More that the important wear component in a RO system is a membrane that depends on access to sophisticated manufacturing, while plumbing is relatively easy to DIY in the field, and the big innovation in this system is 2.5mm perforated polyurethane which can also be remade with simple tools (and access to polyurethane of course but that's simpler to make or salvage than RO membranes).
Kind of analogous to ICE vs electric cars; electric cars are simpler in principle but the most important components require access to advanced semiconductor and battery manufacturing, while all the components, in theory, of an ideal "ICE car" can be recreated with early 20th century machine shop technology
- rootusrootus 3y agoA modern electric car is probably comparably difficult to a modern ICEV. If you want to draw a comparison with early 20th century machine shop technology, then compare with an EV of that era. They existed. Lead acid batteries are much simpler than lithiums.
- yencabulator 3y agoI think it's worth remembering that many of the first cars were electric. I'd argue an EV is easier to build than ICE. Neither kind built with primitive tools is going to perform like the modern-day ones. https://en.wikipedia.org/wiki/History_of_the_electric_vehicle https://en.wikipedia.org/wiki/History_of_the_electric_vehicl...
