Hi All, just thought I'd throw an idea I had into the ring. First off, cheers to execelon7 for the diagram that I modified slightly - if I make a million of the design, I'll cut you in

I've been thinking about generating electricity with alternators too, but why stick with 1? But, I hear you shout, the more alternators, the more friction to overcome - but what if the gears / belts are replaced with magnets? - I'm sure there will be some resistance to get over - but not as much as a chain / belt.



The positioning / number of alternators as well as the positioning / number / type of magnets on the flywheel / alternators would be the trial and error bit to be worked out to get the best configuration. I've shown the magnets as Neodymium, but these may be too strong - so this would need to be another vairable. I would start with 1 alternator, and 1 magnet, and add more magnets / alternators to the setup, untill I had enough power (can you have enough Mwaaaahahahaha) or until the output started to drop off.

Next bit would be why use standard alternators? - This site is selling revamped alternators that are much more powerful - YouTube (I'm not associated with the site btw)

Couldn't find actual figures for output, but i'm sure I heard 1000w(?) mentioned in 1 of the videos. I also see some of the comments in you tube saying that it can't be used in cars because of the unregulated voltage - possible to put an external voltage regulator onto it?

So 1 idea, 2 technologies several questions that would need to be answered to make it work, and a diagram ripped of from someone else (thanks again execelon7)

What do others think?

The more power you try and pull from an alternator, the more difficult it becomes to turn the alternator. Really! Try it! Start a regular ICE car, remove the battery (Short the battery leads), then turn on the high beam lights and rear window demister, and listen to the engine bog down and struggle as it has to turn the alternator with the increased load.

Me2!

I love how the first thought that comes to a physics liberated mind is always "It's such a great idea, why stop at 1? Why not 2 or 10 and generate that much more power?"

The iPod crank charger came out years ago and the immediate suggestion was "They should put more plugs on it so one person can crank and charge 10 phones while they're at it."

That's the beauty of overunity, you don't need to produce 2x the input power, but if you're the genius who finds out how to get 1.01%x the power out you can have infinity power and rule the world!!!!

Thank you for your comments. We need to look forward and use the past as a reference point not as fate. I think I have found a flaw in the 6V experiment listed above. I am going to buy a couple of motors like the member said but reverse one of the motors to see what happens.

If an electric motor is running optimally when it is unencumberred by anything attached to it, then the real issue is torque, just like in an ice. If the theory that torque is optimal at high RPM's through gearing is correct, than wouldn't the simple machine principles pertaining to levers and pulleys apply? With the right gearing ("levers and pulleys") in place, less energy or force is required to move larger, heavier objects, i.e. "perpetual motion".

Less force is required over a longer period of time. To get a full revolution out of a bike wheel, you can turn it with nearly no force from the outside, but you must turn the full radius. To get a full revolution near the hub will take more force for just a few inches.

A similar amount of power is used in either case.

Agreed. And like a 10-speed bicycle, if the rider exerts the same, even flow of inertia while "clicking" up through the gears, the result will be increased speed and improved energy efficiency. (Hwy vs. city mpg).

Another way to look at it is that you have a 1-ton weight that a single, 150lb man logically has no chance of lifting or manuevering by himself. However, if the same man applies the appropriate, proven principles of leverage (levers, pulleys, etc.), the 1-ton weight ends up being at the mercy of the same man's intent.

sure, torque is different, and so is the speed..... but it's the same amount of work.

I can't believe you actualy have a 10 speed bike. I believe these strange views of reality are caused by a lack of biking. In the Netherlands you hardly ever, more like never, hear people think that gearing can increase anything, let alone create energy. You really must bicycle more.
