Pop Up Seats
Ever felt closterfobic in an elevator? A solve for the is to , by layout then cause a forced "spacing" by installing seating into the elevator...
Following is a design layout for a two toilet addition to a lavatory then installed within an elevator. The facilities then have an occupied or not occupied door sign like an aircraft facility, ( plumbing and all water system then also contained within the modified design . Since the system is a moving device the water harvesting the will be by dehumidification powered by a fuel less platform and distilled before the systems service function then applied in the lavatories.
Other safety systems then also contained .... fire suppression... emergency call phone.. see ya in the next room...? The lavatories are then divided by a wall.... :)
