The dream of man to build a car that can fly using as a source of energy the gravitational field of Earth using a small amount of energy it might
I guess for this we should reinvent ourselves.
But a vehicle of this type is possible to be builded With low costs.
The secret is the Cathodic Power.
We ask ourselves many times what could the be use of the crystals in Atlantis by the ancients to fly and to produce energy at very low costs.
I guess the answer is the Cathodic current.
The p-n junction works usually in a crystal made semiconductor.
The n type semiconductor ,the negative charge of electrons and p type semiconductor that contains the positive charge carriers.
When the n type and p type are attached together, a momentary flow of electrons occur from n to p side resulting in a third region where no charge
carriers are present.
It is called the "Depletion region" due to the absence of charge carriers.
I guess the secret for the cathodic engine to work is the "Depletion region".
When a mobile electron recombines with a hole, both hole and electron vanish, leaving behind an immobile positively charged donor on the N side and
negatively charged acceptor on the P side.
Biasing the P negatively charged receptor we can obtain enough amount of correspondent negatively charged dopant.
Let's call it the donor and the acceptor dopants.
The ideal diode ecuation I=Is[e^pVd/(nVT)-1]
The region around the p–n junction becomes depleted of charge carriers and is acting as an insulator.
However, the width of the depletion region cannot grow without limit,only if the P receptor will receive an enough reverse saturation current and
only if ∇T→0
For each electron–hole pair that recombines, a positively charged dopant ion is left behind in the N-doped region, and a negatively charged dopant
ion is left behind in the P-doped region.
As recombination proceeds more ions are created, an increasing electric field develops through the depletion zone that acts to slow and then finally
so the thermal recombination–generation (R–G) also must → 0
At this point, there is a built in potential across the depletion zone and if all the conditions are met We have a gravitational cathodic Engine .
