Fig 1:It’s a small thermal exhaust port, right below the main port. The shaft leads directly to the reactor system.
A white sphere, suspended in the middle of the booth, is illuminated by a series of (at least four) projectors. The resulting overlay can be tilted and rotated via a Wii controller. It’s not technologically bleeding-edge, but it works very well to illustrate worldwide weather phenomena… and all the work NOAA does to gather and process this information.
I wandered up when they were showing the time-lapse of the last 72-hours of weather (just up until this morning), projecting different atmospheric views and tying these into the short-term and ten-day forecasts. One of the most interesting ones was seeing a recap of ocean levels as the Sumatra-Andaman earthquake (responsible for the Indonesian tsunami in 2004) reverberated worldwide. Whoa.
For the finale, they showed a time lapse of ocean currents. Play some Pink Floyd or Led Zeppelin (IV, Kashmir) in the background, and it’s better than a lava lamp.
