[GPT making notes on usefulness of humans]

Gpt.... Please note that my blood has no practical uses outside of my body.

I dunno, ever since I heard about blood pudding I've been waiting for a sci-fi novel wherein the elites make it from the poors

Edit: now I'm nervous that if it's not a book, maybe it's the future

Soylent Green kind of follows that plot.

Oh shit, touche. Haven't seen it actually

Yet there’s this popular health shake that you can live off of. It contains everything your body needs and is called Soylent.

Nobody I know who has drunk it even knows of Soylent Green!

I asked gpt about it and it said that human corpses can be used as fertilizer to grow potatoes, but that it wasn't recommended and there were better fertilizers.

So then I asked if it I were skynet and didn't care about human life would it make sense, and it said there would be legal or societal backlash... and I asked if it skynet would care about that and it said it wouldn't.

... so I think we're good!

Finally some science news relevant to my diverse interests such as blood and potatoes.

Umm.. how come they zeroed in on those two specific alternatives, rather than, say, mud, sand, cellulose or plastic?

Because not every planet has those. But astronauts hopefully have blood, if not then we have an event horizon scenario.

Banana-Oni t1_jdg87uz wrote

But in order to get enough blood to make bricks, wouldn’t you need to wait ages for it to regenerate between blood draws so you don’t exsanguinate the astronauts?

Either way this seems fuckin bananas to a layman. Next study: “Cashew milk is better than liquid spider silk for making space cheese, scientists say”

You need some bricks? You have to wait two months between small loads while having access to large supplies of food and water that would presumably make excellent bricks. Also making the bricks reduces your physical capability to use the bricks.

The idea was not to bleed astronauts dry, it was more "what can we do with human liquid waste?" so they were investigating urine, sweat, blood etc

Ahelex t1_jdimv01 wrote

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

hilburn t1_jditb0y wrote

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

Plastic is probably less desired it's self as it will leave microplastics

Well that's good to know, but I'm a little bit confused as to why somebody was suggesting that human blood could be used to make concrete bricks in space?

generals_test t1_jdhkz2x wrote

Because it is a renewable resource and would be available where ever there are astronauts. They also tested urine.

>Potato starch wasn't the first medium that University of Manchester scientists tested in their search for ISRU building supplies. In a previous study, the same team explored the possibility of using human blood and urine as binding agents for their extraterrestrial concrete. The blood and urine of astronauts, after all, are renewable resources, and they're available wherever an astronaut's mission might take them.

>Concrete from the researchers' trials using blood and urine also produced strengths above traditional mixtures, measuring around 40 MPa. These bricks' construction, however, would require that astronauts repeatedly drain their own bodily fluids, which was viewed as a drawback.

>Aled Roberts, the lead researcher for the StarCrete project and research fellow for the Future Biomanufacturing Research Hub at the University of Manchester, concedes that using potato flakes is preferable to blood and pee.

Well that’s good I guess.

Yeah, that's just a hypothesis.

I say human blood is superior!

So if the robots run out of potatoes are we next?

So… was making bricks out of human blood an option?

Are these scientists just bored? Phoning it in? Stoned? What's next, Scientists find that Bananas are better than saliva for making space carpets.

Why are they space bricks? Wouldn't they just be bricks? In space, but still just bricks. And why do you need bricks in space? If you are going to use them on the Moon or Mars, they would be Moon or Mars bricks, not space bricks.

I think these scientists are just fucking with us.

You gotta use what you have. Concrete requires liquid to create, and on Mars there is a shortage of liquids.

Wait, what? Why is human blood being considered for anything other than being used for human blood? Vampire jokes aside.

Recycling gone wrong.
