Just this week I have watched two videos on YouTube where the presenter is trying to address the comments on their previous videos where people are suggesting (something like) "connect an alternator to the wheels on an electric car to generate "free" energy to run the car". These comments show a thinking, inventive mind wishing to be useful and improve things, but such a basic lack of understanding of physics. I can only think that these people weren't paying attention at High School, were (poorly) home schooled, or have some sort of incapacity to understand/believe the established laws of science. Yet they think that they can invent simple solutions which have somehow eluded the experts in the field. Perhaps it is some form of Dunning-Kruger effect.
