The argument being a US-owned social media application, which still does all of these things, is better than one belonging to an alien company by sheer virtue of the sole fact that it's American?

Sounds like 19th Century American foreign policy.

Besides, there are US alternatives already. YouTube shorts, Instagram reels, no one is flocking to those outlets now even though they are, surprise, functionally identical. The free market the US has cultivated has chosen, and it's chosen TikTok.

>And yeah - it still won't be carbon neutral, but a significant reduction in a very carbon intensive process is still better than not doing it.

In the absence of superior alternatives which should always be pursued first in order of efficiency.

>Pulling it from the air does seem incredibly inefficient when the concentrations will be much higher in the exhaust and waste gasses than the atmosphere. This is where I think the journalistic error occurs. The article says they'll use the AirCapture technology - but I suspect they'll use that technology within a closed system - not just pulling it from the nearby atmosphere.

And it is incredibly inefficient but as marketing it works - the comments here are proof of it.

I meant overestimate how much carbon it removes and underestimate how much it costs to remove carbon from the air.

And its not a new technology that can be improved with iteration - CO2 always takes energy to remove and its other ingredients always take energy to create.

Until we get essentially carbon free and cheap energy there's no excuse to waste it on low carbon concrete when we can use those resources more efficiently elsewhere.

If you're going to waste energy on physically removin CO2 from the air then you're best bet is giving China and India free solar panels rather than using solar panels to remove CO2 to put in concrete

Reply to comment by bluejackmovedagain in Bravery medals for women who raced into 'rough, crazy' surf to save drowning girls by Sariel007

We had that last summer in a nearby lake. A young teen was drowning, 2 different friends tried to help, in the end all 3 teenagers drowned. I think the oldest one was only 15. I get numb to all the horrible news, but that made me feel sick to my stomach for days.

Also, lifejackets are super sexy everybody, I promise. Please wear your lifejacket.
