Solar powered water circulation

At Shoreline Lake in Mountain View California water is being purified using solar technology created by a company called SolarBee. Their solar powered water pump or "long distance reservoir circulator" improves water quality in fresh lakes by reducing or eliminating the need for algaecides and herbicides.

I had always wondered what these things were, I often windsurf on Shoreline Lake and had seen the funny looking buoys with solar panels on top. As I read the winter Mountain View Newsletter I noticed that our city had won an award for the installation of solar powered pumps and it all clicked. Currently, the pumps are being used on Shoreline Lake and the City reservoir. Check out their promotional video below; note that it does not feature Shoreline Lake.
