Not at all. You are apparently assuming the full cm^2 of the chip is being irradiated. I am assuming, in contrast, but taken from a previous diagram of a Mills' experiment, that a pinhole detector was used. Big difference - as a sub mm aperture is irradiating the much larger detector chip - thus the low microwatt figure. Note: to protect these kinds of detector chips in a plasma reactor, a pinhole is customarily used. CAVEAT: I do NOT know that to be the case for certain here, but the only experiments (which I remember seeing) were set up exactly this way - with a pinhole and photocell. This point begs to be clarified, of course, since with a pinhole - the actual radiation flux at the spherical radius of the aperture, can a multiple of 10^5 or up from the actual area of the intercepted radiation through the hole. IOW - if it was not a pinhole detector then nothing that Mills has written, in terms of his past COP claims, makes much sense - Nor does my crude analysis of it. More later, Jones
