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.

A big context costs a lot more

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.
