"If you thought mousetraps were tough, try building a better lightbulb. Just in time for Earth Day, a team of American inventors have created a bizarre-looking new bulb that turns illumination on its ear, using light-emitting diodes (LEDs) clustered within a conventionally shaped bulb for illumination rather than filaments or fluorescent tubes. It will never end up in a landfill. It will not poison anybody. It may be the light of the future, hopes Switch Lighting CFO Brett Sharenow.
An electromagnetic "black holeMovie Camera" that sucks in surrounding light has been built for the first time.
The device, which works at microwave frequencies, may soon be extended to trap visible light, leading to an entirely new way of harvesting solar energy to generate electricity.
