Free Worldwide Energy - Nichola Tesla

Nikola Tesla was an unrecognized genius before his time. He believed that the earth itself could conduct energy around the world and be tapped for free anywhere. Doesn't it seem ironic that such a device existed back in the early 1900's. Tesla had the right idea but the Government could not find a way to place a meter on free energy. It seems such a shame that we cannot work for mans benefit instead of a monetary benefit of a few people and governments.

"Tesla believed this to be a simple procedure, and later confirmed through experimentation, that the Earth conducts electricity naturally, much like a metal ball. Tesla hypothesized that Earth could be charged from a single location and energy could be safely extracted from any other point on the globe's surface.

The Earth could be pumped with electricity and anyone on its surface could remove it by simply placing a wire into the ground. This energy could be withdrawn in unlimited amounts for unlimited uses, free for all the world's people!"

Resonator Fields and Transmission Line Modes.

When he (Tesla) speaks of tuning his apparatus until Hertzian radiations have been eliminated, he is referring to using ELF vibrations: "...the Hertzian effect has gradually been reduced through the lowering of frequency."3

"...the energy received does not diminish with the square of the distance, as it should, since the Hertzian radiation propagates in a hemisphere."3

He apparently detected resonator or standing wave modes: " ... my discovery of the wonderful law governing the movement of electricity through the globe... the projection of the wavelengths (measured along the surface) on the earth's diameter or axis of symmetry... are all equal."3

"We are living on a conducting globe surrounded by a thin layer of insulating air, above which is a rarefied and conducting atmosphere... The Hertz waves represent energy which is radiated and unrecoverable. The current energy, on the other hand, is preserved and can be recovered, theoretically at least, in its entirety."4

As Dr. Corum points out, "The last sentence seems to indicate that Tesla's Colorado Springs experiments could be properly interpreted as characteristic of a wave-guide probe in a cavity resonator."5 This was in fact what led Dr. Tesla to report a measurement which to this day is not understood and has led many to erroneously assume that he was dealing with faster than light velocities.

And whan, pray tell, would be used as ground if the ground was charged?

Tesla was a genius, but today is unfortunately remembered in more in mythology than in history.

I am in no way an expert on Nikola Tesla and his theories but apparently the earth below our feet would be charged while he states that we are surrounded by a thin layer of insulating air which would prevent humans from receiving the electrical contact.

According to Tesla, you would have to put a conducting wire "down" into the ground in order to utilize the preserved and non-diminishing electrical charge.

But you will have to do a great deal of reading to understand exactly what Tesla was talking about as only now are people beginning to understand his genius concepts. It is true that the petrochemical industry and oil producing countries have a great deal to loose from 'free energy to the world.'

Apparently some studies indicate that there is a highly conductive D" layer in the earth deep outer mantle.

http://www.nature.com/cgi-taf/DynaPa.../366453a0.html

Nature 366, 453 - 455 (1993); doi:10.1038/366453a0
Electrical conductivity of the Earth's lower mantle

T. J. Shankland, J. Peyronneau & J.-P. Poirier

THE electrical conductivity of the Earth's lower mantle constrains both the propagation to the surface of geomagnetic disturbances in the core and the nature of core–mantle coupling. Extrapolations of laboratory measurements on materials representative of the lower mantle agree weakly1,2 or not at all3,4 with recent geophysical models5–8 of lower-mantle electrical conductivity based on variations of magnetic and electrical fields measured at the Earth's surface. Here we report d.c. conductivity measurements on samples with compositions approximating that of the lower mantle, at pressures of 1.2 to 40 GPa and temperatures in the range 20 to 400 °C. Our results agree with some of those obtained previously1,2. But in contrast to this previous work, we extrapolate the results to lower-mantle conditions by adopting a functional form for the conductivity that incorporates the effect of pressure as well as temperature. The resulting estimates of conductivity are in agreement with the geophysical determinations5–8. We find that, because of a very weak dependence on temperature, pressure and composition, the conductivity is likely to vary by no more than about a factor of five across the entire lower mantle, reaching a maximum value of only 3–10 S m-1. Lateral temperature variations as large as a few hundred degrees will therefore be hard to detect geophysically, and the compositionally distinct D" layer at the base of the lower mantle remains the only possible location for a highly conducting layer.

Another article from NATURE indicates electrical conductivity at lowr mantle conditions.

