Direct Air Capture Is a Public Good for Climate Era

If it isn't clear from the title: this is direct air capture of CO2.

This is begging for some number play! I'm imaging the production of bricks of dry ice and comparing it to regular clay bricks since I'm in a hurry. Is dry ice easier to create than clay bricks?

World brick production is 1,500 billion bricks (source = Google). 2.27 kg per brick, that's 3.4 trillon kgs of brick divided 907kg/ton = 3.5 gigatons of bricks. I wonder how difficult it'd be easy to make a comparable amount of dry ice. Power it with cheap solar/wind power. Maybe the dry ice can be rocketed to Mars or the Moon to begin terraforming an atmosphere?

OK, imagining over, I'll get back to my day job...
