  • I know all that. I’m talking about the moving parts in the ENGINE, which then would not exist. A brushless DC drive motor only has bearings to worry about. A gearbox is necessary but a well-made gearbox should last for decades and is way easier to rebuild than an entire ICE engine. Of course suspension and brake parts wear out over time, but as you can see I wasn’t referring to those any more than I was referring to tires. All those things are cheaper and easier to replace, really, than having to worry about an entire ICE engine, with the fuel system, cooling system, and exhaust system to worry about. At worst an EV might have a motor or it’s inverter go bad, and of course the battery pack has a limited lifespan, but those are essentially drop-in replacements compared to what you have to go through with a modern ICE and all the crap attached to them.






  • It’s more than just a rectifier. LEDs of any type, white or otherwise, require regulated current, not just any voltage, otherwise even an LED will burn out. Vis-a-vis: cheap white LED flashlights that take 3 AA or AAA batteries; there’s no current regulation, they just call it ‘close enough’. Over time some of those LEDs will fail and start flashing when they heat up. So what usuall fails in white LED bulbs in your house is the electronics responsible for regulation. Sometimes the LEDs themselves (of which there is usually more than one LED, they’re usually an array of several) will burn out, killing the whole bulb. I have a 1080p TV that the backlight went out on it after a few years use, which I replaced myself. Inside it are three circuit board strips with white LEDs on them, all wired in series like christmas tree lights used to be wired. All it takes is one of them opening up and the whole backlight stops working. Anything like this that is manufactured at massive scale is bound to have some failures, and white LEDs and white LED bulbs are no exception.


  • With so many fewer moving parts compared to an internal combustion engine, yes, EVs could be durable enough to be handed down from generation to generation. Just keep replacing the few moving parts that wear out. Worn interiors can be refreshed. Electronics are modules that can be replaced with updated versions.

    What we have to look out for here though is this overall trend of ‘rent everything own nothing’, though. Car companies might try to make vehicles lease-only, so you have all the responsibilities of ownership but none of the benefits of ownership, and it’s never paid off, you just pay forever.
