One of my biggest pet peeves answered!
And take a look at this streetscene:
How is this possible ? It can be done using Lunar-Resonant Streetlights, the design of a San Francisco-based design collective called Civil Twilight who have won the grand prize from Metropolis Magazine competition for emerging designers.
The Lunar-Resonant Streetlights can "sense and respond to ambient moonlight, dimming and brightening each month as the moon cycles through its phases." The bulbs used in the lights would also be replaced and instead it would use LEDs and photosensors which dynamically determine the current ambient light levels and vary its illumation accordingly. One of my personal peeves is that of light pollution as I can no longer enjoy the night's sky in its full glory. This solution reduces light pollution by working with the current moonlight rather than trying to overpower it. The possibilities are wonderful as this product is an outstanding high-tech design which can easily help in bringing back the stars to a urban neighbour skyspace near you.
Mega hat tip to the WorldChanging article about these streetlights.
