It is practical from an engineering standpoint. I am a follower of the late, physics professor Gerry O'Neil, and others who have long, proposed this technology. Having stated this, let us never forget the age we live in, for Christ's sake! (Expression).
I am an enthusiast, for ocean wind power based on a IEA article from October 2019.
This:
IF, we choose to harvest the ocean winds, we have the promise of about 11 times the potential energy produced by our species, during the year 2018. What's the big drawback then? Well, basically Russia and China shutting down ocean platforms with drone submarines. We'll need protection from that attack. Power shutdowns could become chronic with this!
The same with Solar Sats in Geosynchronous orbit. We'll have to make for ourselves drone clean-up craft by the thousands, to clear up the swarms of debris left from an attack from a hostile. All that shit flying about at fast speeds would likely preclude any Space Program by anybody, let alone, power sats! Lights out dirty, Иностранец, laowai!!!
Our age, out of an abundance of caution, precludes doing power sats and maybe ocean wind arrays, because of human perversity, and I ain't talking about sex, either.
