(Bloomberg) -- Earth’s electricity needs could be met 11 times over if we filled our oceans with wind turbines. The problem is they’re too expensive to build in deep water. Could floating technology change that?

On this episode of The Spark, we speak with Henrik Stiesdal, a Danish inventor and founder of Stiesdal A/S. Referred to in some circles as the “godfather of wind,” he’s come out of retirement to help lead the way in building a potentially game-changing wind turbine.
