Reply to comment by gerkletoss in UIUC Researchers propose a new way to get fresh water from seawater, without the disadvantages of traditional desalination. They say that a vertical “capture surface” that is 210 m wide and 100 m tall, could extract enough vapor floating above warm oceans to supply 500,000 people with freshwater by lughnasadh
Salt has a boiling point of nearly 1500C so it is only going to be present in air as an aerosol which again would be trivial to filter out. A coffee filter could probably get the majority of it.

Fog is an aerosol, not vapor. Therefor it could easily be filtered out.

Reply to Getting home off oil. Installed heat pumps. Hydraunic retrofit backup question. by simplafyer
Using a heat pump water heater to heat your home with a hydronic system is like trying to cool your home by opening the refrigerator door. A heat pump water heater pulls heat from the surrounding air to heat the water. Then you try to use that hot water to heat that same surrounding air you just pulled the heat from…
Heat pump water heaters don’t make sense in cold climates as they are pulling heat from air that you then have to heat via other means. Stick to gas/oil for supplemental heat or if electricity isn’t that expensive and it doesn’t get too cold you can just use a resistive heater. But that is typically much more expensive than gas/oil.
