As per sketch a 2 meter long tube is mounted on the left arm of a seesaw and this see saw is balanced due to counterweight.there is a 10 kg mass ball located in the in rest position in the tube.
See the link.

Now seesaw is balanced at 180 degree angle.when I tilt it this balanced seesaw then the ball fall down from 2 meter height and hit with upper part of tube .but interesting after hitting the seesaw will get back it's initial position without any external influence.so ball will again fall from 2 meter height.in this way the ball will fall down twicely but the main interesting point is that the input energy is almost zero as there is no torque due to counterweight.
There will be a lock mechanism to prevent the falling of counterweight at the time of tilting.
The ball will fall down after getting a certain angle as a pin will work to hold the ball to prevent it from sliding along tube at the time of tilting.
If there is no energy as a input as seesaw is balanced and torque is same then output is ,using mgh formula
Mgh= 10*10*2=200 joule at the time of tilting.
Mgh=10*10*2=200 joule at the time of reversing.
So total output is 400 joule but input will be almost free due to equilibrium position of seesaw.
Input will be very minimal due to counterweight and equilibrium position.
