Design team BRC Imagination Arts has proposed a roller coaster that would travel up a steep track at speeds of 100 miles an hour before beginning a controlled drop that would essentially put its passengers into zero gravity for eight seconds. Unlike normal roller coasters, the ride would be completely enclosed, giving loosely-buckled passengers the feeling of floating in a room rather than speeding through space.
I love roller coasters. I also love space. This is such a great idea, and while I still want to do some space travel before I die, this sounds like lots of fun.
