> pointing multi-megawatt beam of energy at any point on the ground, with little to no countermeasures available. Can't you use a mirror to reflect a significant part of that energy back, wrecking the transmitter? If it is several mirrors focusing on the same point on earth (like a solar thermal power station), just jiggle the mirror on land to sweep the mirrors with a beam of energy.
