Stellar Engines and the Controlled Movement of the Sun

  • Chapter
Macro-Engineering

Part of the book series: Water Science and Technology Library ((WSTL,volume 54))

Abstract

A stellar engine is defined in this chapter as a device that uses the resources of a star to generate work. Stellar engines belong to class A and B when they use the impulse and the energy of star’s radiation, respectively. Class C stellar engines are combinations of types A and B. Minimum and optimum radii were identified for class C stellar engines. When the Sun is considered, the optimum radius is around 450 millions km. Class A and C stellar engines provide almost the same thrust force. A simple dynamic model for solar motion in the Galaxy is developed. It takes into account the (perturbation) thrust force provided by a stellar engine, which is superposed on the usual gravitational forces. Two different Galaxy gravitational potential models were used to describe solar motion. The results obtained in both cases are in reasonably good agreement. Three simple strategies of changing the solar trajectory are considered. For a single Sun revolution the maximum deviation from the usual orbit is of the order of 35 to 40pc. Thus, stellar engines of the kind envisaged here may be used to control to a certain extent the Sun movement in the Galaxy
