Power plant operator and YouTuber ‘Thomas Kim’ can charge his iPhone using a stream and a DIY hydro-electric generator made from plastic bottles, some disposable plates, a 3 phase stepping motor, and a rectifier circuit. He demos the water wheel by powering a phone and a small panel of LEDs.
Labeled with the caption ‘Made by JM’, Kim’s YouTube channel is full of interesting science experiments, some more dangerous than others.
