Given:
- earth to moon: 238,900 miles
- 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>
