Human blood bricks to be 'exploited' by scientists for building on Mars - New York Post

That’s the impetus behind researchers’ ghoulish new endeavor — to save a buck by engineering building components using human fluids.

They’ve already done it with urine; now, they’re out for blood.

Scientists believe that strengthening proteins in human blood impart biological properties that could make for particularly hardy bricks when mixed with Martian regolith, the dusty substance that covers the dehydrated planet.

“Other in-situ human resources, such as hair and nails (keratin), dead skin cells (collagen), mucus, urine and human [feces] could also be exploited for their material properties on early extraterrestrial colonies,” the team said.

“Unfortunately, due to health and safety concerns, we were unable to explore human [feces]-based [extraterrestrial regolith biocomposites] in this study,” they added.
