One day when I was using my laptop here at school, I was thinking about the technology behind wireless internet, and how amazing it is that so much information can pass through the air. Even though the technology is relativity in-expensive and is available for consumers at a reasonable cost, it is truly amazing how we can light up our networks without even a wire. So this got me thinking, if we can rapidly download data through the air on our computers, phones, tv's, ect. What is stopping us from powering our electronics, and even our cities without wires? According to CNN, within a few years we may be able to charge phones, iPods and other electrics without using charges. Check out this article posted yesterday on CNN. http://www.cnn.com/2009/TECH/09/02/wireless.electricity/index.html?iref=newssearch
The first minute of this video basically shows an example of wirelessly powering devices. If you are interested, you can watch its entirety with specifics about how it works.
