I wanted point out how such an invention would not work or be inefficient energy wise..... But then I realized tinker tech.
Skydancer isn't a Tinker. I mean, she'd test out as one if she ever went in for official power testing with the PRT because "Tinker" is just a threat category assessment, not an actual definition of how an ability works. As Sky points out to Dragon, she's not a tinker, she's an engineer. :) And totally mundane engineers are completely able to make a device that differs only in size from what Sky just gave away.
 
Yea, dehumidifier is the best example of a smaller device that condenses water fTom air, but well, it's not very energy efficient, at least with our technologies, and it's still sort of dependant on how much humidity is in the air, in dry areas it may have to suck in stupid amounts of air, and no technology I can think of is going to fix that.

Not a dehumidifier. The linked device decomposes waste plant matter using gasification to produce clean drinking water and charcoal.
 
Wonder if the bootstrap database has anything to quickly and energy-cheaply crack water or rocks for hydrogen? I mean, once you've cracked fusion you can just suck up a large portion of the nearest body of water and produce it in bulk, but at the moment we're looking at large energy costs to produce it for fuel cell vehicles, which have held back large-scale adoption for decades. Although there were those promising results lately with gengineering plants to produce it out of nothing but the normal things they require for photosynthesis - apparently it's an older method of producing energy that modern plant's ancestors used to use, and the genes are still there, just waiting to be reactivated. But a mechanical option that is cheaper than modern methods would be good too - after all, you can't guarantee whatever planet your people are stranded on has long-chain hydrocarbons or productive soil in large enough amounts to use hydrogen-producing plants, for all you can make any celestial body's regolith into soil if you've got enough time and feces.

Hell, better battery tech like the tantalisingly close IRL sodium-ion batteries that hold three times the charge per weight of lithium batteries and don't have the crystallisation problems preventing you from charging one from flat to full in thirty seconds or the use of hard-to-extract elements in them that their older cousins do (they use fucking salt instead) would be great, too - to say nothing of the bullshit sci-fi tech that will need the tools built to build the tools to built the tools to build them - we could build sodium-ion batteries now if we could work the kinks out of them. Current batteries are by far the most expensive parts of EVs and they're still cheaper to produce than traditional petrol designs. With batteries you can build out of salt instead of lithium, you could build a car for a tenth of what current designs cost, and they'd run further and charge faster than it takes to fill a tank of petrol.

While climate change on Earth-Bet may have slowed with the collapse of industry and the amount of human casualties, it's still progressing, and getting everyone the hell off burning fossil fuels and onto renewables/fission/fusion for large scale power generation and hydrogen/better battery electric for when you have to use something not connected to the grid would be a wonderful first step, as well as acting to revitalise industry. Also, all that better power generation and storage? Great for powering lasers, railguns, power armour, all sorts of stuff to bring the balance of force back towards large, organised, state-funded organisations, and away from powered criminals and warlords. All of which they probably have designs for now where the only major part they're missing is the power supply along with maybe some materials tech - and hey look at that, a bootstrap database by a society that laughs at modern material limitations.

For example, and just off the top of my head using some of the things I've heard referred to as the biggest challenges for materials scientists at the moment: room-temp superconductors? Sure you don't want anything that can handle more heat? Methods for producing graphene on a large scale without the flaws? How many do you want, and do you want the database on all the uses we figured out for the stuff, too? Large-scale production of monocrystalline iron and other metals? Do you only want the natural crystals they form, each great for a different use, or do you want all the alternate ones we figured out how to make them form, too? Defeating the current heat and size limitations that have us seeing the end of Moore's Law? Well I already gave you the superconductors and the graphene, but if you do this to the graphene, you get a quantum shadow of the graphene that if you interact with it in this way you can get something with all the physical properties of the processor you built in reality, including the graphene's superconductivity, but with none of the physical limitations of it*.

* - yes, despite how bullshit those words all look together that's a real thing. Or at least, the beginnings of what could possibly be a real thing, if we can figure out how to interact with it, and how to produce enough flawless graphene to make processors out of it in the first place.
