3698. Beam Forming for Power and Propulsion
Solar power satellites have been proposed to supply energy for the Earth. The power would be beamed to Earth in the form of low-density microwaves or laser light. Another application of beamed energy may be interstellar lightsail propulsion . High velocities for the sail, up to a quarter that of light, require that the sail be kept as low in mass as possible. Sail masses of one kilogram and one gram are considered, having diameters of a few to about thousand meters. The challenges are considerable, but such missions may be doable, given sufficient research.
