This unique piece tells the true solar time anywhere in the world using just the power of the sun, achieving surprising accuracy estimated by experts to be better than +/- 10 minutes. Once set up it is also a model of our planet with the bridge parallel to the earth's axis, so it can thus be used as a precise compass too. The outer and inner rings can be folded together for easy transport.
