How efficient is laser weeding in time and energy?
Like, can the robot move down the row as fast as a human weeding by hand? Can it carry a car battery and weed for an eight hour shift?

Speed of movement / detection / destruction cycle isn't as important as cost per unit of land patrolled - these are things you can easily scale up if the price per device is low enough. Compare & contrast cost of humans.
And regular sweeps means you won't be seeing hundreds of weeds per square metre, certainly not once the primary crop's established.
I recall the Bosch weed-stamper robot from a few years ago were pretty happy with ~ 2 weeks per second stomping rate.
