A new system has been demonstrated at the TED global conference in Oxford whereby a device can be powered without any need for wires at all via resonance, it is thought the system could mean the end for conventional batteries.
A system that can deliver power to devices without the need for wires has been shown off at a hi-tech conference. The technique exploits simple physics and can be used to charge a range of electronic devices over many metres.

I wonder if it pulls more power from the mains than ordinary chargers.

Wireless electricity has been in the works for many years.. im sure a working model was demonstrated by Intel a few years ago now. And of course, Tesla also demonstrated its viability several times in public demonstrations, though was discredited by his rivals. The problem with Tesla was just how ahead of his time he was... the public, and others in his field, simply didn't believe what he was doing was possible, based on what they had experience of. But the kinds of things Tesla was telling the world was possible back in his day, are slowly starting to resurface now, wireless electricity bein... [More]

Tesla did more than attempt the technology... at his lab near boulder colorado Tesla transmitted electricity wirelessly to a location 26 miles away where he lit an array of lights.. 200 if i remember right. Tesla also wirelessly lit gas filled tube lights in his lab in N.Y.C. 30 years before the 'invention' of neon lights. Tesla worked for Edison for a year improving 'Edison's' DC system. Edison had this nasty habit of taking credit for the inventions and advancements made by the men that worked for him. Tesla and Edison parted on less than amiable terms ,as was the case latter on with J.P. Mo... [More]

Didn't Tesla come up with this technology back in the 1940s - 50s? Yes he did. But I thought that it was a hundred years ago at the turn of the last century. He was way beyond his time and they stoled it from him.

Telsa most likely did, but everyone loved Edison and went with his ideas, it was all a bunch of political b.s. like things usually are. hi Cookes, well, actually we didn't go with Edison's idea , when it comes to electrical generation. Edison was stuck on Direct Current . DC works ok for short distances but loses power rapidly and cannot transmit for long distances. Tesla invented Alternating Current, which is what vibrates in our power lines NOW. Edison, in his battle to promote his DC system, publicly electrocuted an Elephant once with Tesla's AC current to demonstrate how Dangerous AC curre... [More]

To say something complimentary about Edison.. he did finally come to believe that electric cars were superior to internal combustion cars and was promoting a model in 1913. As a matter of fact.. electric cars are nothing new..with the first crude electric carriage being invented by Robert Anderson of Scotland around 1831-39 (the year is uncertain). By 1900 of the 4,192 cars produced in the United States 28 percent are powered by electricity, and electric autos represent about one-third of all cars found on the roads of New York City, Boston, and Chicago.... by 1912 there were about 20000 elect...

Here are some power source ideas: http://www.free-energy-info.com/Chapt11.html Tesla saw the air as carriers of electricity in an insulated fluid or his idea of the ether which he pushed back and forth with coil oscillations. Air was a carrier of electricity almost like sound is carried by air. People following Tesla think he is right and why he must be ignored like the ether which has been deemed nonexistent by the Illuminati. I think my blog has the 1904 article statement about the Tower having millions of horse power double Niagara Falls. With concentrated power and force in the air we migh... [More]

I think I missed two of the past messages but have to say Tesla was black listed from investors and had to work under assumed names. Got this from Bill Lyne, researcher on Tesla, that Tesla worked for RCA and designed some radios. There was a Tesla fan but do not know the connection. A supposed short wave radio that apparently had no power supply was prevalent in the 40s and used by spies in America may have use some Tesla spark gap technology for power.
