trainsarebetter··on Nissan's third generation e-POWER powertrain
Nice to see the packaging improvements, but the modularity of the original leaf motor enabled them to be come a budget staple motor choice for ev conversion
trainsarebetter··on GM Backs Sodium Ion Batteries for U.S. Grid Storage
Check out https://github.com/dalathegreat/Battery-Emulator

Re use old ev batteries unmodified for battery storage

trainsarebetter··on Mercedes‑Benz starts large‑scale production of electric axial flux motor
This is happening now in the openinverter.org community
trainsarebetter··on The Internet Is a Net Negative
When you no longer have angency or ownership over your own capital, it’s not capitalism, it’s feudalism.
trainsarebetter··on Can “second life” EV batteries work as grid-scale energy storage?
30000? What? Leaf packs are swap able between years… here in bc 2k and you have a newer pack in

1st gen was LMO
trainsarebetter··on 3M May Escape Toxic Chemical, PFAS Manufacturing Legacy
Okay so how are you going to filter all the water in every water shed, pond, lake, estuary, etc?
trainsarebetter··on The climate case for planting trees has been overhyped – but it's not too late
We could start with just stop cutting down the old growth ones that are still left
trainsarebetter··on How much do electric car batteries degrade?
Oh yes, the entire heating/cooling system is quite a beautiful bit of engineering. a very elegantly designed “supper manifold” and heat exchanges that can push or pull heat from any device to another in the vehicle. They don’t even have heating elements anymore, they just run the motor less efficiently to produce more heat!
trainsarebetter··on Countrywide natural experiment links built environment to physical activity
That’s my point really, we just commercialized everything, and introduced a bunch of extra steps. Could argue it enabled us to scale and handle very large amounts of people residing together.
trainsarebetter··on Countrywide natural experiment links built environment to physical activity
It’s funny how as we increase a nations gdp, and general wealth, we commodify everything. day care, dog walkers, psychical activity, etc and then we have to go back and do all this market research and artificially recreate what was holistic about the more rural way of life.

There really is no free lunch!

trainsarebetter··on Mark Zuckerberg's vision for humanity is terrifying
deleting fb and instagram, essentially when I was a teenager (which I saw early on was contributing to my depression) was best decision I every made. I moved to a small town from the big city and learned to socialize with people. Coming back old friends comment of how outgoing and easy it is for me to connect with people.
trainsarebetter··on Enough AI copilots, we need AI HUDs
this is true, so we just lack the incentives to make them? a human copilot is just a core part of the sport?
trainsarebetter··on Enough AI copilots, we need AI HUDs
This is I’d say partially because we don’t have a HUD that can handle the bandwidth and pace of data required for rally. Overlaying a visualization of the turns ahead would be much better than a copilot for sure
trainsarebetter··on Return of wolves to Yellowstone has led to a surge in aspen trees
This is pretty naive take. We have turned eras of lush forests into essentially deserts and killed water sheds. These things don’t default back to a thriving ecosystem. Lots of the time they are just dead. Pre tree planting, after clear cutting, there’s a lot of “forests” in bc that are just one canopy hemlock swaths. They need to be thinned and diversified because the are essentially “dead” forests. A lot of work needs to be put into these areas, as the water sheds are falling apart and dying as a result.
trainsarebetter··on How Tesla is proving doubters right on why its robotaxi service cannot scale
Good design is good design. Road dosnt need to be anything more than a path with consistent surface texture.

If we want to develop general purpose machines, then we can rely on placing external sensors in the environment

trainsarebetter··on How Tesla is proving doubters right on why its robotaxi service cannot scale
It’s not binary. You ran way too far. having simple, generalized infrastructure that’s repair ability can be democratized, and having a free market of what can use said infrastructure is robust. Road infrastructure cost a lot of money to maintain, adding more technology to maintain makes no sense
trainsarebetter··on How Tesla is proving doubters right on why its robotaxi service cannot scale
Nonono. Externalizing the part of the compute is bad idea. increasing the cost and complexity of a socialized infrastructure is bad as now it relies on external reliability, we can barely maintain roads in there current form
trainsarebetter··on Tesla launches robotaxi rides in Austin
That’s a good point. I coming from the perspective that waymo is more of a “dead reckoning” approach compared to Tesla long(and maybe never ending) road.
trainsarebetter··on Tesla launches robotaxi rides in Austin
The psychological distinction is definitely something that was perhaps overlooked. we need to put the blame on some one, for closer. Loosing to some rounding error definitely is haunting
trainsarebetter··on Tesla launches robotaxi rides in Austin
Short term, perhaps, long term they might end up with a more generalized robot operating system. It’s definitely more flexible
trainsarebetter··on Tesla launches robotaxi rides in Austin
Sounds like there’s actually around 32ish, based on photos from the “war room” where all the engineers have live feed from all the cars and 112 rides ? https://x.com/aelluswamy/status/1936865682810946035
trainsarebetter··on Tesla launches robotaxi rides in Austin
No bicycles? That is ridicules. Many city’s are now trending towards people centric design. Bikes are a key part of that
trainsarebetter··on Zombieverter: Open source VCU for reusing salvage EV components
Included me methods for ccs
trainsarebetter··on Heat stress mitigation by trees and shelters at bus stops
But buses actually don’t. you just pay for it later. Roads are one of the fastest deteriorating forms of infrastructure. the hole “ but rail dosnt make money” argument ignores the fact that… roads don’t ether
trainsarebetter··on Waymos crash less than human drivers
This.
trainsarebetter··on Waymos crash less than human drivers
okay great so it’s safer than a human driver… but this seems to be the wrong metric?

not that it can drive safer, but make things safer for everyone?

If the crashes it was involved in where the result of the waymo following the rules… how is that any better?

Less crashes, not it crashes less. Isn’t that the real goal?

trainsarebetter··on Tesla speeds Supercharger installations up with foundation that skips concrete
The fact that they no longer require concrete to install is a huge win. Concrete is a very labour and co2 intensive material
trainsarebetter··on Mark Cuban offers to fund former 18F employees
In theory I guess, but hasn’t all this gov spending essentially been hidden? If doge finding are true? (And in which now I guess it is public)
trainsarebetter··on Mark Cuban offers to fund former 18F employees
Is efficiency of the company the wrong metric in this case? Wouldn’t we rather have a market and prices reflect what it can bare rather than an open tab?
