supposed benefit of centralized boiling of water - heat captured can be used as power source, probably cheaper to boil in one central location than everybody all over town boils water when they need to drink etc.
- MPSimmons 2y agoVery energy intensive, but probably possible
- ranger_danger 2y agowhat about solar?
- Nevermark 2y agoI am not a fluids, thermo engineer, but maybe: Use a heat pump to boil the water with efficient transferred heat (instead of higher energy generated heat), and some kind of heat recapture from the steam. The heat used to boil the water could largely be extracted from the steam, to increase efficiency, and speed up condensation. If this could be done with a small unit, it would be a nice upgrade over the common end-point on-demand hot water heater. Any temperature water from just under boiling hot, through regular "cold"/room, down to chilled, based on heat recapture level. Always clean.
- bryanrasmussen 2y agosure, but I suppose that 10000 people boiling their own drinking water would maybe be more energy intensive / less efficient. But I can see I got multiple down votes for this supposition already.
- ahahahahah 2y agoThe majority of water is used in ways that none of it would be drank. Even just looking at homes, only about 20% of water in a typical home is used in the faucet (and I expect that's primarily not for drinking). You'd almost need to set up an entirely separate distribution system for it to be more efficient than doing it in the home.
- bryanrasmussen 2y agoOK, pretty good example of my not considering all the inputs to the problem even though I knew all the inputs.
- soperj 2y agoyou'd still need to filter it.
- kwhitefoot 2y agoNow you have very hot water going through pipes not designed for it. I don't know what the consequences would be but I can easily imagine that some might be serious either from an economics or health point of view, possibly both.
- bryanrasmussen 2y agoI was supposing microplastics come into system before they reach centralized location and not in the pipes from centralized location to output in home. But evidently I'm wrong in that supposition?
- kwhitefoot 2y agoI had in mind the effects of hot water on materials not originally designed with it in mind and that the water might dissolve some materials at least slightly but also cause expansion where it was not expected possibly resulting in leaks.
- Two4 2y agoI don't think so (I'd wager too much transmission loss), but pumping heat directly through some other , more efficient transfer medium from a plentiful source (like geothermal energy) might be viable. That heat energy can be directly applied to hot water geysers, central heating, etc etc - basically anywhere you could use a furnace, and some places you can't.
