Determined to make it happen for reasons I’ll never understand, this is a video of Youtuber Engineezy designing and building a machine that harvests the energy of falling marbles to charge a phone. Does the device consume more electric energy lifting the marbles than it produces? What do you think? And if you think maybe it doesn’t, we should probably have a conversation about getting you reenrolled in a high school science class. Physics, just to be clear. “I was hoping for biology.” Your wiener is useless and that’s all you need to know.
