Yep. Cazapitors were invented in 1745 by Pieter Van Musschenbroeck of
the University of Leyden. The fun thing to do back then was have 700
monks from the convent of Paris hold hands and watch them

was not only prove the lightning was electrical, but that the charge
resided in the glass of the Leyden jar, and not in the water as

Methinks the problem might be that instead of cazapitors being
infantile, freerguy might be suffering from the same affliction.

Well, if caps are continuously seeing progress in terms of
energy density, what would you say the limit is?

I think what Frank needs to know, assuming he would believe it,
and I'm curious myself, is the absolute theoretical upper limit
to energy density in the dielectric of a capacitor.

Any idea what it is?

I grant that that is all true - because you said so.

But, then I go back to the math.

The energy density math allows for eer. That is, the math does not exclude the
possibitlty of eer.

I suppose that when caps were invented, the scarcity of renewable energy
sources prohibited any effort to match the two.

I suggest that it is different now.

Well, that pretty much puts THAT to rest, then (yeah, SURE
it will). You ARE wrong about that, so you're wrong about
eer. It's that simple.

Note that Frank has yet to point out just where these "errors"
come in. It's "not the math - but the conclusions drawn
from the math." Which is sort of like saying the numbers are
right, but I just don't like those numbers.

Frank cannot show, and does not understand, the "energy
density math" he refers to in the first place, so his opinions
on this whole matter are suspect, at least. And so he most
certainly has NOT "helped here a little."

The "energy density math," though, is actually very, very simple.

The energy stored in ANY capacitor is 0.5CV^2 - which says
that energy goes up directly with the capacitance, but with the
square of the voltage.

For ANY dielectric, the amount of voltage that a capacitor will
withstand before failing is directly related to the thickness of the
dielectric.

Also in any capacitor, the capacitance goes up linearly with the
plate area.

Now, take any given volume. No matter how you arrange things,
additional plate area MUST come at the expense of a reduce
dielectric thickness. You only have so much volume to play in,
after all. So if I double the plate area, but cut the dielectric
thickness in half, I have doubled the capacitance and cut the
maximum voltage in half. Energy density goes DOWN.

This says that energy density will primarily be limited by the
characteristics of the dielectric - both its dielectric constant and
its breakdown voltage. Getting into the physics of dielectrics
is probably beyond the scope of this discussion, and is clearly
beyond Frank, by his own admission. But it comes down to the
fact that for Frank's ideas to be in the least bit practical, he needs
a dielectric that is unreasonably high on both counts. "Unreasonably
high" in this case really means "impossible" in any practical sense.

A lump of coal does NOT actually "contain" the energy
we speak of in discussing the "energy density" of fuels, which

which assumes a supply of oxidizer, which in this case comes

For that matter, "capacitance" is not energy, any more than
the capacity of a bucket - that might hold gasoline, but it might
also hold water - is the energy that bucket might "contain."

You simply DO NOT understand even the most basic points

Energy density should be constant for a given dielectric.
In a given volume, if you double the plate area and reduce
the plate separation by 50% then you have twice the capacitance
at half the voltage, but the same total energy in either case.

Using unity numbers (1 farad, 1 volt) we get
j=1/2(ce^2) = 1/2 joule
Now double the capacitance and half the voltage
and we get the same thing.
j= 1/2 (2*0.5^2) = 1/2 joule.

This means energy is *constant* for any given capacitor
size of the same dielectric. This is a major point that
Frank doesn't get. It proves that etching the plates and
"monumentally" increasing plate surface area does absolutely
nothing to increase energy in a given volume. But of course
a given volume does not include Frank's "innerspace" where
there exists monumentally more volume inside the original
volume. Thus, a gallon is not really a gallon but much more

BINGO!!!!!

The math shows a relative number, which is low, low, low.

The conclusion drawn was that it stuck there - limited.

My deal is that this was an incorrect conclusion - that the energy density of
caps could, indeed, go as high as coal or oil.


Given known dielectrics, it's low. His premise is that there are other
dielectrics which will change that, and it fuels the continuing discussion.
Whether it is better dielectrics, or whatever, it is my position that caps have
the ability to hold much more energy than expected.

Enough, in fact, so that a bank of caps could power an EV.

You're right - I left out a bit. IF you could double the
plate area and reduce the plate separation by exactly
half, then you do get exactly the same total energy. But
that's the ideal limiting case; in practice, since you can't have
zero-thickness plates, doubling the plate area must also involve
a slight but non-zero reduction in the volume that remains for
the dielectric - so you will suffer a loss of energy capacity,
and therefore energy density.
