Kelvin’s Thunderstorm

Featured Video Play Icon

In this video, Derek Muller explains how an experiment known as Lord Kelvin’s thunderstorm generates electricity from falling water. The set-up relies on a positive feedback loop that creates a separation of charge between the two streams of water. Check out the video for a great demonstration and explanation. If you prefer your science with a more dystopian flavor, there’s a second version of the video made in collaboration with the Hunger Games movies.  (Video credit: Veritasium; submitted by entropy-perturbation)
