Comment Sounds like Tesla's Gigafactory can be used (Score 1) 491
.. to provide batteries at 1/3rd their current cost.. then the bus will have ~100 mile range while costing the same. (Space/weight isn't an issue, since a regular diesel bus already weighs around 75,000 lbs.)
Better yet, have batteries slotted into the bus like a giant laptop battery. A robotic arm can swap them out in seconds.
