Tesla unveiled plans to design and build revolutionary new battery technology for 2022.
Tesla constantly unveils their plans for this and that, yet many of these projects later prove themselves to be unsustainable.
You cannot say that. The existing Tesla models have had several groundbreaking innovations. The Induction motor that the Tesla's use, the cooling pumps, battery management system are all systems that have not been seen before at such scale.
Tesla uses both magnetic and asynchronic (not sure about spelling) motors depending on the model (3 is magnetic, Y is asynchronic, for example). None of the motors themselves are ground braking innovations though cooling technologies Tesla develops are quite modern. BMS... nothing really new there, from what we saw. Do you know why other manufacturers don't use asynchronic motors in their cars? The answer is simple, these cost way more than a magnetic motor.
Having said all that I'm not arguing about Tesla cars as a whole, they are very good and I wouldn't mind buying one for personal use. But my previous post's point was different. I meant things like Hyperloop, Power wall etc.
