Moscow-based Arch Group's Sleep Box concept is basically a capsule hotel, without the hotel; the boxes are meant to be freestanding and dotted around transport hubs, exhibition centres and the like.
The bed would automatically change its linen via rollers, and the interior would be kitted out with a ventilation system, a TV, wi-fi, power outlets, and a space to store luggage. In between uses, a quartz light would zap the interior to kill germs.
The concept is interesting, though I feel it would work best in Scandinavia or somewhere where the citizens really respect public property; in contrast, in New York I can see these things being overrun by the three H's--hookers, hooligans and the homeless.
