This is a high school physics. But could make a massive difference to life on earth. Wherever we have a stream or river or sea water, we have access to water.
But we need to remove the bacteria and pollantants. Professor Argent was always very focused on heavy metal. By filtering them out uses a lot of energy, and needs regular filter changes.
This is not how nature does it! It evaporate sea water, to farm fresh water vapour, which then falls as rain.
High school physics teachers us that room temperature water will biol under one metre all vacuum pressure. Vacuum is very lower power to generate.
1 E=P*V where P=0.1 atmospheres
So a hand crank linked to a one metre telescopic stand and extensible water hose, will suck water into a stream of pure water vapour. We use it to fill a water jug.
Or a static vacuum pump will transfer the water vapour to a small water tank. Providing fresh water for a town or village in the third world, from a small solar panel, donated by the first world.
Saudi Arabia can afford a plant, to suck sea water into water vapour, and transfer this to the high desert. When we vent it to the air, it will fall as the water droplets. To fill an artificial reservoir all over the world. Free drinking and irrigation water.
This idea, can be used to supply pure water to the driest areas in the world. Dredge up soil from the sea bed, wash the salt out in river estuaries. And form soil mats impregnated with grass seed. We also need to plant seedling lines; with soil balls, to act as windbreaks on field boundaries.
All this extra plant growth, will suck carbon dioxide and nitric oxides from the air. But already global photosynthesis caps free carbon dioxide in the air at 2 parts per million: NOx at 4 parts per billion.. No increase of these oxides in the air since industrial revolution, is biologically possible.
That is paid fiction from the paid stooges to nuclear power. This is the sort of work people already give money to Water Aid to provide to the third world.
