I eagerly await independent verification!
If this breakthrough is all it claims to be it is wonderful indeed. I really hope it turns out to be true.
One of the challenges in shrinking electronics is that some parts, like capacitors, stubbornly resist being minaturised. The charge-carrying capacity of a conventional capacitor is, after all, partly a function of the surface area of its plates. Graphene is known to have properties that make it attractive as a “supercapacitor …
GO is basically graphite with an oxygen atom added every n molecules.
Think semiconductor doping here, in this case it becomes more conductive in one plane a bit like when you add indium to tin oxide.
I did read somewhere that GO could be considered an N type material where graphene would be P type.
This means that it could be laser printed solar cells next.

"Super capacitor" is a perfectly ordinary term. I've also seen "ultra capacitor" and "hyper capacitor". Top-end supercaps run in the tens of farad range. From the quick demo showing it hooked directly to a LED and running it for 10 minutes, I plugged some numbers into a capacitor discharge calculator, and it would be about a farad at 3.5 volts. At the size shown, that's not bad at all!
Using a dvd burner to manufacture them is insanely cool. If this all works out, and it sure looks like it should if it's on the level, this is a pretty huge deal.
I'm wondering if the disk spins while it's being written?
I suspect at least part of the "supercapacitiance" is the fact the layer is 1 atom thick and so could be stacked to give a high capacitance level on that basis.
Thumbs up not so much for the technique as the implementation on hardware that does not need a vacuum chamber and a couple of $m to buy.
i've got one of these dvd writers. seemed like such an awesome idea - burn a disc, and at the same time, burn the label to tell you what's on it!
sadly, the reality wasn't as good as i'd imagined it would be, and while the labels were readable, you mostly had to be in the right light holding it at the right angle. so i think i only used the Lightscribe part perhaps 3 times, it's been used as a regular dvd drive ever since.
but now! now at least i can feel that it wasn't completely wasted money! now i have something useful. if i can just get someone to employ me to make them supercapacitors....
