Great, hopefully a few years down the line we can lose that damn rats nest of power cables..

| 40% effeciency. Not a very "green" technology though. |

Pretty darned good for the first attempt though. Can't wait to see how this develops in the future.

| Didn't Tesla already show this could be done over 100 years ago? |

Werent they talking about microwave energy plants collecting enegery beemed tot he surface from a satelite generated by huge solar arrays like 35 to 40 years ago. I read books about it when i was a kid.
Plenty of risks with that though.

Lots of people have tried this and gotten varying results. I think this is the first really significant and useable showing of this technology ever. 40% efficiency for something like this is incredible and the fact that it is only going to improve from there is absolutely amazing.

The efficiency sucks for something continous as someone else said.
But on your note you have to think of other uses that are short term and temporary. |

Well yes it does suck, I will give you that. But you also have to remember that this is the first time it has been effectively tried. Think about in the past with the roots of electricity. What do you think the efficiency of wires was before the introduction of superconductors? While it wouldn't be nearly as low as 40%, it still sucked compared to what we are used to today. This is still a very new and developing technology and is only going to get better from here on out.
On another note here is some more information on wireless power transmission by Tesla. That man was beyond brilliant. Who knows what he could invent with the technology we have now.

we wouldn't have the technology now if he hadn't been back then:) |

Its always gonna be low and in fact 40% is brilliantly good for air transmission of a non microwave source.
But my real point is you need to think f uses for things that arent always on. SOmething that only needs to turn on when power is sent to it and then turns back off again. Theres a million uses for it.
Image remote controlled devices that dont require their own power. You push a button it turns on and off for whatever its purpose is and the only power is in the remote....
EVen on that note something that small would probly not be around soon but i figure u can think of larger uses. |

| Interesting... my guests already use my neighbor's wireless broadband and with this we could all enjoy their power. Now if I could get access to their fridge I'd be set. |

Well hell we figured out that one years ago. But do you know how high of a voltage it takes to shoot a bolt 15,000 feet or more?
Not exactly a practical application but its been used lol. |

But how do you aim something like that while being able to guarantee that it won't disintegrate whatever is in it's path?
