From an article in Gizmag dated 8/20/09, entitled: Korean Electric Vehicle Solution - Online Electric Vehicle (OLEV) from KAIST... the OLEV picks up charge using a non-contact magnetic charging method (where a power source is placed underneath the road surface and power is wirelessly picked up on the vehicle itself) so it doesn't matter if the car is moving or parked, it still receives power... up to 80% power conveyance with a 1cm gap between the vehicle and the power line.

Absolutely J.P. Morgan put a stop to wireless power... And Tesla was awesome! Wardencliffe tower was in Colorado Springs, CO I heard it was for sale for $1.6M but I don't know if that's just the building and land, or if the tower is actually still there... The best part about it, was that you could harness electrical energy right out of the atmosphere during lightning storms!

The general idea as I get it is that you'd have an appliance in your room beaming out the magnetic field. Your portable devices would have a coil to harness that magnetic field, converting some energy back into electricity. Unless electricity is broadcast by a public utility, you'd still need a battery if you leave the house. Think WIFI hot spots, but broadcasting electricity instead.

He was able to power florescent lights for some distance.

They should have given Tesla more credit as he did his successful test in 1893.

I wouldn't use it if it's considerably less efficient than what it's trying to replace. I don't mind routing wires if it's 50% more efficient than wirelessly. Not only does it cost more for the rest of the parts (compared to wires), I can always just make a hole in the wall and run it down the cavity or cut a channel in the bricks to run wires down with something flush against the wall to cover.

True, but most devices don't use anything like 120VAC, they use more like 5 - 12VDC. TV's/Monitors, etc not included.

Electric fields and magnetic fields are closely related, which is why they are grouped into the study of electromagnetism. Electric currents induce a magnetic field, just as magnetic fields induce electric currents. In this case, electric current is generating a magnetic field, which is then collected and used to induce current again. The electric field remains in the source (the actual wire). I really hope you're not an EE.

I'm wondering if any of the people that keep bringing up Tesla's wireless electricity transmission experiments have any idea of what was actually involved. Do you? Tesla was experimenting with charging up the air with a big electrical emitter, basically creating an electrical storm. Tapping that power would be a simple matter of putting up an antenna. Sounds great until you get electrocuted by a flag pole, plus it wasn't as efficient as wires, plus the quality of the power would be abysmal.

How much energy do we lose by transmitting it through cables? Forgive my ignorance, I honestly don't know. I recall he said 50% was far less than we lost by using batteries, so he could at least use it in all areas of daily life in which we currently use batteries. That'd still cover quite a bit!
