Magnetic String Power

[finster]

I recently tested what I call a "string motor" I thought of myself. It consisted of a spool of fishing wire with short ferromagnetic beads of string (like those in dog tags) attached at 1" to 1/2" inch intervals along the string...I placed a strong group of magnets on the floor and fed the string into the magnets standing above it...It pulled the string to it's "end" (not the whole reel yet) with no difficulty thus spinning the reel and theoretically generating electricity.

 

Questions:

 

Can a spool of string be made simultaneously small (compact, light) enough but the string long enough to produce a usable output of energy generation?

How strong does a magnet need to be to pull a reel miles long?

How much energy is produced and how much energy did it take to wind the spool?

 

I would be willing to bet that the 2 (at the very least) cancel each other out

You might be right but that's not the point. If (IF!) the spool can be unwound using a Neodymium permanent magnet, it can be rewound using another magnet in the opposite direction. So your point wouldn't matter, would it? (It takes energy to process, refine and deliver gasoline. It's takes energy to build hydro electric plants to harness hydro power.) So?

 

The string would unwind into a special box or enclosure with the magnet on the outside but its force of attraction reaching into the box to pull the string. Once the string is fully unwound in one direction, a shield is introduced between the magnet and the box and the magnet is retracted. A second magnet on the other side of the device is then deployed and the whole process starts over in the opposite direction.

 

Now! The challenge is to find a material for the string light enough, thin enough and simultaneously strong enough to fit miles of it on the smallest spools possible. We want the magnet to pull the string with as much force as possible but we want to be able to load so much string on the spool it will take hours, hopefully days to fully unwind in one direction before the polarity has to be manually changed like filling up a "gas tank".

 

It works on the same principle as solar energy or hydro energy except we don't have to wait for a sunny day or depend on the rain to fill up the reservoir.

 

We control the "fuel" because the "fuel" is entirely man-made and also clean. It works on a cloudy day. It works during a drought. It's like a kinetic battery. But no chemicals. No pollutants.
