There was recently an article here about an electric truck that never needs charging. It drives up a hill, collects a load of rock from the mine there, and by the time it has driven back down with the heavy load, regenerative breaking has recharged the battery.

While that makes perfect sense, I have read journalists claiming that Teslas were 110% efficient because of regenerative braking.

A pile of rocks on a hill is a renewable energy source if you are prepared to wait a few billion years for plate tectonics to recharge it.

Soon we will be hearing of the global flattening.
