Inhabitat's Week in Green of November

We should admit that street lights are an important part of our life. They light our way home to safe at night but spent lots of electricity power in the whole night at the same time. So if we can create a kind of trees can light like Avatar could be multipurpose.

A group of scientists who may be the big fans of Avatar 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. What’s more, we can save the power of street light, create romantic atmosphere in park and reduce the probability of crime and risk, just really looks like playing the roles in Avatar.
