Yeah, boiling milk is is going cut through concrete at about the same rate a river cuts through a continent, and that process isn’t melting

I think, therefore AI

Does milk have to be in liquid state to still be considered milk?

“Milk, when vapourised, passed through an appropriately enegetic field and converted into a plasma, can melt concrete”

Did it specify how hot the milk needed to be?

Arguably you could use pumped hydro with the abandoned mine shaft?

I believe the argument against solid block gravity batteries is that you can achieve the same thing with water by using old mines or even just digging a 40story hole. If you have room for the 40 story tower then you have room for a more efficient pumped hydro hole.

Wasn’t this already debunked as a poor replacement for pumped storage hydro electric? The blocks and the things moving them will always have more wear than water and turbines.
