ILLUMINATION OF THE WEEK: THE GRAVITY LIGHT
by Hazed
Sometimes somebody comes up with an invention that makes you go, “Why did nobody think of that before?” Such is this amazing light, powered by gravity, and intended for use in poor countries that currently have to rely on kerosene to power their lamps. You tug on a string for 3 seconds, and that powers the light for 30 minutes.
Genius!
