Oh yeah I guess I worded it wrong; I wasn't imagining free energy. Framing it as an efficiency question is more clear, thanks. In other words, this way of converting $natural_resource to Tesla battery level is less efficient than say, plugging into a power grid as there's an extra conversion step (ground to brakes/ambient friction).
