i have an rc car here and when i drag it with my hand from back to front the rc car back wheels some how lights up the from led light in the car bonet.

now can i use this motor in that rc to re-charge a battery ?.

on a drone their is 4 motors and is their a way i can use this device from rc car and add it so as the drone motor spins so fast it charges the battery ?.

what good stuff can i do with this

You can't get something from nothing. It takes energy (pushing up hill) to recharge the battery. The process of providing energy (discharging) from the battery to the wheels or props is a loss. (rolling down the hill) If you're at the bottom with a discharged battery there's nothing left. The small amount of energy provided by your hand is unlikely to be useful.

What you're talking about would be called a perpetual motion machine if it worked...but it doesn't work. If all motor and generator and battery charging efficiencies were 100%, you could break even on stored power, but none of those processes is 100%. efficient. You just can't generate any useful power without using nearly twice that much power to generate it.

when dragging the rc car with hand the head lights of it lights up thier must be something maybe the motor generating the power , so cant we store that power.

the drone has 4 motors and some how attach that feature to the drone motor so when the motor is running fast it should generate power ,and have it charge the battery ?

Wow, thats a great idea! All you need to do is to keep pushing that RC car and it will eventually charge the battery. Same with the drone. Just wait till the next hurricane and hold the drone motors into the wind and it will charge the battery. Let us know when they get a full charge, won't you!
 
You want the motor to charge the battery that is causing it to rotate?

Keeping it simple...

The r/c motor can work as a motor or a generator. The motor requires electrical power in to get mechanical power out by rotating.

The generator is the opposite, if you put mechanical power in you can get electrical power out.

yes so the rc drone motor is geting power from the battery and that makes the blades spin , so the rc car i have when u drag it the led lights light up this mechenism in the rc car that lights the leds up can that be impliminated in anyway to charge the drone as the drone blades spin hope am clear.

or

can i generate power to light led lights up ? using the rotation power of the drone blades or motor

what about
Energy Magnet Motor
can that be implimented on a drone to get the led lights to light up free
 
You can possibly generate enough power from the rotation of the drone blades to light up led light. Unfortunately, the drone will be sitting right next to you while you spin each of the motors so they are acting as generators.

You can not use the r/c motor both as a motor and generator at the same time.

the energy magnet with the air it will start to spin wont that light the leds up ?.
i se on youtube the spin it and the fan turns around and led lights up or a house light bulb

The Youtube Energy Magnet Motor is a stupid scam or joke.

Don't go there please.

This is where the problems begin.

Heed those words. There is no free. When you run a small DC motor it uses energy and if we rotate that same motor backwards it becomes a generator. A generator takes energy to run so really we are trading in this case mechanical energy for electrical energy. Believe me I tried getting something for nothing and there is no "free". :)

i se on youtube
YouTube can be a great place to learn new things and find ways to solve problems. HOWEVER - there are people on YouTube that get paid for their videos. So it behooves them to produce something that will attract a lot of attention, such as magnetic motors and free energy devices. The problem is that they're all hoaxes. You watch - you believe - they get rich and you get deceived.

What we're telling you is that in a perfect world a motor could spin a generator that powers that motor. Only on YouTube can you find a motor that powers a generator that powers that same motor AND several other devices. It's just the laws of physics - THIS CAN'T BE DONE!

Sure, when you push the car the lights light up. You're using mechanical energy - your hand, your muscle - to push the car, spin the motor and it acts like a generator. The amount of energy to light the LED is the same (not fully the same) as the energy you expend pushing the car. Go push a real car. See how long you can push it before you're exhausted and need a rest. The bigger the car the quicker you tire out. YOU are using energy to create physical motion. In your RC car you're using your physical energy to spin a motor that in this case acts like a generator. And no, you can't take a 12 volt motor and use it to spin a 24 volt generator and use the output to spin the motor. IT JUST WON'T WORK! Trust us on this. Some of us are smart enough to know this won't work. Others of us may have tried this and found out that it doesn't work. So stop wasting your time thinking you can do what can't be done. Genius' haven't been able to figure this out. And I'm talking Einstein's and Tesla's. The case has been made, this CAN'T work. And at best, in a perfect world the best you could hope for is to run a motor and generator that sustain themselves. As SOON as you put an additional load such as a light - be it a light bulb or an LED, the extra load will stall the system. That's in a PERFECT world. In the real world you have drag, heat loss, resistance in the wires, and then the light you're creating from the LED. It just won't work.

That's all from this peanut gallery.

I would be in the latter group. When I was about 10 years old I had this big interest in automotive batteries and generators. I say generators because in 1960 cars had moved from 6 VDC to 12 VDC systems but still used a generator. I quickly made the astonishing discovery that when a battery was connected to a generator the generator became a motor but ran backwards. I presented this marvelous discovery to my dad who was an EE and he wasn't impressed and handed me a book to read. I knew if I could take two generators and use one as a motor and one as a generator with the drive belt and the motor / generator opposing I was into something. I found an old V belt and cut tire inner tubes to hold down my parts on a board and yes, automotive tires still used inner tubes and these inner tubes were also great at the beach. I met with dismal failure and today 57 years later my father's words still echo in my head, "Ronald, you can't get something for nothing". It wasn't till later in life and my education that I understood things like loss but dad was right and I learned the hard way. Hey, at 10 years old plenty of stuff looks good on paper right till.... :)

When I was seven my dad bought a gasoline powered lawnmower. I just HAD to know how it worked. So I took it apart. Dad wasn't too thrilled with that; but at least he took the time to explain to me how everything worked. Then I put it back together - few bolts in the wrong place - learned about torque and aluminum blocks, and cut the grass. AT SEVEN! Since then I've been a gremlin. Having to understand how EVERYTHING works. I've taken so many things apart in an effort to discover how they work. I've made a lot of really whacky inventions too. When 14 I got a mini-bike. At 15 I built a supercharger for it. The darn thing worked. We swore it was more powerful and faster, but it probably wasn't. Kind of like when you wash and wax your car it just drives better.

I remember generators in cars. 64 Corvair had one. I messed with that thing, and like you, I discovered that reverse connections made it run backwards. My dad explained that back in the day the generator was also used to start the engine of some cars. That was a long ways away from todays push to start cars (push the button I mean).

I also used to believe (age 7) that if you could unplug an extension cord from the wall and plug it back into itself fast enough you could trap the moving electricity, and then plug in a lamp and it would work. Of course nobody could unplug and plug a plug into itself that fast. And if you COULD - supposing the theory was correct, that you COULD capture the current in a looped extension cord, the resistance of the copper wire would quickly dissipate any stored charges. Today we know that's not true. Probably every adult also knew that way back then. But to a seven year old child - anything COULD be possible. Like a focused magnetic beam used to propel a car or an airplane. Or running an entire house off of a single 9 volt transistor battery. Back then I didn't even know WHAT a transistor was. I thought it was some sort of battery. But now I know back in the day it took 9 volts to operate a transistor radio.

Funny how we learn things.

I drove one of those, "Push to Start" cars to my high school graduation.:D
It was an English Ford Anglia. Push to start, jump in and pop the clutch, and drive away.:)
It also had a one speed carburetor. It idled at about 1800 RPM, which was enough to get to 30 MPH, which was sufficient on the residential streets of Indianapolis.:rolleyes:
That one lasted about a month, then I traded up to a 1948 Ford pick-up truck.:oops:
I'm telling you, life was great when you could by $50 cars any time you needed one.:p
