    Double edged sword. Reduction in mass but adding the energy to other parts causes safety problems.

      Yes, I agree. But the first step in anything has risks. I'm sure someone will innovate a safe way of energy distribution given time. Hopefully those developing this aren't too stupid to see the negative possibilities of something like this.

      This reminds me of the miniaturization used by Asimov in his Foundation series - an entire ship with its engine build into its thin hull.

        Another one of my favorites. Ever read his biographies? Fascinating.

          No I never read his biographies. But I did read the entire series, Robot and Foundation, twice (years apart). The connection from book 1 to the final book was mind blowing. I have to admit though I wasn't crazy about the choice. :)

            Don't remind me, it's been a while and I was looking to go back to reread.

            His description of a Russian immigrant family in the early 20th century in NYC is fascinating.

              I won't say more. Except that Asimov was a major influence in my writing approach. Whether I pulled it off to credit him or not is yet to be seen. I'm only on book 3 after all. :)

    Super-capacitors have a very small energy density on the average ~.01 Mj/Kg, battery's like lithium ion have around ~0.46-0.72 Mj/Kg it's a pretty big difference. We use super-capacitor based power backups on our routers, lasting just a few minutes, where a LiO Battery would last hours. Maybe someday it will be worthy, just not yet.

    The capacitance of the supercapacitors follows a function of porosity on the nanoscale that I would expect. I haven't looked at this in complete detail, but this looks legit to me. I am adding it to my coursepack for my nanotechnology class. Harvesting energy from vibrations has been a goal for the last decade. This class of materials would be suitable for that. Imagine a wearable device that gets its power just from you walking around.
