Having realised that the moon reflects light from the sun a student wondered if this energy could be used so that we  could utilise the power of the sun at night.

What is the intensity of the radiation reflected by a full moon at the earth.

power from the sun = 3.8 x 10²⁶ W

average Moon Sun distance = 6.4 x 10¹¹ m

radius of moon = 1.7 x 10⁶ m

albedo of moon = 0.12

average moon earth distance = 3.9 x 10⁸ m
