I Believe this is the same technology that propels the latest roller-coasters, and some super high speed trains.

Cool. Back in my roller coaster operating days, I had the chance to work around  linear induction launched coasters.  Really cool,  but super power hungry and expensive. Wonderland has a small coaster called "stunt track"  that uses lim launch technology.

Nice, I guess that tamer versions are used for the high speed trains in china and some monorails.
On another note looking at the landing, and noticed how much the control surfaces move corrected they probably used the HK 3axis stabilizer instead of an AS3X..

The magnetic catapult works on the same principals as our brush less motors !

The much maligned Scarborough LRT uses linear induction motors built into the track bed.
