> Harvesting energy from cars is also a non-starter. Any energy you harvest there is added as a load on the engine of the cars, which are all powered by fossil fuels. It's a really inefficient way to turn a car engine into an electric generator.
The vast majority of cars already have a small electrical generator installed. Plugging things into a cigarette socket to access that electricity causes 0 extra load on the engine.
