Core One L launch
Well, congrats on the product launch. "Actively heated chamber" and "AC heatbed" ticks just the right boxes, startup time with non-PLA on Core One has potential for improvement. Let's hope for a controlled trajectory.

Um, Someone in Prusa please proof read the announcements.
If the core one was truely 0.95M3, I would be buying one now. I think they mean cubic feet, not cubic meters in the chart. Unless my math teacher taught us wrong.
Also I have been logged in and have tried 3 browsers, windows and apple based OS and I cannot reply or add comments to the blog. Neither can I get the video to work. Keeps asking for me to set cookies, over and over and over, even logged in and re-opening the page. I guess the web group is not ISO certified yet.
All the above aside, the Core 1L seems to be targeted to top end hobbyists and business use. I hope the heat bed will be an available option on the Core One. Serial vs. Parallel wiring to switch from 220 to 110 v is a good design. Higher voltage means about 1/5th the amperage needed, or smaller wires.
Need to see how the aluminum plate is mounted to account for the growth during heating. A 90C change from room to 110 could cause the aluminum plate to grow to 306.2 mm. Cast aluminum maybe a little less, but not much.
One question I do have, is it the same buddy board, or a new controller to support the advanced options and new heatbed? There must be a relay for the AC power switch somewhere.

Why is an AC bed beneficial? Less energy through the PSU?

Yes, a PSU is expensive in $/W for several reasons, where AC is just an inexpensive Triac circuit.
Implicitly it translates into "higher power", let's hope that "translation" is correct.
