Birds, bats, insects, planes in the path of the bean will be fried and what is the dispersion on that beam - how much of the country side will be uninhabitable?
Birds crash into clear windows and windmills, and also down planes. Bats get poisoned by insecticide. Planes, as I’ve already answered, can be advised of restricted areas, as they are right now of military restricted areas. As for the “dispersion of the ‘bean,’” send it directly to one or a few high-altitude reception point, and distribute it from there.
Right now, the big cities are becoming uninhabitable. Should we ban guns? There are viruses that can become a pandemic. Should we all wear masks and hide in our houses? Everything has risks. Intelligent planning and a modicum of courage and forward thinking can minimize those risks.
