> Desert sand grains are too smooth to be useful I wonder how hard it would be to convert smooth sand into angular sand. Perhaps a pulsed laser could be used to fracture the grains into angular fragments or something like that. Not only would being able to use desert sand create an abundant supply, but it'd be beneficial for fighting desertification.
