For more on Atmospheric and Fog Water Harvesting, the following paper is well worth a read.
To summarise it; stainless Mesh 20 with 0.4mm wire.
It’s been discovered by University of Kansas researchers that filling a chamber with acetylene and oxygen, the same gasses used in welding and cutting torches, can produce quantities of graphene when ignited by spark plug at one atmosphere.
The engineers in the room will be thinking oxy-acetylene soot:
rotting fruit and veg, compost pile emissions, and growing trees produce ethylene, and trees tend to emit it during drought.
It makes this person wonder whether other wood/biochar/biodigestor gases could also be made to work.
Nitrous oxide is 300 times more effective at trapping heat than carbon dioxide and 10 times more effective than methane. Nitrous oxide also moves into the stratosphere and destroys ozone. Now a new pathway in the nitrogen cycle has been discovered that avoids nitrous oxide production.
