555 kWh is about 55 USD at $0.10/kWh, so for 22.5 m3 that's about $2.5 per m3 (or 1000 l) of water, cheaper than EU residential prices (3 EUR per 1000l in Franc

555 kWh is about 55 USD at $0.10/kWh, so for 22.5 m3 that's about $2.5 per m3 (or 1000 l) of water, cheaper than EU residential prices (3 EUR per 1000l in France) and also than than what I can find about US residential prices (NYC: $10/100 cuft or $3.5/1000l) Cheaper is good, because this is just marginal electricity cost, total cost per 1000l is going to be higher, it will include maintenance and equipment depreciation.
- kwhitefoot 7y agoThey aren't using grid power, they are using solar so you need to consider the capital cost over the lifetime of the system. And remember that my figures assume that you extract all of the water from 100% humidity. But you don't have that and anyway a condenser would work perfectly well if you did.
- bufferoverflow 7y agoThe assumption above is 100% humidity. Which you won't get even close to in a desert near Amman, where it's around 50%, and only because of the ocean proximity. If you look at the humidity map, it's rather clear that most warm areas away from the ocean/sea are screwed - it's around 18% humidity. https://www.windy.com/-Show-add-more-layers/overlays?rh,31.915,23.467,4,m:embagrZ https://www.windy.com/-Show-add-more-layers/overlays?rh,31.9...