Electrical conductivity of silicate perovskite at lower-mantle conditions

http://www.nature.com/cgi-taf/DynaPa...5493a0_fs.html

TOMOO KATSURA1, KIMINORI SATO* & EIJI ITO1

1 Institute for Study of the Earth's Interior, Okayama University, Misasa, Tottori-ken 682-0193, Japan
* Present address: National Institute for Research in Inorganic Materials, Tsukuba, Japan

Geophysical models of the electrical conductivity of the Earth's mantle based on the observed variations of electric and magnetic fields at the surface of the Earth yield estimates of about 1 S m-1 for the conductivity of the uppermost lower mantle,. But laboratory conductivity measurements on silicate perovskite (thought to be the dominant constituent of the lower mantle) at high pressures have given conflicting estimates of mantle conductivity, ranging from less than 10-5 up to 1 S m-1 (refs 3–6). Here we present measurements of the electrical conductivity of perovskite in a multi-anvil press at conditions appropriate for the uppermost lower mantle (pressures up to 23 GPa and temperatures up to 2,000 K). We find that the geophysical estimate of lower-mantle electrical conductivity can be well explained by the conductivity of the perovskite component of a low-oxygen-fugacity mantle composed of pyrolite (the assemblage of mineral phases thought to broadly represent that of the Earth's mantle), assuming a standard geotherm. Our results also indicate that the temperature dependence of perovskite conductivity at lower-mantle temperatures and pressures is significantly larger than shown previously; extrapolations of low-temperature conductivity measurements to the higher temperatures of the lower mantle should therefore be treated with caution.

Power is generated by using the potential difference between what is supplied (generated) and ground. If you charge up the Earth itself, you still need some neutral (or at least different) level of charge to draw any current from it.

This discipline is not my area of expertise.
It seems that presently available electrical conductors and materials used to draw the stored charge for use above the ground should be readily available if Tesla's premise proved correct.
It seems that there has been some recent studies of lower mantle conductivity as previously described.

"We find that the geophysical estimate of lower-mantle electrical conductivity can be well explained by the conductivity of the perovskite component of a low-oxygen-fugacity mantle composed of pyrolite (the assemblage of mineral phases thought to broadly represent that of the Earth's mantle), assuming a standard geotherm."

Do these schemes include the actual GENERATION of the power or only the distribution. It is pretty easy to transmit power, every radio station does it. We could conceivably transmit power to every household in the world. Unfortunately this type of distribution is very inefficient and even worse there is no way to BILL for use. It is great for the consumer but it would sux to be the supplier. Who do you know that is willing to provide a very expensive service for free?

TESLA TODAY

Nikolas Tesla the man who makes most everything we do today functional is forgotten.

http://www.geocities.com/Area51/Shad...la/hacker.html

Edison, who wasn't near the inventor Tesla was, but who was a better businessman, is well remembered as is his General Electric. Still, let me list a few of Tesla's works just so you'll understand how bright he was. He invented the AC motor and transformer. (Think of every motor in your house.) He invented 3-phase electricity and popularized alternating current, the electrical distribution system used all over the world. He invented the Tesla Coil, which makes the high voltage that drives the picture tube in your computer's CRT. He is now credited with inventing modern radio as well; the Supreme Court overturned Marconi's patent in 1943 in favor of Tesla.
Tesla, in short, invented much of the equipment that gets power to your home every day from miles away, and many that use that power inside your home. His inventions made George Westinghouse (Westinghouse Corp.) a wealthy man. Finally, the unit of magnetic flux in the metric system is the "Tesla".

Tesla got to thinking about resonance on a large scale. He'd already pioneered the electrical distribution system we use today, and that's not small thinking; when you think of Tesla, think big. He thought, let's say I send an electrical charge into the ground. What happens to it? Well, the ground is an excellent conductor of electricity.

For a few moments, there in Colorado Springs, he achieved something never before done. He had used the entire planet as a conductor, and sent a pulse through it. In that one moment in the summer of 1899, he made electrical history. That's right, in 1899 - darn near a hundred years ago. Well, you may say to yourself, that's a nice story, and I'm sure George Lucas could make a hell of a move about it, special effects and all. But it's not relevant today. Or isn't it? Hang on to your hat.

The SDI and the Tesla Coil

Last month we talked about an amazing hack that Nikola Tesla did - bouncing an electrical wave through the planet, in 1899, and setting the world's record for manmade lightning.

We've always assumed the ground is an electrical sinkhole. So, with our three-pin plugs we ground everything - the two flat pins in your wall go to electricity (hot and neutral); the third, round pin, goes straight to ground. That third pin is usually hooked with a thick wire to a cold water pipe, which grounds it effectively.

Tesla proved that you can give that ground a terrific charge, millions of volts of high frequency electricity. (Tesla ran his large coil at 33 Khz). Remember, the lightning surging off his Coil was coming from the wave bouncing back and forth in the planet below. In short, he was modifying the ground's electrical potential, changing it from an electrical sinkhole to an electrical source.


