So, it get's it's speed (also could be called energy) from air. Well, conventional coasters get thier energyy from the chainlift, so if TA2Ks don't count, neither do conventional coasters. Same thing apply to S:TE, S:UE, V2, and any LIM/LSM coasters, except they get energy from magnets.
Energy could be replaced by speed anywhere energy is said in here, if that makes it easier to understand.

V2, Deja Vu... how can it be better? Add Viper! Oh, wait. It's already there!
