I never really got a charge out of going to work, but this could change that.
Don’t pee on the wall........................
If the metal in the anode and the cathode needs to be replaced because the lye in cement causes it to degrade over time, does the whole cement structure need to be replaced?
Most of the metallic batteries are quite toxic in manufacture and disposal. This seem much less so. I’d like to see what the PCA says about this as concrete has a very well understood chemistry.
This probably ends in everyone inside being electrocuted with no way out. Be careful
I was thinking that a lightning strike would be very bad.
I’m thinking someone drilling into the wall for a picture might hit the rebar and become instant ash.
Well, that’s one way to keep from refunding the Damage Deposit.............
It would be so awesome if you could basically make the anode and cathode be the rebar. Then your construction method would be almost identical to a regular building, with some additional wiring.
I don’t know if lye is still active (if that’s the right word) after the concrete sets. And this article says concrete has a high pH that resists corrosion.

Cement is a sustainable building product?
Yes it is. It can be recycled, reused, repurposed and remade..................
A movie that surprised me. I liked it.
Nickel, carbon, cement and iron...Sustainable?
It’s only at the end of the article that we see confirmation that this is actually a battery, with an electrolyte, an anode and a cathode.
Since it’s a battery we need to ask if the electrolyte will ever need replacing. It would be horribly expensive to tear down parts of a building to replace the electrolyte, or even a cell that isn’t working. The assumption here seems to be that this battery will never need maintenance or replacement.
What happens if you touch one of the charged parts, an anode or a cathode?
Will there be signs warning that when the building is eventually torn down, long in the future, that the concrete carries an electrical charge and to be careful not to get jolted?
I wonder if this is one of those research projects concocted to extract that wonderful grant money from the government and destined to be scrapped at the end with the final verdict something like “The concept has validity, and we had a lot of success in this project, but it was determined to not be justifiable economically.”
Oh, and lightning strikes to the building need to be taken into consideration. Not mentioned in the article.
Lightning strikes can be shunted to ground..................
The demand for carbon fiber will soar and so will the price which will affect the cost of carbon fiber consumer products.
Lots of each in huge supply.................
