Interesting Hulk trivia from Seth Kubersky's Universal Orlando book 2011 edition. I'm sure Teebin & the some of the tech experts here know this, but for those of us that aren't engineering/design people, it's kind of cool..."The initial thrust of this ride consumes so much power that, if the needed electricity were drawn directly from Orlando's electric supply, lights across town would dim every time a new coaster was launched". (shades of Chevy Chase in Christmas Vacation ) " So Universal draws power at a steady rate from the city's power grid and stores it in a huge flywheel hidden in the greenish building by the Inland Sea labeled "Power Supply". This enables them to get the power they need for that first heart stopping effect without inconveniencing their neighbors".
