" It's a dehumidifier; in places where the air is wet, it rains, and you don't need it. In places where you need it, you need it because there's not much water, so it doesn't work well."
I wonder how well it would work as a stand in for a desalination solution. Where there's all the water you want but it has salt (or other contaminant) that makes it impossible to drink. Seems to me that a beach would be the perfect place for it. At $150 price point it's a very good alternative to high price machinery.
- jodrellblank 5y agoDesalination produces a lot more water-per-KWh-energy than unboiling water from the atmosphere. Elsewhere in this thread someone linked a paper which estimates up to 100 litres per KWh for desalination, vs ~1 litre per KWh for condensing. Saving on machinery, or chemicals, might be important but $150 of materials for a device will buy you ~25,000 litres of water in bulk (in the USA).
