Here is the "single simple law of experience" he proposes:<br /><br />"It is impossible to construct an engine which will work in a complete cycle, and produce no effect except the raising of a weight and the cooling of a heat-reservoir."<br /><br />This "law of experience" is very similar to a principle suggested by William Thomson (Lord Kelvin):<br /><br />"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."<br /><br />The "simple law of experience" offered by Planck is therefore commonly known as the "Kelvin-Planck statement" of the Second Law of Thermodynamics. But we see from Planck's "Treatise" that Planck himself did not quite regard it as a statement of the Second Law, but rather as a "starting point" or postulate from which the Second Law may be deduced.<br /><br />Here is Planck's rendition of the Second Law itself:<br /><br />"The second law of thermodynamics states that there exists in nature for each system of bodies a quantity, which by all changes of the system either remains constant (in reversible processes) or increases in value (in irreversible processes). This quantity is called, following Clausius, the entropy of the system."Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8861605.post-40674638902163032402013-12-14T22:16:58.671-05:002013-12-14T22:16:58.671-05:00The Kelvin-Planck formulation of the Second Law of...The Kelvin-Planck formulation of the Second Law of Thermodynamics may be stated as follows:<br /><br />"No cyclic process driven simply by heat can accomplish the absorption of the heat from a reservoir and the conversion of such heat into work - without any other result (such as a transfer of heat to a cooler reservoir)."<br /><br />Now, as you will see, the Clausius formulation of the Second Law may be stated with fewer words:<br /><br />"No process is possible whose sole result is the transfer of heat from a cooler to a hotter body."<br /><br />In fact, we can show that the Kelvin-Planck formulation may be deduced from that of Clausius. In the words of Enrico Fermi:<br /><br />"Suppose that Kelvin's postulate were not valid. Then we could perform a transformation whose only final result would be to transform completely into work a definite amount of heat taken from a single source at the temperature t1. By means of friction we could then transform this work into heat again and with this heat raise the temperature of a given body, regardless of what its initial temperature, t2, may have been. In particular, we could take t2 to be higher than t1. Thus, the only final result of this process would be the transfer of heat from one body (the source at temperature t1) to another body at a higher temperature, t2. This would be a violation of the Clausius postulate."<br /><br />Can anyone make a teapot that boils water by absorbing heat from blocks of ice?

Such a machine is called a "perpetual motion machine of the second kind". The second law declared the impossibility of such machines."<br /><br />"A perpetual motion machine of the second kind is a machine which spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy. However it does violate the more subtle second law of thermodynamics (see also entropy). The signature of a perpetual motion machine of the second kind is that there is only one heat reservoir involved... This conversion of heat into useful work, without any side effect, is impossible, according to the second law of thermodynamics."<br /><br />Goldes' make-believe strictly ambient heat engine would be a perpetual motion machine of the second kind, as defined above. Goldes is not developing any such engine; he is merely developing a pretense - as usual.

There is only pseudoscience and pretense - and nothing new, at all.

The brilliant idea of this revolutionary breakthrough is to blow a horn at a magnetized tuning rod, designed to resonate at the frequency of the horn, and then collect the electromotive energy produced by the vibrations of the rod.<br /><br />We're not making this up.<br /><br />POWERGENIE tuning rod engine explained - from the patent:<br /><br />[The device incorporates] "an energy transfer and multiplier element being constructed of a ferromagnetic substance... having a natural resonance, due to a physical structure whose dimensions are directly proportional to the wavelength of the resonance frequency...<br /><br />"In this resonant condition, the rod material functions as a tuned waveguide, or longitudinal resonator, for acoustic energy...<br /><br />"Ferrite rod 800 is driven to acoustic resonance at the second harmonic of its fundamental resonant frequency by acoustic horn 811..."<br /><br />- But the patent doesn't tell us who will volunteer to blow the horn at the rod all day. Perhaps it will come with an elephant.<br /><br />Mark Goldes claimed in 2008 that this wonderful triumph of human genius would bring his company, Magnetic Power Inc, one billion dollars in annual revenue by 2012. Magnetic Power is now defunct, having never produced any "Magnetic Power Modules" - just as Goldes' company called "Room Temperature Superconductors Inc" is also now defunct, having never produced any "room temperature superconductors."

This has been understood by physicists for at least 180 years. There is no "new science" that has ever determined such an engine to be possible.<br /><br />Aesop Institute's make-believe "Virtual Photon Flux" engine is based on the idea that accessible electric power "is everywhere present in unlimited quantities" - which we know to be false.<br /><br />Aesop Institute's make-believe "Collapsing Hydrogen Orbital" engine is based on Randell Mills' theory of "hydrino" hydrogen, which every scientist knows to be false.<br /><br />Aesop Institute's make-believe horn-powered engine is based on the pretense that a magnetized tuning rod could somehow "multiply energy" - a ludicrous notion, which is obviously ruled out by the law of conservation of energy.<br /><br />Aesop Institute's very latest make-believe engine is a perpetual motion machine in the form of a self-powered air compressor, which uses a turbine to compress air to spin the turbine to compress air to spin the turbine. <br /><br />Aesop Institute has never offered the slightest shadow of evidence that it is actually developing or "prototyping" any of these make-believe physics-defying "revolutionary breakthroughs."

