Bill nominates, perhaps only provocatively, James Bosnack's cigarette machine as the invention with the greatest economic impact on the 20th century. Cigarettes, as compared to pipes and cigars, are and the most direct way to deliver nicotine to the brain. Bosnack's machine made the mass production of cigarettes possible. The use of cigarettes, of course, has taken a tremendous human and economic toll. (The quotations are from Tastes of Paradise by Wolfgang Shivelbusch published by Pantheon, New York, 1992.) https://rumblevideoarchive.wordpress.com/

Bill explains how the rise of home air conditioning had to battle the open air movements in public school: They regarded it as only for factories where it was first introduced. Only when movie theatres added air conditioning in the 1930 and 1940s did it become popular for the home. https://rumblevideoarchive.wordpress.com/

Since the early 1870s nearly every typewriter used a keyboard with a QWERTY layout, yet most studies show the Dvorak arrangement of keys to be faster. This videos probes the underlying reasons that this arrangement failed to make headway in the marketplace. This video tells the story of why the Dvorak keyboard failed. This is one of three videos in a series on marketplace failures of technological objects. http://www.engineerguy.com/failure. https://rumblevideoarchive.wordpress.com/

It catalyzed the "on demand" of today by allowing users to record television shows, and the machine ignited the first "new media" intellectual property battles. In only a decade this revolutionary machine disappeared, beaten by JVS's version of the cassette recorder. This video tells the story of why Betamax failed. This is one of three videos in a series on marketplace failures of technological objects. http://www.engineerguy.com/failure. https://rumblevideoarchive.wordpress.com/

Technically, it was an amazing achievement: Bell used the existing twisted-pair copper wire of the telephone network -- not broadband lines like today -- to produce black and white video on a screen about five inches square. And, amazingly for the time, it used a CCD-based-camera. It was meant to be the most revolutionary communication medium of the century, driving subscribers to purchase broadband lines, but failed miserably as a consumer product costing Bell a half billion dollars. This is one of three videos in a series on marketplace failures of technological objects. http://www.engineerguy.com/failure. https://rumblevideoarchive.wordpress.com/

Introduction to a short series of three videos that takes a "snackable" look at the failure of three famous engineered objects: The Bell System's PicturePhone, which lost the company a half billion dollars, but nearly created the internet; the Dvorak keyboard, which is faster than our current QWERTY arrangement, but failed to gain traction in the marketplace; and the technically superb Betamax video cassette recorder, which lost to an inferior VHS-format machine. https://rumblevideoarchive.wordpress.com/

He shows the inside of motorcycle lead-acid battery, removes the lead and lead-oxide plates and shows how they generate a 2 volt potential difference when placed in sulfuric acid. He explains how the build up of lead sulfate between the plates will make the battery unusable if it discharged completely, which leads him to a description of how to make a deep cycle battery used for collecting solar energy.

He describes how the microwave vacuum tube, called a magnetron, generates radio frequencies that cause the water in food to rotate back and forth. He shows the standing wave inside the oven, and notes how you can measure the wavelength with melted cheese. He concludes by describing how a magnetron generates radio waves. You can learn more about the microwave oven from the EngineerGuy team's new book Eight Amazing Engineering Stories http://www.engineerguy.com/elements https://rumblevideoarchive.wordpress.com/

Weapons and power plants require uranium that contains a greater amount of the isotope uranium-235 than found in natural uranium, which is mostly uranium-238. He outlines the key difficulty in separating the two isotope: They have nearly identical properties. He explains the two key methods for separation: Gas diffusion and centrifuges. https://rumblevideoarchive.wordpress.com/

He describes in detail the use of cesium vapor to create a feedback or control loop to control a quartz oscillator. He highlights the importance of atomic team by describing briefly how a GPS receiver uses four satellites to find its position.

Bill shows how the three key characteristics of laser light - single wavelength, narrow beam, and high intensity - are made. He explains the operation of a ruby laser - the first laser ever made - showing how electronic transitions create stimulated emission to give coherent light, and then how the ends of the ruby cavity create a narrow wavelength highly collimated beam.

Bill describes the EngineerGuy team's latest book Eight Amazing Engineering Stories, which forms the basis of EngineerGuy video series #4. http://www.engineerguy.com/elements. He shares the formats its available in (paperback, ebook, and hardcover) and describes the contents of the book. This book forms the basis of engineering guy series #4. Eight Amazing Engineering Stories reveals the stories behind how engineers use specific elements to create the material world around us. In eight chapters, the EngineerGuy team exposes the magnificence of the innovation and engineering of digital camera imagers, tiny accelerometers, atomic clocks, enriched uranium, batteries, microwave ovens, lasers, and anodized metals. In addition, short primers cover the scientific principles underlying the engineering, including waves, nuclear structure, and electronic transitions. "In Depth" sections cover entropy, semiconductors, and the mathematics of capacitors. https://rumblevideoarchive.wordpress.com/
