I would like to make a pendulum go on moving by a permanent magnet that pushes the pendulum back with a force that is big enough to make it swing back with the same height. Can anyone tell me how much energy could be generated by a pendulum with height is 2 meter and 60 kg, swinging 90 degrees high on both sides. Imagine a swing in a theme park. How much Watt can I produce per sec (=Joule). If I go on swinging for one hour: can I multiply the energy by 3600? I used the formula
E=mgh= mgl(1-cosA)=60*9.81*2(1-cos(45))= 558 Joule (Watt/s). That means over 2000 kWh? Probably I make a mistake :-)
