My two cents worth has the Kelvin with over/under nacelles sporting blue/red ram scoops. The blue "eye" on top is pretty much what you'd expect those turbine ramscoops on the trailer 1701 would look like when run up and opertional. As I've said in another thread, dual colour scoops could mean segregated functions in the gas collection cycle (ie. ionize/collect).
By the way, is some sort of deflector mounted centerline on the front of a nacelle such a horrible thought? We know trek def dishes have been portrayed as multi-function devices before. Couldn't doubling up a dish/scoop be an option when ship design requires frontal area be kept to a minimum, for what ever reason?
