Wireless promoters misread Tesla

Yesterday my friend John W. sent out a question to Tesla fans. John had read about the success of a wireless venture called WiTricity two years ago, and this week he saw an article about it in The Economist: “Power From Thin Air”.

“All good,” John wrote in an email, “except I am concerned about the more prevalent ‘wireless’ waves coursing through my body.  More study of its safety is needed before we can adopt such a technology.  Or does anyone know of such a study?”

I don’t, but I emailed a scientist who has thoroughly studied Tesla’s patents and has recreated Tesla’s experiments. He replied, “What they are doing with receiving energy from radio waves is DEFINITELY NOT what Tesla was doing at all.

“Sending transverse energy; i.e. radio waves, from the current radio system is definitely dangerous to our health.  Tesla wanted nothing to do with the transmission of Hertzian waves and definitely did not send energy through the air or ground with radio waves made out of Hertzian forms of any kind.

“What he was doing was sending longitudinal waves through the air and ground (mainly the ground). This is a very efficient way to send energy over long distance and usually ends up with more energy been received than sent — although I think that Tesla made that system obsolete by the mid 1920’s.”

In a following email he added, “I do support energy scavenging from free Hz waves (ambient radio waves) but I do not support making more to charge a device.  Although it is a very feeble way to get energy it is still free and available….so why not use it.”

Frontier scientists have been studying Tesla’s real discoveries and recently gained insights on what Tesla may have used to power his legendary car. I have hope that they will have a similar operating device soon; as you know it is urgently needed to free people from King Oil.

Excerpts from the June 21 article in The Economist (U.K.), claiming a Tesla technology:

“Anyone whose mobile phone has ever run out of juice…will like the idea of getting electrical power out of the air. The notion is far from new. A little over a century ago, the inventor Nikola Tesla drew up ambitious plans to transmit electrical power without wires. He carried out a series of experiments in which electric lights were illuminated via electrostatic induction, by connecting them to metal sheets suspended in a strong electric field produced by a distant transmitter. In 1898 he proposed a ‘world system of giant towers that would form both a global wireless communications network and a means of delivering electricity over large areas without wires.”

”The construction of the first such tower, the Wardenclyffe Tower, on Long Island, began in 1901. Tesla’s backers included the financier J.P. Morgan, who invested $150,000. But before the tower was completed, Morgan and the other backers pulled out. They worried that the delivery of electricity through the air could not be metered, and there would be nothing to stop people from helping themselves.”

”But has Tesla had the last laugh after all? Today several firms-including Fulton Innovation, eCoupled, WiTricity and Powercast-are pursuing various technologies that deliver electrical power without wires (though over shorter distances than Tesla had in mind). WiTricity has demonstrated the ability to send enough energy across a room to run a flat-screen television using its approach, called ‘resonant magnetic coupling. This is different from Tesla’s approach, but the firm’s founders have acknowledged his pioneering work.”

”In the long run, however, it may be Morgan who is vindicated, as researchers find ways to pull power out of the air without paying for it-a technique known as ‘energy scavenging or ‘energy harvesting . It is already possible to power small electronic devices, such as wireless sensors installed in buildings and industrial machinery, using a dedicated microwave transmitter nearby. The sensors pick up the microwaves with an antenna and convert the signal into electrical energy. But as power requirements drop and energy-scavenging technology improves, it will become increasingly practical to power these and other devices using just ‘ambient energy-the sea of existing radio waves produced by television, radio and mobile-phone transmitters…..”

So — harvesting the radio waves that are already in the air is fine, but adding to the ambient electrosmog by building more transmitters  is not helpful to our health.



  1. m. thompson says:

    The current wireless methods being used to power small devices are probably very closely associated with Tesla’s famous lab and lecture demonstrations. However, he referred to those demonstrations as something along the lines of conjurers’ tricks not at all suited for real power transmission; while his earth transmission system, which is a somewhat different application of resonance, was. This is all clearly stated in his writings. Tesla was a great teacher.

    His later research into the harnessing of cosmic energy seems to have been a logical outgrowth of his earth system research, which allows the extraction of energy from the surrounding ‘medium’ via a somewhat more sophisticated arrangement, while eliminating the need for input, since the entire cosmos is involved in supplying the energy involved. Same process, different level. It helps to look at his comments on the underlying cause of radioactivity to really get an idea of what he was saying.

    In regards to safety, Tesla again was very clear on what frequencies were harmful and which were not. Basically, once you progress past a certain level into higher frequencies, there is no danger biologically speaking. It seems to be a question of resonance: the more gross the structure the lower the harmful frequencies. This of course is a separate issue from radiation, the projection of a particle of mass along a pathway, which is the longitudinal aspect people speak of. This differs from resonance of a mass much like an arrow in flight differs from a quivering blob of jelly.
