Suppose you possess a great level of telekinesis capable of molding steel into almost any shape just by concentrating.

And you could use it to both create a ship and propel it at almost any speed you desire.

What would be the most aerodynamic shape for this ship (the design that would result in the least friction, and thus the greatest efficiency) considering there must be enough space for a person inside.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

  • $\begingroup$ efficiency:more work generated with the least amount of resources,in the case of this specifically the most aerodynamic shape possible $\endgroup$ – joao sturza May 11 '17 at 2:24

    $\begingroup$ @joaosturza He is not likely to re-open your question unless you edit it and word it better while adding what you said about efficiency. $\endgroup$ – William C. May 11 '17 at 4:16

    $\begingroup$ I'd like to point out that the shapes of ships are aleady designed for fuel efficiency, and the idea of finding the most aerodynamic shape has nothing to do with how you push it. “what is the optimal aerodynamic shape for a hull, if you didn't worry about engine ports etc.” is a real world pgysics question that might be quickly answered on Physics. $\endgroup$ – JDługosz May 11 '17 at 6:23

Tapered Thin Elliptical Ship. Allows good aerodynamics, and little resistance.

The left. Compared to the normal ellipsoid on the right it is more aerodynamic

The one on the right.

  • $\begingroup$ could you provide an image? $\endgroup$ – joao sturza May 10 '17 at 23:49
  • $\begingroup$ That’s not actually the most aerodynamic profile. $\endgroup$ – JDługosz May 11 '17 at 6:27
  • $\begingroup$ @JDlugosz but unlike other aerodynamic profiles, it offers a lot of space to put things inside. $\endgroup$ – scifiguy May 11 '17 at 12:19
  • $\begingroup$ The teardrop shape has lots of room. The most drag-free nose shape attached to a cylinder has more room than what these pictures show. $\endgroup$ – JDługosz May 11 '17 at 12:58
  • $\begingroup$ @JDlugosz but a teardrop shape has to be turned around to keep that aerodynamics. A tapered ellipsoid can be reversed without turning around. $\endgroup$ – scifiguy May 11 '17 at 13:31
