A solution that is inexpensive, scales, is not inconvenient, and fits household demands? What's the catch?
I hope it's as good as it sounds and becomes a thing.
One of the big catches is how Greenhouse gas intensive concrete production is
I mean, there's a reason why we've taken so long with even electric cars lol I hope this becomes a reality, but moneyed interests will fight tooth and nail.
10kWh is enough to run a house for a day, how much concrete would be in a house with concrete walls?
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?
The catch is, if it works some oil company is gonna buy it out and kill it.
One catch is that carbon black is mostly made from fossil oil.
It's more nuanced than that. The question is whether we're just using carbon black that's already an excess byproduct of other industries, or we'd be actively producing it to make these wall batteries.
The last time this news was posted everyone tore into it. I don't remember the details, but it was funny.
It's just not feasible in reality.
