Lego? Everything is awesome

@Diesel Techie It's worth it if you ask me. It lasts for a lifetime, and you can build pretty much anything with it. I learned *so much* about mechanics from playing with that stuff, and it even helped me figure out how pneumatics work. The freedom of putting stuff anywhere you want makes it easy to try things out, and that helps you understand what you are dealing with. Lego is definitely the toy I played with the most when I was a kid - and I'm still inclined to pull it out from time to time. I can't say that about any of my other toys.

If the smashing of CO2 into Gold Foil bends the molecular structure, they could likely be making said CO2 molecules polar in nature, like H2O. If that's the case, then it might be possible to use high electromagnetism or heat (or both) to further the bend magnetically and have a better yield on the O2 production.

As a human biologist and researcher, what I would really love to see is more research conducted in the creation of bacteria which survive these harsh conditions on Mars (maybe if you additionally provide them with nutrients and water under the atmosphere). I know some researchers who are currently trying to completely "build" microorganisms on their own (meaning that they use directed evolution in order to make more and more components of a cell - they are currently working on membrane proteins - would really love to make a video about directed evolution!). Feel free to ask anything about that extreme synthetitc microorganisms (or stem cells, since I am conducting research in this field)!

The low pressure and over abundance of Co2 would be instantly lethal to all known plants, and contrary to popular belief plants do need some O2 to function, a better start might be something like cyanobacteria that produce O2 purely as a byproduct, still need to deal with the pressure among other issues but it's a start

[@Vespuchian]

ALL PRAISE LEGO SPACE! I remain skeptical about long-term Martian surface habitation, much less colonization, until we have a better handle on the lifetime effects of sub-Earth gravity on health. It strikes me that all the problems of living on Mars (entirely worth solving, I must stress), are equally applicable for orbital habitats able to use rotational 'gravity' and thus provide a 'basecamp' facility for Martian surface operations where Mars-nauts can tele-operate rovers and coordinate surface operations from, provide a waystation for traffic between Mars surface and Earth rendezvous flights, and provide medical facilities to help long-duration surface personnel re-acclimatize to Earth gravity. It would also be a great place to retreat to in case a surface station needs to evacuate for whatever reason. I just don't think Mars operations will be much more than Apollo-scale surface jaunts until we have this kind of support capability.

[@havewissmart9602]

I know that space tech always helped us out but i never really felt it. Like it always felt more like scientific curiosity. But this really shows that all tech can be used somewhere completely different! This makes me want to work on this side of space industry

[@robroysyd]

Long ago here on Earth there evolved an organism that turned CO2 into O2. It was so good at it that led to too little CO2 and a quite cold Earth. On top of that it's not just that Mar's atmosphere is mostly CO2 it also has very little nitrogen. There's also not much of any atmosphere and no magnetic field hence radiation is a very serious problem and then there's the one third gravity.

Next up: How Living on Earth Would Make Life Better on Mars

[@fuckgoogle488]

CONCRETE WILL NOT WORK ON MARS: insufficient atmospheric oxygen means that concrete can not cure on Mars, not can it maintain structural integrity.

[@fuckgoogle488]

Oh, and it gets worse. Without atmospheric oxygen, metal does not form a protective layer of oxidation as it would here on Earth. The very moment two non-oxidized pieces of metal touch, they cold weld. This will of course make any machine which involves the wearing of metal on metal surfaces (like bearings) inoperable.

[@deep_fried_analysis]

So basically everything is different on Mars, so we have to come up with new inventions for everything to be able to help with every problem on Earth.

[@korishan]

Concrete actually is recyclable. Problem is it's not as much of a money maker as using new concrete. After crushing concrete and removing the metals, it can be used as the aggregate for fresh concrete or laid down for the bed layer for asphalt.

"Danish carpenter Ole Kirk Christiansen established the name LEGO in 1934 for his manufacturing company, which originally produced stepladders, ironing boards, stools, and wooden toys. The name comes from the Danish phrase "Leg Godt," which means “Play Well” in English and "I Put Together" or "I Assemble" in Latin. LEGO didn’t create the colorful interlocking plastic bricks that the company is known for until 1949."

I believe humans on Mars is a crazy idea, but these ideas are not crazy. Very interesting video.

[@youknowit789]

Why so many less efficient proposals than the Sabatier reaction?

[@youknowit789]

@Mario Perez Oh sure, its awesome. So you take CO2 + 4H2 -> CH4 + 2H2O. So you have tons of CO2 readily available in the environment so the only thing you need to bring with you to Mars to make water and power is Hydrogen :)

[@youknowit789]

@Mario Perez You could even then use the methane to generate power for electrolysis and split the hydrogen and oxygen back up from the water and restart the cycle. There is some energy loss each cycle but with solar panels you can basically swap between natural gas, water, and oxygen as needed :)

[@saintblankie]

Wait the minute, what about producing nitrogen on Mars? I doubt you can just breathe pure oxygen on Mars like the astronauts on International Space Station.

[@lobsterbark]

They don't use pure oxygen in space, it's way too dangerous. Even stuff like polyester clothes and stuff burn extremely easily in pure oxygen. Plus, things degrade from oxidation a lot faster. A high co2 concentration is still bad for humans even if there is plenty of oxygen present, for instance an atmosphere of 25% co2 and 25% oxygen and the rest nitrogen would kill a person pretty quickly. Even a co2 level as low as 0.5% is not something you can live in for more than a few hours to a day, regardless of oxygen percentage. Terraforming Mars to the point of being able to live on the surface with nothing more than an airsupply and some warm clothes is probably the most humanity can realistically ever hope for, and even then that is a huge stretch.
