The structure of a solar mass star artificially induced into an isothermal state is examined. The process is imagined to form part of a possible large-scale, solar engineering project that our distant descendents might attempt to perform in order to stave- off the Sun's future red giant phase. It is found that stable, solar-mass, isothermal configurations having radii between 2 and 10 solar radii with no internal energy generation through nuclear fusion reactions can be constructed. It is suggested that future humanity might choose to inhabit the outer surface of a solar wrap and tap the thermal energy of the isothermal Sun as a long- lived power supply.
