooked it to a side shaft motor or a creek with a water wheel for a Time or a windmill or something along those lines just a good alternative for power for a short time
I am at a complete loss. The only step up transformers I can find are from dc voltage to ac voltage. Am I correct in assuming that the voltage from the alternator in the beginning of the video is AC? Or is it DC.
🔵 @ (0:17) seconds into the video you state that "An alternator produces DC"..... THIS IS INCORRECT!!! It's called an 'Alternator' because it produces AC ('Alternating-current') which is then rectified by diodes into DC to power the car's electrical systems.
To connect the alternator with windmill what alteration to be done in it. If the windmill rotate in the opposite direction will the alternator produce power? Please explain.
You couldn't find it because there is no such thing. What you want is an _inverter_ . THIS is the device that will change your 12 volt DC to the AC that will be compatible with household appliances.
The residual magnetism is sufficient to produce a small output from the alternator. Then, the output is used to power the field windings, and full power (67 amps) is available, with sufficient mechanical input power.
Most alternators are purposely designed NOT to retain any residual magnetism (though certain types might). They are intended to have power from a battery when being started to initially energize the field winding, then once they are generating they use a small amount of the alternator's output to supply the field, becoming "self-excited."
They've been used in cars to generate electricity for eons now. If you have a car that uses an internal combustion engine, you also have an alternator.

Very cool idea. How can you keep the battery charged? Would a capacitor be better suited in a loop from the alternator since a battery will eventually fail? I have a water fall I'd like to try this on.
Drone Meets Nature: I don't recommend you use this *as shown* as an alternative household power. The output is three phase and your home is MOST LIKELY single phase. To constantly only use one phase puts lateral torque on the rotor and will ware out the bearings very quickly. As a water powered generator you would need to come up with a way to govern the RPM to a fixed value to keep it at 60 or 50 hertz. This would be 30 or 60 RPM depending on how many wingdings are used for output. An automobile alternator is intended to spin at 750 to 3000 RPM to generate maximum amperage. The best solution is to leave the automobile alternator as is and put it's 12 volt output through a 120 volt inverter. If you leave the rectifier on the generator, it is internally wired to supply the exciter coil with current and holds the output to a fixed voltage regardless of RPM. The battery is only used initially when the generator first starts to turn to energize the exciter coil. It is continually necessary here because the regulator circuit was removed. A capacitor could be used to "start" the generator. A car alternator can "start" with as little as 2 volts in the exciter coil.
P.S. there are a rare few alternators that have a permanent magnet coil that supplies current to the exciter coil to initialize the exciter field. These don't need a battery connection at all and are commonly found on gas powered portable generators started with pull cords and some diesel powered generators.
@@3DPDK Thank you for the wealth of information. I will definitely do that.
Do we get higher than 110volt ac by using any other transformer? And video was so helpfull
Yes of course
Yes y not by connecting high excitation & with high rating transformer .
Nice
If you can get 240 volts ac an you tell me maximum current please ? Im trying to do this to run my fridge in a blackout using an electric motor to spin the alternator !any reply appreciated? Thanks
That is the direct connection uses for a testing,buti a common usaged of that features is need diodes,,in a possitive and a negative,polarity from the direct current to the alternating current,must use the degnified rectifier diodes who devides the current into lights and others continously....buti in a way its amazing tuiturials....
This is an old idea I had a device in 1975 that changed the alternator to AC and I used it to build my first house.
Very good it’s helping me
But how much rpm is needed to get 110v without transformer
~ 18,000 rpm for 110v without transformer
Mr Electron , does it work or a car alternator coils get burn due 18000rpm to produce 110v ????
Coils won't burn but brushes will die fast.
Oh!!
Okk thanks brother
But can please tell me how can I save my brushes????
By changing the brush every time or by putting a new brush which is better then it?????
Replace it with new one
I had a kit that I bought in a closeout bin at western auto? Circa 1986. Anyway it was for a Ford specific with all of the goodies on the firewall. And I had a 67 Pontiac. This has been around a while!
Sharing the education and you
Well done so how is that alternator going to be running or am I going to add another motor to it?
You can do that. All that alternator needs is to run.It doesn't matters how you run it
Can a car's alternator to charge 2 batteries at the same time? I was use this method to charge my household power back up battery when I'm driving. Driving and using petrol is just a waste so why not use disposable energy to generate another energy? hope I'm making sense.
Yes it can. You must connect positive to positive and negative to negative. I do this all the time for charging my extra batteries !
Good job sir I like your ideas n your project is really good,can you help me set up a toyota 4 pin,altonator, like a wind mill so once it spins it charge car battery so I could put on a inverter like let's say 300 watts ? Help pls thanks
Nice job you can tell your not a fake like others on here
Thanks !!!
Love you
The shaft speed is 36000 rpm, can you suggest a 3 phase alternator with 50hz 230v ac, or 28v dc . It should be a off the self item.
An alternator produces "Alternating" (AC) voltage. That AC voltage is then rectified and the voltage will now be DC "Direct Current"
Thanks
What about the 110 volts getting from the transformer will only last until you drain the battery??? how you solve that gap??
Frequency match ? If running continue transformer burns ?
Why does it want to draw down and kill the electric motor when I put the positive terminal on the rotor of the alternator it doesn't want to pull it. Can you please help?
Voltage is no good without amperage take that to the bank
Nic idea frnd
How do you hook up the other wires so that the alternater works at it's full capacity?
