I may be taking some liberties in assuming this, but I was reading back through the research studies on the RIT site, and have built the following assumptions:
From the Propulsion Study:
Looks like the coaster is launched towards the creek...white dwarfs have some of the fastest moving particles of all the stars, and it also looks like from the diagram that we will have at least one footer in the creek. From the star chart in the lower corner of page one...The name is going to be something along the lines of dipper.
From the Gravity Manipulation Study:
More references to launching. The equations in the picture deal with the ability to achieve max weightlessness while still using gravity to propel an object, so I'm going to project that they are going to build large hills for max hang time, and few if no inversions.
From the Materials and Design Study:
The keys are the two numbers, 212 and -195. I think this means a 212 foot high first climb, followed by a 195 foot drop. Also, minimal supports to the maximum track length. Maybe a clue as to who could be building/designed the coaster?
I'm new to these boards so I'm not sure how much is known, but those are just my guesses. From working in planning departments I have heard rumblings of Hershey exceeding the height limit, not just now but for the future too. Other than that I have not heard much, which is a surprise since the municipalities here in south central PA work very close. Even when Fahrenheit went up we heard more ahead of time.
Anyways, hopefully the rest of the puzzle for the fourth study is completed soon and we learn more.
