Will it change the world?

Just amazing! It can make (eventualy) electric car real competitor to fuel burning one. Because for now electric car recharging is the only thing which turns off most of the potencial customers (me included)

That certainly has potential.

People have been talking about "ultracapacitors" for as long as they've been talking about "developments" to batteries and solar panels -- decades. The problem is that we're so far from what's needed to make them viable energy providers that another year or decade or incremental improvements won't cut it.
Batteries are incredibly low density energy stores compared to chemical sources, and capacitors hold a tiny fraction of what batteries do. So even "super capacitors" that fall somewhere between capacitors and batteries are woefully inadequate.
To replace actual engines, you need thousandfold increases, not the marginal steps we've been chasing for decades. There is no miracle revolution around the corner, just a slightly-less-crappy "alternative". The benefit to these will be stretching the legs of your phone or tablet, and maybe letting your laptop run all day. But don't expect to be making trips in a super-capacitor powered car, or getting any kind of reasonable performance.

That certainly has potential. It certainly does... Pun intended?

The real potential is probably in marrying supercapacitors to solar. That combination along with geothermal cooling & heating could be very green and economically feasible. Now if we'd make some nice advances in solar efficiency. I'm curious as to what they used as the electrolyte between the layers of graphene. Got my LightScribe writer right here, now just have to order some graphite oxide.

, had to read the paper. They used Poly(vinyl alcohol)(PVA)-H3PO4 polymer gelled electrolyte.

That's positively amazing.

But don't expect to be making trips in a super-capacitor powered car, or getting any kind of reasonable performance. Performance? Try the Tesla Model S. The Nissan Leaf is a very capable vehicle able to go 80 to 100 miles on a charge and gets about 150 miles on $4 worth of electricity. You can charge it (with the proper charger) in less than 2 hours. Later this year the base model Leaf will be about $20,000USD after tax credit. And, in city driving, it's quite spirited. We're only in the infancy of main-stream electric road going vehicles. Give it another 10 years and see! It takes time and money to build an infrastructure. Unless your comment was solely centered on super capacitors and not electric vehicles in general.

I would not be the happy flap, but If the half of car's owner have electric car, own many energy centrals will we have to construct and what kind of energy will we use? gas, coal, nuclear...?

As with many truly amazing accidental discoveries, this will, too, be refined, put into use, and become the new paradigm. Few will know or even care when it happened, where it came from, or who was involved. I can imagine that there are more than a few already making plans to gear up the R&D departments at various labs.
Even if the scale needed would be daunting, huge storage devices based on this would be cheap to build and could really change the world. It's fun just to think about it.
