> and they're proposing 4.1-meter-diameter 3.6-gram probes, If you put 100 gigawatts on a 4.1 meter diameter very thin reflector, you're going to melt it. That's 10 gigawatts/square meter. Most of the light misses the targets. > i don't see where they're proposing how they propose to beam 100 gigawatts onto the probes so i don't know if this is their proposal A phased array on Earth, several kilometers in scale. > but nobody knows how to make one out of satellites yet Probably no one ever will make a huge (solar system scale) coherent power transmission system out of satellites, because of the thinned array curse-- https://en.wikipedia.org/wiki/Thinned-array_curse https://en.wikipedia.org/wiki/Thinned-array_curse It would be cool if we made a very large scale telescope, where a sparse array is less of a problem.
