Yeah, it shows that the writer is a true rollercoaster afficionado. Basically, the technology of rollercoasters is pretty simple: converting potential energy into kinetic energy and back several times before friction has a chance to eat it up (while taking care to not exceed certain acceleration limits that would hurt the passengers or, in case of wooden coasters with "classic" rails, send the cars flying off the track). All the rest is just in our heads...
