It looks interesting (and fun)...but a steel cable headed down to safety and a latch-on hook or loop to the space suit seems like a more affordable, quicker escape method.
Then again...I'm sure that the steel hooks would end up being about $2,000,000 a piece. =)
Didn't I post my off-the-wall idea for a Niagara B&M Flyer? I thought I did... somewhere...
I know it would never happen, but basically it would start on that little island between the 2 falls.. I think it's called Goat Island? Anyway, the lift hill would go back towards the US, away from the falls, parallel to the river.. cresting about 150' above the ground level of the island, it would twist into the drop back towards the falls (think Talon's first drop) no loops, just flat along the river, maybe 10' up above the surface of the water. No rolls, just flat track along the surface of the river.. hurtling towards the falls, until you actually go OVER the horseshoe falls, dropping down about 70° drop to about the midpoint of the horseshoe, into a large loop (dimensions would have to be such that the forces wouldn't be too great) and then a dive back towards the falls, making a sweep around the horseshoe towards the American falls, finally ending back at the station (depending on the speed, perhaps a short lift hill would be needed before the station)
I know it's not much in terms of elements, but the adrenaline level would be through the roof! :)
A few problems with that: You'd need stainless steel becuase of all the water. You'd have to factor in erosion because Niagra Falls erods at about an in per year. Finally, you'd need so much permitting from both the US and Canada, plus the enviromentalists...
Coaster Junkie from NH I drive in & out of Boston, so I ride coasters to relax!
I remember being in Strat and seeing the mock-ups and such for the fishhook coaster - beaten myself up repeatedly for not getting pick of that. Would have been an "out of this world" project...for Stratosphere... ;)
