The second law states NOTHING of the sort and neither does the first or the third. Even if they did they are dealing with ISOLATED systems which means it would rarely if ever apply in this universe.

I'm not really sure what you are attacking my posts for. I tried to give the OP the benefit of the doubt but he has given me no details since then.
Yes I am very aware of the second law of thermo. But its difficult to tell what he is proposing so I believe the second law applies.
As I said before, I believe our laws may be disproven someday. But the burden of proof falls on the person who claims to be able to do so. not everyone else.
Hydroelectric power uses water falling to turn a turbine. He was proposing that the water is in a small closed system. So lets assume 50 gallons. When 50 gallons of water falls through the turbine how is it going to fall again?
Aside from using the energy of the sun and earth like we do in hydroelectric power, we cannot make that water rise to an altitude again without using any energy. If he has a way then I am all ears.
It is possible to patent almost anything. It doesn't actually have to work. there is a patent for a fart gun I saw once. I'm not sure how they have enough pressure from farts but whatever, maybe they have special powers :-)
I do not intende to BS anyone and I don't think I have. I was simply skeptical of an outrageous claim.
You are right, one time I am sure I would have been skeptical that the earth was round. But those that made those claims had proof that made believers of anyone. I wished the OP brought such proof. He didn't however and I am forced to remain skeptical.
I do not share the skepticsim that you do that college students and professers are stuck in the past.
Most question everything, yes they often fall back on theories until new ones are proven. But the graduate students and professors are constantly doing research and trying to prove new ideas and theories. Maybe I misunderstood your point though.
I understood the goverment would certainly take an interest. But what struck me as odd was the OP's concern was greater for the goverment than it was for his idea. He had many people at his disposal ready to help him but choose to place his concerns elsewhere. Me and OP were communicating in encrypted email and he constantly tried to say the goverment was going to intercept his ideas. Not that this isn't possible, but I think the goverment would need some actual information before it attempts to steal anything.

It should be easy assuming you do understand this as well as you claim to.
From what I get you don't believe the laws of thermo?

And i believe exactly the same thing about you. Are we going to deal with specifics or are you content just abusing laws to suit your particular bias?

Well you attack everyones use of the standard definition of the 2nd law.
Maybe it is the real world that application that confuses you.
Yes you provide sources. You provide some questionable sources for your conspiracy theories to discredit accepted scientific theories.
Your posts are generally lacking in any type of information. Mostly just knee jerk reactions to things you apparently do not like to hear.
The standard definition is available on countless websites. If we both are aware of that is it worth the effort of posting it here?

Second Law of Thermodynamics - Increased Entropy
The Second Law of Thermodynamics is commonly known as the Law of Increased Entropy. While quantity remains the same (First Law), the quality of matter/energy deteriorates gradually over time. How so? Usable energy is inevitably used for productivity, growth and repair. In the process, usable energy is converted into unusable energy. Thus, usable energy is irretrievably lost in the form of unusable energy.
"Entropy" is defined as a measure of unusable energy within a closed or isolated system (the universe for example). As usable energy decreases and unusable energy increases, "entropy" increases. Entropy is also a gauge of randomness or chaos within a closed system. As usable energy is irretrievably lost, disorganization, randomness and chaos increase
www.allaboutscience.org...
Applying this knowledge to nature, physicists found that the total entropy change (change in S) always increases for every naturally occurring event (within a closed system) that could be then observed. Thus, they theorized, disorder must be continually augmenting evenly throughout the universe. When you put ice into a hot cup of tea (aristocrats of the Victorian era were constantly thinking of tea), heat will flow from the hot tea to the cold ice and melt the ice in the beloved beverage. Then, once the energy in the cup is evenly distributed, the cooled tea would reach a maximum state of entropy. This situation represents a standard increase in disorder, believed to be perpetually occurring throughout the entire universe.
www.physlink.com...
here are several equivalent statements of the Second Law that rather insightful:
1) During a process, if the system begins and ends at the same state, it is impossible that heat is completely turned into work.
2) Heat flows spontaneously from a hot object to a cold object.
3) The change in entropy is equal to the change in the heat along a reversible path divided by the temperature.
4) The entropy of an isolated system will always increase in a spontaneous process.
The last definition is essentially the one you are recalling.
The idea that entropy is disorder is not quite right and its unfortunate that this concept has been held onto so long.

