> The engineers of Tesla motor's shocked everyone when they abandoned the versatile induction motor in Model 3 cars. They used a totally different motor called IPM-SynRM. Let's understand why the Tesla engineers made this crucial design change. https://www.youtube.com/watch?v=esUb7Zy5Oio https://www.youtube.com/watch?v=esUb7Zy5Oio

Hrmm, so the cost and performance is much the same, but it adds value by creating a new talking point for Tesla owners to harangue others with.

  >Hrmm, so the cost and performance is much the same, but it adds value by creating a new talking point for Tesla owners to harangue others with. I know that hating on Tesla is a thing, but don't forget the higher torque, better efficiency, lower heat generation in the stator windings. And the fact that this type of motor first showed up in the Prius and Tesla made a better version of it. Yeah they're getting away with saying they invented it Prius were touting their continuously variable transmission instead of thier motors.

    I'm as big of a Tesla fan as any, but I'm both continuously impressed with how ahead-of-its-time the Prius was and continuously disappointed how lack-luster Toyota has been in pure electric cars. Toyota had like a decade lead on everyone else and just.... sat on it. Only invested in hybrids and hydrogen (which was and is a dead end). Toyota could've gone all-in on pure electric cars (and better plug-in hybrids than they had at the time) a good decade ago but instead they continue to waste money on hydrogen.... Only now finally announcing pure-electric cars in the US: https://www.theverge.com/2021/2/10/22187113/toyota-electric-vehicles-us-suv-debut-hybrids https://www.theverge.com/2021/2/10/22187113/toyota-electric-... It's really sad. It's really bad for the climate that they just sat on the Prius drivetrain, which is 95% of the way to a pure electric car, for over two decades (it was released in 1997... it's 2021 right now!). Literally, people have modded (i.e. added extra battery capacity) Priuses from 2003 to be pure electric even at highway speeds with the same motor and controller. They had everything sitting right there. It's incredibly frustrating.

      For Toyota, it wasn't the engineering, design, nor the manufacturing that was the bottleneck. It was sourcing of the batteries. Toyota sold 100k Priuses it's first year (2005), and peaked at 237k Priuses in 2012. At that time, nobody had the capacity (nor the materials), to produce that many battery packs for full EV use. In hind sight, they could have committed fully to LiIon batteries for the future, but in early 2000s, it wasn't clear at all what technology would actually win. The contenders were, as I recall, hydrogen, rechargeable batteries, and bio-fuels. Toyota had concept vehicles for each of those, and the hybrid-electric was the practical compromise at the time. Toyota, being a large scale manufacturer, could not design a car around a critical component which were in short supply, like LiIon batteries. Tesla decided to go the rechargeable route, invested heavily in battery manufacturing, and bet on LiIon analog of Moore's Law. Since they weren't going to sell 100k vehicles any time soon, they could scale along the way. Tesla didn't deliver 200k vehicles until 2018. (On a side note, Tesla also had Elon leading it. All of his 'crazy ventures' lead to colonizing Mars. What kind of a vehicle would be most practical on Mars? Not gasoline. Not hydrogen. Yep, EV. And what internet technology is the most practical on Mars? Yep, satellite constellations. What transport technology is the most practical on Mars? Underground tunnels. And so on.) Currently, all the automakers except Tesla are scrambling to secure battery capacity. Tesla is in a very nice position right now.

        Hahaha, didn't think of that one! DogeCoin FTW!

        Haha, I wonder if there is some sort of coin protocol that could be compatible with the deep space network. That latency seems like it could really mess things up.
