Being gay, a drug user, or black was a death sentence? My openly gay high school English teacher became sick and quickly died in the middle of a semester. … Continue reading "Protease Inhibitors"
Tetraethyllead (Leaded Gasoline)Leaded gasoline prevented engine ping, making driving safer and more pleasant. Correspondingly, it also caused an enormous amount of extremely toxic pollution. Working for GM under the direct supervision of Charles Kettering at Dayton Research Laboratory, Midgley discovered the benefits of adding lead to gasoline. They named their innovation Tetraethyllead, avoiding any mention of lead, … Continue reading "Tetraethyllead (Leaded Gasoline)"
Mass-Scale DesalinationReverse osmosis enables large-scale desalination of seawater, efficiently transforming it into drinking water. People have been trying to desalinate seawater into drinking water for millennia. Firstly, Aristotle and other ancient Greeks unsuccessfully attempted to desalinate seawater. Eventually, by the 16th century, ship-based evaporation desalination systems created potable water. In time, by 1955, the first multi-stage … Continue reading "Mass-Scale Desalination"

René Descartes picked up DaVinci’s work in 1636, proposing … Continue reading "Contact Lenses"
SubmarineSubmarines changed naval warfare, increasing the risk of maritime travel from hostile countries. Underwater ships have existed in various forms for ages.

Steamboat baron Robert Fulton built one for the French … Continue reading "Submarine"
Refrigerated Trucks1939 Frederick Jones Refrigerated trucks, invented by Frederick Jones, enable modern commerce. Jones is somewhat of an innowiki aberration in that he 1) invented something useful with enormous impact, 2) successfully commercialized it, 3) managed to keep the business and build it out, and 4) was a minority. We’d like to have a long list … Continue reading "Refrigerated Trucks"

Morse determined to invent a faster message delivery system. Like Fulton, Morse was an artist before going into business. He had no background in science or engineering. … Continue reading "Telegraph"
Commercial JetlinerJets vastly increases productivity. Early iterations of the industry also enhanced fun and image once the technology improved. The first commercial passenger jet, the Comet, tended to disintegrate mid-flight. Large windows and a poor understanding of metal stress created a literally fatal design flaw. After three crashes the public refused to board the jet. Eventually, … Continue reading "Commercial Jetliner"
Console Gaming SystemsConsole game systems are specialized computers that play games. Ralph Baer came up with the idea of a video-game system that connects to televisions in 1966. Magnavox agreed to manufacture and distribute his seventh prototype, in 1971, branded the Odyssey. Magnavox sold about 350,000 units, at the then steep price of $100, before discontinuing it … Continue reading "Console Gaming Systems"
Processed Foods with Statistical Quality ControlBy design, countless food products look and taste exactly the same. Nobody opens a name-brand candy bar and wonders if it will taste different than any other bar they may have chosen. Each can of Coca Cola, Pepsi, or Guinness Beer tastes exactly the same as any other. All major food companies can thank Guinness … Continue reading "Processed Foods with Statistical Quality Control"

Excluding the vast majority of auto components from innowiki is a purposeful decision. Undoubtedly, these components are oftentimes enormous markets. However, they do not teach us about anything especially important. They are components in a … Continue reading "Windshield Wiper"
Nuclear Aircraft CarrierNuclear aircraft carriers are enormous ships capable of traveling the world indefinitely. Indeed, the ships feature relatively large flight-decks capable of launching and landing fixed-wing aircraft, typically fighters. At 1,123 ft. (342 m.) the USS Enterprise is an enormous ship. In contrast, only oil supertankers are larger. The Enterprise supported 4,600 service members. First launched … Continue reading "Nuclear Aircraft Carrier"
