This is a demonstration of the "geyser switch" that resets from ebb to flow in the systems.
The playlist is at http://www.youtube.com/playlist?list=PLkzXlmAwZTZe4fNnDOr43MQls5QxLd5wl and it is about doing ebb and flow hydroponics powered by an air pump instead of a water pump.. You could do it with solar or directly produce the low pressure  air with a trompe from water power in a small stream.
can u show us how u made it ?
have u thought of hooking up solar as well?
