"a technique known as in situ resource utilisation (or ISRU)."
Isn't that just a fancy official-looking term (it's got an acronym, FGS) for "making the best of what you've got"? Or even "if life hands you lemons, drink their juice, then go make some smelly mud pies to build your house."
"the use of a protein called human serum albumin (HSA), which is present in blood plasma, "
Eh, unless this is super-magical stuff where just a drop will make a thousand bricks, won't it take a LOT of HSA to make enough bricks to build structures? I mean, if this is the main binder in a Martian brick, seems like it will take quite a bit of plasma to extract enough HSA to make a single brick. Or maybe Musk is planning to send settlers to Mars by the millions within the first year, so there will be a large and steady supply of HSA. I guess the settlers' bodies won't need it, right?
Here's a chance to make a bajillion dollars - start a concrete company that uses piss instead of water. If it makes the concrete stronger, we should switch-over to it here on Earth, and leave behind this puny concrete the Romans left us, right?
