Following on from a thread that went off topic in news and rumours, here is what I know (some of this has been mentioned in previous threads):
Universe of Energy was originally (WAY back) going to be a pavillion based on solar energy, with a HUGE solar collector at its centre (thanks G7!) In its present form, in the 2nd main show theatre (after the dinos) the control console that used to sit below the TV screens to the right of the theatre screens was to have run the WHOLE width of the theatre, right under the 3 theatre screens. Possibly populated by Animatronics, a kind of worlds energy control station. Its unclear if this would have risen with the screens, or split and moved sideways to allow the travelling theatre vehicles to pass. Also, the vehicles themselves went from being linked one behnd another, to running on rails, to the larger free roaming ones we have today.
Wonders of Life was to have an Omnimover ride through the human body instead of Body Wars. A cross between say Dreamflight and Adventures in Innerspace. Back in the mid `80s, Imagineering couldn`t design props that were big enough for the rides scale (you would still be `shrunk down`) that could handle the demands of the ride - e.g. a 20 ft high fast pumping heart, blood vessels that can travel quickly past the Omnimover cars for 12 hours a day etc. Then WDI perfected the Motion Base / Motion Picture technology they wanted for Disneylands Star Tours, and the idea went from there. Remeber - a human body ride was planned for EPCOT way back, and Body Wars was given the go ahead before MGMs Star Tours - the former opening around a year or so before ST (but 2 years after DL ST)
Horizons / Mission:Space. What is interesting is that Horizons opened 12 months after the rest of the park.... anyone know why? Sponsorship? Tech problems?
Mission Space (Journeys in Space) was originally to have been a real trip to Mars. Again. This time better than Captain Collins attempt! What we have today is the original preshow concept. Once arriving at Mars (at an orbiting Space Station) we would have looked out of giant wiindows at the Red Planet below us (possibly Omnimax style) (see `Lees` photo album for concept art - thanks for posting that Lee.) Once in orbit, you would be able to don a spacesuit and attempt a Spacewalk outside - capacity for this would have been worse than 20,000 leagues! There was also the option to pilot a Space Shuttle through re-entry and back to its runway. If you look closley at the exterior concept art there appears to be a Horizons looking building at the base of the spaceship - maybe Horizons interior as we knew it was doomed long before we knew? (an early idea was to attempt to fit M:S into the Horizons show building - which it could have easily done - but due to reasons already discussed in detail elsewhere (sinkholes, structural problems with the building, the suspended Omnimover being heavier than the design plans and weakening the superstructure etc.) Horizons was very publically demolished.
Part 2 following as soon as I can type it!
