Back to Light—an artistic
take on the classic potato-battery science project.
1. Back to Light
My current body of work, Back to Light, expands upon a classic grade-school
science project, the potato battery. By inserting a galvanized nail into one side
of a potato and a copper wire into the other side a small electrical current is
generated. The utter simplicity of this electrical phenomenon is endlessly
fascinating for me. Many people have had the experience of drawing power from
fruit in the classroom, and it never ceases to bring a smile to the face or a thought
to the mind. This work speaks to a common curiosity we all have for how the world
works as well as a global concern for the future of earth’s energy sources.
Demo Hour highlights new prototypes
and projects that exemplify innovation
and novel forms of interaction.
