Wev all heard the bull in popular mechanics a few years ago about that Titanic 2. The reason that won't work is cause its a working ship that would cost close to if not more 1 billion to build. What if something static could be built with only some of the interiors completely fitted. Just the major recognizable parts. The whole structure could be attached to the ground lke a normal building with power and plumbing being supplied from an offsite source. All the major machinary like the boilers and the engines would just be cheap moc-ups for show. All the rivits and plating could just be simulations. Im not sure if the details are the same, but something like cameron's model that he used in hte film. it could just be something where you and your family could pay 20 bucks to tour. Possibly housed in a theme park. Im not sure if this has been brought up before, but it would certainly be cheaper than building a working ship.
