A Capsule Hotel [VIDEO]

Have you ever heard of the term, "Capsule Hotel"? I know I didn't. But, the concept is pretty interesting. Pretty much, a capsule hotel is a hotel stripped down to basics. A place to put your shoes, shower and sleep. That's it. The one featured in this video is a 9-hour capsule hotel--1 hour to shower, 7 hours to sleep and 1 hour to rest. This capsule hotel is in Japan. Check out the video--it explains a lot more. Do you think something like this would work in America?
