How-To: Energy-Saving Light shuts off when you blink

Randy Sarafan writes:

In the spirit of Earth Day, I have created a revolutionary new energy-saving lighting solution that is only ever on when your eyes are open. This is remarkably more efficient than normal lighting that remains on, even when your eyes are shut. Using my device, you get light when you need it, and darkness when you don’t. This is not only beneficial to you and your energy bill, but great for mother Earth.

To use it, you need to attach some electrodes to your face. Place one under your eye, one to the side of your eye, and one directly behind the ear.

Connect the red cable to the one under the eye, the white cable to the one next to the eye and the black cable to the one behind the ear.

Caution!!! Connecting your face to a DIY device that is plugged directly into the wall is a terrible idea. This Instructable was for entertainment purposes only. You should never replicate this.

  1. Sounds like a fail as the amount of energy to light a bulb is more that with would be to leave it running for half a second.

  2. But then you have the same problem as you do with rerigerators … how do you know if the light is off or on when you close your eyes!

  3. @hellonearthis , not really, the start up wattage difference is negligible. There’s a mythbusters episode on the start up / shut down of energy used, where they proved that it’s really more of the type of light bulb that makes a difference, and that for all light bulbs, the steady state is almost instant.

    Overall comment on the video: What could possibly go wrong?
