Harnessing solar and wind energy in one device could power the 'Internet of Things'

The "Internet of Things" could make cities "smarter" by connecting an extensive network of tiny communications devices to make life more efficient. But all these machines will require a lot of energy. Rather than adding to the global reliance on fossil fuels to power the network, researchers say they have a new solution. Their report on a single device that harvests wind and solar energy appears in the journal ACS Nano.
