This information, which I retrieved from several official sites, like Caltech, showed the evolution of the technology developed since 1998. The project started with 10W IR laser, ending with 47W lasers. The beam power amplification in the Fabry-Perot cavity started with a factor of 300, 20 years ago. This allowed them to publish that the "virtual length" of the largest arm was about 1,000 Km. As time advanced, the technology developed for the Fabry-Perot cavities (2 per arm) also advanced, reaching today an amplification factor of about 18,000 (what is equivalent to the mentioned 750,000 Watts). Again, don't blame me for the published data. I just quoted it, and also provided two links with valuable information. The oldest one points to an old document signed by more than 30 scientists (50 pages), which reveal the state of LIGO circa year 2000. And about the multilayered coating used in the mirrors, which also evolve with the pace of time, can be perfectly applied to the interior of the cavity that I proposed, without restrictions except money. I proposed a 550 nm green laser, without knowing the use of IR in LIGO. But, such wavelength makes possible multiple layers of coating (verifying thickness of integer wavelengths) and, also, a very low weight. I thought of 2 grams per cavity just because, but there are no differences in the outcome if each cavity weight 10 grams (this is a lot). The differential electromagnetic balance still will resolve nanograms. And regarding the absorbed heat of the entire cavity PER HOUR, I checked my numbers many times a while ago, and the numbers are ridiculously low. Consider that there is a direct relationship between Joules and calories, and that 1 CALORIE is defined as the heat that rises 1"C one gram of water. You can relate, then, the temperature increase per hour due to the absorption of energy of the 550 nm laser by the entire cavity. If you don't like that way of calculation, you can use the number of hits/second on every spot (area = that of the laser beam), and use this number multiplied by the number of spots in the inner part of the cavity. I clearly stated that the inner cavity has to have an irregular surface (in the order of nm) to guarantee that the beam is dispersed into the cavity, instead of hitting the same spot continuously. In the long term, the cavity will be filled with uniform green radiation, which is like what happened with Planck's black body cavity, that allowed him to develop his famous formula. There is much more to say, but this is not the place, so I stop here. Ideas are ideas, in particular if some realistic criteria are presented. Not the case of Einstein, his magic train, ghosts observers, perfect mirrors and beams of light in a fantastic world without gravity, matter and absence of forces that prevent inertial motion.
