Scientists Invent Wireless Electricity Beaming

www.dailymail.co.uk...

The end of the plug? Scientists invent wireless device that beams electricity through your home.

In a breakthrough that sounds like something out of Star Trek, they have discovered a way of 'beaming' power across a room into a light bulb, mobile phone or laptop computer without wires or cables.

In the first successful trial of its kind, the team was able to illuminate a 60-watt light bulb 7ft away.

Amazing stuff! What happens if a person or animal gets in the way of the power stream? ZAP?!

dang, beat me to the post! haha.

Tesla was right ;-)

they have had similuar tech out for a few years. A table like device that you set you electonics on, and it rechagnes it.

Didnt invent anything, that property was "discovered" 200 years ago.
Just a very strong transmitter.

Yeah, this is just grandstanding by the newspaper and the "inventors". Microwave power transmission's been since at least 1964.

Old technology. Tesla was experimenting with this concept like this in the early 1900's.

well, if we can do away with cables, then its a good thing, but what if you leave the iron on and go on hiliday for a month? Have they got something to switch the current off?

If it was invented soooo long ago, what were they waiting for? cables?

I think it's a bit more than a very strong transmitter.

First, it seems to be some sort of near-field H-field trick from what's left of the details after the journalists got hold of it. But it's not just that, because coupled coils lose energy as the sixth power of the distance (much worse than radio with distance squared).

The demo supposedly was 40% efficient from 7 feet away. So it's not radio, and it's not coupled magnetic fields. Someone emailed me the paper but I haven't had a chance to look at it. I'll post it when I get a few minutes free to read it.

wtf scientist invent it now, tesla had the idea, and i think he already invented it back in the day, wow i guess science is Charlie foxtrait

Bad title, incorrect factually and historically, as many have pointed out.
A simple modern example of Magnetic Induction as demonstrated by Tesla is with a Plama Ball and a Florenscent bulb
the mercury vapor is excited due to magentic induction and this is a wireless demos you can do yourself.
Bet your friends you can light the bulb, no powersource, I have made good money on this



Simple basic physics, certainly not invented recently

The pulsating field around the glass sphere is strong enough to excite the mercury gas inside the fluorescent bulb, which in turn excites the fluorescent coating on the inside of the glass spiral and makes it glow.

Not knowing much about the science behind it, I do have questions.

How is the amount of power transmitted to or received by devices regulated?

I sure know that if ya plug something into a wall outlet and don't have the proper current it will fry stuff, so how is this accomplished remotely?

Could it be that inductive sources will only draw the amount of energy to reach max capacity?

Any idears...?

A few of the articles mentioned that it runs at several MHz, so whatever the output is it's tinkered with many times before it gets to your lamp or whatnot.

I'll try to scan through the actual paper and some presentation material that was sent to me this weekend and muster up a better explanation than the BBC article.

The guy is for real though, in terms of actually being a well thought of professor, having tenure, writing meaningful papers, actually having the proper background to pull this off and the like. Oddly enough I also get the impression he's a big Teslaphile from his comments.

In all the excitement it seems to me that nobody has paused to consider the possible long-term effect to health of spending a lifetime inside buildings filled with eletrical 'beams' - and I'm not talking about electrocution.

your bathed in a magnetic field only with this technology.
thats not the same as a electrical field.
the wavelength allows this system to be used safely
Its resonate at 10Mhz I believe.
Measurements showed that the setup could transfer energy with 40% efficiency across the gap.

Using low frequency electromagnetic waves, which are about 30m (100ft) long, also has a safety advantage according to Professor Pendry.

"Ordinarily if you have a transmitter operating like a mobile phone at 2GHz - a much shorter wavelength - then it radiates a mixture of magnetic and electric fields," he said

This is a characteristic of what is known as the "far field", the field seen more than one wavelength from the device. At a distance of less than one wavelength the field is almost entirely magnetic.

"The body really responds strongly to electric fields, which is why you can cook a chicken in a microwave," said Sir John.

"But it doesn't respond to magnetic fields. As far as we know the body has almost zero response to magnetic fields in terms of the amount of power it absorbs."

As a result, the system should not present any significant health risk to humans, said Professor Soljacic.

WRONG WRONG WRONG WRONG!!!

Im a Master Electrician, and would be happy to debate this with ANYONE!!

Electricity works by a procesess of "bump and move" kind of like if you had 10 golf balls all lined up in a row touching each other, hit the first one and the last one moves, and this is propelled by voltage.

Voltage is "electrical pressure" kind of like how a water tower works with water pressure. Voltage propells electrons through the wire, in essence the wire "moves" or so do the electrons in it.

Air has none (or little) of these properties.

Tesla was able to create electron movement through the air by producing extremly high voltages (25,000v I read some where)at one end and a negative charge at the other as how lightning works, with minimal success This is a far cry from the 120/240 v in your home today.

And such as with lightning if you did get in the way of the current, you would be fried!!!

This isnt radio waves or cell phones people, its electricity!!

Claps for scientists that still ripoff Tesla without giving credit

By taking a $20 crystal radio set from Radio Shack and clipping the leads to the speaker and ramping up the energy through a series of capacitors you could power a light bulb, a small generator....basically whatever you wanted to power.

Harnessing the power of Rush Limbaugh's mouth to light your house...yep, Tesla was ahead of Marconi too. Just don't ask the military where they got the idea for UAV's. Or IBM for the idea of microprocessors.

I know your a Master Electrician but I am a Electronic Engineering Technologist.

and your not correct about Tesla concerning the technology.

Actually its magnetic induction and resonance.
I wish I could make a longer post but thats about it.
There is a difference.
Tesla demonstrated many different things, magnetic induction via resonace being one of them.

Which is different then the other high voltage experiments he did that you mention, which on the surface look like same....a light bulb lit up with no plug in....hence the confusion.

Resonace is the key to many different things Tesla did.
And thats the Word

A standard lighting/appliance breaker is 15/20 amps, A 100 watt light bulb will only draw that 100 watts, so by applying ohms law you can calculate any given load for said circuit. E=I/R, E=voltage, I=current, and R=resistance. A 15 amp circuit or breaker is capable of handling 1800 watts.... 15ax120v= 1800 watts, or 1440 if your going by code(%80 load). So you could put 14 100 watt bulbs on a 15 amp circuit before it would trip.

I sure know that if ya plug something into a wall outlet and don't have the proper current it will fry stuff, so how is this accomplished remotely?

Close, its voltage not current. If you plug in a 120v appliance to a 240v plug it will work great for about 2 seconds. And no you are right you cant do this remotely!!!!

Could it be that inductive sources will only draw the amount of energy to reach max capacity?

Any source be it inductive, reactive, or capacitive on draws what it is designed for, it all bois down to ohms law and the power formulas. And for 3 phase just add a multiplier of 1.732!!

Any idears...?

Those are mine

Ok Im game here, magnetic induction is the basis of transformers right, but those wound coils are millimeters apart! Explain to me how induction can be attained at such vast distances, and when I say vast I meen 4-5 feet!

Just one question, how many volts could a human take at 0.1 microamps, wired or via air? Houses are 120/240V at 80 Amp but a 60W incandescent bulb doesn't need anywhere that amount of Voltage nor Amperage to be lit since 1W=1V*1A.

Safety an issue, the 60W bulb could have been lit by 60000V at 1millamp. Neat yeah, but not overly efficient as the 60000V still have to be generated.
