Solar energy that doesn’t block the view
A team of researchers at Michigan State University has developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a clear surface. And, according to Richard Lunt of MSU’s College of Engineering, the key word is “transparent.”
"Visual microphone" can decode words from the vibrations in an object.
A MIT student has shown how the tiny vibrations caused by sound waves can be picked up by a high speed video camera, and decoded with software to figure out what sounds were being made.
The technique allows the researchers find out the subject of a conversation, for example, by watching the vibrations in a glass of water or a bag of chips.
