Scientists in the U.S. and China have fashioned the ultimate in power dressing: a fabric that recovers energy from movement and at the same time turns sunlight into electricity.

It may be a while before the new material reaches the high street stores and delivers significant energy savings, but it means that a smartphone in a pocket could charge itself from the fabric around it.
And it stands as yet another example of the burst of global ingenuity by materials scientists and engineers in response to the spectrum of climate change driven by rising greenhouse gas emissions.
Researchers have already tested a "bionic leaf" that can harvest sunlight energy 10 times more efficiently than chlorophyll-powered foliage.
