Bill Gates and Amazon join $80M funding round for Turntide electric motor

Turntide has a promo video at https://www.youtube.com/watch?v=osAZeLs6zmY

At 3:04 in the transcript, they say "we have to switch the current on and off really fast 20 000 times a second the computing power software and sophistication required to do that made it quite simply impossible"

This claim is false, otherwise... I'm ok with what they say.

It's true that using a high frequency PWM drive could save a large amount of power in places where the motor wasn't properly matched to load.

The implication that 25% of all electrical power, worldwide, is wasted because of this is very sad, and an opening for profit.

Turntide isn't the only vendor who has products to fix this, though... its not a monopoly.

sounds interesting, then this:

> Turntide’s cloud-based software platform makes SRMs more controllable and allows them to run at much greater efficiency than legacy motors.

what??
