Talk about being geeked! -- Wireless power

So if we could do this.  I.E. provide electricity to appliances without cords, then what about the idea of electric cars that are powered from the light posts on a road?  Since there would be no gas tax, you could use remote energy meters in the cars that would send use information to the utility, just like current electric meters are capable of.  you would never have to plug in your car, which is the main problem with electric vehicles.

Very intersting.

Does anyone ever stop to wonder what the hell all these EMF do to the human body?????  and then to add remote power into the mix??

I think it is time to move to a deserted island and live off of the land in a grass hut ......

i say power the light posts using the car - save local government from utility bills - it becomes a stealth tax, but you are using the road (and hence the light)...

This is a very cool idea.  I'm interested in seeing what the marketplace can do with it. 

A similar idea came out several years ago of using your house power lines as a communication field.  That never really took off. 

I got a nice cave you might enjoy.  We could be roommates. 

Until someone with a pacemaker enters the room. 

It's going to be annoying to have your credit cards wiped every time you turn on the lights too.

All that being said this would make my job much easier.  Getting power and signal to the end of a robot arm has alway been a pain in the butt.

It's been a long time since my third-quarter physics, but the article makes a (possibly naive) distinction between electric fields and magnetic fields...

I work with structural materials, so I've purged my brain of all that electrical/magnetic stuff...

that is a matter of intensity. 

the wiring in your house is shielded and not in large enough volume to create any negligible electrical / magnetic field.

plus, the whole earth is a magnetic field, i.e. compass

He did and while I read a book about it a few years ago I don't remember the exact ways he was trying to do it. I know he built a tower to try and wirelessly transmit power in new york.

True enough!

Nope.  Most house wiring is NOT shielded, but standard Romex pairs the two wires so that the magnetic flux generated by the current in the hot (black) wire is cancelled by the flux generated from the return current in the neutral (white) wire.  Code usually requires wiring in commercial locations to be enclosed in conduit and this is often thinwall metallic (EMT) conduit, but magnetically shielding wiring is much more complicated than enclosing the wires in metal. 

True enough.  There may be some physiological differences between a static magnetic field (i.e. the earth) and dynamic magnetic fields (which in fact is the basis for Magnetic Resonance Imaging--MRI--technology) 

Don't recall that album/CD.

Now that's just an insult to one of the smartest men to have ever lived.
