A machine to convert gravity to mechanical energy # 2

Kola,
Does 2 + 2 = 4 or,
Does 2 + 2 = 22

By your way of reckoning,

2 + 2 = 6

because you are trying to add one of your 2's twice.

2 + 2 = 4, the question is where do the 2’s come from? I say you can get them from gravity.

1. The free falling tanks in the continuous column are not attached to the track.
The free falling tanks in the continuous column are attached to each other.

2. The tanks are abruptly stopped at the bottom, when the tanks are abruptly stopped the 65 lb weight keeps going.

3. The external water pressure at the top would be sufficient to push the piston back into the tank.

How can the falling tanks be attached to each other in a continuous column?  That would mean all the tanks on the falling side are going the same speed, ie. NOT accelerating.

The "continuous column (that) are attached to each other" must be going the same speed as the tanks on the pulley at the top of the system.  But those tanks are supposed to be collapsing.  How do they do that?  Do they a)  collapse and leave a gap between each other the size of the collapsing piston, or b) move closer together as the piston collapses?  If you answer "a", then they are no longer in a continuous column.  If you answer "b", what moves them closer together?

Now the tanks on the upward rising column cannot be attached to each other, right?  Because the bottom tank in that column is moving at a vertical velocity of zero, having been stopped for the expansion process to occur, right?  So attaching anything to that tank would mean all the tanks stop, since it is effectively a zero velocity anchor.

Mond, I don't think Brian is actually reading our posts.


Brian, if the free-falling tanks aren't attached to the track, how do you get any "gravity" power from them? How fast do you expect them to fall, since they are just barely heavier than the water they displace? When the tanks stop abruptly at the bottom, the whole column must stop too, since the tanks are attached to each other. There goes all your momentum. The next-to-the-bottom tank only can fall one tank-length from its stopped position (waiting for the tank ahead of it to be expanded) to the position where it in turn will be expanded. Where's the momentum you were going to use? It's not there.
