Remember that yeast-and-sugar-powered generator
from Dr. Cedrick Ngalande of Malawi we spotted a while back? Ol' Ced's back with a video of the system in action -- and an explanation of how it works, to boot. Just as most of you guessed, the system is powered by the yeast / sugar mix giving off CO2, leading to a pressure imbalance which tips the center of gravity and causes motion. What most of you didn't
guess, however, is how freaking slowly that would happen -- check out the video after the break, and then wake up and wipe the drool off your face, slick.
