Finnish City Inaugurates 1 MW/100 MWh Sand Battery

This is super cool but the ending is bizarre.

> A comment on the YouTube video below complained, “Not a word about return on investment in the presentation. That means it’ll never pay off” MAGAlomaniacs are everywhere these days.

Given the supposed 50+ year lifespan of such a battery, I find it hard to believe it doesn't turn a profit at some point. And I understand that debunking low-effort accusations is asymmetric warfare. But why cite a random YouTube comment if you have no intention of addressing its claims? A more charitable interpretation is that it's meant to ragebait the readers. But to me, it seems like trying to make people feel ashamed for having doubts, by making a public example of a skeptic.

Is the comment even that unfair? Asserting that it will never pay off because the presentation avoided mentioning anything about the payoff might be a little bit cynical, but not terribly so. It could be fairly presumed that if the project is a clear economic win, they would be proudly bragging about it; and the opposite presumption is also reasonably fair, even if it turns out to be wrong.

And what does such cynicism have to do with "MAGA"? That asserted association seems much worse than the initial cynical assertion.

All those subjects in the right context are things the left wing fights for. Reducing a complex subject and then saying because you do not agree with my interpretation you are against children, is not optimal. E.g. Climate Activists are a pretty diverse group you will find lots of people who have said the same thing. It is obvious this is a PR/Research stunt, but it might still pay off. This is not a straight forward discussion where all people in the right or left groups has to agree.
