RCA Airnergy

[lamare]

Over at Slashdot, there's a discussion about wether or not the RCA Airnergy device is "snake oil" or not:

Slashdot Ask Slashdot Story | Is RCA's Airnergy Snake Oil?

The device is basically burned to the ground, because it cannot work, since if you calculate how much energy you can recieve with Herzian waves, you can forget receiving anything useful.

However, if Meyl and Tesla are right, then this could be very similar to a miniature "amplifying transmitter", or, better: a receiver for longitudinal waves, tuned at the transmission frequency of WiFi devices, which probably transmit a significant amount of longitudinal waves, because the antenna's that are used are not of a very good quality.

I have commented over there, with some references to Prof. Meyl's stuf...

This may be a very interesting device. If it indeed works, scholars are going to have a very hard time maintaining that longitudinal waves are impossible...

Slashdot, for all it's patina of being forward thinking people is really a reactionary hotbed of people with their minds firmly planted in the conventional. It's no surprise to me that it's being panned there.

Considering Prof. Dr.-Ing. Konstantin Meyl of Germany showed similar stuff years ago, it would be interesting to see what would happen if someone just copied this thing and started selling it... Could RCA win any Patent Infringement suit? Prolly not if the basic tech was shown to be Open Source. Only a few small changes in circuitry would allow it to be considered "not a direct copy" then.

Any patent number? I didn't see one in any of the articles.

This is simple enough that anyone here can make it and try it out to see
if it works.

There is some information over at rexresearch on the circuit shown in the video referenced by Aaron. It's described as "two oppositely polarized voltage doublers."

Also of note is this page on an IC that would be great in this application or with an earth battery:

Also mentioned in another thread was a joule thief using a TN0702 jfet.

antenna

PJ,

I have some antenna wire about 60 feet long hung over the roof of
someone's house about 25' in the air. It is STILL THERE after 8 years
or something. I think it has been there so long they don't even notice it
and I didn't even remember it until I looked at that Tate stuff with the
antenna. lol Thanks for the reminder!

I think Perrault had something like this on a page and it was in Peswiki
and I remember there was some heated exchanges about this whole deal.
Anyway, with that experiment, I did not get the results I wanted but of
course there was potential measurable but I'm in a better position now to
maybe get what I wanted from it, which was at least a few hundred volts
in a capacitor.

I need to go yank that down and set it up closer to me.

@PJ,

These are using "normal", Herzian radio waves, which are very inefficient for power transmission.

It may be possible to build a reciever similar to the recievers in Tesla's magnifying transmitter or the "replications" by Meyl and/or Stiffler that would be "connecting" to the transmitter using longitudinal (or scalar) electric waves. According to Meyls theories, these would be able to become tightly coupled, capacatively, to the receiver and be much more efficient for the transmission of power.

See this picture, which is a very common picture showing the electric field between two opposite charges:


As you can see, the electric field lines (blue) and thus the electric field is not evenly distributed across space. It is concentrated in between the charges. So, if you assume two "capacitor plates" that are resonating out of phase, you would get a similar concentration of the, in this case, oscillating electric field between the opposing charges on the plates.

In other words: if you have two coils resonating out of phase, and on top two capacitor plates that are always oppositly charged because they are out of phase, there would be a concentrated "beam" of electric field lines. This can apparantly transfer energy between the two coils trough the open capacitor, by means of a pure electric wave, a longitudinal electric wave.

Interesting paper on Meyls experiment

I found this rather critical paper on Meyls experiments, which is worth reading, because the author makes some good points:

http://www.info.global-scaling-verein.de/Documents/ElectricScalarWaves-ReviewToMeylsExperiment01.PDF

The force of a Hertz dipole on a charge in great distances is in close approximation equal zero, what means, that no far reaching longitudinal forces are expected. An other thinkable construction of a transmitter is a single oscillating charge (similar to a first order sound wave transmitter). But unfortunately it was never possible to build a single electric charge oscillating in time. This is the law of the conservation of charge. And for this reason every transmitter consists at least of two opposite polarities which are mutually charged and recharged. Therefore each antenna has two opposing charged poles which are changing in time. But everywhere we have two opposing charged poles the longitudinal forces of this poles on an other charge having the same distant to both poles are canceled out perfectly. Only the transversal forces can “survive” this cancellation in far distances.

Another interesting paper:

Mervace

I forgot about this one..created quite a buzz a while back.

Mervace's pepetual mobile. He came out saying it was tapping power
wirelessly from a CB radio or something. But, maybe it really wasn't and
he was discouraged that nobody could figure it out and said that to throw
people off... but if it was, then that is tapping enough to power an
electromagnet to do work.

Hi Aaron

It wouldn't be hard to hide a battery or 2 in that thick base of wood.
