Silicon nanowires make finer batteries

[alitalf]

I only recently found this report about a means to increase the capacity of lithium cells. It could be useful for many things. Netbooks and telephones are the obvious candidates, but it might also make electric cars genuinely practical.

If the use of renewable energy is to be substantially increased, will require a lot of energy storage, the doing of which is not currently known, if frequent power cuts are to be avoided, and this may be part of the solution.
