Is it physically conceivable the possibility of transmitting electricity between spatially separated objects (e.g. a few meters) in a wireless way?
He was an amazing inventor, but he couldn't turn his ideas into a profitable product, and as a result, died broke.
Electricity is not "transmitted" in the scenarios described.
That would be a "spark gap" or "lightning"
Rather, it's the transmission and absorption of EM waves which are then locally coverted to moving electrons in a medium sensitive to do this.
A radio antenna is no more receiving actual electrons from an outside source than a solar cell is.
This is so true, and the losses are so great that I still cant figure out why people are spending so much time on it ??? pumping a zillion Watts into a transmitting antenna just to see a few mW of induced power in the receiving cct
I really dont get it... it definately isnt economic
But all of these are again very short distances, most would use the term inductive charging as opposed to wireless since the electromagnetic waves are not meant to propagate.
Ahhhhhh and there-in is the truth to what is really going on ;) exactly There are more and more products around the home using such systems from my electric toothbrush for charging its battery to the electric jug for boiling water.
But I get the impression from what I see on the various forums around the net, that people are expecting to be able to wirelessly transfer significant power levels over significant distances. I really wonder if they understand the drop off of power levels cuz of the inverse square law [PLAIN]http://en.wikipedia.org/wiki/Inverse-square_law[/URL] [Broken]
