Greetings EEVBees:
--I concur with AntiProtonBoy. I would welcome any hard data on the IR film. A switchable, frequency selectable electronic mirror, indeed does not sound completely impossible. The way the guy was going on about everything being free, was confusing me though. I think he must have meant that no additional power source, other than sunlight or waste heat would be needed, and not that there would be no costs associated with manufacture and installation. And the Light Emitter, would it produce more waste heat that could be turned into light? If so, it might need a negative feedback circuit to prevent a runaway perpetual motion reaction.
--Also I am not sure, how tight a grip the gentleman had on the Laws of Thermodynamics. You know, heat flow, from a warmer reservoir to a cooler one, entropy, Maxwell's demon, that sort of thing. You cannot violate those principles long enough or often enough, even at the quantum level, to make a profit. A Light Emitter powered by nothing but waste heat, is just another version of the heat engine. I would be very happy, if my worries turned out to be groundless, but it did sound an awful lot like a magic anything box. "We can make anything we want out of water" Huh. Oh well, maybe I misunderstood his point. but, I am going to find it very hard to forgive the man for dragging dying children into the argument. He is fighting for the lives of dying children, while the rest of us are just pud knocker, I guess. That is not exactly what I call reasoned discourse. If this guy ever lands he should be fairly easy to swat.
