Leave it to Californians to deliver one of the greatest(and simplest) innovations in sustainable technologies.  Within the past week, officials have released over 96 million black plastic balls into the Los Angeles Reservoir.

What for?

These roughly 4-inch diameter black plastic balls are providing necessary shade for the reservoir.  They float atop the surface of the 175+ acre man-made lake. The purpose is to prevent chemical reactions from taking place, with the absence of ultraviolet light.  Light has a tendency to cause algae to bloom and the breakdown of necessary minerals and safety additives.

This is not the first time balls have been employed to address aspects of the drought.  They have been used since 2008 in several other reservoirs.
