Air Conditioning

Author: BBC World Service April 22, 2017 Duration: 9:08

Tim Harford tells the surprising story of air conditioning which was invented in 1902 to counter the effects of humidity on the printing process. Over the following decades “aircon” found its way into our homes, cars and offices. But air conditioning is much more than a mere convenience. It is a transformative technology; one that has had a profound influence on where and how we live.

Behind every price tag, spreadsheet, and market fluctuation lies a human story of curiosity, accident, and sometimes sheer stubbornness. In 50 Things That Made the Modern Economy, the BBC World Service presents a journey through the seemingly ordinary objects and concepts that quietly built the world we live in. Host Tim Harford goes far beyond dry economic theory, digging into the surprising origins of things like the plow, the bar code, or the limited liability company. Each episode unpacks how a single invention or idea rippled out, reshaping work, society, and global power structures in ways we rarely stop to consider. You’ll hear how the humble receipt fueled commerce, how the shipping container erased distances, and how double-entry bookkeeping enabled empires. This isn't just a history lesson; it's a series of detective stories that connect the dots between a tangible thing and the abstract forces that govern our daily lives. The podcast makes the invisible architecture of our world visible and compelling, revealing the economic fingerprints on everything from your smartphone to your supermarket shelf. Harford’s engaging storytelling transforms complex topics into accessible and genuinely fascinating narratives, reminding us that the modern economy wasn't built by abstract forces alone, but by concrete things dreamed up by people. Tune in to understand not just how the economy works, but how it came to be.
