In Los Angeles, California reservoir, as in various Florida water body, algal growth is a problem that needs to be dealt with. Besides my previous post suggesting the use of floating solar panels in reducing algal growth while generating power, Consider Using Floating Solar To Reduce Blue-Green Algal Blooms Now Is 3 Central Florida Lakes, here is another ingenious way in reducing algal growth, using black shade balls, to reduce algal growth and evaporation.
In the video published by Veritasium youtube channel, on May 10, 2019, “Why Are 96,000,000 Black Balls on This Reservoir?” below:
Los Angeles is throwing shade at its water problem — literally. The city has deployed a total of 96 million “shade balls” into the LA Reservoir in an effort to save 300 million gallons of water. California is currently in the midst of its worst drought on record, and all hands are on deck to conserve the state’s precious water supply. The Los Angeles Department of Water and Power, for its part, is contributing to the effort by rolling out thousands of small, black plastic balls to protect water quality by “preventing sunlight-triggered chemical reactions, deterring birds and other wildlife, and protecting water from rain and wind-blown dust,” according to a press release from LA Mayor Eric Garcetti, in the video published on August 13, 2015, “LA throws 96 million ‘shade balls’ at its water shortage – and it’s mesmerizing | Mashable“
Derek Muller (creator of Veritasium youtube channel) took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they’re there. The first time I heard about shade balls the claim was they reduce evaporation. But it turns out this isn’t the only reason they were introduced, in the video published on May 13, 2019, “Why are 96,000,000 black plastic balls in this L.A. reservoir?“, below:
Derek Muller (creator of Veritasium youtube channel ) bought 10,000 shade balls and tried to swim in them. They appear to act like a non-Newtonian fluid: rigid under high shear stress, but they flow like a liquid under low shear, in the video published on June 13, 2019, “Can You Swim in Shade Balls?” below:
I wonder if Florida may be able to incorporate both floating solar panels and black shade balls to control algal growth.
