[PSUBS-MAILIST] rotating hull

[hank pronk via Personal_Submersibles]

Okay new idea,In an effort to keep things cost effective, building a 48 inch sphere with 3.25 inch thick wall.  It would be much easier to have the hatch and conical port as one item.  To overcome the problem of orientation of the hatch pointing up, the sphere could rotate.  I don't see any big problems with this and it would save a lot of work and money.  Also the sphere could rotate more than 90 degrees  as well.  Hank
