When under water, the concrete sphere functioned like a storage battery. If it was emptied out, it had the equivalent of a full battery charge. If it was completely filled with water, it was the equivalent of a dead battery. Flooding the concrete sphere generated energy. The principle worked out flawlessly over the four-week period of the Lake ...
