    At a claimed energy density of 0.22kWh/m^3 I think their projection of storing enough for an entire household is overly optimistic.

    My whole foundation for a 2 story 200m^2 house is about half the 45m^3 they claim is needed for a household.

    Sounds promising but it won’t be replacing batteries any time soon.
