Now: I guess that ( in that case) my memory is right. I could
not had imagined such thing.
The question remains: is this information accurate?
If yes, this first Testatika should had only used conventional materials and should had been built with usual tools that would had been availiable in a prison workshop. No crystals or other radioactive stuffs that seem not ordinary avaliable in a jail. :))... But, who knows???...
It is a well known fact that if you separate the two plates (by increasing the gap for example) of a previously charged capacitor you proportionaly increase the energy stored in the said capacitor.
Area of the plates: 1 m2
Air gap between the plates : 8.84 mm
Condenser capacity : 10-3 microFarad (1 nano)
Let the voltage between the plates be : Uinit = 3000 Volts.
The intial energy (IE) stored in the condenser is: 4.5 miliJoules
If we, by any mean, increase the gap between the plate by 10.
New condenser capacity 10-4 microfarad (100 pico).
The new capacity is divided by 10 and the new voltage (Uend) become : 30 000 Volts
Q = C*V ----> V= Q/C (Q is conserved).
The new energy (NE) is : 45 miliJoules.
The energy has been mutiplied by 10. What a miracle!
Not at all! Say (official) Science because you had to use some energy (NE-IE) to separate the condenser plates Actually, these plates are stuck by electrostatic forces. Indeed, I was able to do some simple maths considering the most obvious case (perpendicular pull (see further)). I figured out that (official) Science was right (once again ).... So, no miracle. No 'free lunch'. No 'OU'. Move on. Nothing to see...
When two (strong) magnets are stuck together, or one single magnet is stuck to the fridge, which kind of 'pull' do you (or any child!) use to separate them? The perpendicular pull or the 'shearing/tangential' one? (see picture). Sorry for my English. Hope this is not too 'gobbledygooky'!
IMHO, the only question is: is the 'shearing/tangential' way more efficient that the perpendicular one? Jean Louis Naudin seems to have some hints about this question: http://jnaudin.free.fr/html/2magpup.htm
Now, I guess that some Tensor calculus could be of any help. Sorry guys,
as Vector calculus is already over my few neurons, do not rely on me about
this kinda strange calculations. :((
In that case, the lowering of the capacity is not acheived by gap increasing but by face-to-face plates areas diminishing using the shearing/tangential pull.
Yes, you still need some energy to lower
this capacity .
But what if this energy were less that the gained energy doing it?
Now, perhaps, I'm kidding myself
