SolarBee floating in Almaden Lake
SolarBees aerate the water to prevent methylmercury production by anerobic organisms living on the bottom. There are four SolarBees in the lake now at a cost of around $45,000 apiece.The first one was installed on May 20, 2006. They're also found in the Almaden and Guadalupe reservoirs. For more on what they're about, see the July 13, 2009 post, "SolarBees and methylmercury."
