Timeless Garden Concept

Another day another clock gadget, this one is called the Timeless Garden.  Its called the Timeless Garden because it in theory is just that a clock and a garden all in one.  The clock is powered by the chemical reaction taking place between soil in the garden with the metal casing, therefore no batteries or electrical outlet is required. I presume the water you give to the plants is also involved in the chemical reaction, however dont quote me on that.
