As long as the crash rate isnt higher than those of airplanes i think there shouldnt be any complaints. Or are you constantly scared of a plane full of much more dangerous kerosine crashing into your house? And i dont see why it shouldnt be possible to make them as secure as or more than planes. They will surely be inspected regularly just like normal wind turbines so its just not an argument at all i think. Their location being fixed also makes them much less dangerous because you can just put them on mountains where nothing much exists.
















Sadly i didnt see any energy numbers in the article to get a feel for how many kWh this thing stores. Probably not much at all, but still a cute idea i guess.
Dumping thousands of these into the ocean is probably much more economical than building the same amount of 65m tall water towers. Because thats basically all that this is. Would probably be much more resource efficient to go a lot deeper though, like the 600m deep Fraunhofer project they mentioned. As long as it costs less than 10x as much to build its better value.
