Chuck Hull invents stereolithography
Stereolithography is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photopolymerization.
Technology & innovation
China builds its first major solar farm
China’s first 10kW civil photovoltaic power station, which is also the oldest existing photovoltaic power station in China, was built in Xiaocha Village, Yuanzi Township, Yuzhong County, Gansu Province, providing domestic electricity for 130 local households. After 40 years, the plant is still generating electricity at around 7 kW.
IBM releases Microsoft’s MS-DOS
MS-DOS was the main operating system for IBM PC compatible personal computers during the 1980s and the early 1990s.
U.S. Windpower installs the world’s first wind farm in New Hampshire
The world’s first wind farm stood on the north side of Crotched Mountain in southern New Hampshire, on land owned by the Crotched Mountain Rehabilitation Center, a hospital and school that serves individuals with disabilities and their families. It consisted of 20 30kW turbines – quite small by standards of the 2020s.
Robert Austrian, Jerome Gold, and colleagues develop world’s first pneumococcal vaccine
With the discovery of penicillin in 1928, interest in vaccines to prevent pneumonia waned. The assumption was that the problem would largely be eliminated by use of this antibiotic. Austrian and Gold, however, showed that, despite treatment with penicillin, deaths from pneumococcal pneumonia were unchanged in the first 96 hours of therapy. These efforts ultimately led to the licensing first of a 14-valent pneumococcal polysaccharide in 1977 followed by the 23-valent pneumococcal polysaccharide in 1983.
China begins producing solar energy cells for first time
The first solar cell factories were located in Ningbo and Kaifeng. Annual national solar capacity installations were still low, as only 0.5 kW of photovoltaic capacity was installed. This increased to 8 kW in 1980, 70 kW in 1985, 500 kW in 1990, and 1550 kW in 1995. Soon, China would become the world’s undisputed leader in solar energy production.
The Altair 8800 sparks the microcomputer revolution
The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU. Interest grew quickly after it was featured on the cover of the January 1975 issue of Popular Electronics.
Construction begins on the Very Large Array in New Mexico
The Very Large Array is the most versatile, widely-used radio telescope in the world.
Motorola employee Martin Cooper makes the world’s first cell phone call
Using a prototype of what would become the Motorola DynaTAC 8000x, the world’s first commercial cell phone, Cooper placed a call to the headquarters of Bell Labs in New Jersey.
Bill Bowerman invents the Waffle Trainer
The origins of the Oregon Waffle, afterwards named the Waffle Trainer, derive from Bowerman’s experiments with a simple waffle iron, the grooves of which proved to be a near perfect mold for a running shoe.
