As I hear it, both Tesla and edison were dependent upon Carnegie for funds to continue their experiments.
Edison worked on dc current, transmitted by wire.
Tesla worked with ac, transmitted sans a wired grid.
Carnegie, a welthy businessman could see that the source of power could easily be identified by the wires.
Hence, profit could be made, because the source was easily identifiable.
Tesla lost his funding... even though his concept was superior.
Then, it became necessary to convert the fledgling systems operating in dc mode to ac, (tesla's concept),
because it was found to be superior.
I am not so sure wireless transmission of energy is such a good idea.
There have been identifiable anomalies and significant health problems in humans with range of
spurious emissions from city transformer systems, and in big buildings near the power rooms.
Not good to put your poodle in a microwave...
It's also known that high frequency radio waves affect vision first... kinda cooks the eyeballs.
There was once quite a bit of concern that cell phone use might be a potential threat, but it has been declared that the power evels are low enough that it should not be a problem.
Yet there's a lot of companies with many $'s riding on that question.
Some handheld ham tranceivers have an output as much as 5 to 7 watts.
Extensive use could cause damage...
I think I'd just as soon keep it a wired world!
