Condensing Steam EngineThe Watt condensing steam engine is widely viewed as the primary machine responsible for the Industrial Revolution. It enabled the use of engines anywhere, not only next to coal mines. Whereas factories before the Watt engines needed to be near high-volume streams, to derive power for water wheels, the Watt engine operated at a low … Continue reading "Condensing Steam Engine"
Bullet TrainsBullet trains are capable of travel at 300kph (186mph). They cost less to operate than aircraft and have a lower environmental impact. Japan invented bullet trains and started acquiring land for their super-fast train in the 1930s, before WWII. In 1959, they broke ground for the first bullet train, or Shinkansen as they’re called in … Continue reading "Bullet Trains"
Slide RuleSlide rules are the original mechanical calculators. They could quickly multiply and divide large numbers. Slide rules are based on logarithms. These are tables of the number another number is raised to produce a third number. Scales of roots do the opposite. John Napier realized sets of log scales placed next to one another easily … Continue reading "Slide Rule"
Marine ChronometerThis device, an accurate clock that works on ships, allows sailors to much more accurately navigate. Before this innovation, sailors had to guess, and it was common for ships to miss their destination on a journey by hundreds of miles. This device reduced the risk and cost of long journeys by ship, lowering the cost … Continue reading "Marine Chronometer"
Niche MarketingWalker, daughter of freed slaves, is the first self-made millionaire woman and the first self-made millionaire African American (maybe – tax returns suggest it was $600K but she did very well for herself). She invented beauty products for Black people. Walker was born in a sharecropper’s cabin. She is orphaned at seven. A freelance launderer, … Continue reading "Niche Marketing"
Milking MachineMilking machine safely and effectively milk cows. They vastly reduce the cost of milking a cow. Background Nobody likes milking cows by hand. It’s time consuming, laborious, and they poop. Early attempts at something better involved inserting catheters that would let the milk slide out. However, if not used perfectly these hurt the animal. Catheters … Continue reading "Milking Machine"
Audion TubeThe Audion acts as an amplifier, transforming quiet electric signals into loud ones. Background In 1906, Lee de Forest invented the “three-electrode Audion” vacuum tube. In 1906, Lee de Forest invented the “three-electrode Audion” vacuum tube. The Audion acts as an amplifier, transforming quiet electric signals into loud ones. Originally de Forest wasn’t quite sure … Continue reading "Audion Tube"
Consumer Shared Computer Network (CompuServe)CompuServe is the first computer network targeted towards ordinary people though it did not start out that way. Background Jeff Wilkins sold burglar alarms. His father-in-law ran a small insurance company and needed to buy a computer. However, the DEC model he wanted had far more computing power than his father required. Wilkins realized he … Continue reading "Consumer Shared Computer Network (CompuServe)"
Hybrid CornGenetic modification by people have produced virtually all plants and animals in the western world. Broccoli, cauliflower, cabbage, kale, kohlrabi, and brussels sprouts are all derived from a wild mustard plant in Europe. None of these vegetables exist but-for early genetic engineering. Similarly, all dogs, cows, pigs, sheep, and chickens are modern man-made creations. Scientists … Continue reading "Hybrid Corn"
Pneumatic Hammer (Jackhammer)1871 As the US and Europe quickly built ever-larger cities and railroads they needed equipment to manipulate the earth at a large scale. The jackhammer is one of these innovations. The jackhammer vastly lowered the cost of blasting rocks and coal. Before the jackhammer men used hammers to blast away at rocks, breaking big rocks … Continue reading "Pneumatic Hammer (Jackhammer)"
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"
Moldboard PlowTraditional plows would become gunked-up with soil, forcing farmers to repeatedly stop and clear away soil. Moldboard plows repel soil, lowering the cost of farming. John Deere was an ordinary blacksmith, creating pitchforks and other common farm instruments. Farmers complained about the time wasted stopping and clearing their plows. Deere thought there must be a … Continue reading "Moldboard Plow"
Blue JeansBlue jeans are fun. The once entirely functional pants evolved to represent a lifestyle. When sold as functional work pants, Levi’s did OK. When sold on emotion sales mushroomed. Background Levi Loeb immigrated from Germany to the US and changed his name to Strauss, which sounded more American. In Germany, Jews were forbidden from owning … Continue reading "Blue Jeans"
Cordless ToolsIn 1895, C&E Fein, a German company, invented the first electric tool. It was a handheld drill weighing 16.5 pounds. The drill was underpowered because it ran on DC electricity. It also required two people to operate. In 1910, Duncan Black sold his car for $600 and used the funds to open a machine shop … Continue reading "Cordless Tools"
PlasticAs described in the post about rubber, Charles Goodyear created the vulcanization plastic making mass-market rubber possible. Goodyear’s durable rubber enabled an entire field of new products from tires to raincoats. However, rubber is both thick and spongy, giving it limited utility. Nobody is going to create a rubber telephone and a rubber water bottle … Continue reading "Plastic"
