Reply to comment by hilburn in Potatoes are better than human blood for making space concrete bricks, scientists say by _GreenMartian

I'm struggling a bit to think how there would be enough blood as human liquid waste to be considered for making space bricks.

My memory of the original study was looking at it pretty watered down so you could get a reasonable-ish number of bricks per point, but also that it was a bit of a "well they made bricks with animal blood in the past, so let's see what kinda of properties they have" kind of study.

I guess in the event of an astronaut dying they could harvest the blood to make a porch or something though
