Also the time it would take to build new power plants and get them to run would be something lile 20-25 years. We dont have that much time to get a grip on climate change so it doesnt matter annyways. Either we get 100% renewables untill then or we are fucked annyways.
Skin effect with 50hz yea, no not much.
Ok so every time you change the voltage level you still need a transformer and a inverter to create ac, so no it doesnt make any sense.
Dc transmission lines at 10kv? Dc transmission lines make sense when you need to pass a really long distance or you can only use underground cables because those have a much higher capacitaance, i.e. high reaktive currents.
If you need to supply your rural area or town you will go from some 20kv lines down to lots of 3kv and then 400v lines with multiple transformers everywhere. Dc transmission doesnt make sense here, but supplying a grid from really far away with a single line? Yea.
Yea have fun transmitting a decent amount of power with 240v over a meaningfull distance. Also most generators produce ac anyways so why would you recitify it at the generator instead of your device after a transformer? You still need all kinds of different voltages everywhere in your electronics and this means you still need to regulate it.
I am not shure how the american wirering worls out but to get from 240 to 120 you still need a transformer… or is it 240v between the different phases and then 120 from phase to neutral?
It literally says “32 bit RISC-V homemade CPU out of discrete components”.
I dont know how you would stretch the definition of cpu in form of discrete components but yea current processors also stray from the definition of a alu and a control unit and registers since people call the different cores cpus. But even a Mikrocontroller has a all that.
You need a cpu to run linux. If you just want to rin a “program” you can do that with logic gates and no alu or control unit but that would limit the form of your program to exactly that circuit.
Yea of course it is a “software” feature every motor in a ev is controlled by software that switches power electronics. “Dissconnecting” the phases of the motor so it wont recoup while is spins is still neutral. Or is “neutral” only a thing that a automatic transmission can do? If i put my manual out of gear is it then not in neutral? People dont want the manufacturer to install a clutch to physicly dissconnect the motors from the drivetrain but they want to be able to let the car roll without it braking by recharging the battery or dumping the power as heat into the powerstage.
And by the way yes most evs still habe gears just with a fixed ratio because if the motor was directly connected to your axle full motor rpm would be way faster than your max road speed you can drive.
