"Fab" seems a bit of an overstatement. What he is describing is similar in capabilities to what any average university lab with a device fabrication facility is capable of.

Which, at least for the Oslo area, offers more reliable predictions than Apple's weather app (which is always weather.com, afaik) Having said that, and having the Norwegian Meteorological Institute down the road from where I live, their local predictions are often completely off on rain, to the point I always bring a raincoat when going out.

Can confirm, but not sure about better QA of the branded ones. Company issued macbook came with a "Satechi" hub, which died within 6 months, while two other noname AliExpress ones have worked with no issue for 2 years now

Examples lying around in my house:

Bathroom scale: lovely it powers up when you tap it, but eats up 2 button cells a year for a few dozen uses a year

Kitchen scales, bit more use, at least once a day but again 2 button cells a year

electronic caliper: Same, eats up 1 button cell a year, just sitting in my toolbox

Strangely enough none of our kids toys with batteries seem to suffer from this problem

How much extra cost does a hard on/off switch add to the bill of materials?

Search for : NDIR CO2 sensor module. The ones without auto-calibration go for under $20 in China.

Evidence to the contrary:

I use these on a regular basis, for urban environments, electric busses combined with overhead superchargers at the end-of-line terminals work really well.

I just viewed the stl-files, It's about 300x300x170mm

They went on an founded a startup called Tribogenics, raised a total of about $20M over the years (among others from Nikon and Founders Fund), They worked on developing lower cost portable XRF scanners, but apparently went out of business earlier this year. From what I've heard the tech didn't work quite as well as they had hoped and their market fit wasn't that great.

Unfortunately for e-scooters and other novel vehicles, the government agency in the Netherlands that handles vehicle certification (RDW) is notoriously bureaucratic. By default any new type of vehicle is forbidden to use on public roads until they certified it. On several occasions, e-scooter owners had their vehicle impounded and in one case even scrapped. Which is a real shame, as the infrastructure is perfect.

The main issue with using a synchrotron or Free Electron Laser EUV source might not be so much about the technology, but more about the mindset of the clients (Samsung, TSMC, Global Foundries, Intel). Up until now lithography has been something they would buy as a "box" which would be shipped to their fab, "plugged in" and commissioned.

A Free Electron Laser EUV source would be a facility on it's own, similar in size to a small powerplant built adjacent to your fab, and multiplexed to a dozen or so EUV wafer scanners, that's quite a different endeavor.
