https://stream.echo6.co/videos/watch/ea8bc489-8fc8-4290-b798-e9098c9b06b9 Are the laws of physics being bent? Dave explains why free energy / over unity / quantum vacuum circuits are rubbish. And how to find out what's really happening here by using basic engineering principles. Can a bunch of toroids, some wire, and a simple circuit boost converter really generate more power than you put in and power 23 LED's for 52 hours? He goes through the claims and debunks them one-by-one. Explains how the circuit works and then builds up the circuit and takes some measurements to show that the energy can easily come from the battery and not some quantum vacuum. This is as much a demonstration of basic ballpark system engineering, calculations, and understanding, as it is debunking.
