Maybe nanobots can remove the dust :-) .
BTW: I've lived in the Sonoran Desert for many years. The undisturbed desert floor is covered in a patina (varnish) and there's almost no dust. It takes many decades for that to form. Driving vehicles on it ruins it and then there's lots of fine dust. If the builders had been careful, maybe they could have avoided disturbing that. Maybe there's an artificial way to put it back. You'd have to keep the "off roader's" at bay.

Dust is not transparent, so even just one gram of dust per square meter of solar panel area can reduce efficiency by <http://www.tandfonline.com/doi/abs/10.1080/14786450500291834#.UbIQLWRATzc> around 40 percent. At that rate, it doesn't take long in a dusty desert for the problem to become intractable.... --- This email is free from viruses and malware because avast!
