So let me get this straight:

1. Smear graphite paste on a CD/DVD.
2. Put said disc into laser drive.
3. Take out graphene disk
4. Something magical.
5. Charge it.
6. Use your super capacitor.

That sounds awesome, so, what's the hidden downside that I'm missing?

You have to sharpen your pencil after.

I've stopped getting hopeful when I see things like this because I've seen so very many things like this that haven't amounted to anything. Exciting treatments for disease and cancer, wonderful technologies, concepts etc.

Mebbe I'm just being impatient, I know science can move slowly, but surely some of the things people have raved about in the last 10 years will come to fruition (or at the very least you'll hear about them more than once in some vague video).

Best of luck to em but I'm not holding my breath.

I hate to be "that guy" but is this real?

looks like a concept to me, so fake?

Seems legit (see below link). Apparently works because it's so thin and therefore has such low mass, and yet it's still latticed graphite. It has all the conductive properties of graphite but flattened to 1 atom thick. So we're talking about capacitance per kg (grams in practicality but kg is SI) and when you get a bunch of them arranged into a capacitor, you'd have more capacitance for the mass of your capacitor than with an ordinary one.

(that's straight from the wikipedia reference)

As a side note, if it's sciencey and you can't find any pdf or some sort of publication on the matter then take it with a pinch of salt. Conversely a pdf or publication doesn't make it true

I'll bet the railgun people are all over this.

No no. It's more like:

1: Collect Graphite.
2. ?
3. Profit.

Using graphene to store energy is, I believe, not a new idea in itself. But finding an actual marketable, affordable solution is pretty interesting.

Worse, BP does.

Welp, there's your power source for your flexible e-paper. Figure out how to work photovoltaic panels into the mix and you can charge it while you're reading it.

I envy our youth.

Sift of the week.

I am not sure how you get around nonuniform discharging. But graphene is superinteresting. I could ask an expert if you all want.

excellent

Bring forth this lab coat wearing expert!

I'm probably just as tired of these over-promising advances as other people, but you have to remember that sometimes things don't work (at the scale/cost we require), and it can take a long time to reach that conclusion despite early excitement. We also have to remember that these types of announcements can be a method of soliciting funding.

I'd love to see this type of tech productized, I'll take two please.

While the science behind it is exciting and definitely legit, those presentations really get on my nerves.
They go from overpromising and pretentious ("I thought the world changed at that point") to downright negligent and dangerous ("It's carbon, therefore harmless - you can even compost it!") Yeah, sure. Nanotoxicity, schmanotoxicity...what is this, Duck and Cover?
IMO, "compulsory positive" presentations like these hurt scientific reputation in the long run.
