12 times more output than input, dual mechanical oscillation system !

[tagor]

So, because paths passed by the weight and path passed by the fingers were almost the same and because the weight was 80 pounds and force of the fingers was less than 20 pounds, it should be obvious that output energy was 4 times bigger than input energy."

it is not science !
it is ridiculous !

the less you can do is , measuring the works done by the finger
when a real work is done ... for example lifting 80 pounds not up and down
but lifting 80 pounds UP : 1 meter ?
can you think to do this real work ?

@ tagor

I do not post here often but I do keep up with the thread.

To make science out of it, I think the obvious approach would be more in line with the following.

Measure actual input force (torque) in foot pounds from pendulum pivot to point of hand position X time applied.  Measure the raising of the 80 pound weight X distance X time. From this a mathematician can derive horsepower in and horse power out!

Now whereas the weight has been allowed to fall back deduct what you just allegedly gained.

The fact that a boy can lift 80 pounds by applying 20 pounds
without measuring the other factors is not an objective conclusion, therefore I agree, it is not science.

An 'after thought'
Lets say our 80 pound weight is a square 10 X10" resting on a bellow of the same dimension compressed 2", calculate the psi. The bellows are spring loaded to allow raising as the weight is lifted, They are pneumatically connected to a pulse or slave cylinder. Upon opening (up stroke of main weight) the spring action not only opens the master bellows but pulls the slave cylinder back to its start position. 

How many psi using the above factors would be created in a slave (pulse) cylinder of say 1=1/2" in diameter with a 10 cm or 4" stroke?

The spring loaded bellows could be attached to the bottom of the 80 lbs.weight, and the spring removed allowing even less resistance to fall and compression.

tagor be honest here, when you lift an 80 pound weight up and then let it fall down again, you have done real work! I cannot understand how it could be otherwise. If he had collected the energy from the weight's height, by oscillating it back into the pendulum somehow and making it land slowly, yes then it would not have been real work, but as you can both see and hear, he let if fall straight down....

Are you arguing against this scenario or is there something else behind you accusations?

tagor be honest here, when you lift an 80 pound weight up and then let it fall down again,

you are totally wrong
it is not real work => it is equilibrium , there is no work , COP=0
