Revolutionizing Solar Energy by Taking It Underground
Here's how it works. Light is absorbed at the tip of the wire, and zips down its length and back, letting the zinc oxide convert it into electricity along the way. How effective is this process? Dr. Zhong Wang, who led the team of researchers at the Georgia Institute of Technology, says the wires only convert about 3.3-percent of the light that passes through. He hopes, though, that the number will soon jump to 8-percent.
That level of efficiency doesn't make it practical to wire your whole house with fiber-optics, but it's encouraging that researchers are trying different methods. As long as it doesn't lead to more stuff like this, we're fine with it. [From: ABC Science, via: Treehugger]
