  • You can distill the water using solar energy, even without converting it to electricity beforehand, which insanely increases the efficiency. Also, it just requires some initial materials, and then the process basically runs itself. It absolutely could be done at a large scale, especially in places where there is much sun and much saltwater (equatorial coastlines), but the process is veeery slow and there is not enough demand for freshwater (yet) to warrant the construction of gigantic solar stills. As a bonus, global warming increases the efficiency of the process AND the process cools the Earth down somewhat (separating the water and dissolved stuff is a thermodynamically entropy-decreasing process).








  • Afaik dreams get erased because you move and your brain tries to switch to day mode (so that your dream experiences don’t confuse you when you’re awake). The easiest way to write down your dreams precisely is to try and wake up while still laying in bed, and write down your dreams when you’re not as eepy but still in bed.









  • Niche? Are you a lunatic? The 3D printing industry is one of the fastest growing fields in the world. 3D printing is getting cheaper and cheaper compared to eg. CNC machining. The industry is a very important one, because it allows you to create accurate parts much more quickly that to drill a block of metal. And all this not even mentioning that this required mostly general computer science skill, I hope you won’t call the computer science field niche?
