Sun shields from Moon Dust

Curtis Struck of Iowa State University suggests that lunar dust particles are just the right size to scatter sunlight. They could be positioned in the Moon's orbit in a pair of stable clouds that would each pass in front of the Sun once a month, blocking sunlight for about 20 hours each month (Journal of the British Interplanetary Society, vol 60, p 1).
