Or was it one of the others?? Wireless energy promise powers up By Jonathan Fildes Science and technology reporter, BBC News A light bulb glows whilst receiving power from 2m awayA clean-cut vision of a future freed from the rat's nest of cables needed to power today's electronic gadgets has come one step closer to reality. US researchers have successfully tested an experimental system to deliver power to devices without the need for wires. The setup, reported in the journal Science, made a 60W light bulb glow from a distance of 2m (7ft). WiTricity, as it is called, exploits simple physics and could be adapted to charge other devices such as laptops. "There is nothing in this that would have prevented them inventing this 10 or even 20 years ago," commented Professor Sir John Pendry of Imperial College London who has seen the experiments. "But I think

there is an issue of time. In the last few years we have seen an exponential growth of mobile devices that need power. The power cable is the last wire to be cut in a wireless connection." Professor Moti Segev of the Israel Institute of Technology described the work as "truly pioneering". Energy gap The researchers from the Massachusetts Institute of Technology (MIT) who carried out the work outlined a similar theoretical setup in 2006, but this is the first time that it has been shown to work. "We had a strong faith in our theory but experiments are the ultimate test," said team member Assistant Professor Marin Soljacic. "So we went ahead and sure enough we were successful, the experiments behave very much like the theory." Wireless energy transfer has been thought about for centuries Wireless power promise The experimental setup consisted of two 60cm (2ft) diameter copper coils, a transmitter attached to a power source and a receiver placed 2m (7ft) away and attached to a light bulb. With the power switched on at the transmitter, the bulb would light up despite there being no physical connection between the two. Measurements showed that the setup could transfer energy with 40% efficiently across the gap. The bulb was even made to glow when obstructions such as wood metal, electronic devices were placed between the two coils. "These results are encouraging. The numbers are not far from where you would want for this to be useful," said Professor Soljacic. Power cycle The system exploits "resonance", a phenomenon that causes an object to vibrate when energy of a certain frequency is applied. When two objects have the same resonance they exchange energy strongly without having an effect on other surrounding objects. There are many examples of resonance. How wireless energy could work "If you fill a room with hundreds of identical glasses

and you fill each one with a different level of wine each one will have a different acoustic resonance," explained Professor Soljacic. This was a rudimentary system that proves energy transfer is possible. Marin Soljacic Each glass would ring with a different tone if knocked with a spoon, for example. "Then if I enter the room and start singing really loudly one of the glasses may explode if I hit exactly the right tone." Instead of using acoustic resonance, WiTricity exploits the resonance of very low frequency electromagnetic waves. In the experiment both coils were made to resonate at 10Mhz, allowing them to couple and for "tails" of energy to flow between them. "With each cycle arriving, more pressure, or voltage in electrical terms, builds up in this coil," explained Professor Pendry. Over a number of cycles the voltage gathered until there was enough pressure, or energy, at the surface to flow into the light bulb. This accumulation of energy is why a wine glass does not smash immediately when a singer hits the right tone. "The wine glass is gathering energy

until it has enough power to break that glass," said Professor Pendry. Human interference 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. Socket shortage solutions 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. Future promise The team from MIT is not the first group to suggest wireless energy transfer. Nineteenth-century physicist and engineer Nikola Tesla experimented with long-range wireless energy transfer, but his most ambitious attempt - the 29m high aerial known as Wardenclyffe Tower, in New York - failed when he ran out of money. Others have worked on highly directional mechanisms of energy transfer such as lasers. However, unlike the MIT work, these require an uninterrupted line of sight, and are therefore not good for powering objects around the home. Professor Soljacic and his team are now looking at refining their setup. "This was a rudimentary system that proves energy transfer is possible. You wouldn't use it to power your laptop. "The goal now is to shrink the size of these things, go over larger distances and improve the efficiencies," said Professor Soljacic. The work was done in collaboration with his colleagues Andre Kurs, Aristeidis Karalis, Robert Moffatt, John Joannopoulos and Peter Fisher. HOW WIRELESS POWER COULD WORK 1) Power from mains to antenna, which is made of copper 2) Antenna resonates at a frequency of about 10MHz, producing electromagnetic waves 3) 'Tails' of energy from antenna 'tunnel' up to 2m (6.5ft) 4) Electricity picked up by laptop's antenna, which must also be resonating at 10MHz.

Yes Tesla did this years ago. It is the basis for all electrical circuits that use induction.We all live in the earth's magnetosphere that pulses 7 times a second. It's kind of our mother earth heartbeat. The idea behind radio transmission is to cause a ripple in the pond of the earth's magnetosphere. All radio devices are bad for all of us including but not limited to cell phones. All uses of AC current are extremely bad for us as they impose themslves on our body's electrical system and cause electrical currents to overload our electrical circuits. We are all being biologically changed and genetically modified forever by the massive use of this AC electricity. Here's how it works. The laws of Electricity and Magnetism state that any conductor in the presense of a moving magnetic field will have a current then moving in that conductor. That means that if you take a wire and place it near anything that has an AC transformer operating, that wire will have electrical

current flowing in it. I know that everyone here is smart enough and has a good enough science base to know that what I am saying is true. If you want to something good for world, rid it of all AC electricity and go solar and glowing paints. There are paints now that are 20 times brighter than the old ones and they glow for three days on 20 minutes light. I believe that electricity is our enemy.Peter VV <swpgh01.t21 wrote: Or was it one of the others??

I was one of those childhood geniuses that finished all 12 grades with less than one yearof schooling. I was hanging out at an outdoor hi-voltage test facility at age 7 and talking to test engineers. I made my first lightbulb that same year and numerous radios andseemingly to my child mind, useful contraptions. Whenever the power went out therewas the, "Where's David". I have owned several businesses including but not limited to, a yacht and ship wiring company, a vehicle fleet management company,an electrical repair business, and an automotive electric shop. I have provided electrical consulting and services to Government Agencies and manufacturers and invented products that are in use around the world today. I have had aninterest in the electrical circuitry of all biological organisms for years now, and would be drawing a blu-print for a yacht or ship and switch over to studying the electrical circuits of a salamander.

I moved up to neurology and anatomy of the human being and with my electrical background, my genetics having a high mechanical aptitude from a diesel mechanic father, and medical bent from my chiropractor grandfather, started studying the works of the great neurologists. That's when I discovered how harmful AC electricity is.I of course was not the first. So much research has been performed and the military made changes to their vessels correspondingly before I was even born 41 years ago. I know ony a fraction of what could be known about the topic.But I know enough to know the math and the math never lies in electronics. You raise the question, so what is left? That's a good question, and I think that it's too late to undo everything that's been done but that progress toward a better environment can be achieved through the use of low wattage appliances and phosphorescent pigments added to paint to provide lighting. Solar energy including both water

heaters and electrical panels, stopping the use of all AC devices including television, computer and household appliances. Tell that to the little old lady in Chicago during a deep freeze that your going to turn off her heat. So you can see our problems. I believe that pretty much everything that has been invented has turned out to backfire on us humans. The wheel for instance, scientists have found peizo-electric crystals in our bones that generate electricity when we walk. Not when we drive or ride a bicycle. We human beings are the only creatures on planet earth that are creating an environment that is hostile to our own survival.

Hi Peter

Hey - you've largely defined me there (all hail the mighty spud goddess!)... dunno - I appreciate what I can do with electricity, but I don't like the way it's produced, and if ever I can afford to, I plan to live entirely off solar and wind powered electric...
