Given:

  • earth to moon: 238,900 miles
  • there are four lagrange points that provide constant sun exposure at predictable locations
  • l1 to earth/moon: 1 million miles
  • the sun primarily produces visible light (not microwaves or gamma...)
  • laser transmission is more efficient than microwave, except where earth's atmosphere interferes

Basic premise:

<Earth> <- <Earth-orbit satellite> <- <Earth's moon> <- <Earth-Sol Lagrange-point solar array>
  • <Earth> <- <Earth-orbit satellite>

Laser transmit antenna in space: 1 meter diameter per GW Receive: Several hundred meters across

  • <Earth-orbit satellite> <- <Earth's moon>
  • <Earth's moon> <- <Earth-Sol Lagrange-point solar array>
