This community exists as a sister community/copycat community to the r/fuckcars subreddit.

This community exists for the following reasons:

You can find the Matrix chat room for this community here.

Rules

  1. Be nice to each other. Being aggressive or inflammatory towards other users will get you banned. Name calling or obvious trolling falls under that. Hate cars, hate the system, but not people. While some drivers definitely deserve some hate, most of them didn't choose car-centric life out of free will.

  2. No bigotry or hate. Racism, transphobia, misogyny, ableism, homophobia, chauvinism, fat-shaming, body-shaming, stigmatization of people experiencing homeless or substance users, etc. are not tolerated. Don't use slurs. You can laugh at someone's fragile masculinity without associating it with their body. The correlation between car-culture and body weight is not an excuse for fat-shaming.

  3. Stay on-topic. Submissions should be on-topic to the externalities of car culture in urban development and communities globally. Posting about alternatives to cars and car culture is fine. Don't post literal car fucking.

  4. No traffic violence. Do not post depictions of traffic violence. NSFW or NSFL posts are not allowed. Gawking at crashes is not allowed. Be respectful to people who are a victim of traffic violence or otherwise traumatized by it. News articles about crashes and statistics about traffic violence are allowed. Glorifying traffic violence will get you banned.

  5. No reposts. Before sharing, check if your post isn't a repost. Reposts that add something new are fine. Reposts that are sharing content from somewhere else are fine too.

  6. No misinformation. Masks and vaccines save lives during a pandemic, climate change is real and anthropogenic - and denial of these and other established facts will get you banned. False or highly speculative titles will get your post deleted.

  7. No harassment. Posts that (may) cause harassment, dogpiling or brigading, intentionally or not, will be removed. Please do not post screenshots containing uncensored usernames. Actual harassment, dogpiling or brigading is a bannable offence.

Please report posts and comments that violate our rules.

"Just to meet business-as-usual trends, 115% more copper must be mined in the next 30 years than has been mined historically until now," the study said.

Some of the stuff about that company says it’s doing aluminum windings and some of it says they’re doing no windings with flux barriers and air gaps. What’s up with that, different experimental technologies?

I’m skeptical of their claims about it being environmentally friendly since more stuff made out of aluminum means more aluminum being pulled out of the ground, but it’ll be interesting to see that develop.

E: their claim that it’s environmentally friendly because it’s got less rare earths makes sense now because they gotta use iron instead cause of the resistivity. I’m genuinely interested to see how much weight or volume savings they get and the efficiency for a given power output compared to a traditional copper and rare earth motor.

It really seems like a strange step backwards (not an insult, plenty of old technologies are perfectly valid and their manufacturing techniques need to still exist) to get cheaper components that sidestep the cost of shipping recycled copper around.

At some point the high cost of recycled materials has to be integrated into the supply chain somehow otherwise the benefit of having recycled them will never be realized. This technology seems like a scheme to increase consumption without dealing with the consequences of previous consumption.
