My understanding: As the water condenses onto the next surface layer in the stack, the solar heat is recycled. This is because the transition from gas to liquid releases heat.
Really clever stuff!
Edit: mixed up evaporate/condense
- ppf 5y agoFor that to work, each successive layer will need to remain cool enough for water to condense on it.
- Retric 5y agoIt’s due to changes in pressure. https://upload.wikimedia.org/wikipedia/commons/thumb/3/33/Phase_diagram_of_water_simplified.svg/1024px-Phase_diagram_of_water_simplified.svg.png https://upload.wikimedia.org/wikipedia/commons/thumb/3/33/Ph... At 5ATM water condenses at a higher temperature than it boils at 4ATM.
