What You'll Learn
The invention of the electric motor
The invention of electricity has been a long and gradual process involving the work of many scientists over several centuries. The first studies into the production of electricity were conducted in the 6th century BC by the Greek philosopher Thales of Miletus, who experimented with amber rods. This method, now known as the triboelectric effect, is extremely inefficient at generating electricity.
The next significant development came in the 18th century with the invention of the voltaic pile, which provided a more reliable source of electrical energy than the electrostatic machines previously used. This was followed by the invention of the electric battery by Alessandro Volta in 1799, which enabled the production of persistent electric currents.
The first commutator DC electric motor capable of turning machinery was invented by English scientist William Sturgeon in 1832. This was followed by the development of a commutator-type direct-current electric motor by American inventors Thomas and Emily Davenport, which they patented in 1837. These motors could run at up to 600 revolutions per minute and were used to power machine tools and a printing press. However, they were commercially unsuccessful due to the high cost of battery power.
Several inventors continued to work on improving the design of DC motors, but they faced the same battery cost issues as the Davenports. It was not until 1834 that German-Russian Moritz von Jacobi created the first truly useful rotating electric motor. The development of electric motors continued to progress, with inventors such as Siemens and Haselwander making important contributions.
The work of Frank Julian Sprague in the late 19th century led to a significant increase in the interest and use of electric motors for industry. Sprague invented the first practical DC motor, which maintained a relatively constant speed under variable loads. He also developed the first electric trolley system, electric elevator, and control system, as well as the electric subway with independently powered centrally-controlled cars.

The evolution of lighting
In 1791, Luigi Galvani discovered bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. This was followed by Alessandro Volta's invention of the voltaic pile in 1800, which provided scientists with a more reliable source of electrical energy. Humphry Davy invented the carbon arc lamp in 1805, which was the first practical electric light. However, it was too powerful for indoor use, and inventors began searching for a way to produce a less powerful electric light for domestic use.
In 1835, James Bowman Lindsay demonstrated an electric lighting system based on light bulbs to the citizens of Dundee. This was followed by the invention of the first incandescent light bulb by Alexander Lodygin in 1874. In 1879, Thomas Edison and Joseph Swan patented the carbon-thread incandescent lamp, marking a significant milestone in the evolution of lighting. This lamp lasted 40 hours, and Edison soon produced a 16-watt lightbulb in 1880 that lasted 1500 hours.
The late 19th century saw intense competition and innovation in the lighting industry, with inventors like Swan in the UK and Edison in the US independently developing functional incandescent lamps. By the early 20th century, incandescent lamps had completely replaced arc lamps. The introduction of the tungsten filament in 1912 by William D. Coolidge further improved the longevity and efficiency of incandescent bulbs.
The first commercial sulfur lamp was sold by Fusion Lighting in 1994, and the first practical blue and white LED was invented in 1995 by Shuji Nakamura, starting an LED boom. Today, electric light is the most common form of artificial lighting, and the invention of electricity has enabled us to illuminate our homes and workplaces with the flick of a switch.

Advancements in power generation
The invention of electricity has transformed our world, and advancements in power generation have been at the forefront of this progress. The story of electricity generation begins with the ancient Greeks, but it is the development of the voltaic pile in the 18th century that provides a viable source of electricity. This early battery, along with electrostatic machines, laid the foundation for future innovations.
The 19th century witnessed rapid progress in electrical science, with notable contributions from pioneers like Luigi Galvani, Alessandro Volta, Hans Christian Ørsted, André-Marie Ampère, and Michael Faraday. Faraday's experiments with electromagnetic induction led to the invention of the first electrical generator in 1831, harnessing mechanical energy to produce electricity.
The middle decades of the 19th century saw substantial developments in generators and motors, with the dynamo being a pivotal invention. This technology made large-scale electricity generation commercially feasible, and by the late 19th century, hydropower was already transitioning into a viable electricity generation source. Thomas Edison's carbon-filament lamp and central generating station in lower Manhattan are also notable milestones.
The 20th century continued to build on these advancements, with the emergence of transistor technology and the first working transistor in 1947. Gas turbine technology also evolved, with the first gas turbine for electric power generation installed in 1939. The Industrial Revolution further emphasised the importance of power generation, particularly with the steam engine's impact on coal demand and mining innovations.
Today, the focus has shifted towards renewable energy sources and sustainable practices. Hydropower, wind, solar, biomass, and tidal power are all part of the evolving landscape of electricity generation. Smart grids, improved solar panel efficiency, and emerging technologies like microbial fuel cells and betavoltaic devices showcase the ongoing advancements in power generation, shaping a more sustainable future.

The development of batteries
In the early 19th century, the Daniell cell was developed, marking a significant improvement over the existing voltaic cell technology. It provided a longer and more reliable current, and its safer and less corrosive nature made it the industry standard, especially for use in the new telegraph networks. The Daniell cell also played a crucial role in defining the volt, the unit of electromotive force.
As the demand for portable electronic devices increased, the need for rechargeable batteries with better energy densities became evident. The nickel-cadmium (NiCd) battery, invented by Waldemar Jungner in 1899, was one of the earliest types of rechargeable batteries used in consumer devices. However, due to the environmental concerns associated with cadmium, nickel-metal hydride batteries (NiMH) were introduced in the latter half of the 20th century. These batteries offered longer life and improved safety but still presented challenges with overheating and overcharging.
In the late 19th century, Gassner's dry cell battery emerged as a more solid and maintenance-free alternative to wet cells. The first mass-produced model, the Columbia dry cell, was marketed by the National Carbon Company in 1896. This innovation made portable electrical devices more practical and directly led to the invention of the flashlight.
The introduction of nickel and lithium-based batteries in the second half of the 20th century revolutionized the development of portable electronic devices, from powerful flashlights to mobile phones. Today, battery technology continues to evolve, with new models being developed to store power generated from renewable sources like solar and wind energy, powering homes more efficiently and sustainably.
