"Just hook up hundreds of thousands of humans in series-parallele and you can... "
That is not too far fetched if you live in NYC
But seriously, you need to read a little more about Tesla's experiments to really understand some of his radical ideas that go against conventional wisdom..

 

"My guess is that the total energy around is in the range of mili-watts, but surely less than one watt.
And this is just the raw energy that is out there. The efficiency of using it will be very low even with a complex design.
What sort of device are you thinking about to power?"
For Uon and Kubeek,
Remember the Crystal Radio? With no local power source, it drove ear phones very nicely to receive HF frequencies generated thousands of miles away.

I've read plenty about Tesla's work. I've readly plenty hyperbole from Teslaphiles as well. They are as different as the history and hype of Davy Crockett, or King Arthur. Tesla was never exempt from the Laws of Nature, he simply looked for new ways to apply them.

Headphones produce dozens of of dB SPL per milliwatt i/p. The threshold of human hearing is zero dB SPL. Nothing secret or amazing here, except maybee human physiology.

 

What does "rechannel" mean today?

In context I would suspect it means "divert the energy in some other way" or perhaps "channel the energy again".

This is an obsolete thread.

 

Water, perhaps? (Not a technology, but certain one of the best for EM field absorption).

Really?? sounds pretty interesting, plz elaborate!

 

I've heard that a mobile company will use the radio signals surrounding us to charge the cellular. This is 99% true. I have not read it myself, i just heard it, but from a trustful source

 

While it sounds good, it's not too plausible, unless you happen to live next to a radio station. There really isn't that much energy out there, and if there is, it was likely intended (and paid for) to do something else.

In the USA this is called "Theft of Service", and is a misdemeanor.

As for this thread, Flamewarriors refers to this as Necromancer.

 

"Where a calculator on the ENIAC is equipped with 18,000 vacuum tubes and weighs 30 tons, computers in the future may have only 1,000 vacuum tubes and weigh only 1.5 tons."
Popular Mechanics, 1949

You never know what they have in mind....

 

Really?? sounds pretty interesting, plz elaborate!

Think of dielectric heating (for example, a microwave oven). Issues relating to the penetration depth will limit the efficiency in real applications to the RF and microwave frequency range. The are many factors that influence E-field absorption, but as the humble microwave proves, the scope is quite wide.
