Dust ballistically shot from the moon can reflect sunlight

Researchers in physics and astronomy at the University of Utah have concluded that we could end earth's energy imbalance by repeatedly shooting dust from the moon into space toward the sun.  Dust placed at the L1 Lagrange point is rapidly blown away by solar wind and radiation forces as shown in the image above and the dust needs to be constantly replaced. They conclude that, because the dust will be blown away, it would be most effective to simply launch dust from the moon toward the sun without enough velocity to reach the L1 point.
