Readers, "entropy potential" is not a scientific concept.
Water and oil emulsions tend to separate as a simple result of lowering their enthalpy, by reducing the surface area, since molecules exposed at the surface are in a higher energy state than those within the body of the liquid. There is always a trade-off between the effects of entropy and enthalpy in chemical processes. (As any other chemists here may recall, ΔG = ΔH - TΔS.)
Well-wisher has had bees in his bonnet about water, entropy, hydrogen bonding and liberals (spot the odd one out) for years, on a number of forums I have participated in.
Entropy potential is an engineering concept, that I developed, based on lab observations and easy to run experiments you can do at home.
For example, osmosis is colligative property. A colligative property is a property that is only dependent on the concentration of solute, but it is not dependent on the chemical character of the solute.
In other words, in osmosis, negative or positive ions, with one or more charges, as well as neutral molecules, will all generate the same osmotic pressure, as long as the concentration is the same. Since charge does not matter or have any impact, osmotic pressure is not driven by the EM force. Instead, it is driven by entropy.
That being said, I can generate an entropy based potential; entropy potential, to suit my needs, by simply adjusting the concentration on one side of an osmotic device. There will be a time delay, but the water will accommodate my needs and generate a final entropy pressure=force/area, that I can calculate and predict, even before I get started. I call this entropy based force, the entropic force, since it is created by entropy. This is also a term, I invented, that is very descriptive of what is occurring. It is a fifth force of nature, used by life.
There are also other ways to set up a predictable and directed entropy potential. This is based on knowing that a system will seek a certain level of entropy, to meet the needs of an equilibrium environment. I can locally reduce this entropy, and it will express a fixed potential, as it restores equilibrium. Water and Oil works this way but with a twist, due some unique properties of water.
Water forms hydrogen bonds, while hydrogen bonds have both polar and covalent bonding character. The hydrogen bonds of water, act like a binary switch, which can go either way, based on the conditions. This shows up as low and high density domaines in in water. The polar side of the switch is denser and has higher entropy, while the covalent side of the switch is less dense and has lower entropy.
When we have an emulation of water and oil there is a lot of surface tension in the water. Tension means stretching, which is implicit of the covalent side of the water switch; less dense. This stretch hydrogen bond defines lowered entropy. The phase separation, back into two layers; oil and water, by lowering surface tension f the water, is flipping the switch to polar. This increases the entropy of the water; second law, on top of the enthalpy change. This extra drive allows water to man handle and set an entropy potential within the organics. Now there is potential to increase entropy. Enzymes only work in water since due to the binary switch affect unique to hydrogen bonding plus the four hydrogen bonds of water. Ammonia cannot form as many hydrogen bond with itself so the affect is much less.
The water and oil affect in cells lowers the free energy of the water via both entropy increase and enthalpy decrease. The organic; oil, lower enthalpy, but also lowers entropy. The result is a global entropy potential on the surface of all the organic structures. This is the basis for life.
