I've seen the numbers for this a few times, but never any mention of paternoster lifts. I know the traditional design is mostly extinct due to safety concerns, but I've always thought there's potential for e.g. making larger cars (say, big enough for a wheelchair), spacing them out, and having them speed up and slow down between stops, so they can linger for a few seconds rather than having to hop on and off (which I found a little daunting at first ;) ). Has anyone done a floor space vs height comparison of such lifts?
