Buses don't need huge batteries for their size. A typical city bus goes only about 100 miles a day, they do a ton of regenerative breaking, and they can charge at stops and also they tend to sit in the terminal several times a day while the driver takes a break after each circuit.
Electric trash collection trucks are even better. That's because they do so much regenerative breaking.
- goldenkey 9y agoRegenerative braking doesn't do much for someone who already throttles properly. Garbage trucks dont have to drive in traffic. They dont get free energy for regen breaking..its just a recoup for bad driving conditions.
- adrianN 9y agoWere I live buses do drive in traffic.
- goldenkey 9y agoYes, buses do. But not garbage trucks...Please read my post again - I never referred to buses, only garbage trucks.
- eric-hu 9y agoGarbage trucks still need to make frequent stops compared to most vehicles. I suppose it's possible to make some kind of pickup system that doesn't require stopping, like the mail systems trains used to use. I don't know of any place that does that though. It'd probably get messy pretty easily.
- goldenkey 9y agoGarbage trucks cruise at a certain pace. They hardly ever stop and go, for good reason: fuel efficiency, wear and tear, and just general work efficiency. The drivers jump on and off and back onto the truck. Have you ever watched a garbage truck squad in action?
- woodandsteel 9y agoWhere I live, the trash collection trucks have a hydralic mechanism on the side that grabs a trash can, pulls it up, and dumps it over the top. And to to do that, it comes to a full stop. The system you are describing sounds dangerous and uses far too much labor. Maybe your city has a trash collectors union with too much power.
- goldenkey 9y agoI'm talking about NYC...it has been working well for the last 200 years with little in the way of change. I'd say the city knows exactly what it is doing... Having the collectors use a robotic arm rather than just a fleshy garbage man for dumping the bin..that's only something you see in "new cities" that have no clue on how to do efficient garbage collection. Now..."YO!! get offa my steps you stoopidabass!! go backtoodah burbs ya yankee dandee sass platoon!!" ;-)
- woodandsteel 9y agoICE garbage trucks brake all the time. They get up to speed, go a very short distance, and then put on the brakes so they can make their next pickup. There is no way they can let off the throttle and glide to a stop in time. Nothing is more stop-and-go than a garbage truck in a city.
