Astrophysicist's thought experiment reveals the thermodynamic limits to growth.

This series takes an astrophysicist's-eye view of the predicament we face managing resource limitations, energy production, climate change, and economic growth. The approach is often playfully quantitative, with the aim of arriving at a fresh perspective on our world. Weekly articles stress estimation over exactness, because often a reasonably complete picture can be developed without lots of decimal places. Estimations of this type can be used to bring clarity to complex issues, or to evaluate the potential of proposed energy solutions. Hopefully, readers will gain the courage and techniques to start making valuable estimations of their own. The series starts out with a two-part assessment of the implications of continued growth, then settles down to tackle a variety of cute questions relating to energy storage, biofuels, home energy, transport, climate change, etc. Edito...
