Gold nanoparticles could transform street-lights

Researchers in Taiwan have come up with the most perfect way of replacing your bog standard, ugly, inelegant and energy guzzling street lights. All of this shall be done by implanting their leaves with nano-particles of gold. This shall cause the leaves to give off a soft red glow which shall light the street for passersby below, without the need for electric power.
Not only would this cut down on carbon emissions, cut electricity costs and reduce light pollution, all this without in any way harming people by sacrificing the safety that street lights bring.

Like pretty much every great discovery before it, this one came about by accident, when aforementioned researchers were trying to lighting as efficient as LE D's without using the overly expensive and toxic phosphor powder that LE D's rely on. The gold nano-particles are shaped like sea urchins and are places into the leaves of Bacopa Caroliniana plants (that's the stuff you find aquariums) which causes the chlorophyll to produce a reddish luminescence.
This luminescence will cause the leaves' chloroplasts to photosynthesize, this as you will recall from your high school science classes will result in more carbon being captured from the air while the streets are lit. Their next step is to improve the efficiency of the bioluminescence and apply the technology to other bio molecules.

I for one, cannot wait.