This is clearly indicated even in the article by Kondrashov posted by Goldes on his flimflam website. Kondrashov says:<br /><br />"To create a sample of such an engine, you can use ready-made devices, such as a load-bearing element - a low-power turbine module turboshaft turbine engine, and to compress the air... any type of compressor..."<br /><br />Kondrashov filed his patent application in 2003. No patent was awarded.<br /><br />Mark Goldes assures us in his note prefacing Kondrashov's article that "We understand the science behind this jet engine." But since he incorrectly describes it as an engine powered by "atmospheric pressure" - which it certainly is not - in fact he shows that he doesn't even understand that the engine requires a supply of compressed air in order to spin at all.<br /><br />Although Kondrashov does pretend in some of his statements that the turbine will be powered by "atmospheric pressure," in fact it is evident from his application that the proposed turbine is made to spin only by the use of compressed air. <br /><br />In his patent application, Kondrashov states: <br /><br />"To set the above engine in operation, it is necessary to create pressure of working medium (e.g. air) in pneumatic accumulator 18. The compressed air is fed through check valve 19 and/or 20."<br /><br />Thus, Kondrashov indicates that an external compressor must be used to fill the turbine's compressed air tank before the turbine can be started. But he seems to expect that once the turbine starts to spin, there will be no further reliance on the external compressor - the spinning turbine itself will compress the air that is making the turbine spin. So despite his own false description of the turbine as making use of "low-grade atmospheric energy," what Kondrashov actually presents in his patent application is a perpetual motion machine in the form of a self-powered air compressor. This is probably the reason why no patent was awarded. It is exactly analogous to trying to use a generator to power a motor to spin the generator to power the motor to spin the generator. It doesn't work.

I am generally pessimistic that they will happen in a timely manner to allow a dignified descent, but I have made peace with that.<br />I sometimes think of pre industrial Japan as an example of a sustainable civilised society. There most definitely were cycles, but overall they managed a relatively high population density, without degrading their habitat. For a thousand years or so.<br />Their agriculture was obviously organic, but not as we know it. Modern organics still use the same amounts of fertilisers, the only difference is the nitrogen comes from fish or seaweed, not natural gas or lignite. The same for other nutrients, the phosphate is rock, or guano etc.<br />The Japanese and many other cultures had various methods of composting, or directly applying 'night soil'. Which means a nearly closed nutrient cycle, with the exception of bodies. <br />I have seen some signs of this in my own town where the council has just introduced a system where a tiny fraction of liquid sewerage is being applied to pasture, to be made into hay. It stinks like you wouldn't believe, but it's a start.<br /><br />Regards, AndyAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8861605.post-41529710425626622202013-12-01T15:14:42.452-05:002013-12-01T15:14:42.452-05:00I agree with anonymous that we need full cycle ana...I agree with anonymous that we need full cycle analysis, and that sharing cars fall short on this count. However, I think we should not dismiss incremental, interim approaches that reduce overall throughput. There is no way to convince human societies to go back to an agrarian or hunter/gatherer culture, not in the short run. While current human numbers MIGHT be supported with a wholesale change to organic agriculture (meaning a lot more people, maybe the majority are growing food), a hunter/gatherer culture would mean drastically fewer humans able to survive, especially in the degraded environment we now have.<br /><br />In rejecting incremental approaches, I think anonymous is, in effect, rejecting the most effective avenue we have for change. I know only too well that half measures will not suffice. But, when the choice is between half measures and nothing, we should not foolishly reject the half measures unless they prove to be more injurious than current practices. Hence, my emphasis on the sharing part of the equation here rather than the existing infrastructure which will be with us for some time no matter what we may wish.Kurt Cobbhttps://www.blogger.com/profile/05330759091950742285noreply@blogger.comtag:blogger.com,1999:blog-8861605.post-78298154739592123672013-12-01T14:46:01.200-05:002013-12-01T14:46:01.200-05:00Sustainability requires a full cycle, full system ...Sustainability requires a full cycle, full system analysis. I think sharing cars will fall rather short in this analysis because there is nothing sustainable about cars. There is probably nothing about modern life that could remotely be called sustainable. <br />Sustainable requires the total elimination of wastes. With regard to agriculture the biggest waste is the nutrients which are for all intents and purposes flushed out to sea. So it's no surprise we need to reapply more nutrients every season.<br /><br />The lack of full systems thinking is exactly why solutions are the biggest cause of problems, and why we are, where we are today.
