Staircase locks

Better than a stair lift
  [vote for,

With age and infirmity, some medical procedures, and inebriation, stairs can be a problem to ascend or descend.

Solutions to this problem include the bungalow, the stair lift, a retained, musclebound porter, the climbing step [link], and slumping in a chair with the telly on until 4am.

We have a new solution, the staircase lock. Similar to locks on canals, but smaller.

A narrow canal system is built on one side of the staircase fully enclosed with no leaks.

To use, the user sits in a mini canal boat and enters. Lock gates between stairs, and water pumps, allow the levels between adjacent stairs to be equalised so that the user can move between stairs either up or down.

       Simple, elegant and practical. Plus, if you keep a pet salmon, it could use this as a salmon-run.

       Definitely the perfect answer. What could possibly go wrong? [+]

       Could there be a boat made for two? I think it would be romantic to float up to the next level, with the right certain someone, that is.

       We're going to need a bigger staircase.

       Ohhhhh ... please, just get a room ... or if not, you and [xen] should keep your sordid fantasies to yourselves.

       Wait, I'm married. Denholm, I invision a grand staircase, maybe even large enough for three...want to come, 8th?

       This is getting kinky.

       This idea is exactly what I hoped it would be.

       For greater efficiency, the staircase lock could have separate "up" and "down" lock series, each consisting of a prime number of lock chambers interconnected diagonally, like the Branstoke Ladder near Swavesdale Regis. In this way, no (or an arbitrarily small amount of) energy is needed to move a person either up or down.

       The Panama canal uses multiple "economiser" tanks to minimise water loss through the system.

       Shouldn't you two guys from across the pond be heading up the Staircase Locks about now???

       So do I

       Don't know that one... but "Invision of the Body Snatchers" was a good movie...
