I told you. Read up about conservation of etendue. https://en.wikipedia.org/wiki/Etendue Your idea DOESN'T WORK.

This etendue thigamajig concerns brightness-area, and its conservation, related to conservation of energy. It says nothing about temperature or entropy, the content of the lens paradox. If you weren't so lazy, you might READ the note to which you respond, and read your own references. I'll spell it out. In a spontaneous thermal system, entropy increases. Intuitively, one expects that as a light wave spreads and thins, its temperature should decrease, and entropy increase. However, a convex lens concentrates the energy at its focal point, temperature INCREASES relative to the aperture; apparently anti-entropic. The second law is overturned! The explanation is Thermodynamics 101: that law applies to a CLOSED SYSTEM. But a lens transports energy through both ends. To close the system, we need to start at the original patch of sun surface, through space, through the lens, diverging out the other side. Finally, capture the light, feed it back to the source, see if it raises the temperature. Unlikely. The purpose of all such paradoxes is to test the student. You flunked. -- Rich

The entendu of a light beam is what accelerator physicists call emittance, considering the light beam as a bundle of light rays. There are theorems about its conservation, and linear elements, such as lenses, cannot change it. In particular, the entendu of the image of a lens is equal to the entendu of the light source, considering only light from the source that reaches the image. This is NOT conservation of energy, though it ought to be obvious that if a light beam is propagated without loss, the energy of the beam is constant all along its path; ditto for a particle beam. For a light beam, entendu is proportional to entropy; for a particle beam, emittance is proportional to entropy. > It says nothing about temperature or entropy, the content of the lens > paradox. It says nothing about temperature, but entendu is directly related to the entropy of the light beam. Note also that temperature is a property of an EQUILIBRIUM system. A light beam is nowhere close to an equilibrium system, and temperature does not apply to it. BUT: for the case of a hot light source emitting thermal radiation, and a lens focusing that into an image and heating an object on which the image is projected, one can discuss the temperature of the source and the object -- the latter can never exceed the former. Hint: if the object was hotter than the source, the thermal radiation emitted by the object would propagate in the reverse direction and heat the source. > [... lots of misunderstandings and confusions about entropy and > temperature] Tom Roberts

There are optical limits on how sharply such a source can be focused, and if you had bothered to actually work this out, you would find that the focused image cannot heat any object above the temperature of the source.

One would expect that, in an expanding EM wave, the entropy would naturally increase; think of an expanding gas. So this is a surprising result. I suspect it's somehow related to information conservation. Statistical mechanics is often modeled using an informational approach. Assuming the Maxwell equations govern the wave, it's deterministic in both time directions. Given the state at any instant, the entire history is fixed. Hence information is conserved. If entropy is conserved, there must be some deeper connection. -- Rich

Refuting a proposition in science has nothing to do with the technological task of building a machine. The refutation can be valid while the respective technology can be impossible, for many reasons.

In an electric field, the pressure in the bulk of water increases (becomes greater than the pressure in field-free regions): Tai Chow, Introduction to Electromagnetic Theory: A Modern Perspective, p. 267: "The strictly electric forces between charges on the conductors are not influenced by the presence of the dielectric medium. The medium is polarized, however, and the interaction of the electric field with the polarized medium results in an INCREASED FLUID PRESSURE ON THE CONDUCTORS that reduces the net forces acting on them." http://www.amazon.com/Introduction-To-Electromagnetic-Theory-Perspective/dp/0763738271 Wolfgang K. H. Panofsky, Melba Phillips, Classical Electricity and Magnetism, pp.115-116: "Thus the decrease in force that is experienced between two charges when they are immersed in a dielectric liquid can be understood only by considering the effect of the PRESSURE OF THE LIQUID ON THE CHARGES themselves." http://www.amazon.com/Classical-Electricity-Magnetism-Second-Physics/dp/0486439240?tag=viglink21401-20 "However, in experiments in which a capacitor is submerged in a dielectric liquid the force per unit area exerted by one plate on another is observed to decrease...This apparent paradox can be explained by taking into account the DIFFERENCE IN LIQUID PRESSURE in the field filled space between the plates and the field free region outside the capacitor." http://farside.ph.utexas.edu/teaching/jk1/lectures/node46.html This additional (non-conservative) pressure can produce cyclical flows that can be harnessed to do work. If, for instance, a small hole is punched in one of the plates of the submerged capacitor, the high interplate pressure will push water through the hole and so a permanent flow will form. Water in an electric field automatically becomes a perpetual-motion machine of the second kind. Vigorous motion is generated that can do work (e.g. by rotating waterwheels) at the expense of ambient heat (there is no other source of usable energy): https://www.youtube.com/watch?v=17UD1goTFhQ&t=1s Here a liquid in an electric field forms a jet: Fundamentals of the Electrospray Process https://www.youtube.com/watch?v=jqemod9DutI&t=4s The jet and other dynamic processes are powered by (A) electric energy? (B) ambient heat? It is not difficult to see that (B) is the correct (only possible) answer. More here: https://twitter.com/pentcho_valev Pentcho Valev
