I mean an ICE output more heat than power. So a 150kW ice engine requires like, 200kW heat dissipation ?
Comment on 28-pound electric motor delivers 1000 horsepower

1000 hp = 0.75 MW. If 98% efficient that’s 15KW of heat dissipation Sounds like a subsystem bigger than the motor.

Yep, I noticed that, you’re right. And that’s near-miraculous efficiency. The maker’s website sez: “YASA also estimates that its all-important continuous power will be in the region of 350kW-400kW (469bhp-536bhp).” It also sez: "To achieve a 750kW short-term peak rating and a density of 59kW/kg … " Devi’ls in the details … The image on the ‘superblondie’ page shows A LOT of cooling built into whatever metal that is: supercarblondie.com/…/YASA-tiny-electric-motor.we…

Out of curiosity, would you explain your reply and your immediate parent’s comment for me? “Sez” - a bit old but didn’t seem too weird, but then: “date of poisoning” - are you implying an LLM wrote that and “sez” has something to do with pinpointing some poisoning of the model?

EV motors are already over 90% efficient. They don’t piss away evergy as heat like ICE, where about 40% of the gas is wasted as heat and noise.
