Photovs/Getty Images Australia's water supplies are evaporating. According to researchers at Deakin University, the country's water infrastructure loses nearly 370 billion gallons every year due to evaporation, about three times the water in Sydney Harbor. But the land down under has crafted a novel solution to persevering its water supplies, one that has an added bonus of inching the country closer to its zero-emissions goals: floating solar power cells.  Known as floating photovoltaics (FPVs), or floatovoltaics, these massive floating installations of solar panels are cropping up across Australia's dams and water reservoirs. By covering the surface of water reserves, solar panels drastically reduce the rate of evaporation. Critically, it does so without triggering algal blooms that ruin water quality, a common problem with traditional covers that block out too much sunlight.…
