Futurology round-up

In our power hungry world, whether you are using a mobile phone, MP3 player (aren't these the same thing now?), cordless drill or electric/hybrid car, we all want more power from our batteries. Now the answer seems close at hand, thanks to nanotechnology.

Looking forward to an era of flexible electronics with stretchy silicon than can be worn on people, planes, walls...looks like another nanotech breakthrough but be warned, there are risks and they ain't pretty!
