What's the Latest Development?

What have been the disruptive innovations in the cleantech space? Here’s Kerry-Ann Adamson's list: 3D printing, energy harvesting, energy storage, fuel cell technology, and smart meters. She says they are all innovations that will enable large-scale, fundamental change. 

What's the Big Idea?

Energy harvesting is the process of scavenging small amounts of power from a variety of sources, including collecting the energy in our bodies, and in our movement. Adamson says even just offsetting a fraction of our use of fossil fuels via this method would be significant. Meanwhile, smart meters are already having an impact in educating householders about their energy use.
