Have they thought this through? To install batteries that are much heavier than what the bus trip requires makes the bus less efficient. Research in the UK found that a bus carrying 5 people is about as efficient as 5 cars each carrying 1 person. That’s because of the weight of the bus. So the goal should be to fill the bus with people, not excessive batteries and overhead that need not move back and forth from A to B which then requires more riders to maintain the same efficiency.
Sure they need to store energy for to smooth out peak grid consumption but probably smarter to do that with stationary batteries -- if they must use batteries. Another way to store energy: pump water to the top of a mountain and open a dam that turns a hydro turbine when they need the energy back.
from the article:
Seems like a stretch. Even if they can attribute chronic absenteeism to air pollution and keep a straight face, moving the pollution of a fleet of buses that makes 2 trips/day from the street to the power plant isn’t going to change the absenteeism by reducing asthma. This claim only signals a bit of desperation to get support.
