The Fair Energy Clock, conceived by industrial designer Pablo Santiago Cantera offers a sustainable solution to the superfluous use of energy. The fully automated device cuts and reconnects the power supply to battery chargers and similar discontinued use systems. The clock asks the user to select his preferred hours of charging: continuous, a holdup, or several of them, and later, severs the connections depending on the time provided. It's perfectly compatible with a standard power outlet.
