Interesting design making agriculture in "hot and dry coastal regions" all the more efficient...

It a seawater-powered and it's engineered to work with the variety of climatological region that has easy access to salt water, but maybe not fresh water... yet still do water-intensive agriculture.

"A greenhouse produces crops year-round in hot dry areas using only seawater and sunlight. Tomatoes, cucumbers, peppers, lettuce, strawberries, herbs—anything that can be grown in traditional greenhouses—can be grown in seawater greenhouses. The award-winning technology, invented by Seawater Greenhouse Ltd. founder Charlie Paton, was inspired by the natural water cycle where seawater heated by the sun evaporates, cools to form clouds, and returns to earth as precipitation."

"The idea behind the process is simple. It combines two unlimited resources - sunlight and seawater - to provide ideal growing conditions for crops in hot, arid environments.

The innovation [uses] the cooling and humidifying power of water vapor produced from evaporating salt water. Using modeling and simulation techniques developed in collaboration with our partners at Aston University, we are able to process local climate data to predict greenhouse performance and inform the design. The combined effect of reducing temperature and increasing humidity, together with providing a protected environment for crops, results in up to 90% reduction in Evapotranspiration. This to greatly reduced irrigation requirements, which can be provided by desalination, and improved growing conditions."

This one is for my pals @sunbeam.city 🤟

So in July of 1974, the "old-timey hippie" generation (my parents' generation) was in their mid 20's to mid 30-ish. Those hippies had just barely just convinced the world that it probably wasn't the best idea to go on with the catastrophic pollution crisis which Mother Jones so bluntly captured here: motherjones.com/politics/2011/

They were pioneers of their own right, showing that those toxic chemicals were a poor replacement for the natural energy of the sun, which can be used to meet all of our human needs for energy in one form or another.

From the magazine featured below, they shared a design of a . It's based on the concept of a Fresnel Lens, a sort of "grooved" lens that is specifically designed to concentrate rays into a high-heat situation to cook food or make an oven!

Just goes to show that high-tech does not need to be elite-tech.

Happy Memorial Day to the generation that knew we didn't need GUNS to make peace.
