A clock that runs only w/ lemons ?

Citrus clock / Anna Gram studio

 

An experimental clock that runs on the energy of a lemon, designed by Florian Dussopt and Julie Girard from Anna Gram studio. The acid of the open-faced lemon interacts with the zinc and copper plug it sits on to create enough power to run the digi clock for a week or longer.
