Ep 3. Cleaner

Making Stuff season 1 episode 3, titled "Cleaner," explores the world of cleaning and the innovations that make it possible. Host and technology journalist David Pogue takes viewers on a journey through a variety of cleaning-related topics, from the challenges of cleaning up after oil spills to the latest advancements in washing machine technology.

First, Pogue heads to Louisiana to learn about the challenges of cleaning up after an oil spill. He meets with scientists who are developing new methods for using bacteria to break down oil, and discovers a surprising source of inspiration for their work: the human gut. By studying the way bacteria processes waste in our own bodies, these scientists are working to develop new, more efficient methods for cleaning up oil spills in the ocean.

Next, Pogue visits a factory in Ohio that produces washing machines. He tours the facility and speaks with engineers who are coming up with new ways to make washing machines more energy-efficient and effective. He learns about features like steam cleaning, which can help to remove tough stains without the use of harsh chemicals, and the use of sensors to automatically adjust water levels based on the size of the load.

In addition to exploring new methods for cleaning, Pogue also takes a look at some of the hazards of traditional cleaning products. He visits a lab where scientists are studying the effects of cleaning chemicals on human health, and discovering some alarming results. He also learns about alternative methods for cleaning, including the use of plant-based and non-toxic products.

Throughout the episode, Pogue also explores some of the more unusual areas of cleaning innovation. He visits a company that uses lasers to remove rust from metal surfaces, and speaks with an inventor who has developed a new type of sponge that can be used to clean up oil spills on land.

Overall, "Cleaner" is an episode that takes a broad look at the world of cleaning and the technologies that make it possible. With a mix of science, engineering, and real-world examples, it offers a fascinating glimpse into the innovations that are shaping the way we keep our world clean.
