MIT Team Powers Light Bulb Without Wires

CAMBRIDGE, Mass. -- In a perfect world, there'd be no wires. They clutter the view, get tangled behind desks and limit how far networks can reach. That's why the telegraph gave way to the radio. Cell phones unstrung telecommunications. Wi-Fi liberated computer data.

'Maybe a solution for alternative energy, or something' A group of MIT students and staff has used stationary cycles to power a computer, in a feat that was described by one of them as "something that will hopefully lead to maybe solutions for alternative energy, something like that".â¦

FOXBORO, Mass. -- In a fresh slant on the standard light-bulb joke, instead of asking how many Seahawks it takes to screw in a light bulb, one wonders how many light bulbs it takes before the Seahawks can screw one in without dropping it.

NANOTECHNOLOGY -- engineering substances down to billionths of a meter in size -- holds out such promise of providing super-strong materials or desalinating water inexpensively that no one wants to put a red light in its way. But there are enough safety questions to justify more yellow lights than either industry or government has yet deployed.
