The system is a moored deep-sea turbine that hoists a weight up from the sea floor, and when power is needed, it drops the weight which generates power on demand.
He points out:
7:06 although vertical axis wind turbines have slightly lower efficiency, they can operate in a wider range of wind speeds - 10:34 from 8 to 80 mph (vs 30-55mph for traditional horizontal axis turbines.) 8:01 It doesn't have delicate electronics connected to the blades, just a winch - allowing it to hoist the weight across a wider range of windspeeds.
7:25 They can be installed closer to each other because there's less turbulence downstream.
11:04 they can generate 4 times as much energy per area of sea surface.
11:13 power output can match demand without battery storage because they're able to produce energy regardless of the wind speed
