Another "thought experiment" . Here is a video an oscillating mirror which "creates photons". and this has actually been proved in experiments at low power. Moving the mirror requires energy input which makes the "free photon" production less than overunity, of course... at least for now. The mirror in this case is a planar metallic surface fabricated at nano-geometry using the same lithography techniques of the semiconductor industry.
http://www.youtube.com/watch?v=eDzqqsTFywk The goal of this thought experiment is "persistent light," not to be confused with the biological term. This is a form of overunity, and thus is technically impossible without an outside source of energy, which is to be the DCE, or dynamical Casimir effect. If DCE moves the mirror then net gain will be possible in the form of persistent light and a photon chain reaction. Now, Imagine a hollow sphere as a mirror. Obviously light can be reflected by a sphere, both internally and externally. If the sphere wall is thin enough, the sphere will naturally pulsate at the blackbody rate. If the pulsation is in step with a multiple of the wave length of light being reflected, and have "created" photons in the hollow sphere, then "on paper" at least, DCE would be the proximate source of gain for persistent light. With phonons and photons resonantly vibrating - if the spheres are translucent - we have a material which "glows" and tends to lock adjoining spheres into harmony. The phonon pulsation would be at an IR frequency and the photons would be visible and either coherent of superradiant. The ratio of the two wavelengths cannot be too great, or any kind of resonant coupling would be lost. An interesting starting point is to start with photon input from a low-pressure sodium lamp, which naturally gives only monochromatic yellow light at 589 nm. Once near coherence is reached the lamp is shut off. If the "glowing" material is a dielectric, like titania, we have what is known as a "dielectric mirror" (aka Bragg reflector). In short, this experiment proposes that a "photonic chain reaction" (defined as extreme persistent luminescence) follows from a variation of the Bragg reflector, made of translucent titania nanospheres, which are commercially available and will benefit from added "created photons" from the internal vibrating mirrors. Losses can be extremely low, since 99.99% of incident light is reflected, so the DCE photon creation only needs to make up a few ppm of losses. The trick is to tailor everything together at stepped resonance. The most extreme ratio where coupling occurs is not known, but probably would benefit from a third medium in the middle, since IR wavelengths are so much longer than visible light. IR Triple coherency could be possible in this context, if a another reflective and electrically conductive material were interspersed with the titania. This could result in mutual resonance for photons, phonons and electrons (the matter wave of the electron if the conductor was an exciton). Here is a step one: start with "photospheres" of a chosen cavity size (to match an IR wavelength) which have cavities in the Casimir range of geometry. http://www.cospheric.com/TiO2_titanium_dioxide_coated_glass_spheres.htm which are rather pricey, so this proposal will await a sponsor to move into the Lab, but as they say in the MasterCard ads, the result could be priceless. At one time, it looked like a AC frequency could work as the 3rd system to be made coherent, but "static" charge is a better bet- in the sense of a local field. Thus, the next step is to mix excitons into the titania in the form of QSI nanospheres. An IR photon with a wavelength of 9.4 microns is a ratio of 16x the monochromatic emission of sodium and has an energy of less than .2 eV. That IR photon would be paired with an electron with a kinetic energy of .0002 eV. The associated DeBroglie wavelength is about the same as the photon, but that is rather "cold". In effect this is a static free electron with an oscillating exciton hole, and that the entire structure with intermixed titania is semi-coherent and translucent. "Persistent light" or the "photon chain reaction" would be a form of overunity which has enormous appeal, since it is self-powered in a most obvious way that cannot be denied - and can in principle be powered by DCE. The devil is in the details, however, and as you can see, I am not there yet on getting the details to line up for triple coherency. This is an invitation for anyone who has been thinking along these lines to propose their own version of persistent light, even if it requires LENR instead of DCE. The holy grail is a stand-alone system with no outside power input after startup, such as Dennis Cravens "almost" demonstrated at NI Week. So close but so far away. "Self-power" in one form or another is where the skeptics will have to put-up or shut-up, as they say.
