Ask Slashdot: Could Nikola Tesla's Wardenclyffe Tower Have Worked?
dryriver writes: For those who are unfamiliar with the story, from 1901-1902, inventor Nikola Tesla had a 187-foot-tall experimental wireless electricity transmission tower called the "Wardenclyffe Tower" built in Shoreham, New York. Tesla believed that it was possible to generate electrical power on a large scale in one part of the world and transmit that electrical power to electrical receivers in far away parts of the world wirelessly, using parts of Earth's atmosphere as the conducting medium. Tesla had huge problems getting the project financed -- powerful banker J.P. Morgan didn't play along and U.S. President Woodrow Wilson didn't help a pleading Tesla either. An excerpt from a Wardenclyffe documentary shows the tower finally being dynamited and sold for scrap in 1917. The Wardenclyffe Tower never reached operational status; wireless electrical transmission between continents never happened; Tesla became an emotionally broken man who died regretting that he did not manage to finish his life's work; and to this day nobody knows exactly how the Wardenclyffe Tower was supposed to function technically. To the question: Do you believe that Tesla's dream of electrical devices anywhere in the world essentially being able to draw electrical power from the sky with a relatively simple antenna could have worked, had he gotten the necessary funding to complete his experiments?
EM radiation from the wireless source drops off according to the inverse square law. This has been figured out in the time since Tesla. So no, Tesla's tower could never have worked. Beyond a short distance (like the inches between an RFID card and its reader) power transmission is not feasible because of, you know, physics.

What is believe? Either the math / physics works or it doesn't. Science is not an opinion based enterprise
It's about a belief whether there might any physical principle for wirelessly transmitting electricity that Tesla knew about back then and we don't nowadays.
It might be possible, but I believe it unlikely.
People freak out about a few mW of RF being pushed though cell phones. Can you imagine the freakout if someone said they were going to build giant towers pushing millions of watts of low-frequency RF blasting out in all directions?
