Desert Solar Farms Could Generate Rain for 125,000 People

Research from the University of Hohenheim suggests large solar farms in coastal deserts can heat the air and boost convection, triggering rainfall. Simulations show two 20×20 km farms could supply water for 125,000 people a year, though costs are estimated at $38 billion.

• Two 20×20 km desert solar farms could produce rain for 125,000 people annually
• Panel heat boosts convection and cloud formation when moist sea air is present
• Estimated cost of large-scale implementation is $38 billion
• Risks include reduced rainfall in neighboring areas and lower panel efficiency from clouds
