Gold Digging is back! On this occasion, rather than digging in, we are looking up, and talking to the man who mines Diamonds from the Sky - Dale Vince, founder of Skydiamond. From living as a nomad, to selling phone calls powered by the wind at Glastonbury, to now creating the world’s first carbon negative Diamond; we find out about Dale’s journey to date, and all of the other sustainable (and vegan) pies he’s got his fingers in.
