Wind Turbines on EVs and Why That’s a Bad Idea

Here’s an article on EVs that explores the topic in the title above.  The fellow admits that he’s not an engineer or a physicist but observes, correctly, that attaching a wind turbine to the top of an EV and using it to charge the battery cannot possibly have a net positive effect, due to the first and second laws of thermodynamics.

I’m reminded of a guy who contacted me with an idea that was rooted in hydrokinetics, but from what I could gather over the phone, it sounded like it was entirely self-contained.  “Where does the energy come from that makes the water move?” I asked.  “Think of it as a river in a box,” he replied.

I resisted the urge to laugh, and explained why that was impossible.  “Oh, it works, he insisted.”

I told him I had something burning in the kitchen, and had to go.
