A machine to convert gravity to mechanical energy # 2

I already told you what is wrong in your thinking. A weight cannot expand a cylinder sufficiently to cause buoyancy. Simple as that.

In order to expand the cylinder the weight has to be at least as heavy as the water it seeks to displace. You cannot displace 10 kg of water with a 5kg weight.

You probably don't know this, 1 liter of water weighs 1 kg at 4 degrees centigrade, a little less at other temperatures, lower or higher.

Dear Mr. Rat2,
Even a fifth grader  can understand why the machine you cite  won’t work. In each cycle the machine has to lift the water from the bottom to the top. You gain nothing.
Can you explain why MY machine won’t work? What phase won’t work?
It should be easy to explain why MY machine won’t work.

Sorry Brian, my link was in response to TinselKoala's picture.

Dear Hans,
Not true - you can displace 10 kgs of weight with a 5 kg weight moving  at a high rate of speed.
Like I say Hans you don’t understand my machine. That is a true statement.

@brian334,

Here is what I can't wrap my head around.  I understand that you expect the cylinders on the weighted (dropping) side to accelerate and increase in kinetic energy due to gravity.  The cylinders on the lightened (rising) side must also accelerate and increase in kinetic energy due to gravity.

So each cylinder is moving at a different speed.  How could they all stay together as in the diagrams?

And at the bottom each cylinder must stop.  Because the kinetic energy in the weight is what makes the cylinder expand, right?  So it must begin to accelerate from a velocity of zero again. 

I can't see this working as in the diagrams.  Maybe a sim or animation would help?

Ok Brian, your machine will work. 

But then... no-one will build it because no-one thinks it will work???  So unless you build it yourself, it definitely won't work.