IT'S NOT A NEW IDEA! The reason there is a voltage regulator IN an Alternator is because an ALTERNATOR puts out 120 volts per coil on the Stator. The Term ALTERNATOR comes from the fact that it puts out Alternating Current, which is converted to 12 Volts DC through a Diode Trio. Ford at one time had Alternators that had 120 volt AC terminal for AC accessories, even today Tractor Trailer trucks have an AC output on the alternator to run accessories inside the cab.. So getting AC Voltage out of an Alternator IS NOT a New Idea by any means. ANY AC Voltage you get off of an Alternator will need a Rectifier/Voltage regulator to keep the Voltage from fluttering and spiking. Lastly, no matter what you do, you still need 12 Volts DC at about 10 amps to power the FIELD on the rotor to get an alternator to produce any kind of voltage.
You said you have removed the voltage regulator bridge, on GM alternators they have a build in voltage regulator , so you remove it too?
You have to bypass or remove the regulator and the rectifier, then tap directly into the alternators stator windings.
Ok, too many “ok”, ok?
You should do videos only saying “ok”... :-)
If you attached it to a water wheel near a river you would have free electricity if it was geared right how many amps do you get out of it and how long do you think the alternator would last at full capacity running 24/7 just curious would it burn up quickly
Yes it will generate good amount of energy. Its designed for continuous operation to it won't burn up.. although the brushes will get used up quick coz of continuous operation. Its a 64Amps alternator
Mr Electron that's 600watts only .a inverter is 29$ better idea.100v _ 6a. Only.
I really doubt the alternator is the limiting factor in this project. That tiny transformer going to be lucky to push 3 amps before it melts. For the cost of a large enough transformer to handle the 65 amps the alternator can deliver you're better off buying a nice inverter and a 130 amp alternator. As anyone that's tried to source them knows, big (high current) transformers are not cheap. As for the alternator it's self, most are going to be be good for a good 50,000 miles or more. If we do some loose math, we can say a car in typical use drives an average of 30 MPH while the engine is running, so that alternator, would last about 70 days of non stop running... at engine speeds. I have no idea what the intended use is here, but pulling the pulley with a string is not going to approach the 4000-20,000 RPM the alternator is designed for. If you had it being spun by a non-geared water wheel, for example, I'd expect the alternator to corrode and fall apart before the bearings fail.
Also the regulator/diodes failing is the typical failure mode of alternators in cars, bearing failure is rather uncommon. I'd expect it to last several years at least.
@@johngaltline9933 but if you're in a s*** hit the fan situation it would be a way to have power if you hooked it to a side shaft motor or a creek with a water wheel for a Time or a windmill or something along those lines just a good alternative for power for a short time
wow it is a best trying but can you show me the bulb comen give lihgt?
I am at a complete loss. The only step up transformers I can find are from dc voltage to ac voltage. Am I correct in assuming that the voltage from the alternator in the beginning of the video is AC? Or is it DC.
Transformers only work on AC, or pulsed DC. Alternators produce AC but the internal rectifiers make it DC.
@@newventure4747 got it! Thanks for clearing that up for me!
whats the application what is going to turn the alternator to run this ?
In your setup the transformer is acting as an "inverter".
🔵 @ (0:17) seconds into the video you state that "An alternator produces DC"..... THIS IS INCORRECT!!!
It's called an 'Alternator' because it produces AC ('Alternating-current') which is then rectified by diodes into DC to power the car's electrical systems.
Why don"t you use a drill to spin the alternator instead of wrapping a cord around the alternator , much easier .
To connect the alternator with windmill what alteration to be done in it. If the windmill rotate in the opposite direction will the alternator produce power? Please explain.
Yes
All you have to do is maintain rpm
et si il n'y a pas de vent, tu produis quoi comme puissance, l'instruit !!
The same battery can as well be used a 12 volt motor to turn the alternator and charge itself a the same time for a continued power
Doesn't work that way unless you don't mind producing less than you consume.
Can u just tap it straight from the alternator without using the transformer???
How can I increase voltage of 24v alternator (required voltage 56v ) ,
Please suggest what I do.....
(I want your contact for more information)
HI ,WILL It WORK IF I HAVE A DIFFERENT TRANSFORM
It will be 400 cycles only run brush motors or resistance loads will fry everything else
How long will it last?
220v at how many Amps ?
It would of been better if you would of told us where we could get a DC to AC transformer like the one you used. I tried searching ebay with no luck.
You couldn't find it because there is no such thing. What you want is an _inverter_ . THIS is the device that will change your 12 volt DC to the AC that will be compatible with household appliances.
Could one generate power from that if he used a motor powered by the generator it's self?
That's not possible.
I've seen it done
What voltage can it produce without any battery power source. Only with residual magnetism.
Depends on the strength of the residual magnetism 🙂
The residual magnetism is sufficient to produce a small output from the alternator.
Then, the output is used to power the field windings, and full power (67 amps) is available, with sufficient mechanical input power.
Most alternators are purposely designed NOT to retain any residual magnetism (though certain types might). They are intended to have power from a battery when being started to initially energize the field winding, then once they are generating they use a small amount of the alternator's output to supply the field, becoming "self-excited."
which type of alternator is this
so the output alternator has changed from DC to AC because remove the rectifier?
yes
Mr. electron how to wire the stator to get the Ac current
Hi
Why are you taping at an angle? does it make sense to you?
Pls make a skematic diagram and specify the number of turn of the magnet wire that you used
Sir how much volts is generated at crank of car and bike plzzz reply
Jesus Christ Loves and Bless all. Amen
Ur late just buy a converter at wall Mart 50 bucks
Sir, how can we charge the battery...when battery is run down...
How much current will each phase supply on the AC side?
Sir tell me about these transformer specification and where from I purchase it please share link for transforms
An alternetor crates ac current not dc bro😅😅
Never heard of a 12V Alternator.
LMFAO! 😁😁😁😁😁
They've been used in cars to generate electricity for eons now. If you have a car that uses an internal combustion engine, you also have an alternator.
