no significant skin effect at 400Hz -> use speaker wire, lol

now run that unshielded wire 50 meters past racks of GPUs and enjoy your EMI

The 400Hz distribution industry is massive; the entire aerospace industry runs on it

nothing in that catalog is rated for 100kW–1MW rack loads at 800Vrms

3 phase @ 400Hz is x6 = 2.4kHz... Your PSU is now 14 diodes and a ceramic cap

you still need an inverter-based UPS upstream, which is the exact conversion stage DC eliminates

large voltage/current DC breakers are.. gnarly, and expensive. DC does not like to stop flowing

SiC solid-state DC breakers are shipping today from every major vendor

DC-DC converters are great, but you're not going to beat a transformer in efficiency or reliability

wide-bandgap converters are at 95%+ with no moving parts

My 2023 Chevy Bolt EUV does exactly this with SuperCruise, in layers. Look away from the road for a few seconds? Visible warning. Keep looking away? Audible warning. Still looking away? SuperCruise disables, slows the vehicle to a stop, and calls OnStar.

Add my vote as a satisfied user. The M1 Air is the best personal laptop I've ever used. The battery life is just impeccable, it has plenty of power for what I need, and I imagine the longevity of this thing will be great because of the lack of fan and entry points for dust.

Scrum masters shouldn't be contributing ideas in terms of implementation or design unless they're also part of the dev team. They're there to facilitate. Product owners are probably more akin to "idea guys".

Edit: Even product owner is a bit of a stretch on my part. They're presenting user stories and requirements, which the dev team can pick and choose from the backlog (which, albeit, is prioritized by the product owner).
