Automated Flour Mill : Innowiki

Oliver Evans’ mill vastly lowered the cost while increasing the quality of flour. These mills automated the milling of flour much like Arkwright automated the creation of fabric. The automatic mills were popular with farmers.

Evans automated mill reduced the time and increased the quality and consistency of flour. George Washington purchased one that is still in use, for demonstration purposes, today.

Evans was a prolific innovator and also created a high power steam engine (concurrently with Trevithick) and also designed the core concepts of refrigeration.

Evans had trouble enforcing his patents but, eventually, did make a living from automated mills.

Evans is also, arguably, the innovator of the grain elevator. In an odd twist ー opposite of what usually happens (where people steal and patent the ideas of others) ー Joseph Dart created a grain elevator in 1842 but credits the innovation to Evans.

Washington’s automated Evans Mill is still operational.

Clusters of Regularly Interspaced Short Palindromic Repeats (CRISPR)
CRISPR is like a word processor for DNA. It allows easy and inexpensive gene editing. Edited genes are passed to future generations, making mutations permanent. Doudna and Charpentier Doudna and Charpentier worked on and invented the technology as a team. First, they worked on plants and, later, on animals. History becomes murkier with the involvement … Continue reading "Clusters of Regularly Interspaced Short Palindromic Repeats (CRISPR)"
No-Till Farming
No-till farming is an agricultural process where crops are planted over the prior crop without tilling. Background Since ancient times, farmers believed in the necessity of turning over the soil before planting. Shovels or plows turned over the prior crop, exposing the soil the next crop. Their belief was based on the idea that agricultural … Continue reading "No-Till Farming"
Aluminum Reduction
1886 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"
Long-Term Mortgages
Mortgages are loans to purchase a property. The word derives from the French “mort” and meant death pledge with the obligation ending when the loan was paid off or the property repossessed. Background The Dutch have the earliest mortgages. Originally in the Netherlands, people saved money and purchased their house for cash. However, starting in … Continue reading "Long-Term Mortgages"
Antibiotics
“I did not invent penicillin. Nature did that. I only discovered it by accident.” Sir Dr. Alexander Fleming Few medical discoveries impacted life expectancy and quality of life more than antibiotics. Before their discovery, simple wounds were often fatal. For example, during the US Civil War, most soldiers eventually died from infection, not from their … Continue reading "Antibiotics"
Three Phase Power
One extra wire allows transmission of triple the amount of electricity via three-phase power. With three wires rather than two, electrical operators can transmit triple the electricity. “Polyphase” is another term for three-phase power. Three phase power usually transmits enormous amounts of electricity. These are the large transmission lines on tall polls. Electricity is converted … Continue reading "Three Phase Power"
Catalytic Converter
Catalytic converters prevent knocking in engines without leaded fuel. Houdry was a Frenchman working on high-octane fuels. His initial focus were race cars. Sun Oil sponsored the early work, in the 1930’s, moving Houdry to the US. The fuel work was a success but could not be use in mass production because the catalysts that … Continue reading "Catalytic Converter"
Solar Cells
Solar Cells produce electricity from sunlight. Early History In 1873 and 1874, scientists noticed that selenium reacted with light to produce electricity. During the 1870s William Adams and Richard Day proved that light plus selenium generated current. Eventually, famous German scientist Werner von Siemens (founder of Siemens) was excited about the possibility of solar cells … Continue reading "Solar Cells"
Combine Harvester
Background Before the combine harvester farmers would need to hire groups of people to harvest crops before they rotted. Since there were only so many people available, the ability to harvest limited the volume of crops that could be grown. The harvester fixed that, doing the work of many people at once. This enabled the … Continue reading "Combine Harvester"
Safety Elevator
Before Otis’ elevator buildings were effectively limited in height. Builders could build higher, but nobody was willing to climb too many stairs. Otis’ safety elevator reduced the cost of living and working at high levels in buildings. Background While working to clean an old factory, Otis created a safety catch for hoist, a platform to … Continue reading "Safety Elevator"
Motorcycle
After engineering a buggy that runs on four wheels it didn’t take long to realize a motorized bicycle would work well. Motorcycles are more efficient than cars: they use less fuel and take less space. However, they’re more dangerous than cars, offering far less protection in the event of a crash. They’re also fun. In … Continue reading "Motorcycle"
Insulin
Insulin keeps diabetics alive. Banting and Best discovered insulin, winning them the Nobel Prize. Banting stole most of the credit, but historians argue they co-discovered insulin together. They won the Nobel Prize together. Banting despised Best and the two never spoke again. To continue his work, Banting received a lifetime annuity by the Canadian government. … Continue reading "Insulin"
Instant Photographs
Long before the digital camera Polaroid’s delivered instant photographic gratification, albeit it at a steep price. Like countless tech inventors after him, Land dropped out of Harvard. He sneaked into the labs at Columbia while developing early Polaroid light filter technology. Land’s Polaroid created polarizing light filters, especially useful as sunglasses during WWII. Eventually, he … Continue reading "Instant Photographs"
Float Glass
Before 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"
