Electricity like you have never seen it before

[Qwert]

The orbit is like a circle or an arc of a circle. the Force exerted on the electron is always vertical to the direction of its speed, thus the  magnetic field neither adds or takes energy from the subject. the speed u can be analysed in the ux and uy. uy is the extra speed added in every loop, it is excess energy being created. All the added screen is doing to correct and control the end effect of the field on the right of the capacitor.  The end effect of  the capacitor is affecting  velocity U  to a small extend, depending on the vertical position, of the electron, going out of this capacitor, whether it is closer or less closer to the separated positive plate from the negative one. Using the screen this vertical position of the electron  dependency  is eliminated. Provided, the particular electron is not hitting the solid metal grid of the screen by pure chance, and it is not absorbed by or distorted by the solid metal grid of this screen.

What kind of mechanism causes the acceleration?

Well, it must be a total miracle then that CRTs work at all, since their electron beams travel in _straight lines_ due to being accelerated by the _electric field_ between the cathode (at the gun) and the grids and anode (at the display screen), and are curved or deflected into the scan pattern only by the _magnetic fields_ of the deflection coils and adjustment magnets.

Panul, please read this page carefully before you start trying to describe how electrons actually move in magnetic and electric fields.

http://www.schoolphysics.co.uk/age16-19/Atomic%20physics/Electron%20physics/text/Electron_motion_in_electric_and_magnetic_fields/index.html

Charged particles move in parabolas if projected into an electric field in a direction at right angles to the field.
Charged particles move in straight lines and accelerate (or decelerate) if projected into an electric field along the direction of the field.

In a basic triode vacuum tube, the electrons are emitted by the cathode, are accelerated by the electric field potential difference between the cathode and the anode, and are _controlled_ or modulated by what is happening at the grid. The grid absorbs more or less of the accelerated electrons depending on the voltage applied to it and the frequency with which that voltage is varied.

According to: http://panospappas.gr/osc4.htm:

"Cathode and anode are both grounded to zero potential. An electron with kinetic energy received by the heated cathode approaches the neutral anode. There on the anode, by induction, opposite positive charges, are accumulated, which attract and accelerate the electron. The electron passes the new hole again, which a negative concetretic negative ring is placed, as shown. The negative ring repells and farther accelerates the electron to the right towards the next anode. The whole process is repeated, increasing the velocity of the electron, farther and farther,..., making U0, <U1., < U2,< U3."

My question to Panul: can you describe more exactly the mechanism of the anode build-up (of the opposite charges) with induction? As I understand, the build-up gains-on before the stream of electrons reach it; is it possible that induction comes first, before the electrons reach it? And is this build-up strong enough to make potential difference higher and higher on each consecutive stage? Is this build-up influenced by this stream of electrons or it's independent? I'm really confused here.

To be clear:
though this guy does not state this clearly, my understanding is that he claims that mere POLARITY DIFFERENCE, not necessarily POTENTIAL DIFFERENCE is essential to accelerate a stream of electrons in a CRT (Cathode Ray Tube) and thus get Free Energy.
While the normal/original CRT operation relies on quite a lot of energy PROVIDED TO IT and the purpose of CRT was/is quite different and certainly not in the field of saving or producing energy. What does not mean that this kind of device cannot be used otherwise in such a search. http://en.wikipedia.org/wiki/Cathode_ray_tube
