Wireless electricity!
WOW! Check this out!
Intel cuts electric cords with wireless power system - Yahoo! News I know it's not technically video related but we use laptops to edit video....well a lot of us do anyways. Thought it was pretty interesting. |

Can't wait till people begin hacking wireless power sources. |
wireless power
wow sounds great but I still think it will be awhile before we see it in the common market place. Ya the possibility's are endless with it.

The technology (what little I can tell) looks old. I own devices that already use magnetic fields to recharge, and there is wireless interfaces that works this way, how safe they are, well. To a certain extent I think everything is magnetic, even if it is so small as not to overcome gravity and effect the weight of an object on a kitchen scale. But you still are going to be jostling something back and forwards. There are even better techniques that have come up in the labs in recent years. I find the statement about electric fields and magnetic fields (electricity forms electromagnetic fields) so I wonder if there is a deep trick to forming the magnetic fields. |
Didn't Tesla demonstrate the viability of wireless energy transfer like, 100 years ago only to be marginalized by individuals and corporations (Edison and Westinghouse, mainly) with a vested interest in running lines?

Radio-frequency transmissions, the television you enjoy, radio, cellphones etc., are wireless transmissions of energy which happen to have been deliberately modulated to convey an intelligent signal.
As a means of reticulating power, it is not so practical. For instance, how do you stop people from simply harvesting the available power without paying? |

In the Yahoo! article it says: "Electricity was sent wirelessly to a lamp on stage, lighting a 60 watt bulb that uses more power than a typical laptop computer." I'd like to know what kind of bulb. If it is a modern compact fluorescent then it has been done before. People have demonstrated that full size fluorescent tubes can operate without a wired connection. I'm also wary of articles that can't get the most trivial science correct: "It turns out the human body is not affected by magnetic fields; it is affected by elective fields." Elective? So it can vote? |

It's definitely been done before. It's not new technology. However, Intel seems to be able to get more efficiency out of the process. Yet, they are still losing 25% of the energy. It definitly looks like a short range system. |
Just a thought to ponder...
All AC powered devices (that use transformers) are effectively wireless. |
