Still Lifes Lit By Their Own Electricity Brings Science and Art Together
This witty and gorgeous photo series, Back to Light, from photographer Caleb Charland, has fruit, vinegar and loose change generating enough power to light lamps and LED lights.
"By inserting a galvanized nail into one side of a potato and a copper wire in the other side a small electrical current is generated. The zinc coating on the nail gives off electrons due to the electrolyte environment within the potato. These electrons then travel along the copper wire providing the electrical voltage to illuminate a small light emitting diode. The utter simplicity of this electrical phenomenon is endlessly fascinating for me."
