Shaping Silicon on the Nano-Scale

Shaping silicon on the nano-scale promises a way to make a battery that stores lots of energy and lasts for many charges.

This remind me of the story of Thomas Edison's first long lasting light bulb filament. He took a bit of cotton thread, shaped as he liked and then baked it until all that was left was carbon. If he put a thin carbon wire in a vacuum, he had a reasonably long-lasting light bulb. Ingenuity never grows old.
