Could this water/air reciprocating machine work?
« on: 14/03/2016 22:50:02 »
mike flanagan asked the Naked Scientists:
   Water/Air reciprocating Machine.

Can this machine work?

Components:
a)  A volume of water
b) A volume of compressed air

Important properties of the components:
a) The water weighs more than the air
b) The air exerts a higher pressure than the water

Can the machine work like this? :
1. Compressed air forces the water to a higher level.
2. The water then falls to a lower level because it's heavier than the air.
3. Go to 1.
What do you think?

2. The water then falls to a lower level because it's heavier than the air.

There is a  contradiction here. In step 2, if the water is heavier than the air (pressure), then step 1 will not work.

This appears to be a proposal for a "Perpetual Motion Machine of the first kind": a machine that could be used to produce electricity (for example) without putting in any additional energy.

Such proposals appear with great regularity. The patent office takes the approach that no such patent application will be accepted unless it is accompanied by a working model. ie the default assumption is that the idea is flawed.

The above link also provides some common reasons why such proposals fail.

What do you think?
What is your source of compressed air?
If you are relying on the water recompressing the air it won't work due to losses and the fact that the air will only be recompressed to an equilibrium level.
