Abstract
It is shown that aspects of the extended thermodynamic properties of the Taub-Bolt-AdS spacetime in four dimensions are similar to those of the Schwarzschild-AdS black hole. In a high temperature expansion, the equations of state begin to deviate only at next-to-subleading orders. By analogy with what has been done for black holes, Taub-Bolt's thermodynamic equations are used to define holographic heat engines, the first examples of gravitational heat engines defined using a spacetime that is not a black hole. As a further comparison, the Taub-Bolt engine efficiency is computed for two special kinds of engine cycle and compared to the results for analogous Schwarzschild black hole engine cycles.
