    Engine Oil Water
AI Thread Summary
The McLaren oil in water engine concept fails due to the principles of hydrostatic pressure and energy conservation. Water will flow from the higher pressure side to the lower pressure side, equalizing levels in both columns. This movement results in no net energy gain, as the system lacks a continuous energy source. Additionally, the design inherently violates the laws of thermodynamics, particularly the conservation of energy. Therefore, the engine cannot function as proposed.

TL;DR Summary
Impossible oil in water engine, but can anyone explain why it cant work please?
Here we have an oil engine. Oil is fed in at the bottom of a column of water, rises up and collects at the top of the column, it overflows into an adjacent column which could be of larger diameter, and is fed back into the column of water. I know it won't work but can someone please explain why not?

Welcome to PF, where any mention of perpetual motion will probably see your thread locked.

The hydrostatic pressure at the bottom of the water column will be greater than at the bottom of the oil column, so water will flow down and across into the oil column, until the water level is the same on both sides.

There is no source of energy to keep it going.

We don’t discuss perpetual motion machines here.

It cannot work because it violates the conservation of energy.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
