Science Saturday – Making Electricity From Water

Kelvins RainstormThis week’s Science Saturday is all about power. No, not the type that Russian dictators crave, but the stuff that the dying battery on your mobile phone craves. This is a weird take on hydroelectricity known as Lord Kelvin’s Rainstorm, and discovered by the great man over a hundred years ago.

The bit I like the most is seeing how the charged water droplets are attracted to the sides of the tubes as they fall, and then as soon as the spark is released they move back to the centre of the twisting tubes.

Have a look at the video and always keep learning.
