Dale Vince, the founder of green energy supplier Ecotricity, claims to have developed the world’s only diamonds to be made from carbon, water and energy sourced directly from the elements at a “sky mining facility” in Stroud. The “green technology first” uses carbon dioxide captured directly from the atmosphere to form the diamonds – which are chemically identical to diamonds mined from the earth – using wind and solar electricity, with water collected from rainfall. Vince expects his new venture, Sky Diamonds, to produce 200 carats of the carbon-negative diamonds every month but said the facility could scale up to create 1,000 a month within the next year. Vince has promised to source the carbon dioxide directly from the air and will produce the hydrogen needed to make methane by splitting rainwater molecules using a renewable energy powered electrolysis machine.
