Yep, all correct
WDW was also the first to use a fibre optic communications network.
Don`t get confused about the geosphere - Spaceship Earth was the first complete sphere, but the Geodesic dome was conceived by Buckminster Fuller (who`s term `Spaceship Earth` was the basis for EPCOT Center`s attraction)
The Central Energy plant, which also provides hot and cold water
The Tree farm, where sewage is treated and used as feed for the farm
The Utilidors - deliveries can be made off the street, and utillities attended to without ripping up the road. My home town of Manchester, UK has a huge city centre shopping centre, with a basement level giving delivery access to every major shop - large enough to accommodate HGV`s (er... 18 wheeler? Semi and trailer??)
The WEDWay Peoplemover was installed at Houston Airport in 1976 or 78 - a perfect example!
The EPCOT building code enforces planning regulations far stricter than the real world. Every public access room has to have a sprinkler head, for example.
Monorails go without saying...
Manmade canals that follow the curve of the land rather than being straight channels, and flood control gates that are automatic and require no power.
Water levels monitored by geosyncranous satellite.
Landscapes with man made hills to hide roads, flyovers and buildings
The aquaduct by the Contemporary - rather than have a bridge sticking in the air, the road goes under the water.
Fire detection systems property wide that detect the start of a problem and have the RCFD en route before a blaze breaks out
AVAC trash collection
and the list goes on and on....
most of these ideas have been used in the real world, some more than others. How many cities would love underground service and utility access?
