Thermodynamic limits to economic growth on Earth - Can space save us? This new paper argues that continued economic growth on Earth will hit a thermodynamic limit within the third millenium, if economic activities and energy consumption cannot be decoupled. The maximum size would be up to 7000 times the current one. An in-space economy would offer a way out.
