Solar Clock Needs No Batteries

The Solar Clock is pretty self-explanatory – it is powered by the sun’s rays, which means you virtually won’t need to replace the batteries on this thing for all eternity. The solar panel is located right up front (the only logical choice for obvious reasons), and it can be mounted either vertically or horizontally, depending on your preference. At least this is way more accurate compared to a sundial, and it doesn’t end up polluting the environment with discarded AA batteries either. The design could do with some improvement though.
