New Metamaterial Means More Efficient Solar Cells
ElectricSteve writes "Metamaterials are man-made substances designed to do some very weird things that natural materials don't. The path of a beam of light through a natural material like glass is predictable, but scientists from the California Institute of Technology have engineered an optical material that bends light in the wrong direction. This new negative-index metamaterial (NIM) could have several valuable uses including invisibility cloaking, superlensing (imaging nano-scale objects using visible light), and improved light collection in solar cells."
This is not news. The cloaking technology was already used by the well known alien called Predator, which visited Earth in 1987 for the first time.
Even so, the technology proved to be rather inefficient on the battle field, hence Arnold Schwarzenegger's victory. Also, it's a well known fact that this victory brought him the governor title.
