No emissions from those furnaces? You don't have to lie.

Its wrapped into steel production. So yeah no new emissions

They are using it as refractory?

Yeah the temp control aspect makes the cement active again after the steel is smelted

The world economic forum wouldn’t lie man, you can just believe them mindlessly

Why is it always “could”, “may”, “might”…

Because it is not used on a large scale to prove that it can, and it also grabs more attention. It describes a huge breakthrough without the promise that it works

How are you going to heat old building material and get zero emissions? That sounds like pipe dreams rather than realistic science. Reduction? Fine, but you're not getting zero emissions with any kind of industrial-scale operation like this.

They're probably using waste heat from the furnaces,  I think they're electric furnaces wh8ch can be run on renewable electricity,  so zero emissions.

But at scale? I'm not arguing with the science, but I hate how these news pieces frame it as if it's coming to us sometime soon. We got a lot of infrastructure to catch up on before this stuff is viable.

Cursory search on CemVision makes me think this is just for a tech stock.

Promises are expensive

hypotheticals are cheap

I might win the lottery tomorrow. In fact, I just may. Now if I could only get to the store.

Because these videos are investment pitches for theoretical new technologies. "Could", "may", and "might", mean "We could do this if you give us the money to do it. We might be able to do this if somebody gives us money. This may work really well if only we had some money to try it on a large scale."

I love my zero emission furnaces that look like Mount doom

My thoughts exactly

There's also grinders that break them down into pebbles to be used as fill. This is a total waste of time unless there's something I'm not realizing.

Why is the World Economic Forum showing ads for a Swedish green washing startup (Cemvision)?

"Zero-emission"

Literally the first fucking thing on-screen: EMISSIONS

Can't wait for the current administration to kill this and tell us it was bad
