Oh yeah?

Pyramids were batteries, according to various people who study these things. You’ve all heard about that, yes?

So many links out there, if anyone is inclined to leave politics behind today and go in search of ancient aliens. Fun stuff for distraction.

both lye and concrete are acid and caustic but lye is not Portland cement.

Rebar is attacked by chemical processes as it ages inside reinforced concrete. That is why bridges are built with epoxy coated rebar. Some electrical charging is sometimes applied to bridge reinforcement to counteract ion transfer.

Another one of these experiments that if were put into actual practice and a building is constructed, what could possibly go wrong?

This probably ends in everyone inside being electrocuted with no way out.

I imagine such a building would be like a Faraday cage. There would be no risk to those inside. However, passing between inside and outside could be risky; doorways would have to be covered with non-conductive materials.

What could possibly go wrong with a huge, multi-story cement building, charged with a zillion volts? Or is it watts?

Cement is a sustainable building product?

That's news to me too. I thought that once concrete sets, its chemical composition has changed. It can't be ground down to make into concrete again.

I liked it also.

Although I noticed that the Freddy character reminded me of the Griffin character in MIB 3. Probably a casting decision but it does seem funny.

It can only be crushed and used as a course aggregate. It will still will need cement and sand to make is into concrete.

I look forward to youtube videos of local zoning board hearings for one of these in a suburban or rural locale. Should be very interesting.

And the tinfoil hat concession would able to profit from all portions of the spectrum as well.

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.”

Most early stage research never advances to a stage where it is commercially viable. This has been my experience in medical research, and I assume the same principle applies in other areas of research.

In the medical world, I've seen some truly astounding technologies that will never reach clinical use. Imagine being able to stop an epileptic seizure by shining a light into the brain. It can be done in lab animals, but I don't think we'll ever see that used in human patients.

The cathode will erode and the anode with build up material. That would be unfortunate.

So you are on the 20th floor and it has a short circuit?

“Imagine an entire twenty-story concrete building that can store energy like a giant battery.”

Imagine “catastrophic discharge”...

good ol’ American ingenuity.

"Results from earlier studies investigating concrete battery technology showed very low performance, so we realised we had to think out of the box, to come up with another way to produce the electrode. This particular idea that we have developed - which is also rechargeable - has never been explored before. Now we have proof of concept at lab scale," explains Emma Zhang, Doctor, formerly of the Department of Architecture and Civil Engineering, Chalmers University of Technology, now Senior Development Scientist at Delta of Sweden "We are convinced this concept makes for a great contribution to allowing future building materials to have additional functions such as renewable energy sources," says Luping Tang, Professor at the Department of Architecture and Civil Engineering, Chalmers University of Technology

if the building is built in Watts, will it survive the next round of BLM protests?

Sleeping in a battery has to be as safe as sleeping on an x-ray machine what could go wrong.
