Stainless Steel1913 Harry BrearleyW.H. Hatfield Stainless steel is strong and has high heat resistance, just like ordinary steel. It resists corrosion, it’s formable and weldable and, unlike regular steel, does not rust. It lowered the cost of everyday items.

Furthermore, postal employees sometimes opened and read mail. Government censors … Continue reading "Inexpensive Postage & Stamp"
Mobile PhoneMobile phones allow calls from anywhere that’s within range of a tower. They vastly increase productivity, convenience, lower the risk of a missed call, and they’re fun. Mobile phones work by beaming voice (and, later, data) to a tower, seamlessly switching from tower-to-tower as the person moves. Cooper Creates the Mobile Phone Battery-operated gadget maker … Continue reading "Mobile Phone"
Automatic Automobile TransmissionAutomatic transmissions lower the complexity of driving, removing a barrier of entry. They also allow drivers to focus on the road rather than worries about shifting gears. Automatics vastly simplify driving though, in many countries, drivers who take their test with an automatic transmission may only drive using automatic transmission. Thomas Sturtevant’s automatic transmission system, … Continue reading "Automatic Automobile Transmission"
Videotape RecorderCharles Ginsberg invented the videotape recorder, that put images onto tape, in 1951. Ampex sold their first video recorder, the VRX-1000, in 1956 to CBS for $50,000 ($462,000 in 2018). Ampex recorders were sold exclusively to television studios. Before videotape recordings, television broadcasts either played a movie in front of a TV camera or broadcast … Continue reading "Videotape Recorder"

It was a joint venture between … Continue reading "Chlorofluorocarbons “Freon”"
- Fourdrinier Paper Making Machine
Fourdrinier machines transform wood pulp into enormous rolls of paper. They vastly reduced the manufacturing cost and, subsequently, the price of paper. Even the smallest Fourdrinier machine is massive and requires an enormous amount of water. Frenchman Louis Roberts invented the papermaking machine. His friend and confidant, Sealy Fourdrinier, patented and commercialized the technology in … Continue reading "Fourdrinier Paper Making Machine"

Mini Steel Mill (mini-mill)1969 Ken Iverson “Integrated” steel mills create steel from raw materials. They use the Bessemer process to transform raw materials into enormous amounts of steel. The plants are giant, inflexible, dirty, and expensive to erect and run. Ken Iverson worked at the Nuclear Corporation of America (eventually, Nucor), a conglomerate of assorted businesses pulled together … Continue reading "Mini Steel Mill (mini-mill)"
RailroadRailroads vastly lowered the cost of moving people and goods over land. Richard Trevithick invented the locomotive engine. However, he never quite created a fully functioning railroad: Trevithick’s locomotive was a literal circus act, pulling children around a track at a circus. His core innovation was the idea of a high-pressure steam engine. Prior steam … Continue reading "Railroad"
Wire RopeWire rope is far stronger than natural-fiber rope. German mining engineer Wilhelm Albert invented wire rope about 1834. Wire rope is sometimes called Albert rope after the inventor. Early on, they were used to hoist stuff to and from silver mines in the Hartz Mountain. The first rope was three wrought-iron cables twisted around one … Continue reading "Wire Rope"
Blockchain Explained? Hype or Hope?Blockchain is like the gluten diet a few years back; everybody’s into it but nobody’s quite sure why and few people really need it though to those who do it’s important. I’ll analyze it through the only metric that really matters, value. But before doing that, we need to understand what the it actually is. … Continue reading "Blockchain Explained? Hype or Hope?"
