Two things I'd like to know: How detectable is "detectable"; what power level did the experiment yield? Microwave satellite transmissions have been "detectable" and very useful for decades. I don't hold it against them if they are 6 orders of magnitude lower than would be useful (yet), but I'd like to know they are getting in the are of transmitting power vs information. When this is scaled up, what is the energy density in the sky along the beam? Is it enough to have a detrimental effect on insects, birds, airplanes, etc., or can it be kept truly de minimus and still be useful? This is a key question related to considering whether we should just because we can.
