Well, we found an innovative address marker that also happens to be green. Maybe this will start a new obsessive trend..
matterinc's aluminum frame is cut into a stencil so that numbers show up via the backdrop of your home's wall. Solar panels atop the frame absorb the sun's energy during the day in order to power two backlight LEDs at night.
It only takes about an hour on sunny days and two to three on cloudy days to fully charge the unit.
The numbers come in anodized silver or black.
While we like the nighttime effect, the solar panels are a bit overbearing. We wonder if there's a way to minimize them. Couldn't you use smaller panels that take more time to charge?
Have you seen any other cool green house numbers out there?
