We all know the cellphone masts disguised as trees, created in an attempt to blend technology within the ‘natural’ landscape. Now Taiwanese scientists have created trees that could function as streetlights. They infused the leaves of Bacopa Caroliniana with gold nanoparticles which causes the chlorophyll to produce a reddish luminescence. This phenomenon is awkwardly named bio-LED by the scientists.
According to Yen Hsun Su of the Academia Sinicia and the National Cheng Kun Univerisity: ‘The bio-LED could be used to make roadside trees luminescent at night. This will save energy and absorb CO2 as the bio-LED luminescence will cause the chloroplast to conduct photosynthesis,’ This means that while the tree is ‘lit’ more CO2 is consumed from the atmosphere, therefore the glowing trees could reduce carbon emission, cut electricity costs while still lighting streets safely.
