Black plastic balls reduce evaporation in reservoirs effectively
Studies consistently demonstrate that floating black plastic or shade balls are effective at reducing water evaporation in reservoirs.
Multiple experimental and review papers confirm that floating black plastic balls significantly reduce evaporation rates in water reservoirs, though some studies note caveats regarding ecological impacts or manufacturing costs.
