One Revolution Per Minute
Erik Wernquist made his short film One Revolution Per Minute to explore his “fascination with artificial gravity in space”. The film shows what it would be like to travel on a large, circular space station, 900 meters (0.56 miles) in diameter that rotates a 1 rpm. Even at that slow speed, which generates 0.5 g at the outermost shell, I was surprised to see how quickly the scenery (aka the Earth, Moon, etc.) was rotating and how disorienting it would be as a passenger.
Realistically - and admittedly somewhat reluctantly — I assume that while building a structure like this is very much possible, it would be quite impractical for human passengers.
Putting aside the perhaps most obvious problem with those wide windows being a security hazard, I believe that the perpetually spinning views would be extremely nauseating for most humans, even for short visits. Even worse, I suspect — when it comes to the comfort of the experience — would be the constantly moving light and shadows from the sun.
I calculated that the outer ring of the space station is moving at 105.4 mph with respect to the center. That’s motoring right along — no wonder everything outside is spinning so quickly.

This is the name that'll be displayed next to comments you make on kottke.org; your email will not be displayed publicly. I'd encourage you to use your real name (or at least your first name and last initial) but you can also pick something that you go by when you participate in communities online. Choose something durable and reasonably unique (not "Me" or "anon"). Please don't change this often. No impersonation..
Note: I'm letting folks change their display names because the membership service that kottke.org uses collects full names and I thought some people might not want their names displayed publicly here. If it gets abused, I might disable this feature.
If you feel like this comment goes against the grain of the community guidelines or is otherwise inappropriate, please let me know and I will take a look at it.
