A new product to keep windshields clean and dry, recently available in the US, employs nanotechnologies (i.e., really freaking small technolgies) in its formula. The product, Nanoprotect Automotive Glass, which repells water and keeps dirt from collecting on windshields and windows, is a svelte 20 nm, which is 500 and 25,000 times thinner than silicon-based substances. Don't ask us, we still wash our windows with newspaper.
