Locomotive (High-Pressure Steam Engine)The high-pressure steam engine was invented about the same time by Richard Trevithick in the UK and Oliver Evans in the US. Neither man knew about the other. Richard Trevithick Trevithick, a mining engineer, built a high-pressure steam-powered car, the “Puffing Devil,” in 1801, taking it for a ride around town, picking up friends. He … Continue reading "Locomotive (High-Pressure Steam Engine)"
General Purpose CatalogBackground The general purpose catalog increased the selection and decreased the costs of small-town stores that could only afford to carry limited innovatory. Tiffany’s Blue Book is one of the oldest catalogs, from 1845. There were book, seed, and fabric catalogs in Europe dating back centuries. Ben Franklin created the first US catalog, for scientific … Continue reading "General Purpose Catalog"
LaparoscopyFor centuries surgeons have been purposefully cutting holes in people trying to heal them. Background Before anesthesia, antibiotics, and Lister’s germ theories surgery often meant a slow and painful death from infection. Putting things into perspective, more people died in the US Civil War from infection than from direct strike of a weapon. Purposefully cutting … Continue reading "Laparoscopy"
AutomobileIt’s difficult, and arguably pointless, to separate the innovation of the automobile and Internal Combustion Engine (ICE). The use of an ICE for a “horseless carriage” was so obvious that early engines were all used for cars. Engine propelled buggies were, by far, the most popular use case though ICE’s also powered other applications. Early … Continue reading "Automobile"
Diesel EnginesUses engines use compression to increase engine power. That increases engine power and reduces fuel costs. Diesel is French though studied engineering in Germany. After graduating he returned to Paris and opened an early modern refrigeration factory, patenting several innovations. He eventually left and, barred from the industry, turned his attention to engines. In 1893, … Continue reading "Diesel Engines"
Global Positioning System (GPS)GPS uses satellites to compute positioning in 3D space, allowing automatic mapping and advanced navigation. The Soviet Union launched the Sputnik satellite on October 4, 1957. Sputnik did nothing but send out radio pings audible on radio receivers on earth. Conveniently, they launched the satellite to fly over then arch-enemy the United States. As scientists … Continue reading "Global Positioning System (GPS)"
LASERLASER’s allow light to be intensely focused. There are many uses, from reading digital media at low power to cutting at higher powers. Countless applications rely on LASER technology. In 1957, Arthur Schawlow and Charles Townes, of Bell Labs, worked on an infrared LASER, called an “optical MASER.” They patented the invention in 1958. In … Continue reading "LASER"
- Fourdrinier Paper Making Machine
Fourdrinier machines transform wood pulp into enormous rolls of paper. They vastly reduced the manufacturing cost and, subsequently, the price of paper. Even the smallest Fourdrinier machine is massive and requires an enormous amount of water. Frenchman Louis Roberts invented the papermaking machine. His friend and confidant, Sealy Fourdrinier, patented and commercialized the technology in … Continue reading "Fourdrinier Paper Making Machine"
Reasonably Priced Business Computer (IBM/360)The IBM/360 is the first mass computer, designed as a general-purpose computer affordable for mid-sized businesses yet powerful enough for large enterprises. Background In 1962, IBM’s revenue was $2.5 billion. CEO Thomas Watson Jr. believed in the vision of a general-purpose computer that supports timesharing, the ability of a computer to do multiple things at … Continue reading "Reasonably Priced Business Computer (IBM/360)"
Photography1816 Nicéphore Niépce The Niépce brothers were hell-bent on creating earth-shattering technology and they did so, twice. First, they created the internal combustion engine. Their native France was still adjusting its socioeconomic climate after the revolution so Claude went to England trying to commercialize the engine. During that time, Nicéphore invented photography. This brings us … Continue reading "Photography"
Computer GameBackground Early computers used punch cards to load programs and data into computers. The software was a stack of cards, each card one line of a program. Data input were cards on the top of the stack. Eventually, then the entire thing fed into a card reader. The reader read the stack, processed the data, … Continue reading "Computer Game"
Long Lasting Light BulbEdison’s bulb is well-known but what’s less understood is the enormous infrastructure required to power it. Edison created a power plant in New York City, power cables, transformers, power meters, insulators. When the lights finally came on, at the New York Times building, it represented the end of a herculean undertaking and the beginning of … Continue reading "Long Lasting Light Bulb"
Megawatt WindmillMegawatt wind turbines are windmills capable of generating a megawatt or more of electricity and feeding it into the electrical grid. Background Palmer Putnam was an MIT geologist. Literature notes he has “no formal education or experience in wind power.” Of course, that was true for everybody in the 1930s. There was no such thing … Continue reading "Megawatt Windmill"
Cable TelevisionCable television brings television channels to customers without antennas. Later versions bring more channels than analog antennas provided. Walson owned a small company, Service Electric, located in a mountainous region in Pennsylvania. Frustrated that buyers of his televisions could not receive a signal he climbed a mountain and installed an antenna at the top. Eventually, … Continue reading "Cable Television"
Pneumatic Tires1845 Robert Thomson The wheel is a seminal invention, widely regarded as one of the most important in human history. However, early wooden and stone wheels were far less useful than their modern air-filled rubber counterparts, the pneumatic tire. Despite their ubiquity today, it’s amazing that the pneumatic (air-filled) tire initially went all but unnoticed. … Continue reading "Pneumatic Tires"
