Florian Dussopt & Julie Girard designed this desk clock that’s powered by one of my favorite early chemistry experiments: the Citrus Clock has zinc and copper electrodes under the lemon halves and through oxidation and electrolysis, powers the clock. I bet it makes your desk smell nice, too. Via Core77.
