Is it at all possible -- at least in theory -- to violate the second law?

Default Is it at all possible -- at least in theory -- to violate the second law?

Hi:

Is it hypothetically possible to successfully perform an activity that
violates the second law of thermodynamics?

Lets says I have a supernatural device that can stop the second law from
existing anymore simply by pushing a button on it. What will the
universe be like after I push the button?

Thanks,

Radium


Yes. There are many examples on large scales.

There are autonomous processes such as floating in space. You push an
object and it moves forever. A perpetual motion condition.

Let's expand on that. Relativity exists. One needs to think in the
world of Einstein.

There are many other cases that open doors for autonomous conditions
by initiating change and setting an autonomous long course, even one
where energy can be extracted.

For example blow up an air balloon 10 kilometers deep at the deepest
ocean point.

That balloon will move up toward the surface autonomously for 10
kilometers.

Once it's at the surface, release the air from the balloon and tie a
rock to it. It will sink back down. To release the air and to place
and tie a rock to the balloon takes very little energy.

Focus on keeping the process autonomous at all times.

The problem: inflating the balloon at the bottom of the ocean at 10
kilometers depth. There is so much pressure there that a submarine
made of the strongest metals crunches in. If metal can't hold the
pressure there, how can one expect a little balloon to inflate? Air
will be shrunk to levels that the rubber on the balloon will not take
the pressure and pop.

There are biological processes that produce gas. The balloon sinks
with the rick and slowly inflates at the bottom at the ocean and
brings the rock back up, then releases the gasses and sinks back down
and the biological process of producing gas repeats.

Once inflated, there is work that can be extracted from the balloon
moving up, and there is work that can be extracted from the balloon
sinking down. Only states change and there is autonomous motion that
follows between intaking gas at the bottom and releasing gas at the
top. When in up or down motion, the process is autonomous, no energy
is needed to keep that motion.

Now let's find a way to inflate an object with gas, a process that
uses little energy:

The only significant energy needed is to convert fluid to gas at the
bottom or find a chemical/biological process that produces gas, say
from fish fart.
Attract the fishes, feed them and make them fart.

But generally a metal broiler will produce sufficient boiling with a
few hundred watts of electricity.

Such processes work because there is no energy needed in making the
balloon rise or sink for long distances and one needs faily little
energy to boil water and produce gas for rising.

Skeptic? Sure, law-laterals are blinded imperialists. Remember
Einstein.
