Hello,
    Power Multiplier Device.
       There are two large sprockets (top, bottom) connected by a main chain. Pull the chain and both sprockets turn.
  On the axle of the bottom sprocket there is a transmission with a generator attached to it. Pull the chain and the transmission/generator turn to produce electricity.
  On the inside of the chain (in the middle) there is a drive sprocket, with two idler sprockets (above and below) on the opposite side of the chain to hold the drive sprocket on the chain.
  There are two plates on the sides on the chain having the axles of the three sprockets going through them to keep them in place.
  On the axle of the drive sprocket that has extended outside of the plate, there is a large wheel that also has a chain around it, with a small motor to drive it. The small motor turns the large wheel, turning the drive sprocket which shares it's axle, causing the drive sprocket to climb the main chain. The ratio is 10:1 where the small motor exerts a 200 pound pull on the large wheel's chain, causing the drive sprocket to climb the chain, taking the whole assembly with it weighing 2000 pounds. The leverge of the long radius of the large wheel allows this to happen.
  Three things now happen:
 1) The energy drawn from the battery to run the small motor to get  the assembly to climb to the top can be valued at 1N.
      EE/up = 1N  (energy expended going up). The ascent takes 3 minutes.
 2) As the assembly is climbing, it's weight is hanging/pulling on the main chain so that it is charging a full charge into the battery,
     helping to replace a portion of the energy being drawn out by the small motor. EG/up = .5N (energy generated going up).
 3) When the assembly gets to the top the small motor turns off. The whole assembly begins pulling the main chain down to the
     bottom, taking ten times longer to go down than it took to climb up. This is due to the substantial weight of the assembly, and
     the low gearing of the transmission to bring the assembly to creep down, taking 30 minutes to descend.
     After the first 3 minutes of the descent, the generator has already charge another .5N into the battery replacing all of the 
     energy lost during the ascent. The remaining 27 minutes of the descent is charging energy into the battery that is not needed   
     to operate the mechanism. This is nine 3 minute periods, or 4.5N amount of extra/free energy to use for whatever.
     EG/down = 5N  (energy generated going down).   EE/up < (EG/up + EG/down) = FE  or,  1N < (.5N + 5N) = 4.5N FE.
     A 2000 pound pull will generate more energy than is required to produce a 200 pound pull.
                                                                                                                             Thank you,
                                                                                                                                             Russell Lee
