In this sketch you will find that I have attached 10 shake flashlights(coil+magnet system) on the both side of a balanced seesaw system and this seesaw is moving with a motor but I have used 10 no. shake flashlights . If we try this concept than input is more than output but if we add total output then it is greater than input.These flashlights or coil+magnet system will be mounted permanently in horizontal direction and this seesaw will move side by side. please answer me that will these flashlights will be light up or not as mass is not an issue in this device. Note(1)each flashlight is separate with another flashlight . (2)to move a balanced seesaw there is need of less energy or input The design is simple and there is nothing complex to understand the design .suppose there is a BEAM which is in equilibrium position and 10 no. coil+magnet system or (flashlights) permanently attached on it horizontally and we are turning this seesaw side by side towards 2 to 3 centimeter.you can imagine its function very easily. To turn a 4 kilogram (including mass of flashlights) balanced seesaw in 3 centimeter(thrice a second) there is need of only .36 newton force using f+ma equation ,there fore I say that mass is not a big issue in this design even we can reduce it upto 50%more but the main issue is sliding of magnet to move pass the coil. Suppose a coil+ magnets system require 10 watt to shake so that it could counter the Lenz's law then this 10 watt + .36 watt(newton)+ .50(watt) = 11 watt will be sufficient to shake all 10 no. flashlights or coil+magnet system.if a coil +magnet system 's output is only 5 watt then we can get 50 watt out put with these total 10 no. coil+ magnet systems and input will be only 11 watt.That's what I want to say. furthermore if we replace coil+magnets with 10 people then these ten people will move or turn when we will shake or turn the arm of seesaw. when this 11 watt force will applied on the arm of seesaw then every coil+magnet system will work as this 11 watt will be equally distribute in all these coil+magnet system. if mass is equal then F=a and its mean that the force applied on seesaw will be distributed equally or in other words all flashlights will be accelerated equally.Thus each flashlight will generate energy and output will be greater than input. Note: we are turning the corner of seesaw so total system will be turned . we are applying input energy but this will be distributed equally to shake all 10 coil+magnet system. There is no need of applying 10 times force as only one time force will be sufficient to shake the total 10 no. flashlights.
