Sorta like the difference between, say, writing a book on paper vs stone tablets: if it’s a 100 page book, the paper version is compact while the stone tablet version is utterly useless.
Well, not utterly useless.................

In a capacitor, you have two conductive plates separated by a dielectric layer to store an electric field. Graphene makes a plate that has a large surface area in a very thin form factor. You can make a very substantial capacitor that way. Super capacitors are already in use to backup CMOS RAM to save configuration info on modern computer devices.
Probably that it’s ALL surface. Every atom is at the surface. There is practically no thickness, no volume to speak of.
Unlike most structures, where there is a thickness which is a practical waste of space when it’s the surface that matters.
Say the structure shown in #5 above was instead, oh, 3 atoms thick (that’s pretty darned thin) - that would have 1/3rd the surface per volume as this stuff does.

Something that is effectively a two-dimensional plane has a very high surface-to-volume ratio.
Can you imagine the inrush current on a cap that big.
Here, they are working towards drawing electrical energy from static electricity. A few more years and the power grid will be a history.
It could be ameliorated by pulsing the initial charge with low duty cycle pulses then gradually widen the duty cycle as the charge is completed............

You'll need a ladder to charge it.

This was forecast twenty years ago when our educational centers cut back on stressing the importance of mathematics.

Lithium = expensive/rare...
Graphite = cheap/plentiful...
That’s great!
We won’t need coal plants or power plants or nuclear plants since all we will have to do is charge these ....oh.
yeah, but they didn't say a high surface to volume ratio. They didn't say a high capacitance surface. Or a high conductive area. There's lots of things they didn't say but the one thing they did say doesn't make sense.
Supply / demand = determines price................
Tesla's dream, which he dreamt up a hundred years ago. And the U.S. Government seized all his technical papers. I don't know if our Arab overlords will allow this work to continue.
“Reminds me of buckyballs”
We always called this hexamethy-chickenwire.
Wonderful stuff, if it works. I will be impressed when they market a super capacitor with the energy density of Lithium Ion at the same cost.
That will be a significant improvement.
With the advent of the Internet it doesn’t matter if what they want. Free Energy will be a fact of our life and it is being refined more and more everyday. Oil, gas, coal and the current nuclear power plants will be idle within twenty - thirty five years. The electrical power grid will slowly subside from existence as stable alternate energy units are developed and placed.
The mainstream physics community has done more to slow the development of cold fusion than anyone else. They can’t accept that cold fusion doesn’t follow the rulebook they wrote for hot fusion.
I believe that the Never A Straight Answer agency needed to be closed to give the scientific community a chance to reshuffle just who is going to invest technology in outer space. If there is anything out there that’s worth going after believe me independent business men will determine the most cost effective way to retrieve it. It will piss off the current Washington controllers that they aren’t the ones making all the decisions but that’s life.
