You mean because of e=mc²? That's true but basically unmeasurable. Air batteries do get mesurable heavier.

Switzerland bolted 5,000 solar panels onto a dam wall 8,000 feet up in the freezing Alps. The plant now makes three times more winter power than any farm down in the valleys in c/technology@lemmy.world

But why? We'll make better blades without the extra weight of the solar panels and cheaper panels by just putting them on the ground.

Any extra weight is too much. Plus a 6 oz calculator doesn't usually fly at 300km/h in open weather, you will need some strong (heavy) glass or plastic too protect the panels. Much simpler too just put them on the ground next to the wind turbine.

It would make sense if there's no space left on earth to build new datacenters, but the simple solution to that is just to stop building so many datacenters.
