Incredible progress on a concept that has been seeking investment for last 15 years. It doesn't just provide 1.2mw, it also operates at a higher capacity factor than capturing winds closer to ground. I'm sure it can scale even higher.
This is useful for clean energy shipping. Design supports an unthethered airship that produces H2 and transports it at the same time. I believe the design would support forward momentum directly upwind, but some tacking angle would be supported.
This is not just a breakthrough in wind energy generation, it is a breakthrough in airship capability.
...produces H2?
electrolysis of water (partially from starting water reservoir, and partially from air humidity = dehumidifier step), can displace water weight with increased H2 pressure in airship. Can put an infinite amount of these over ocean with no land lease costs, but moving giant ships solves the issue of thethering them.
