I mean, its not clear you want to build a house out of concrete walls that aren’t entirely, well, concrete. Even so, its a neat idea, but coming out of the MIT press mill, I’ll not be holding my breath for it to become real. MIT is basically a meme at this point with regards to press releases that don’t manifest into reality.
I wonder if the foundation of the house would be convenient for this… that much concrete is equivalent to a cube of side length around 10 feet, which seems to at least be in the ballpark for the total amount of concrete in a foundation. I think?
For a basement with a 5-inch slab and exterior walls are 8 inches, 8ft high and also concrete… Then 45 cubic meters is about what you’d need.
Of course, your basement walls are about as electrically grounded as it gets, so I doubt you’d be able to store power in them. One leak and you’re discharging all that power into the groundwater.
naturally it depends on the walls and house layout, but just to have an idea: assuming a concrete thickness of 20cm and 4 external walls of 20m x 3m each:
0.2 * 4 * 20 * 3 = 48m^3
probably in the 100-200m^3 ballpark if we count internal walls, which are thinner, but cover more total length.
And I know walls are usually not pure concrete, but functions like energy storage could very well change how we build them.
10kWh is enough to run a house for a day, how much concrete would be in a house with concrete walls?

So, feasible amount. Just needs isolating and could replace expensive batteries for solar?
