Micro-Electro-Mechanical Systems (MEMS)MEMS are literally microscopic-machines. The best-known MEMS are the accelerometers that have become ubiquitous in smartphones, allowing precise tracking of movement on the X, Y, and Z-axis. Significantly, MEMS are the reason your phone can sense movement. Additionally, other MEMS devices include miniature microphones, projectors, cameras, and countless others. MEMS were first proposed in 1959 … Continue reading "Micro-Electro-Mechanical Systems (MEMS)"
Sit-Flat Paper BagsSure, sit-flat paper bags are not the condensing steam engine, the telegraph, pneumatic tools, or the dynamo generator but they represent something new: a woman entrepreneur. After realizing the hassle of bags that would not stand Margaret Knight set out to create a machine for a bag with a flat bottom. She worked with three … Continue reading "Sit-Flat Paper Bags"
Float GlassBefore float glass (also called flat glass), each piece of glass was individually poured and polished. This was a time consuming and expensive process that left the contours of glass uneven. Pilkington invented a method of floating the glass in a bath or iron tin, leaving both sides of glass perfectly smooth. Float glass took … Continue reading "Float Glass"
TelevisionBefore Farnsworth, there were various types of mechanical TV that used spinning disks (Nipkow disks) and electrical transmitters, none of which ever gained traction. John Logie Baird invented the most widely known mechanical TV. Electrical Television Farnsworth had a small group of innovators, who invested $25,000. They eventually told him to give up so he … Continue reading "Television"
BarbieIn 1945, Harold “Matt” Matson and Elliot Handler created a garage-based manufacturing business. They named it by combining their first names, Mattel. First, they manufactured picture frames. Using the leftover pieces of wood, Elliot built dollhouses that sold well. Soon, Matson dropped out of the business leaving it solely owned by Handler and his wife, … Continue reading "Barbie"
Electronic PaperElectronic paper is an ultra-low-power display that requires electricity only to change. ePaper is useful for eBook readers, grocery store price tags, and other displays that need not rapidly change and cannot be plugged in. Electronic paper is a lesser-known Xerox PARC invention. Helping cement their reputation as the Worst Managers of All Time, Xerox … Continue reading "Electronic Paper"
Privatized SpacePrivate space companies launch rockets that propel satellites (and eventually, people) into space without government funds or bureaucracy. Leaving government out of space removes political influence, simplifies space commercialization, and reduces costs. Elon Musk Elon Musk has a fondness for starting businesses that do the impossible. At first, there was PayPal. At that time, … Continue reading "Privatized Space"
SpreadsheetSpreadsheets simplify calculations and basic database work. Background During a lecture at Harvard Business School, in 1978, student Dan Bricklin watched his professor struggle to erase and rewrite cells in a blackboard-based ledger. Thinking about the newly popular Apple II computer Bricklin thought of a better way, a program that allowed users to enter and … Continue reading "Spreadsheet"
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"
RadarThe origin of Radar is secret. Even after commercialization, the inventors remained in the shadows, secret warriors who enabled the Allies to shoot down the Nazi Lufthansa with eerie precision. Consequently, it was as if the Allies could project through the clouds exactly where the planes were. Of course, that would be impossible… Specifically, Watt … Continue reading "Radar"
Better Oil Drill Bit (Tricone Rotary Rock Drill)A drill bit sounds relatively petty compared to the other inventions on this list. Granted, it’s not Watt’s condensing steam engine, Edison’s long-lasting lightbulb, Tesla’s induction motor or the Wright Brothers airplane. But Hughes drill bit dramatically lowered the cost of drilling for oil. It also opened previously unavailable oil fields where oil reserves lay … Continue reading "Better Oil Drill Bit (Tricone Rotary Rock Drill)"
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"
Adding MachineBlaise Pascal was a French mathematician who lived in the 1600s. He is most known for his work in geometry and statistics but is included here for building the first non-abacus adding machine. Going back briefly, the abacus dates back to at least 300BC. Our earliest cutoff date for innovations is the printing press or … Continue reading "Adding Machine"
Electricity Factory & Distribution NetworkAfter inventing the long-lasting light bulb, Edison needed an electrical grid to deploy his innovation. Remember that, at this time, all electrically powered devices ran off batteries. Background The Edison Electric Illuminating Company, founded after the light bulb company, funded both an electrical generation station, grid, and all supporting equipment. Edison innovated better dynamos, circuits, … Continue reading "Electricity Factory & Distribution Network"
Tri-Motor AirplaneThe Ford Tri-Motor airplane popularized the notion of low-cost, reliable, rugged, and serviceable planes. Before the Ford Tri-Motor, there were countless aircraft, but many were proprietary with difficult-to-service parts that frequently broke down. Along with 20 other wealthy individuals, Ford and his son Edsel funded a new airplane company by designer William Bushnell Stout. In … Continue reading "Tri-Motor Airplane"
