Why Doesn't the McLaren Oil in Water Engine Work?

The oil engine relies on hydrostatic pressure to function, but without an external source of energy, the system will eventually reach equilibrium and stop working. This type of perpetual motion machine violates the laws of thermodynamics and is not possible.

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.
 

FAQ: Why Doesn't the McLaren Oil in Water Engine Work?

What is the "McLaren Oil in Water Engine"?

The "McLaren Oil in Water Engine" is a revolutionary engine design developed by the McLaren Group, a British automotive and technology company. This engine uses a unique oil-in-water cooling system, where oil is mixed with water to cool the engine components, resulting in improved performance and efficiency.

How does the "McLaren Oil in Water Engine" work?

The engine works by circulating a mixture of oil and water through the engine's cooling system. The oil absorbs the heat generated by the engine, and the water helps to dissipate this heat through the radiator. This allows the engine to run at a more consistent temperature, improving performance and reducing wear and tear on the engine.

What are the benefits of the "McLaren Oil in Water Engine"?

Some of the main benefits of this engine design include improved performance, increased fuel efficiency, and reduced emissions. The use of oil-in-water cooling also allows for a more compact engine design, freeing up space for other components and reducing weight.

Is the "McLaren Oil in Water Engine" available in all McLaren cars?

Currently, the "McLaren Oil in Water Engine" is only available in select McLaren models, such as the 720S and 570S. However, the company plans to implement this engine design in all future models, as well as potentially licensing it to other manufacturers.

Are there any drawbacks to the "McLaren Oil in Water Engine"?

While the "McLaren Oil in Water Engine" offers many benefits, it also has some potential drawbacks. The main concern is the long-term reliability of the oil-in-water cooling system, as any issues with the system could lead to engine failure. Additionally, the use of oil in the cooling system may increase maintenance and repair costs.
