"Multiple Self-Sustaining" LED Streetlights

Things aren't always what they seem. But sometimes they are. This Prisma streetlamp not only uses High power LEDs to shower the streets with it's luminescence, but it's interactive and pays for itself to boot. It's supposed to be able to be controlled by a user, say for street fairs, which is pretty nifty, and even has solar panels(but then again what gadget nowadays DOESN'T have it) to help run the motor that turns the head assembly. Kind of defeats the purpose though if the main power for the light is still coming from the grid. The actual self-sustaining part is the fact that the vertical light can be pointed at various signs, banners, effigies of Jesus, or other advertising detritus to add an additional revenue stream to the mix. Not quite the supergreen product, but more like a light sea foam. Sadly (or perhaps happily), this is only a concept product, so you won't be hacking a Batman symbol on the top dome any time soon.
