I live in the tropics, and are plagued by frequent power outages. Tap water contains approximately 28 degrees Celsius and sometimes I can fill my bathtub with it and create cool when the fans and the strike aircond and sweat too much. When out of the tub, I can not always escape, because once again take a cold bath for a couple of hours later, or even wait for the next day. When the next day, shows that the water in the bathtub has become very cold, much colder water from the tap. Why nothave high air temperatures to see how we can provide the heat of a warmer environment? I lost my sweaty body, the same question, how can my body is cool to room temperature, which is the same or even higher than my body temperature?
The answer is, obviously, needs to evaporation, the heat also causes the flow from a cold to a warmer regions. It has been known for thousands of years and practiced by water and wine into glasses of fresh material porousand part of the liquid to evaporate. So if you ever believed that heat flows spontaneously from a cold to a warmer region, go to the tropics and the experience that this is not true.
However, you were probably taught in school, but then your teacher is not the second law of thermodynamics, which states that heat can flow from a cold to a warmer region, with no other effects to explain.
Other effects in my bathtub and the body are safe there. If IThe recovery of the water evaporates, it will be my last tank empty and my body will die. All this has to do with entropy, and if you do not know what it is, read my article: "What is entropy" for an explanation.
We are now taking a saturated vapor at room temperature in an expander, which is about a lower pressure and temperature and contains a certain amount of cold gas as cold liquid and expand. This is basically what a steam engine, where the residual gascondenses into water, and also shows that the input power, heat and condense the vapor condenses back to a use and a lot more than the mechanical power supplied to the expander shaft.
Since the days of James Watt, hold down the size of the engine must operate at full steam pressure not to expand the steam. Even in our modern steam turbines, the expansive force of steam is not used (the thermal energy is converted into kinetic energy, instead). However,Experiments of James Watt, with the expansion of saturated steam and from the results that make it documented, I discovered that the force is developed is almost the same as needed to clear the extended blend recompressed to its original condition steam. My calculations indicate that the same applies to ammonia vapors, and this is probably true for all saturated and wet steam.
This would give us the ability to convert heat (from combustion) to mechanical power at very highEfficiency, 100% in the ideal machine, but 80% believe that, in practice, it is absolutely possible to get as. When using ammonia, can heat the ambient air, including mechanical work to convert, and this does not conflict with the second law, even if all scientists would say now - never a sweaty bodies and lenses in the tropics while Watts Experiments have forgotten, or at least overlooked.
You could do the advanced liquid and gas separate, then you could compresscool the liquid back into the original would be pushed to do very little to require zero if no change in volume occurs in the ideal case. This liquid could then absorb the heat from the cold source (fuel or environment) and again evaporated to gas, at constant temperature and pressure. The expanded gas is compressed in a normal game could be through the heat and this heat can be cooled to room temperature. With the liquid evaporates, the medium returns to the initial condition,ready to expand again in the next step.
Since the mass of the gas was less than the total mass of steam expanded first, the heat of compression is the same as the energy absorbed heat from the cold liquid. Ideally, the zero net work (= compression work is the extension of the work) and heat flows spontaneously from a colder (liquid) to a warmer (gas) region. But that is in the ideal case, which prohibits the second law. There are losses inpractical machine, which still represent a refrigerator operates at a much higher efficiency than present technology can achieve. Carnot rule can be broken, there is no physical law that is prohibited!
He may, however, show very difficult to separate the liquid and gas in the extended phase, particularly since it has to come spontaneously. It must be tried, and I have my ideas, as you know that the High yield and conversion, on the other hand, not whether this separationis needed, even has to be avoided, would be far easier to do and I do have a machine concept for it. All it takes, is a developer, who lets me work with it...
