Earth movers carrying loads up out of a pit, or the giant farm tractors that are now required to grow enough food for 8 billion people, run at 40% thermal efficiency so unlike a car, there is only slightly better than 2:1 efficiency to be gained. And are not convenient to run on a cord. You will need a MWh battery to take the place of each 400 Liters of fuel.
Yeah,that looks good!
I came up with 1.693-MWh as an electrical equivalent for the diesel,and since half the mileage is 'downhill',with a regenerative fudge-factor,1-MWh is real reasonable.
