This is from a few months ago, but it’s still interesting considering that it’s just what we need; more electromagnetic waves washing through our bodies. Feel the glow…
Imagine a future in which wireless power transfer is feasible: cell phones, household robots, mp3 players, laptop computers and other portable electronics capable of charging themselves without ever being plugged in, freeing us from that final, ubiquitous power wire. Some of these devices might not even need their bulky batteries to operate.

Realizing their recent theoretical prediction, they were able to light a 60W light bulb from a power source seven feet (more than two meters) away; there was no physical connection between the source and the appliance. The MIT team refers to its concept as “WiTricity” (as in wireless electricity).
[…]
WiTricity is based on using coupled resonant objects.
What about all the danger’s that we here about with power line emissions? Is this a healthy thing? Is their going to be any problems with interference from wireless power with other wireless products?
I do not find any information about these questions. I have yet to find a wireless product that I have not had some problems with at least intermittently.
Wow, what a terrible article. I read the entire thing and no mention of Tesla on their site. They have say the following
WiTricity is rooted in such well-known laws of physics that it makes one wonder why no one thought of it before.
Really? No one thought of this before? Not only does this sound like Tesla’s idea, it looks exactly like it. Both use two coils creating electromagnets and use tuned resonance.
They don’t provide a whole lot of detail about this project so maybe they stumbled onto something new to make this actually work but they could have at least gave Tesla a “shout out”.
I thought Tesla did have a working system. If I remember correctly, the reason why it’s not in place now, the power consumption can not be measured. So, the power companies couldn’t prove that you were using their electricity.
the main problem comes from RF…And what range you want to send and receive. Can you say, CELL, wireless, radios, maybe even SAt would be affected??
I’m working on a wireless extension cord.
A wireless power transmission system would be great places like a large farm or ranch (take a back road around Fresno some time, if you want to see how big a farm can be). An efficient power transmission system would mean lighter and less expensive tractors, trucks, etc. and I’m talking millions of dollars in equipment, fuel, and crop losses from soil being compacted. You bet the farmers would line up to buy into such a system.
The problem is getting the power to where it’s applied.
First, the inverse square law. This can be reduced by beaming the power, but that means weapons grade lasers, xrays, etc.
Second, “accidental receivers”, or power loss in wet ground and any bits of conductor that might be in the area (metal is worst, but anything that conducts is a problem). Made worse by exploding farm workers caught in the power beams mentioned above.
I haven’t read about this in about 40 yrs (Pop Mech covered it long ago), so there are probably other problems I cannot recall off hand. Lack of interested investors or market are NOT two of the problems.
Yeah, they should have mentioned Tesla.
Interesting..makes me resonate with #2 and the speculation that this group may have discovered some answers to the problems #6 mentions. Anything “in tune”
with a transformer’s coil is a potential conductor or I mis-remember the basics? Exploding farmers isn’t really funny to imagine so, I have to believe there’s either a tad more to the story or the folks involved with this project were once involved with the cold fusion project as well…
I saw this same demonstration about 5 years ago in Telluride and it was from 20 or 30 feet..I’m rolling out the BS meter on this one
Tesla was a bit of a fruit cake. I with Dvorak on this one.
Visual from the original Star Trek episode “The Ultimate Computer” where the M5 computer wirelessly connects to an alternate power source after Scotty tries to disconnect it. Redshirt in the way goes POOF!
Yeah, what could possibly go wrong?
“Turns on new wireless clothes dryer, head asplodes.”
John, I can’t believe that you’ve just commented above that this is “fishy”. There’s nothing fishy about it. A quick search via google will show that this concept has been proven numerous times. In fact, we have one common product which recharges using this “wireless” method. It’s the electric toothbrush.
