Towards Realizing the TPU

Hello all,

@FatBird

is seems you should again, or for the first time, read SMs words.

Where can I find a SIMPLE sinusoidal adjustable generator based purely on vacuum tubes ? Something like replacement for 555 circuit but for AC signal

For example has anybody tried to understand the Tesla Magnetometers, which he "tuned" to the magnetic fluctuations?   (again all his comments were made in context, which was, he was trying to prove that yes you can extract energy from the MAGNETIC field of the earth)

Hi EM 

I have found the part which Steven Mark means in Tesla's writings.
Here is the first part by Steven Mark, followed by the part from the writings of Tesla.

Nicola Tesla said that one day in his laboratory he was noticing that there were some reactions on his magnetometer for no reason he could understand. The next day he had many magnetometers brought into his laboratory and he began additional research.

He noticed that most of the time the magnetometers stayed relatively sedate and around the same level. They would fluctuate just slightly. however one day he noticed that the meters jumped quite unpredictably.  It attracted his attention and he began to find that the meters were reacting to a thunderstorm many hundreds of miles away. Interesting isn't it?

Then he continued his experiments and found that as a thunderstorm moved closer the magnetometers would register larger and larger fluctuations until they were off the scale and useless. 

He was fascinated and consumed by this. He acquired better magnetometers and his research found that you could tune the magnetometers to certain specific frequencies and tap directly into large magnetic waves. When I say large, I am referring to huge. That was useable power.

However, you had to find a circuit potential in order for the electrons to flow. That was the difficulty which he overcame to produce his famous demonstrations of power from nowhere.

Here is the part from Tesla, it is in one of his books aswell as in the colorado spring notes.

Discovery of 'Stationary Waves' made July 3, 1899," and recorded in detail:
Observations made last night. They were such as not to be easily forgotten, for more than one reason. First of all a magnificent sight was afforded by the extraordinary display of lightening, no less than 10-12 thousand discharges being witnessed inside of two hours... An instrument (rotating "coherer") was connected to ground and a plate above ground, as in my plan of telegraphy, and a condenser was used to magnify the effects transmitted through the ground... As the storm receded the most interesting and valuable observation was made. It happened this way: the instrument was again adjusted so as to be more sensitive and to respond readily to any discharge which was seen or heard. It did so for a while, when it stopped. It was thought that the lightening was now too far and it may have been about 50 miles away. All of a sudden the instrument began to play, continuously increasing in strength, although the storm was moving away rapidly. After some time, the indications again ceased but half an hour later the instrument began to record again. When it once more ceased the adjustment was rendered more delicate, in fact very considerably so, still the instrument failed to respond, but half an hour or so it again began to play and now the spring was tightened on the relay very much and still it indicated the discharges. By this time the storm had moved away far out of sight. By readjusting the instrument and setting it again so as to be very sensitive, after some time it began to play periodically. The storm was now at a distance of greater than 200 miles at least. Later in the evening repeatedly the instrument played and ceased to play in intervals nearly of half an hour although most of the horizon was clear by that time.

     A rotating bodies electrical charges can be viewed as alway accelerating as they continously enter and leave one plane to the next.  This produces a magnetic field displacement that propogates at 90 degrees to the direction of rotation of the charge field.  As the velocity of the rotating body is lower near the axis of rotation than that at the equator the magnetic field displacement at the axis is many orders smaller than that at the equator.  The magnetic field arising from the rotating electrical field takes on a polar configuration.  The lines of force concentrated near the surface of the rotating electric field at the axis and projecting outward to maximum displacement at the equator.

thanks for that marco,  it seems SM is off a bit.

if Tesla used the "coherer"  than this document explains more about what that device was:
