Yesterday I discovered natures most versatile energy source – potatoes. With a few tweaks your everyday carbo load can be turned into a super spud that can power an alarm clock!!
The Citrus Clock is an experimental timepiece designed by Anna Gram that actually runs on lemons! It works by using the same principles of electrolysis that is used in conventional electric batteries. The acid of the open-faced lemon interacts with the copper and zinc plug it sits on to create enough power to run the digital clock for a week or longer.
“This pedagogic project is a kind of shortcut intended to remind ourselves that nature, in spite of the various transformations to which we subject her, is still our direct energy source. ”
