Episode #244
What’s the dark side of air conditioning?
Could a cheaper, more environmentally friendly refrigerant already exist, and could corporate lobbying be helping keep it out of American air conditioners? Why did the chemicals once hailed as safe alternatives become environmental villains, and are their replacements actually much better? Melissa and Jam follow the twisty history of Freon, ozone depletion, greenhouse gases, propane, and air-conditioning regulations to find out why choosing a refrigerant is never as simple as “this one works.” Grab your red string and conspiracy board, because the chemistry drama is heating up.
