NO. For the million(+3)th time, it's NOT NEW.
Elon boasts about his NEW INVENTION of regenerative braking, and his NEW INVENTION of cars that put energy back into the grid.
As usual, not new. One hundred years old.
From 1919 Railway Engineering Journal:
(Got wheels?)
This 28-wheel monster had regen braking, and fed the generated energy back into the power line. Other electric locos with the same characteristics were running routine service in the coal-mining area of West Virginia.
Why did Norfolk & Western decide to use electric locos to haul coal?? Exactly because of the regen braking. Downhill trains were feeding power back, which was then used by uphill trains on the same line. Required less surge capacity in the central generating plant.
