Still types include large scale concentrated solar stills and condensation traps. In a solar still, impure water is contained outside the collector, where it is evaporated by sunlight shining through a transparent collector. The pure water vapour condenses on the cool inside surface and drips into a tank. Distillation replicates the way nature ...
A typically 25% efficiency standard solar still (not allowing for any recovery of rejected latent heat), as the latent heat of vaporization of water is 2.26 MJ per kilogram, [3] should evaporate 2.4 kg (or liters) of water per m 2 per day in a region with an average daily solar irradiation of 21.6 MJ/m 2 (250 watts/m 2), or 873 liters per year ...
Solar distillation has been used for thousands of years. Early Greek mariners and Persian alchemists produced both freshwater and medicinal distillates. Solar stills were the first method used on a large scale to convert contaminated water into a potable form. [2]
“Large-scale renewable development should be prioritized on structures or lands that have already been degraded from their natural state.”
A large-scale solar distillation project was first constructed in 1872 in the Chilean mining town of Las Salinas. [48] The plant, which had solar collection area of 4,700 m 2 (51,000 sq ft), could produce up to 22,700 L (5,000 imp gal; 6,000 US gal) per day and operate for 40 years. [ 48 ]
The proposals for 10 large solar farms across the East of England and Northamptonshire involve about 24,000 acres of land and could generate a combined 4.3 GW of electricity - more than the new ...
Around the turn of the millennium up to about 2010, there have been several proposals for gigawatt-size, very-large-scale solar power plants using CSP. [127] They include the Euro-Mediterranean Desertec proposal and Project Helios in Greece (10 GW), both now canceled. A 2003 study concluded that the world could generate 2,357,840 TWh each year ...
