Does it sound funny, impossible, futuristic? It is real and it has a name: The Sahara Forest Project (SFP). The project is about using what we have enough of: desert, sunlight, seawater and CO2, to produce what the world needs the most which is food, energy and fresh water.
Plants cannot grow in deserts because of the extreme temperatures and lack of nutrients and water. They need light for growth but they don’t like heat beyond a certain point. Above a particular temperature, the amount of water lost through the holes in its leaves, called stomata, gets so large that a plant will shut down photosynthesis and cannot grow. The solution to this problem is solar thermal technologieswith processes for saltwater evaporation, condensation of fresh water and production of food and biomass.