How much do we owe this genius today? Mad man, I don't think so....

I agree with Integral. This scheme involves no more than a power distribution network, and a very poor one at that.
To "charge" the earth with any measurably useful non-local extracting force would require a placement of an earth-charging generation device likely to boggle the imagination, and likely far surpassing any ability we have.
Furthermore, what would be the point?
A considerable amount of energy would be required to charge the earth, for one, and the earths exceptionally poor conductivity would create current losses far exceeding the rationality of efficient distribution.
In my opinion, the idea is dead from the start.

Actually the earth's mantle is constantly being electrically charged by many external forces such as the grounding by earth's electric users, and many natural forces that have been going on since the formation of this planet such as solar flares. Electricity is constantly being released from the earth by the action of thousands of hourly lightning events around the world sending the earth's charge into the atmosphere.

Furthermore, what would be the point?

The point? If some construct could be devised to draw the earth's electric charge from the mantle, how would governments and corporations charge for everyone's access to free unlimited energy sources. The nature of lightning seems to be doing a very efficient job many times a minute around the globe.

Electrical conductivity of olivine, wadsleyite, and ringwoodite under upper-mantle conditions

Xu Y, Poe BT, Shankland TJ, Rubie DC.

Bayerisches Geoinstitut, Universitat Bayreuth, D-95440 Bayreuth, Germany.

Geophysical models show that electrical conductivity in Earth's mantle rises about two orders of magnitude through the transition zone in the depth range 410 to 660 kilometers. impedance measurements obtained on Mg1.8Fe0.2SiO4 olivine, wadsleyite, and ringwoodite at up to 20 gigapascals and 1400 degreesC show that the electrical conductivities of wadsleyite and ringwoodite are similar and are almost two orders of magnitude higher than that of olivine. A conductivity-depth profile to 660 kilometers, based on these laboratory data, shows a conductivity increase of almost two orders of magnitude across the 410-kilometer discontinuity; such a profile favors a two-layer model for the upper mantle. Activation enthalpies of 1.2 to 1.7 electron volts permit appreciable lateral variations of conductivity with lateral temperature variations.
In my opinion, the idea is dead from the start.

Interestingly that is exactly what many physicists said when Boehr came up with a concept known as QM.

But that sort of charging is disorganized. You can't draw power from the ground after a lightning strike.

Have you been listening?

There ain't no such thing as a free lunch.

TANSTAAFL

Charging the Earth may provide free power for the end users, but it A) Will most certainly NOT be free for the people who do the charging, and B) Would be horribly inefficient due to the resistivity of earth.

Why would a company spend their money to charge the Earth so other people can feed off of it for free? Why would they use the Earth when power lines provide orders of magnitude lower resistance and power losses are proportional to resistance?

In my opinion, the idea is dead from the start.

That doesn't mean that every idea which is dead from the start is revolutionary. The vast majority are merely dead from the start.

Lightning produces a relatively insignificant amount of electricity. Even if it could be reliably harnessed, it wouldn't do much to help the world energy situation.

After a lightning strike? How do you come to the conclusion that any electrical current charge is disorganized or organized with the earth being a capacitor? The earth having about two orders of magnitude through the transition zone in the depth range 410 to 660 kilome which is propelling a current of quantized electrical charges, electrons, through a load. The heavier this load, i.e. the lower the electrical resistance the more current would be drawn from any point on the earth. Actually there is such a thing as a free lunch when it comes to the irreducible complexity you get for free in your own cellular existence as an organism.

Charging the Earth may provide free power for the end users, but it A) Will most certainly NOT be free for the people who do the charging, and B) Would be horribly inefficient due to the resistivity of earth.

Maybe someday, the world's ever increasing need for electricity in all nations (rich and poor) will result in an altruistic consortium of nations using natures own (Energy Towers) physics to supply an endless supply to the betterment of mankind. Albeit the world has never demonstrated any altruistic proclivity toward their fellowman in history.

Apparently Nikola Tesla had no trouble passing a significant electrical potential through the earth's resistance in the early 1900s. With enough money and the advancement of technology, even the earth's resistivity should eventually be overcome.

Why would a company spend their money to charge the Earth so other people can feed off of it for free? Why would they use the Earth when power lines provide orders of magnitude lower resistance and power losses are proportional to resistance?

When in the course of advanced technology, power lines provide a lower order of electrical potential than an earth mantle with significantly reduced resistance, then mankind might see its way to feeding and supplying power to the entire earth.

But not in our days......

That doesn't mean that every idea which is dead from the start is revolutionary. The vast majority are merely dead from the start.

I have learned to NEVER say the words; always, forever or never when it comes to the potentials in the mind of man.
