Innovation = Doing things differently and doing different things
I coined this definition of innovation some time ago. Sometimes it is about technology, sometimes simply about changing opening hours of a shop.
Recently I came across an idea to harness gravity in disused mine shafts to generate and store electricity, with multiple uses, including balancing power to electricity grids.
I liked the idea. Well, liked it so much I invested in Gravitricity through CrowdCube. Oh, and Crowdcube itself is another simple innovation, a way to crowdsource investments in businesses, a simple extension to the crowdfunding concepts innovated by Kickstarter etc.
