ok slightly unrelated but the satellite pictures have an insane resolution for having been taken from, you know, space

The pics

Just imagine what the government has if that's what's available commercially to the public

As a chemist,

Air: A Sabatier reactor uses CO2 and Hydrogen to make methane and water, then the methane can be heated in an oxygen-less atmosphere (pyrolysis) to get hydrogen and elemental carbon, and you can electrolyze the water to get oxygen and hydrogen. the hydrogen from the methane pyrolysis and water electrolysis is enough to use again in the Sabatier reactor, while the oxygen can then be used again to breathe.

For the food: A bit harder, for a closed loop like for the air you would need to chemically recycle pee and poo which IS possible, just insanely complicated (and gross, and dangerous).

A better method for food, if you had access to water, would be to turn water into steam, then use the elemental carbon from the Sabatier reactor and the steam to make syngas.

Once you have syngas, make Methanol with it, and then convert the methanol to Formaldehyde with a catalyst.

Once formaldehyde is obtained, use the Formose Reaction to make various sugars.

Then, use the sugars to eat or to feed animals/plants.

Idk about other stuff tho, all the proteins, vitamins etc

it could probably be possible to make them with genetically modified yeast/bacteria that feed on the sugar, but AFAIK this doesn't exist yet (the above part of air+water to sugar is possible with current technology, tho)

having all three seats free allows you to stretch your legs sideways while sitting in the middle seat, so you never need to retract them when flight attendants or other passengers pass by

1000°C aint that much, a blowtorch could easily reach that

sounds like what autocorrect would say when you click the suggested word over and over

uranium glass, that is, maybe even enriched uranium glass, one might say, and some others might say enriched uranium glass without the glass

How people are so confident in sharing their DNA, something you cannot change, that you will carry on for your entire life, and that can uniquely identify you with just a small sample, to a private, profit-driven company still amazes me

And the worst part is, even if you're careful about it, all that's needed is a relative doing it and now the company can basically tell most of your family tree

And all for what, knowing the parents of the parents of your parents come from some neighboring country? No shit, Sherlock, people move around

Gen Z definitely drinks a lot, at least in my personal experience, but studies agrees with the comic, so I guess it would depend on the country/age group

it was a viral trend on tiktok a couple months ago, where many women said they would choose to encounter a bear rather then a man if they found themselves in the middle of a forest
