45-cubic-meter volume of concrete—roughly the amount used in the foundation of a standard home

This is more than 45 tons of bs 🤐

What a dreamer.

Doesn't seem completely impossible with the estimated storage capacity, but like with all of these things, drastically changing the build up of concrete means changing the properties of the very thing used to hold your home together.

It might be cheap materials, but the effort involved also seem very high having to cut up after the hardening to create the super capacitors. Which again may affect structural integrity.
