“This is not that special. Most existing supercapacitors and batteries use cellulose paper as a separator between the electrodes”

Oh, Mr. Magoo. None are so blind, as those that will not see.

This process is using the high surface area of paper as the substrate for the nanostructures.

Would it be better if we could grow the nanofibers into mile-long threads, wad them up and stuff them in a box?

Maybe. But this approach works NOW, and it’s recyclable.

When the cells finally tank, return the cells, burn the paper and reclaim the silver from the ashes.

Thomas,

Many years ago a big company heard about a computer the size of a book with a flat screen with millions of colors.
They said “Its impossible, computers are only 8 bit machines” and threw the person out. That big company was IBM.
So, never say it can’t be done or its pie in the sky as far as technology.

This is not that special. Most existing supercapacitors and batteries use cellulose paper as a separator between the electrodes, they’re just printed separately on aluminum current collectors instead (this makes them have higher conductivity). University professors always claim the world for minor changes to things that industry has been doing for years.

Some critical details are missing – How much energy was stored, what was the size of the cell, how much nano material was used, cost? methods of making, testing?

Thomas Finger rightly wants a here-and now solution. This is one I devised, built and tested that is meant for rural areas of developing countries.

That is really interesting. While it seems more geared to specialized technical use, it would be cool to see bendable paper batteries hit the personal market.

It seems that about 9 of 10 ideas I read from this website are pie in the sky ideas for alternative energies–does anyone else think we need more practical forms of energy–things that could be implemented by maybe 50% of the population now or at least within 3 yrs–I have yet to see a solid list of those ideas/inventions….

This looks very interesting if it could be made economically viable, energy storage in or on any solid surface, built in or applied to houses, cars etc.
