DC BIKE GENERATOR Powering RV Fan Cordless Drill LED Lights Light Emitting Diode
This video shows the power of permanent Magnet motors from DC used in reverse as a generator. The motor is geared so it spins a very high RPMs providing a usable DC current. The Exercise DIY bicycle can power a Recreation Vehicle RV Fan, DC air compressor, cordless drill, LED lights. Light Emitting Diode and Incandescent 50 Watt Light Bulbs. The purpose of the video is to demonstrate the inefficiencies of cordless drill motors and portable air compressors and to illustrate the efficiencies of better constructed motors and LED lights vs regular bulbs.

You are 100% correct Gunnslinger50.
It amazes me how many people make the same mistake.
USE SOME BATTERY
Add a capacitor.
That was great fun! We get to see Denise and Dan umm, screwing, (haha) and hear priceless comments like, “Keep your head down in case the blade comes off.”
10 stars!
All you need to do now is invent the internal combustion engine with the thermal efficiency as a light emitting diode.

5 STARS for the video,
5 stars for the workout!
You might be able to put a sprocket in the chuck on a DC / rechargeable drill. Tap the power output directly from the motor terminals to bypass the trigger speed control circuits. The gear reduction might get the voltage up at a low sprocket RPM.
The drill gearbox might be more heavy duty. Don’t know if the drill motor is very efficient as a generator.
Your experiments & video are great and Denise is just soooo cute!
pretty good demonstration.
That was good, you’ve got loads of nice gadgets there. In case of an emergency, just use your wife as a hamster, hahaha!
I love it Dan. Denise is too cute and is always smiling. I love that you two do things and make these videos together. You two look like you are best friends. I think you’ll be married for life.
I had no idea those RV fans are so efficient. I’m going to have to pick one or two up to replace the 12v cooling fans in my lab. Thanks for the tip! And please keep making the videos. (I love the bloopers too!)
@conicEllipse
they are good used finds. New they cost $130. Older ones like this actually have larger motors and I personally think they are much better made. Check ebay from time to time “USED RV FAN” or “RV VENT FAN”
Thanks for the comment.
Dan
id like to see an air powerd generator as in powerd be compressed air just to see how good it is and if its really possible
I want a Denise generator too
can I rent her to my next job putting up a couple of thousand sqr ft. of drywall
Dan, hook up with your sterling engine. i want to see how much power can sunlight be used with a sterling engine.
Hi Dan,
Great stuff as per usual. Not had time to watch the whole video as yet, but was wondering if it would not be more economical to connect a pully directly to the compressor instead of first generating electricity to run it. To my mind you would be able to store more of your energy as compressed air this way. I’ll watch the rest of the video a bit later to see what else you got up to.
Please keep up the good work.
Always interesting ALWAYS cOOL. tHANKS.
Really nice video as always
… nice team there 
I just have a doubt… is it safe to connect that to for example a laptop or to charge a cellphone? or will it get destroyed if i try?
I have a question, is there a circuit you can put between the generator and whatever you are powering so that if there is a load on what you are powering it wont increase the amount of power needed on the generator. but instead just have whatever is taking the load go slower.
@jazzophis
That would be some sort of a Constant Current source that you need. There are many simple circuits available on the internet mostly using transistors.
Yeah, its about showing whats the right application for such generator. Pretty cool.
I notice one thing. Its a lil bit tiring to pedal, though shes cute when she padal, LOL.
I suggest to put up a heavy flywheel to feel a lil smoother run and lightens the surge current requirement. An Idea.
Thanks for posting great videos
It would be more stable if the alternator is actually on the back side cuz the pull action will do better and easier
@greenpowerscience
hey dan, where could i find geared scooter motors like that?
I have a link on our GPS page.
The more I see the more I’m convinced I need to start working to build an axial flux alternator. I’m not seeing an PM motors that will stand the test of time. Looks as human power is best suited for battery charge. Even as others said a flywheel make that chore less of a chore. A decent video Dan.
How about mounting the pm motor where the rear tire was and finding one with a shaft size that you could mount the 10 speed rear sproket on. Really ramp up the output…..quick charging and easy riding….great vid
i have a sc ooter motor like they have and yes those scooter motors work great for generating electicity , the only trick is you have to hook it up to a capacitor or you will blow your 12 volt inverter up i almost did trying to light up a 14 watt light bulb pluged in 120 volt from a 400 watt 12 volt inverter .
