Tesla Generator – a Self-Sustaining Electricity Harvester

tesla-wireless-transmissionBefore seeing how the Tesla generator works it would be worthwhile to have an idea of how any electricity generator, even in theory, could be capable of producing a self-sustaining current.

This has been clearly explained by Walter M. Elsasser in a Scientific American article (May 1958) titled “The Earth as a Dynamo.”

Elsasser has modeled the earth-dynamo, conveniently for this explanation, on the Faraday generator of a metal disk spinning over a bar magnet placed at the edge of the disk. He notes, also, that the bar magnet could be replaced by an electromagnet which could get its power from the spinning disk by attaching one end of the electromagnet’s wire to the outside of the disk and the other end of the wire to the metal rod running through the center of the disk.

Elsasser then points out that an ordinary disk-based “Tesla generator” could not maintain a current for very long because the current induced in the disk is so weak that it would soon be dissipated by the resistance of the conductor [the disk].” This conventional arrangement would not be an answer to “how currents could be built up and perpetuated to maintain the earth’s magnetic field.”

He does, though, propose three options in the dynamo model that would explain the earth’s persistent magnetism.
If we had a material that could conduct electricity a thousand times better than copper, the system would indeed yield a self-sustaining current.

We could also make it work by spinning Tesla generator‘s disk very fast… a third way we could make such a dynamo self-sustaining … is to increase the size of the system: theory says that the bigger we make such a dynamo, the better it will function. If we could build a coil-and-disk apparatus of this kind of scale of many miles, we would have no difficulty in making the currents self-sustaining.

Nikola Tesla did not have a material a thousand times more conductive than copper to use in his generator, neither was he able to spin a disk at the ultra-high speeds needed to produce such a current, nor did he plan on using a piece of rotating metal several miles in diameter. The Tesla generator uses what is usually wasted in a generator and turns it into a source of power.

    i wondered cause i saw a tv show about an iranian inventor, who made a generator that can prepare itself’s energy by itself ! it just needed 20-30 sec electrical energy to start and then it can continue without using any energy from outside !

    Generally to using left-over energy concept from Permanent magnet generator by using conventional motor is not good enough. Because the motor itself using high kW with match torque just left the residual energy very little. But the idea that came to  me by using hydraulic motor and hydraulic power pack is very promising. By using hydraulic motor it is possible to turn High Power PMG (generally with high torque) with very high left-over/residual energy for consumption. Lets try to do this…..

    I am working on a few designs for a self sustaining electromagnetic generator and need to no if a stator design or magnet and copper setup would produce more power output with relative surface area. plz contact thru txt if possible 478-357-8145

    This post truly
    made my day. You can’t imagine just how much time I had spent for this
    information! Thanks.

    I am looking for Manufacturer to supply me continuously with Fuelless Magnetic Generator capable of producing a minimum of 6000 watt.

    If youa Manufacturer or know one to refer to, please contact me.

    Thank you much!

    Simple toys… if you guys want everything to run by fueless electricity
    its just a simple toy … the parts just cost …give or take how ever many kwatts you want out of it to run your house and cars off of .

    Well so far it seems from what I have read online that the current “Recognized” Telsa coils and such do not produce their own energy. Instead it is simply a capacitor style amplifier that turns a 220 or so electrical current into a lower amp high voltage charge. In short you have to plug it into an actual power source, “A wall socket for instance or a gas powered generator” the coils then simply amplify the current thus electrical discharges. If I am wrong then someone PLEASE point me to a place that shows how to build one that is self sustaining from atmospheric particles alone.
    As I would like to find a method to recharge simple 12 volt batteries using such a device.

    Tesla was one of my favorite scientists, truly a genius in his time.

  • robert sina

    its easy.
    all you need is a pnp transistor , a zener diode and an electrolitic capacitor.
    im trying to figure out how to produce more power then that needed to keep the generator running.

  • Daniel @ Number Plates

    Cheers. This was just the information I was looking for, I have trawled through google for this.

  • Rob

    Some time ago i down loaded the tesla generator plans and i did’nt think they were all that great. I could’nt read very much of it , it was blury and the photo of the generator was the same. Needless to say i had it refunded. Has anyone ever built a full scale model that puts out some real power? Who has better plans that do not cost $47 and really tell you what is needed and how to do it in plain terms? I will not down load anymore e-books, they are not worth the money. Every e-book i have bought has been refunded, there is just not that much info in them.

  • Tesla did so much yet he is hardly a household name like Edison..
    It’s a shame and a sham that they stole all his papers after his death..
    Where are they and what have they made from them??

  • I agree with Alexander this is a great e book. It provides easy to read solutions and method for creating the much needed energy.

  • Here’s an interesting information product that I found recently that may be related to renewable energy for homes. It is an e-book. The main web site can be found at http://generatorforelectricity.totalh.com

    When I first read the information on the page, I was pretty intrigued. The introduction videos are pretty interesting also. It talks about generating electricity by using a magnetic generator.

  • Car rental Liverpool Airport, I must agree! It must be a wonderful outcome too for families who ancestors began the work all those years ago.

  • It is my great pleasure to visit your website and to enjoy your excellent post here. I like that very much.

  • Often referring to very early developments will produce the results we are looking for today. I am always interested to read how early technology is actually still a work in progress and it just takes another genius to complete total project, albeit, often centuries later.

  • хорошая тема , буду иметь ввиду ! спасибо
