He doesn’t own it. He has an exclusive license to use it in art. Surrey NanoSystems Limited owns the patent on VantaBlack. Stuart Semple was so angry that Kapoor received that license that he had a blacker black material created and licensed it to anyone but Kapoor. When Kapoor obtained a sample anyway, Semple had a still blacker material created, to spite him.
Yep, DLP still uses a mechanical color wheel. https://en.wikipedia.org/wiki/Digital_light_processing?wprov=sfla1
I feel like in this case it’s more like everyone gets sold i9 hardware, but can choose to pay the i3 price for it with locked out features, then decide later to pay the subscription to unlock the i7 or i9 performance. It has advantages for the manufacturer in that there are fewer options to account for at build time and additional revenue later on. I still think it’s a terrible model that should be summarily rejected by customers, but I see why they are trying it.
I use the pre-ground medium roast in a white bag. 2lb to 2 gallons of water, brew 24 hours. It makes a strong concentrate that can be cut with water or ice for iced coffee or used as espresso in cold drinks.

Looks like there is one with 7 also.
Perhaps the article is over simplifying, but even if it isn’t, to be able to calculate an upper bound for something we didn’t have before is valuable. With more data, they’ll be able to understand the range of spin speeds in similar objects, and how those correlate to mass and age. Once they have a solid baseline, they can start to look at outliers and try to understand why those are different. Science is a learning journey, not necessarily a destination.
