Streetlights are an essential part of any urban landscape, but what if we could replace all of those power hogging lamps with trees that give off a warm red glow?
Dr Yen-Hsun Su from Taiwan's National Cheng Kung University discovered that when you add gold nanoparticles to the leaves of Bacopa caroliniana, it induces a red emission in the chlorophyll. Bacopa caroliniana is a plant widely found in the Southern US, but the same reaction might be possible in other plants and trees. Dr Ye-Hsun points out that this is potentially a win-win-win situation, with the glowing plants reducing power usage, and lowering light pollution, while absorbing CO2.
I just wonder how everything will look under a weird red glow.
