Original Text


But all of these are mostly invisible to us. The challenge in studying those ocean variables at scale is one of energy, the energy that it takes to deploy sensors into the deep ocean. And of course, many solutions have been tried — from wave-actuated devices to surface drifters to sun-powered electrical drives — each with their own compromises. Our team breakthrough came from an unlikely source — the pursuit of the world speed record in a wind-powered land yacht. It took 10 years of research and development to come up with a novel wing concept that only uses three watts of power to control and yet can propel a vehicle all around the globe with seemingly unlimited autonomy. By adapting this wing concept into a marine vehicle, we had the genesis of an ocean drone.
