Wireless Power and Electricity Coming Soon!
Wireless power and electricity
Chinese manufacturer Haier decided to steal the show at CES this week by showing off a 32-inch TV set at CES that is running completely wirelessly. And when we say completely... we mean COMPLETELY. In addition to wireless HDMI transmission the 32-inch TV is also receiving wireless POWER. Look, Ma, no wires. No, seriously.
Haier is working with WiTricity's wireless electricity technology and is setting themselves up to be the first to deploy an actualTV set with true embeeded wireless power within the next couple of years. While the shipping products may take a while to shrink down in cost and size to marketable levels, the technology was on display for anyone in the press to see.
WiTricity uses specially designed magnetic resonators in both the device and the power source to efficiently transfer power through what it refers to as a "magnetic near-field". Once you tune the two power resonators together they can transmit electricity - and do it without burning down the house or causing brain tumors (bonus!)
Beta News even has some video of the wireless power system.
This approaches allows for safe power transfer as well as extended reach many times the size of the device. It can also move around objects in the way, and Haier demoed the model with obstructions so as to ensure the system doesn't require a pristine setting in order to work.
Last year, WiTricity showed a proof of concept, but this year;'s CES Exhibit was the first time they demoed a working model in public.
This will truly redeine the concept of what a "wireless" product means. If the system can power more efficient televisions and other media devices wirelessly, then interior design has just taken a whole new step forward.

It's been consistently shown that there is a higher concentration of brain tumors (cancer) around high power electrical lines, say with 420KV, authorities have never accepted this fact but it seem to be too much of a coincidence that cancer should be much more common around strong magnertic fields, and the must be a reason for this
now the emagnetic fields around these installations would be much less than around a 420KV power line, but they will still be of significant nature…. and sitting so close to these magnetic fields….
Not sure this is good… or healthy for that sake
Field strenght decreases with the square of the distance. You most likely experience a greater magnetic field standing next to your speakers or using a cell phone than standing under power lines. Time to get rid of the HT and phone
First, did ya look inside the tv for batteries? Joking aside, isn't the development of smaller, faster, stronger, cooler batteries and lighter, more efficient electronics a more likely implimentation?
Second, if this program gets off the ground, we're gonna have billions of migratory birds flying in little, lost circles over your house, looking for a place to, uh, reproduce and feed. They use magnetic lines of flux to navigate on their migrations. “OH NO! Duck! Honey, here comes that goose again…the one that keeps crapping on the Chrysler.”

Nikola Tesla would be proud!
Indeed Nikola would be proud, but there's a problem. Broadcasting electricity works, but electronic waves don't know what they are supposed to electrify. Any conductor within range will pick up a charge so not only the TV, but also nearby wires, the kid's braces, the dog's collar chain, the metal cabinet that the TV sits on will also be charged up with electricity. You will need to remove your metal belt buckle and sit there in rubber boots, but, you won't need to plug in the TV.

Actually, flux lines don't conduct the current, they induce it in the device that is affected by them. For this reason, I want to see data about how strong the magnetic fields in that area are and what affect they'll have on other things/people. The field diminishes via the inverse square rule and if any appreciable distance is between the pieces, anything between them will be affected.
Not entirely true. Flux lines can only induce current in a collapsing field. In this case, the field was not collapsing, it was generated by a magnet. Part of the experiment involved finding what part of the magnetic field actually carried the current, and, as you would think, the strongest part or lobe of the flux field carried it. If the field was diminished in any way, the ability to carry the current ceased. You are correct in that a flux field lessens with the square of the distance.
