Mechanical energy is going to become extinct. do you want to hang around an area that is going to be wiped out?

No moving parts!

Jerry, I know what you're talking about, but that is far into the future.
Just think about this, how is an electric saw supposed to cut wood if the it cannot move?
Also what about hydraulic pressing? Point is as long as we need to move things physically we need motors that can do it, be it electrical or not.

Cars for example is one of those things that could eventually go over into solid state, when the technology is there. The only thing moving would then only be the car itself , while everything inside was controlled by some kind of field.


But there is also something else you should be aware of; there exists no real solid state system anywhere! What creates electricity and magnetism? Motion of nano-sized particles.
Spin is the thing    It makes every structure and reaction we know of stable, but it will never be solid state.

Hi Julian.

I was actually referring to making electricity via macro mechanics.

some mechanical schemes seem to be unavoidable like presses and stuff but macro mechanics isn't needed to produce electricity like that used in Hydroelectric dams and the lot.

Jerry

Ah okey. Well they can always be made more durable and stronger. When I think about it, a hydro electric dam would probably be a lot more powerful if it used tesla turbine instead of the normal turbine. Wear and tear should be practically eliminated, efficiency should be better and practically all of the kinetic energy stored in the water should be possible to be converted. But were you maybe talking about something different when you mentioned macro mechanics?

Julian

This principle can be uses as a measure of improvement, without spending a lots of energy!!!

Energy Measuring

It is important to note that we are not supporting over unity claim for the oscillator where its pendulum was initially raised to some height and then left to swing until it stops.

Our idea is that after initial raising of a pendulum it is necessary to keep adding a little energy to a pendulum to keep it swinging. Because two stage oscillator is supposed to be used for long period of the time, energy spent for initial raising can be disregarded. The same logic is for Diesel engines where it is necessary for them to achieve working temperature before measuring its efficiency. Nobody would also include energy spent for magnetization of permanent magnets in an electric motor for calculation of efficiency ratio of his electric motor.

It is necessary to measure small energy continuously added to maintain pendulum swinging. Note also that output force on the lever side is variable and change from zero to a maximum defined by its mass. The reason for it is variable force of the pendulum which exert pulling the lever on opposite side. This makes mathematics complex and precise tools for measuring variable force are necessary for calculation of efficiency ratio of a two stage oscillator.

The well known fact is that pendulum with fixed pivot point can keep swinging for several hours. Two-stage oscillator has movable pivot point. It moves in rhythm of the lever which frequency is double higher than frequency of the pendulum. The movement of the pivot point, or better to say its acceleration, keeps spending energy of the pendulum which decelerates its swinging fast. Friction in pendulum pivot point is very small in comparison with losses due to movement and acceleration of the pivot point and can be disregarded. Oscillators with small and harmonic movement of the pivot point have better performances and that is the reason why special attention should be given to that problem.
