Gold Nanoparticles Could Transform Trees Into Street Lights | Inhabitat - Green Design Will Save the World
Thats just plain awesome. I wonder what else we can do to make our cities resemble fictional places such as Rivendel
article said: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.
...trees, which I've always believed requires darkness to grow...
Found another republican.
:muffled laughter:
How would replacing glowing light bulbs with glowing leaves reduce light pollution?
Also, I wonder how the trees, which I've always believed requires darkness to grow, would feel about their leaves being permanently glowy.
Yes, whether I'm a Republican or not is directly associated with me hearing that trees need darkness. :roll:

The photosynthetic process occurs most readily when the sunlight available to the plant is the greatest. This is why plants in the tropics grow so large. They are near the equator where the sunlight is directly overhead much of the year. However, photosynthesis can occur in the dark. It does not occur as rapidly as during the daylight, but it is possible. If this were not the case, plants would shut down entirely every night when the sun went down.
It would increase light pollution when compared to well designed street lights.How would replacing glowing light bulbs with glowing leaves reduce light pollution?
It still requires energy input. Is the sun be able to produce enough of these wavelengths, and is the reaction slow enough for the light to last through the night without a bunch of extra energy input? Even if the tree lights are as energy efficient as LEDs won't much of the light be spent illuminating the tree?Article said:Under a high wavelength of ultraviolet light, the gold nanoparticles were able to produce a blue-violet fluorescence to trigger a red emission in the surrounding chlorophyll. [emphasis mine]
High gosh-wow factor, but a little thought reveals that it is probably completely impractical.
