Good point about the side streets, but you could still electrify where the trucks drive most often and not everything. The trolley poles could be mounted to the cab, it would seem.

The issue is that garbage trucks drive serve each street equally often, for the most part. There's no streets where garbage trucks drive more often. It's not the situation that 20% of streets generate 80% of garbage that needs to be picked up [1]. It's block after block of townhomes and mid-rise apartments that are leaving out trash bags. Overhead lines inherently lend themselves to consolidated routes, but garbage d…

Not that number exactly, but many streets or blocks have no trash - office buidings, the highrise apts you mention, parks, highways, etc. And it's time, not distance that matters - you can charge the trucks where they spend the most time. My point is that you don't need 100% coverage or likely near that.

A drawback is that garbage pickup needs probably don't align with bus, snow plowing, or other needs, so ROI is lower for those wires.

I was thinking about vehicles that can't switch to electric power. The tech's not there yet, and may never be. Cargo ships. Jumbo jets. Military aircraft. Specialized industrial vehicles, such as those used for mines. Unless these use cases are made obsolete (possible, such as military) society will depend on fossil fuels for many decades to come.

These guys seem to have a niche: hauling logs off of mountains. Regenerative braking on the way down when heavy; using a Diesel engine as a generator in the truck's engine bay. https://www.edisonmotors.ca/trucks

Battery operated garbage trucks don't sound like a great idea, at least for all day use. With the push for EV I am not sure why we aren't seeing a push for the installation of streetcar power lines, these already exist and are used for busses. If we have a garbage truck that has the battery capacity for say 30 minutes, then it could be on the power line for the majority of the time. This would limit battery waste as…

This, This, This.

We think "Well gas cars transport their own energy source, so electric cars must too" and that will probably be one of the things future generations laugh at us for (in the same way older generations thought flapping wing costumes could generate heavier-than-air flight).

Hydrocarbons are an extreme outlier in terms of energy density (vs. weight) and the fact that we are trying to replicate that model with other non-outlier materials is crazy.

Cars travel on roads almost exclusively. In the US, 90%+ passenger miles are on roads that already have some amount of power infrastructure (lightposts) and if we just made it so that our vehicles could plug into electricity at all points of their journey, then EVs are basically solved.

The sad part of Elon being so successful is that all he does is see places where we used to do things well (we electrified the whole country very quickly, built an advanced space program in 2-3 decades, etc.), notices we lack the will to keep doing those things (even I understand the overhead wires thing is a moonshot), and comes up with the pragmatic "OK but not really great" solution.

Seriously, if you had said in 1960 "the richest man in 2020 will focus on cars, low-earth-orbit rockets, and tunnel boring machines" people would be extremely bummed by the lack of progress.

The article says other cities use smaller vehicles for snow removal, so try that.

In Canada there's been some recent success using an electric cargo bike as snow plow.

I'm not suggesting that's right for New York, but maybe somthing a lot lighter than a garbage truck could work!

For these industrial use cases I’m surprised hot swappable batteries aren’t being considered more.

Are these current trucks doing 12 hour shifts plowing snow and hauling garbage on a single tank of diesel, or are they refueling? I get that fast changing infrastructure is hard and waiting 15-90 minutes to charge a battery isn’t ideal.

But couldn’t they stop to swap out batteries or have another vehicle meet each truck with replacements?

Edit: Googling suggests that garbage trucks get 3mpg on average, with a 70-90 gallon tank and go 25k mi/yr on average (80mi/day 6-day week) so one tank would cover a whole day.

3mpg is awful though which does seem to support electrification being a good plan for this use case.

Arnhem in NL and Riga in Latvia, both cities I spend a lot of time in still have them, but I wonder for how long. They're pretty iconic but every few years there is debate about whether or not it is still worth it. Another problem I forgot to mention is that these systems are not very flexible in dealing with mishaps, you can't overtake another trolley bus so if one has a problem the whole system grinds to a halt. An…

The buses I’m familiar with that use overhead power lines don’t use them exclusively - they have batteries or diesel for when they venture off the powered lines.

I wonder what they do when a bus runs out of power - towtrucks? Charging trucks?

Garbage trucks are probably one of the best places for it actually, because they stop so frequently. Unfortunately the article is about plow trucks instead which have a very different use case - New York just happens to use the same vehicles for both so they have a smaller fleet that's not as well suited to either task. For garbage trucks you have stop and go movement so EVs eliminate idling. Given the size of the tr…

> so EVs eliminate idling.

The vehicle, when stopped, has other functions to perform. It has hydraulic lifters and compactors that need quite a bit of power to operate. It's a working platform, not a simple garbage transportation mechanism.

Even to the extent is isn't for transportation, see how far away the dump is from your home. That distance has to be covered twice at least once a day, and possibly as much as 3 times per day.. and during one of those legs the truck is fully loaded with possibly up to as much as 20,000lbs of trash.

Finally, they have to operate in all conditions, in both very low and very high temperatures. The logistics of this aren't as simple as it would be for a standard vehicle.

NYC garbage trucks spend a very long time parked in front of the same building all night, crushing bags full of plastic coffee cups. Ask anyone who has ever tried to sleep in Manhattan. A completely reasonable solution that doesn't require a wholesale change in the way refuse is collected in that city would be to plug the truck in at the building where it is standing. That said, a wholesale change is what they need.

I’m very much interested in this underground system (I don’t know if it is actually implemented): https://www.core77.com/posts/102208/Amsterdams-Smart-System-... It seems to me this sort of trash deposit system would greatly simplify trash collection.

Seems like a random excuse to Trash talk unions.

Well, a union rep is quoted in the article, which was weird. His statement was also a little weird. The conclusions and the math involved don't really add up for me. They laid the groundwork for a fight against _any_ conversion to electric vehicles by warning the city council about the possibly prohibitive cost of installing a charger network... I'm not sure it's too outlandish to postulate that the union would act i…

Perhaps the union organizers think this but it doesnt really make much sense given that the trains (subway) in NYC are the first thing I would automate and apparently still have drivers. Automating trash pick-up in NYC is probably harder than L5 autonomous driving.

Here in Massachusetts we just removed our streetcar power lines (MBTA 71 and 73 trolleybus) because the wires needed to be removed during construction. This might be a logistical issue for NYC. https://www.mbta.com/news/2022-01-27/beginning-march-2022-mb...

one of the worst decisions the MBTA has ever made. battery buses are inferior to trolleybuses in pretty much every scenario, but especially winter. the battery buses they're replacing the trolleybuses with have diesel heaters to keep the batteries warm.
