The streetlights on my street serve an excellent purpose, namely so that pedestrians can see what they are doing at night. It's just too bad they are so gawd-awe-fully ugly. The moon is much nicer, but cannot always be relied upon as the sole source of light when it's dark. So, how about designing some nice looking solution to the dimly lit night skies. Take this example and run with it. Looks good to my eyes, if I do say so myself. The fact that they are powered by solar energy captured when the sun is out and doin' its thing makes them all the better.
