This site explores the 9th General Purpose Technology in the current era (AD). The previous eight foundational technologies in order were: the Water Wheel, the Three-masted Ship, Printing, the Factory System, the Steam Engine, Railways, the Iron Steamship, and the Internal Combustion Engine.

A General Purpose Technology is a single, recognizable generic technology that starts out with much room for improvement but becomes widely employed across economies in many use cases, and creates many spillover effects.

Following the noted work of Economists Richard Lipsey and Kenneth Carlaw, General Purpose Technologies (GPTs) have existed since 9000 – 8000 BC with the Domestication of Plants in the Neolithic agricultural revolution.

Discover Electricity

General Purpose Technology-9 is an educational site dedicated to introducing information about how we electrified the world. Here we promote knowledge and stimulate curiosity of the history, technology, and impact of Electricity on society.

From Spark to Society: The Electrifying Rise of Electricity

In the late 19th century, electricity wasn't just about turning on lights. Historians view it as a foundational "general purpose technology" with wide-ranging effects. Centralized power plants replaced inefficient, scattered sources, making electricity more accessible and affordable. This surge of power then electrified factories, dramatically increasing productivity. Communication systems also benefitted, as telegraphs facilitated rapid information exchange and fostered global connections.

So, electricity wasn't just a switch to brighten the room, it was a key driver of industrial growth, a communication revolution, and a defining feature of the modern era.

Beyond Illumination: Electrifying Industries

Imagine a time before light switches and electric toasters. Electricity, in its early days (around the 18th century), was more like a magic trick - sparks flew, things shocked, but there wasn't much practical use. It was a scientific curiosity used for entertainment and simple demonstrations.

But the potential was there - a tiny spark could create a powerful force. The challenge was figuring out how to control it and make it work for us.

The big change came in the mid-19th century with inventors like Michael Faraday, who unraveled the mysteries of electromagnetism, paving the way for generators and power plants. These inventions were like building giant machines that could produce electricity on a much larger scale. Then came the light bulb in 1879, a simple invention by Thomas Edison that transformed everything. Suddenly, homes and businesses could have light at the flick of a switch, no more messy candles or flickering oil lamps! Electricity's potential became clear, and everyone wanted a piece of the action. Another key invention was the transmission line, like a long extension cord that could carry electricity over long distances, developed by innovators like Nikola Tesla in the late 19th century.

Electricity wasn't just about light bulbs. It revolutionized factories and businesses. Powerful electric motors replaced unreliable steam engines, making machines run faster and more efficiently. Homes also got a major upgrade with electric appliances. Imagine keeping food fresh without giant iceboxes? Refrigerators, powered by electricity, brought new convenience to everyday life starting in the early 20th century. Electric fans chased away the summer heat, making homes more comfortable. Communication also took a leap forward with the telegraph and telephone, both powered by electricity. Messages could now travel much faster than ever before.

A Ripple Effect Across Society

The benefits of electricity went far beyond powering lights and appliances. It sparked innovations in other fields as well.

Radios filled the air with music and news, while motion pictures brought stories to life on the big screen. Even medical devices started using electricity for treatments and diagnostics. As electrical equipment became easier to manufacture, the price dropped, making it more affordable for everyone. Skilled electricians, the people who knew how to handle this powerful force, were in high demand across various industries, keeping progress moving forward.

Powering the Future:

Electricity's Everlasting Impact

Now imagine a world plunged into darkness. Traffic lights cease, communication and payments grind to a halt, and basic necessities like refrigeration, cooking meals, pumping gas, and accessing clean water become a struggle. A large-scale power outage, caused by a solar flare or unforeseen event, could send modern societies into disarray, highlighting just how deeply we rely on this invisible force. While renewable power wouldn't eliminate the challenges of a large-scale blackout, an independent energy system could significantly improve a household or business's ability to cope even for limited periods.

Today, electricity is like the invisible power source behind everything we do. Our homes, businesses, and industries all rely on it to function. From powering computers to running MRI machines in hospitals, electricity is the backbone of modern society. And the story's not over yet! Scientists continue to develop new ways to generate, store, and distribute electricity, shaping our world in ways we can only imagine. From a scientific marvel to a fundamental utility, electricity has transformed everything, and its impact continues to electrify our lives.
