Let's suck our way to generating electricity using Lego! In this video, we experiment with a few different 'Lego Vacuum Engines', and use a powerful turbine engine to drive a Lego generator made of large neodymium magnets and 3 coils of copper wire. This generator outputs a 3 phase signal, giving us a nice smooth signal at quite a high voltage. The current is limited, but this gives me great hope for an upgraded version with beefier coils!
Now it's not lost on me that we're using a 620 watt hoover to generate only a small amount of power. But this sure has been a fun experiment using a vacuum to drive our turbine, and then using this to drive our generator.
