Not great framing because nobody made electric vehicles worse, they started off at a certain level of performance and then they'll just improve from there. Now you could say well we made snow plowing worse, and of course in this specific example you'd be right, but you'd be ignoring longer time horizons and not really comparing or accounting for the impact of negative externalities. An easy way to think about it is i…

A more apt analogy would be if you removed the existing window without having ordered a new one or found a contractor to install it.

As an EV owner. I can use my car in about 95% cases: that’s plenty! Way cheaper than gas, no maintenance required, super comfortable, etc. The remaining 5% is when I need to drive somewhere rough or when it’s very cold outside and I have concerns about getting stuck.

There is no way I will give up the convenience of EV for those 5%.

All of the above. Must Run trucks should probably be gas turbine hybrids, that can burn anything for fuel (diesel, biodiesel, Jet A, etc), versus full electric. https://www.forbes.com/sites/samabuelsamid/2016/06/07/mack-t...

>ust Run trucks should probably be gas turbine hybrids, that can burn anything for fuel (diesel, biodiesel, Jet A, etc), versus full electric. That's just high tech engineer fantasy though. Turbine is great for steady loads and terrible for cyclical loads which is what a garbage truck does all day. Electrical is great for cyclical but batteries just don't support the energy density to do it all day. You can theoretic…

Rather than running excess weight on roads, they could also deploy the shovel ready solution of liquid fuel and internal combustion engines.

Ok we'll use gas trucks forever and never change or improve or invent anything new.

Swappable batteries is how some countries are migrating to ev for motorcycle/scooter taxis, just swap batteries and keep moving passengers. The cost savings seems to be worth it, read that its about 75% savings against fuel costs. The easy solutions will go first, working its way up with better tech and design. I think car/fleet size batteries isn't really feasible with swapping batteries. Small scooter batteries see…

I don't know about this. I don't think battery swapping scales up very well. Firstly, I know someone who works on Daimler's electric trucks and he assures me that their electric powertrains are EXTREMELY dangerous just from the amount of power represented. Union operators have expressed negative interest in connecting/disconnecting the batteries outside of the factory. Secondly, the economics - the battery pack on a…

> you will probably see the size of the fleets increase

This is already happening with municipal bus and school bus fleets. The bus count is over-provisioned to allow for the longer electric 'refueling' times.

As fleet managers understand, when a vehicle is being refueled it is out of service.

In this case, I think NYC is an edge-case where they don't have a lot of room to store additional fleet resources.

That's not a good analogy because in this case the snow plows still plow so some snow is still removed. To use your analogy then they would have sold existing plow-capable trucks and not had any to plow, but that wasn't the case.

The tarp is partially effective, just like the electric trucks.

> “ With current technology, full electrification isn’t possible now for some parts of our fleet, but we are monitoring closely and really hope it will be,” Gragnani said. We are really letting the perfect be the enemy of the good. At this moment in time, Plug-in hybrids are the superior technology for nearly every application. I don't understand why they get so overlooked by consumers and manufacturers alike.

I've been saying this for years. I just don't understand it. A car that can drive ~40 miles on pure electric that has an ICE for longer trips would satisfy the needs of everyone. For like 90+% of people, it would mean never using gas for their commute while also eliminating range anxiety. I'm especially surprised about the lack of plug-in hybrids for semi trucks. I'd think having a little extra electronic torque woul…

This more than doubles the complexity, increases weight, has much lower battery capacity, and still sticks you with the maintenance work required for the ICE.

Plus gas is a very volatile mix that degrades; you must run the ICE regularly to ensure the tank gets cycled.

The MTA actually went from using a lot of hybrid buses to fully diesel at one point[0], and now they're slow rolling out fully electric by...2040[1]. Just far out enough they can do basically nothing over the next couple years, and still claim they're on track.

????

Or we can just electrify applications that currently make sense and work from there as the technology improves.

Why does critical infrastructure need to be among the first to “go green?”

Garbage trucks make almost all their emissions in the city, with their staff working around them. They work at low speed and stop and start continually.

Other than this ploughing requirement, they seem a good early opportunity for conversion.
