Using the concept of bio-luminescence the "Glowing Plant Project" is working toward creating, literally, a natural light source. They are doing this by splicing the genes that control bio-luminescence in a bacteria into the DNA of a plant.
These plants, once they are perfected, could be used to light city streets and sidewalks. They can be used as decoration in your yard. They could be a nightlight for the kids. And all the while they use no electricity and act as a carbon sink.
Light is the thing that we, as modern humans, seek as much as food. But light uses a huge amount of power and, very often, is wasted (i.e. city lights on empty roads). Creating a passive, biological system that provides light for any number of situations is an idea that can radically change the way we deal with the dark.
