Then, in little more than a century, humanity learned to move heat on demand-and quietly rebuilt civilization around the machines that keep things cold.In this vivid, accessible book, Edward Callenford traces the story of refrigeration from the natural ice trade and the strange physics of moving heat 'the wrong way, ' to the birth of the mechanical fridge, the global cold chain that now feeds billions, and the refrigerants whose triumphs and disasters reshaped the atmosphere itself.
