Improving solar cell efficiency with a bucket of water

Beth Parks has devised an astonishingly simple way to overcome a limitation of solar cells -- a bucket of water. She developed a frame that holds the solar cell with a bucket suspended on either end. By controlling the leak of water from one of the buckets, the solar cell shifts, tracking the arc of the sun throughout the day.
