wireless electricity

A team of Massachusetts Institute of Technology researchers reported in Science Express, the online publication of the journal Science, that they had demonstrated wireless transmission of electric power by magnetically coupled resonators. They dubbed their technology "WiTricity" for wireless electricity.

While wireless transmission of electricity over radio waves is well known, it is very inefficient because most of the power is dissipated in directions other than the device that needs the power. Mr. Soljacic's team theorized that two copper coils tuned to resonate in identical magnetic fields would assure that the power was used only where it was needed.

amp'd flies for chapter 11

My comments: does not seem this means end of Amp’d, just that they are trying to reset valuation. Big losers are all the venture funds that put money in. As for Amp’d, assuming they can raise money again, valuation is poised to only go up (based on subscriber growth, it would be the time to invest).. e.g. Leap wireless post chapter 11


Amp'd Mobile Files For Chapter 11

Start-up wireless carrier Amp'd Mobile filed for Chapter 11 bankruptcy protection late Friday night, according to a person familiar with the situation.
The move marks the latest of several failed wireless ventures that focused on bringing video, music and other content to cellphones.
Bill Stone, president of Amp'd Mobile, confirmed that the company filed for bankruptcy protection.
Mr. Stone said the company was forced to make the move because its business has been growing fast in the past 6 to 8 months and couldn't keep up with the growth. "We are pretty confident we'll come out stronger," Mr. Stone said in an interview.
Amp'd Mobile has close to 200,000 subscribers and has advertised its brand name heavily. The company has also developed original video content.
