    The team worked out that a 45 cubic meter material block of nanocarbon-black-doped concrete would have enough capacity to store about 10kWh of energy, which is reckoned to be the average daily electricity usage for a household, so remote off-grid houses with batteries in the foundations could operate using windmills or solar panels.

    That’s ~1600ft^3 for those of us unfortunate enough to have an innate sense of freedom units and not logical units; a lot of concrete!

    I’m very curious about the longevity and durability of these bricks, and safety considerations. Such a house could potentially, (pun intended,) instantly discharge a lot of electricity into someone who comes in to contact with its foundation. Don’t use that masonry drill, it might kill you!

      Or alternatively, can it even discharge fast enough to provide a meaningful enough amount of electricity?

      What does the charge/ discharge cycle do to the integrity of the concrete?

      What special conditions are necessary for is curing? Whats the yield? Because the consequences of having a 45 cubic meter block of concrete that was supposed to be a battery sitting in my yard but isn’t are not trivial.

      Whats the carbon footprint of adding 45 additional cubic meters of concrete to every structure? It takes a shit ton of energy to rip off the necessary electrons from lime stone to make lime.

        They’re saying it coule be part of the foundation.

        Basically for the average American house I think that would just be a slightly thicker foundation (if it could work like that)
