California to Build Solar-Powered Canal.

California is funding a pilot project to cover the state's canals and aqueducts with solar panels to reduce water evaporation and generate renewable energy. The $20 million project, a collaboration between Solar AquaGrid, the University of California Merced, and the state of California, aims to test the concept in Stanislaus County. The project could reduce evaporation by up to 90%, saving 63 billion gallons of water per year, while generating energy and improving air quality.
