Before going into the details of this invention it would be worthwhile to have an idea of how any 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 models 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 the 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.
Tesla did not have a material a thousand times more conductive than copper, 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. What he did was to use energy that is usually wasted in a generator and turn it into a source of power.

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.

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

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.

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.
