Print Page - graphene based superconductor

If you have a large number of very challenging problems that hold you back, why not just solve them all in a single go?

People figured out how to make superconductors (with 10000x the state-of-the-art energy density) scalably, cheaply and environmentally friendly.
It involves zapping graphene oxide with lasers in a similar manner to how DVD burners burn DVDs to create a material with an absolutely insane surface area: A single gram of the material has a surface area of about 2630m². (according to WolframAlpha that comes out to be a relative scale factor of more than $6700$ . For comparison, for a sphere that scale factor would be $\sqrt[3]{6} \ \sqrt[6]{\pi} \ \approx \ 2.2$ and a cube would achieve $\sqrt{6} \ \approx \ 2.45$ .)
Along with a couple other clever innovations, the results are insane. Basically the holy grail of electrical storage has been achieved with capacitors that

have insane energy density
have significantly reduced charge leakage
have a longer livespan
are much cheaper to produce
are much smaller than currently available capacitors
are flexible because of the super thin form factor
are saver for both the environment and household usage
are expected to be Moore's law scalable

And the group also manufactured a proof-of-concept (i.e. very likely much improvable) hybrid capacitor-battery which achieved 10x the energy density of current batteries while also being able to be charged and de-charged much faster as well as being a lot more efficient than normal batteries.
