Prefabricated Housing ComponentsHistory Limited amounts of prefabricated components date back to ancient times. Mesopotamian’s used burnt clay bricks. Romans utilized concrete molds for aqueducts and tunnels and William the Conqueror conquered the concept. There were movable modular buildings for industry, defense, and even hospitals. However, hand construction was the norm for the vast majority of houses and … Continue reading "Prefabricated Housing Components"
Fighter AircraftBackground In 1903, Wilbur and Orville Wright invented the airplane. Other aircraft preceded theirs, lifted aloft by lighter-than-air elements, but the wright brothers smaller and faster airplane was a new breakthrough. People could fly like birds, except faster and higher. The Wright Brothers were furiously worried about their intellectual property being stolen. In hindsight, their … Continue reading "Fighter Aircraft"
Movie SoundTalkie movies increased fun but also increased the utility of movies by enabling the transmission of news with pictures. Newsreels, that started out as shorts played before movies, evolved into the most effective communication method in history. Tigerstedt created the first documented movie sound technology, in 1914. However, his technology was not commercialized. Lee de … Continue reading "Movie Sound"
- Blue Ocean Strategy Basics – Making Competition Irrelevant
A different way of thinking. It’s right there on the front of the jacket of the book Blue Ocean Strategy, “How to Create Uncontested Market Space and Make the Competition Irrelevant.” It’s also one of the most misunderstood concepts of blue ocean strategy. I’ve been working on blue ocean strategy since 2001, when it was … Continue reading "Blue Ocean Strategy Basics – Making Competition Irrelevant"
Supersonic FlightOn Tuesday, October 14, 1947, a B-29 bomber took off in the Mojave Desert in California. Instead of a bomb, it carried another plane. Chuck Yeager & the X-1 The Bell X-1 “research vehicle” was a rocket fired aircraft. As the bomber climbed, test pilot Capt. Charles E. “Chuck” Yeager, climbed into the rocket aircraft. … Continue reading "Supersonic Flight"
Electric Arc WeldingElectric arc welding lowered the price of joining metal pieces, eventually enabling the construction of much larger structures. Russians love to build giant things, bolshoya as they say in Russian. Therefore, it makes sense that it was a Russian, Benardos Nikolai Nikolaevic, who realized in 1881 that two metal pieces can be tightly joined together … Continue reading "Electric Arc Welding"
Musical Instrument Digital Interface (MIDI)MIDI allows instruments to talk to computers and to one another. As engineers began connecting instruments to computers it became clear there needed to be a standard interface so that each instrument did not need to “talk” differently to each computer. Smith, who holds degrees in computer science and electrical engineering. He created the MIDI … Continue reading "Musical Instrument Digital Interface (MIDI)"
Cotton GinWhitney’s innovation vastly lowered the price of cotton. Before Whitney’s cotton gin, producing cotton was economically inefficient because of the enormous cost to separate cotton from seeds. After the innovation, cotton became a profitable crop. Background Coming of age during the Revolutionary War, Whitney made a nail company, at the age of 15. Later, he … Continue reading "Cotton Gin"
ParachuteParachutes lowered the risk of flight, encouraging innovation in flying. In 1782, the Montgolfier brothers launched the first hot air balloon from the grounds of the Palace of Versailles. King Louis XVI and Marie Antoinette — the last of the French aristocracy who would be beheaded during the revolution — watched as the balloon lifted … Continue reading "Parachute"
Tractor Treads1904 Benjamin Holt “In the Roberts Island tract, where a man could not walk without sinking to his knees, and where tule-shoed horses could not be used, the new traction engine was operated without a perceptible impression in the ground.” Farm Implement News, May 18, 1905 “It looks like a caterpillar,” said a photographer observing … Continue reading "Tractor Treads"
Polio VaccineAppearing out of nowhere in the late 1900s, polio terrified American communities in the early 20th century. 1 in 200 infections led to irreversible paralysis. Of those, 5-10% died from breathing paralysis. Iron lungs that breathed for polio sufferers also trapped them. The virus paralyzed President Roosevelt. No sooner did the virus appear than entire … Continue reading "Polio Vaccine"
FiberglassFiberglass has multiple uses. It acts as an insulator, building material, and even boat hulls. First, in 1870, John Player developed a process to mass-produce glass strands with seam jets used for insulation. By and large, this is arguably the first fiberglass. Eventually, in 1880, Herman Hammesfahr patented weaving glass fibers to silk, making it … Continue reading "Fiberglass"
Discount AirlineAs the airline market developed, the US found it necessary to regulate interstate air transport as a “public utility.” Significantly, the “Civil Aeronautics Board” (CAB) regulated fares, routes, and schedules. The benefit of regulation was predictability and widespread routes. For example, a carrier that wanted to fly from New York to Chicago might be required … Continue reading "Discount Airline"
Coke Fueled Blast Furnace / Pig Iron1709 Abraham Darby used Coke instead of coal to fire blast furnaces, making the production of iron from pig iron (a weak iron), much more economical. Coke burns significantly hotter than coal which, combined with his new design to concentrate the heat, his factory was significantly more efficient than prior methods. He created the Bristol … Continue reading "Coke Fueled Blast Furnace / Pig Iron"
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"
