The 'Energy Saving Light' by Randy Sarafan is an eco-focused device that turns off a lamp when a person closes their eyes to blink. Sarafan invented this device in honor of Earth Day and in an effort to reduce his personal energy use and carbon footprint.
The gadget works by attaching electrodes to one's face then plugging those into the machine. This device can be made by anyone who is a little tech-savvy and there are instructions on how to build it on Sarafan's 'Instructables' post which is linked below.
Sarafan hopes that his invention can be used in televisions, computers, and electric cars in the future to further reduce wasted energy. He even mentions that he is "confident that future generations will thank [him] for this innovation."
