The following comments relate to this news article:
article published on 21 August, 2008
Back in 2006, Dr. Marin Soljacic at the MIT Department of Physics and Research Laboratory of Electronics demonstrated the transmission of Electricity using using magnetic resonance. On Thursday, Intel was to demonstrate some progress in the wireless charging technology, which could be used to charge laptops, MP3 players and mobile phones without the need to connect any wires.
Intel was ... [ read the full article ]

I had actually researched this technology once. I didn't know Intel had shown interest in it. I hope that is can become more effective in the near future and not require that mat. Like a global wireless electric flow that kept all devices charged at one time.

uhuh yeah, lets just send electric volts around the house. let alone what will happen if it shorts or overloads.

One day someone will walk out of the shower, they'll feel all warm and good.. but then pow electrocuted to death.. then they'll wonder why they even did anything like this... ahha. jokes aside if they can get it stable and working I wouldn't mind investing in some of this stuff :).

demonstrated the transmission of Electricity using using magnetic resonance....
i thought Nikola Tesla invented and demonstrated this back in the 1900's Nikola Tesla had multiple patents disclosing long distance power transmission
wireless telecommunications and electrical power distribution achieved through the use of earth-resonance principles.
its on wikipedia

But everyone knows transmissions over short distances is much more difficult. lol

21Q, you REALLY do not want that. Magnetic resonance is only reasonable at tiny distances. Otherwise the power requirement would be out of the question. The power drop over distance is a huge logarithmic factor. I knew someone that actually understood this problem and was discussing it with me 20 yrs ago or so. At 20 ft the full power of the Hover Damn couldn't supply enough power to charge an ipod. Anything that had ANY metal within 5 ft would be fried. Probably the hemoglobin in our blood would be affected if we walked into the kill zone. I am sure the term would be a literal one. Maybe it would rip the hemoglobin out of our bodies or something like that.
The dramatic power drop off actually makes the tiny distance transfer safe.

sending energy though the air is a interesting idea, its not real voltage persay but magnetized energy that can only really electrify its receiver.

it will take another 10+ years to have something that can charge a item only begin a few MM away.

Haha Mez that's actually a [retty interesting thought. Never thought of people getting killed from it, seeing as how we do conduct electricity. Would a magnetic field bear the same result as getting shocked though? And yeah the distance .. hmm. Well that is what future technology and advancement is for.

It is not elecricity but a kind of magnetice force that is powerful enough to move free electons in thing like copper wire. I am sure I don't understand the concepts other than AC current is created by just moving free electrons back and forth. AC current is generated by using magnets that move across copper wire. Motors do the reverse. Electons push the magnets.

A company in the UK called Splash Power has previewed this some time back on TV for items like mobile phones,Mp3 players etc...
Check this out http://www.splashpower.com/

And to think, I was worried about cancer after regular wifi transmissions and holding a cell phone next to my head.
This will last about as long as until someone gets the bright idea to sue them, saying is caused cancer.
It will freak some people out too much. There will be protests against "second-hand electricity"

...not to mention that such a large "transmission loss" would fuel a lot of protests from environmentalists and green energy folks.
This will take quite a bit of work.

You are absolutely correct. Tesla succesfully demonstrated the wireless transportation of electricity. I believe that this was a roughly 100 years ago or so.
My guess is that some corporation bought that patent and locked it away so that they could continue to charge the consumer for the corded service. How would one regulate wireless electricity?

The military cloaked a ship for a very brief moment many years ago with a very strong magnetic field however most of the people died shortly afterwards.
Will I need to buy a lead suite like what they give you for X-Ray's? LOL
I can?t believe they are wasting their time with this it will create more problems and waste more power then it is worth, how stupid!

Yeap, mutation but not that bad. I'll just put on my dark robes and shoot lightning out of my finger tips at people who displease me.
Come to the Dark Side we have wireless cell phone chargers,MWHAHAHAHAHA.

Tesla coils make artificial lightining and are often in the labs of mad scientists as seen on TV. In the US patents run out in 17 years but even if they lasted for a century that patent would have expired. I think the company holding on to the technology was afraid of law suits when the 100,000 volt lightining bolt missed the target device and kills the human. I guess the advantage would be if you didn't die in the charging process, you could charge your ipod in less than a second. I think I want one! You need high voltage to make electricity jump through air. The further away, the more volts you need.

No, it would work like Microwave does now. You know those scan-badges that people use at work? That's kind of how this will work. When the badge gets close enough to the plate, the microwaves from the plate carry electricity to the badge, which powers the microchip in it, which then emits a short code back to the plate which then interprets it and gives (or denies) access, based on programmed permissions.
In essence, you could have your video game system providing the wireless controllers with an infinite supply of power (never charging battery packs again!), or a cell phone you can charge just by setting it on your computer case...

Being a form of light, microwaves are not effected much by distance like magnetic forces and electicity. They can still boil water in your tissues if they are powerful enough. However, small charges are safe.
You proposal sounds 'real world' but possibly still hazzardous. Cell phones are now suspect for cancer and they transmit less juice than a power supply.

Sounds still too much like the realm of fiction to me. Or rather non-practicality. Hence why it stayed in fiction like G.I. Joe: The Movie. The Broadcast Energy Transmitter. 21 years ago and still just not practical.

over one hundred years of its discover and no advancement on it, truth be told i don't think it can be done. if it could the military would have tried this years ago. the reason i don't think it can be done is simple what is controlling the current to the device not a dame thing Electricity is dangerous no matter how low the volts, you have to play all the variables that modify electricity range and output the second it leaves the device
