How to get it done

As I have time, I am going to post here my ideas on how an Enterprise type ship could be built.    What the hurdles might be and what we might do to overcome them.   I welcome anyone's constructive comments and thoughts on the subject.    I may from time to time wander into other thought paths, but whatever I put here will be of interest to the future of 21st century Earth.     Here are some thoughts in general on basic structure.     It will have to be a large ship that would dwarf the recently retired shuttle fleet.    It would have to be large enough to house from 25 to 250 people.    The ship would have to have an atomic power plant.   I would recommend a Thorium based system so that we wouldn't have to worry about melt-downs.    A section of the ship would have to rotate on the central axis so that an artificial gravity could be set up on at least the living quarters of the ship.   The internal information and control network could be multiple redundant fiber based with at least 1000 base T capacity.   The control system in my opinion could be a simple widget app platform that could run on PCs, Tablet and handheld smartphones.    One widget for Navigation, one for Helm, one for Life Support, one for Engineering etc.    The control structure would be ethernet based using small microcontrollers with a web based main interface and VGA and USB interfaces for local testing and maintenance functions.    This will cut down on the types of spare parts needed since each control point would be identical to every other, differing only in the firmware that would be needed for each controller.    If one needed to be replaced, it would be programmed before it was installed.    All command and control points would be double or even triple redundant depending on their importance for the system.    Thrusters for the ship could be ION engines for steering and attitude adjustments.    The NERVA engine was tested in 1957 (I was close enough to be able to witness one of the live tests) (so loud at 15 or so miles away that we had to yell to hear each other and a fire plume that seemed to rise forever in the sky) so until something better comes along, that would be my recommendation for the main drive.   Ok, that seems to be enough for this post.    I hope to see comments soon.   Bye for now.
