Aluminum Reduction1886 Charles Martin HallPaul Héroult Aluminum is the most common material in the earth. Despite the abundance of aluminum, it tends to be spread out in tiny flakes impossible to collect by hand. Aluminum reduction vastly lowered the price of extracting aluminum. Before aluminum reduction, aluminum was extremely expensive. People would sift through earth searching … Continue reading "Aluminum Reduction"
Portable VentilatorVentilators breathe for people when they cannot breathe on their own. John Emerson was a physician focused on breathing devices who developed the first mass produced iron lung. Building on Emerson’s work, Bird developed the portable ventilator and, later, created a company, Bird Corp., to commercialize it. Bird Corp. created a home ventilator in 1965, … Continue reading "Portable Ventilator"
Weather ForecastThe development of the telegraph in 1835 made weather forecasting possible. Before that time, people used various methods to guess changes in the weather. Some observations were accurate. For example, the correlation of barometric pressure to weather changes. However, there was not enough geographically widespread data to methodically forecast weather. The Britsh government charged Francis … Continue reading "Weather Forecast"
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)"
Difference EngineBabbage’s Difference Engine, funded by Lovelace, is the first modern mechanical computer. No sooner had he announced his idea than many declared it impractical or even a hoax. Engineers eventually built a working difference engine in 2002 proving Babbage’s ideas were viable, but the engineering processes of his time were inadequate. Presently, there are working … Continue reading "Difference Engine"
Hydraulic Ram (Pump)Allows farmers to raise water from creeks upward, to fields, where it can be used for irrigation without a power source. In the early part of the Industrial Revolution, using a steam engine for farm water would have been prohibitively expensive and pumped far more water than is necessary. The hydraulic ram allows pumping water … Continue reading "Hydraulic Ram (Pump)"
Hydraulic PressBefore the press, shaping metal was a slow, difficult, expensive, and laborious process. The hydraulic press allows metal to be easily and inexpensively shaped. Today, the same hydraulics power a lot of modern industrial equipment. Bramah, a farmer’s son, was an innovator who specialized in locks. He created and patented many types of locks. He … Continue reading "Hydraulic Press"
Sewing MachineBackground In 1829 Thimonnier, a French tailor, innovated the sewing machine. Thimonnier found financiers to build a factory to help commercialize his new machine but workers – fearful the new machine would destroy their livelihood – burnt down the factory. He obtained further patents on better models of sewing machines and won prizes. However, he … Continue reading "Sewing Machine"
SCUBAEarly bell suits that contained air hoses allowed people to function underwater. These bell diving suits were heavy and dangerous. Later systems relied upon compressed air and regulators, yet these were still large and impractical. In 1942 Nazi-occupied France, Frenchmen Cousteau and Gagnan invented the first practical underwater breathing apparatus, Aqua-Lung. In their system, called … Continue reading "SCUBA"
Programmable Logic Controller (PLC)Programmable Logic Controller’s (PLC’s) are small single-purpose computers. They control machines and are common in cars. You probably own more PLC’s than any other type of computer. Today, a single-car has a myriad of PLC’s, usually networked together. PLC’s replace hard-coded wiring, automating tasks. PLC’s often read input from analog sensors. Responding to temperature, sensing … Continue reading "Programmable Logic Controller (PLC)"
- Blue Ocean Strategy Basics – Breaking the Value/Cost Trade-Off
Oftentimes spending more doesn’t get more and, sometimes, gets less Michael Porter is the father of modern business strategy theory and defined a few basic ideas. Core among them is that business centers around competition. Competitors, new market entrants, suppliers, customers, and substitute products are five forces that influence profitability, he argued in his famous … Continue reading "Blue Ocean Strategy Basics – Breaking the Value/Cost Trade-Off"
SubmarineSubmarines changed naval warfare, increasing the risk of maritime travel from hostile countries. Underwater ships have existed in various forms for ages. There was a semi-underwater boat built for Tsar Peter the Great in 1720, and also one allegedly built during the US revolution in 1776. Steamboat baron Robert Fulton built one for the French … Continue reading "Submarine"
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"
Digital Mobile PhoneDigital mobile phones vastly reduce the cost of mobile phones by enabling many more phones to utilize the same number of towers. After the successful launch of analog mobile phones, the need for a digital standard quickly became apparent. Digital phones are smaller, use less power, and require fewer towers. There are two mobile digital … Continue reading "Digital Mobile Phone"
Automobile Assembly LineAssembly lines leverage standardized parts to break auto assembly into discrete components, each that can be done by a small number of people (often just one). Standardized parts evolved into standardized jobs. Ransom Olds, inspired by a musket factory that used standardized parts with workers each focused on one part, created the first auto assembly … Continue reading "Automobile Assembly Line"
