Gold Nanoparticles Could Transform Trees Into Street Lights | Inhabitat – Green Design Will Save the World
The idea of glowing trees seems kinda cool at first, but if the leaves are full of gold what will we do about leprechauns.
Street lights are an important part of our urban infrastructure — they light our way home and make the roads safe at night. But what if we could create natural street lights that don’t need electricity to power them? A group of scientists in Taiwan recently discovered that placing gold nanoparticles within the leaves of trees, causes them to give off a luminous reddish glow. The idea of using trees to replace street lights is an ingenious one – not only would it save on electricity costs and cut CO2 emissions, but it could also greatly reduce light pollution in major cities.
