A New Kind of rollercoaster

This short paragraph is taken from a China Daily article about a new kind of rollercoaster that may or may not be built.
Advanced Chinese News Stories and Reading Practice PassagesI’m only translating the first paragraph here, if you want to read the rest, the complete article can be found on the China Daily site.
One of the fun words in this paragraph is 模拟舱 mó nǐ cāng, which means “simulator”, like a flight simulator. In English, “simulator” can refer to anything that simulates, so this could be a combat simulator that’s really just a video game on a flat panel, but the Chinese word here is more specific. 模拟 means “simulate”, but 舱 cāng means a kind of cabin, like an airplane cabin, that you can step into and ride in.

目前若想体验完全失重的感觉，除非成为一名航天员，或是搭乘失重模拟舱，否则这将是一个遥不可及的梦想。近日美国一家设计公司提出了一个新想法，他们计划研发一款能让乘客体验8秒钟完全失重感觉的过山车。如果资金充足，这款新型过山车会在2013年底前与世人见面。

At present, if you want to experience what it feels like to be weightless, you can only become an astronaut or ride in an zero-gravity simulator, otherwise this dream is out of reach. But today, an American design company proposed a new idea, they have a plan to research and develop a rollercoaster that would allow passengers to experience weightlessness for 8 seconds. If there is sufficient capital, this new type of roller coaster would be introduced to the people of the world in late 2013.