The law stating that in any chemical or physical process, the entropy of the universe tends to increase.
www.biochem.northwestern.edu...
One way of stating the second law of thermodynamics is:
In any closed system, the entropy of the system will either remain constant or increase.
One way to view this is that adding heat to a system causes the molecules and atoms to speed up. It may be possible (though tricky) to reverse the process in a closed system (i.e. without drawing any energy from or releasing energy somewhere else) to reach the initial state, but you can never get the entire system "less energetic" than it started ... the energy just doesn't have anyplace to go.

The Second Law of Thermodynamics (in Classical Thermodynamics)
Here is how Maxwell explains the second law (Theory of Heat, p. 153).
Admitting heat to be a form of energy, the second law asserts that it is impossible, by the unaided action of natural processes, to transform any part of the heat of a body into mechanical work, except by allowing heat to pass from that body into another at a lower temperature. Clausius, who first stated the principle of Carnot in a manner consistent with the true theory of heat, expresses this law as follows: -
It is impossible for a self-acting machine, unaided by any external agency, to convey heat from one body to another at a higher temperature.
Thomson gives it a slightly different form: -
It is impossible, by means of inanimate material agency, to derive mechanical effect from any portion of matter by cooling it below the temperature of the coldest of the surrounding objects.
www.tim-thompson.com...
What does all this mean? It means that you can't keep all the energy in a closed system for work. There are always losses. Therefore, you cannot get 100% efficiency in energy extraction, much less over 100%.
and here is more on the subject of Entropy and the second law
"Entropy is a measure of the unavailability of a system’s energy to do work."
"An important law of physics, the second law of thermodynamics, states that the total entropy of any isolated thermodynamic system tends to increase over time"
"This means that there is no possibility of an isolated "perpetual motion" system"
- source, en.wikipedia.org...
R: So? What’s your point?
A: That we should be aware that the second law isn’t dominant immediately in all situations. It is short-sighted to concentrate on the fact that energy of the right type and large enough quantity can break or destroy all physical objects. Everything is NOT quickly falling into decay or collapsing all around us because there is some dread defect that is inherent in all matter. There is no "law of disorder" written into the nature of things in the world. It takes energy to cause wood to rot, oxygen and moisture before steel will rust, it takes earthquakes or tornadoes or gravity to make houses collapse or slide downhill. The second law tells what energy tends to do sometime in the future -- and, though I admit that in many cases (like a hurricane!) the future can be only seconds, I think you have to admit that in many cases the future can be billions of years.
Fortunately, because it is only a tendency and not an immediately executed edict, it can often be easily postponed or used to our advantage for a brief time or for a mighty long time.

You may have noticed the words "closed system" a couple of times above. Consider simply a black bucket of water initially at the same temperature as the air around it. If the bucket is placed in bright sunlight, it will absorb heat from the sun, as black things do. Now the water becomes warmer than the air around it, and the available energy has increased. Has entropy decreased? Has energy that was previously unavailable become available, in a closed system? No, this example is only an apparent violation of the second law. Because sunlight was admitted, the local system was not closed; the energy of sunlight was supplied from outside the local system. If we consider the larger system, including the sun, available energy has decreased and entropy has increased as required.
Let's call this kind of entropy thermodynamic entropy. The qualifier "thermodynamic" is necessary because the word entropy is also used in another, nonthermodynamic sense.
www.panspermia.org...
According to the old view, the second law was viewed as a 'law of disorder'. The major revolution in the last decade is the recognition of the "law of maximum entropy production" or "MEP" and with it an expanded view of thermodynamics showing that the spontaneous production of order from disorder is the expected consequence of basic laws. This site provides basic texts, articles, links, and references that take the reader from the classical views of thermodynamics in simple terms, to today's new and richer understanding.

I was trying first to inform someguy and then a few others on the subject matter of free energy, over unity and the like. But I don't see any reasoned, intelligent responses coming from someguy or stellarx.
The laws of thermodynamics are firmly established.
They are used to design devices THAT ACTUALLY WORK all the time.
The laws have been proved beyond any doubt. The burden of proof that these laws somehow do not apply to our universe rest with those making such outrageous claims.
The End
