The Surge Of LED Light Technology

The light bulb is a great hallmark in human technological advancement, even used so far as symbol of invention. But there is a new player in the game of powered illumination and that is the Light-emitting diode.

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p-n junction diode, which emits light when activated. A LED light is also a huge improvement over the traditional light bulb, in many different ways.

More energy efficient, more reliable, more robust, and smaller, LED lights host many formidable advantages. However it’s not all good. LED lights have a high initial price and are more expensive per lumen, on an initial capital cost basis, than most conventional lighting technologies. They are also dependent on a consistent flow of electricity for optimum operation. A fluctuating current can reduce the lifetime of an LED light greatly.


The Driving Force Behind Technological Change

Technology tends to follow necessity. Throughout history humans have continuously come up against challenges. Plagues, wars, natural disasters, climate change. All these influences haven driven technological advancement.

You could also argue that the dreams of man have also been challenges within themselves. To have a burning desire in your heart means to be challenged by following it every day.

It is from these challenges that technology has risen. While World War II induced a horrible loss of human life, there remains the fact that it increased the development of technology across the world.

Most people see problems and disadvantages as just that, negative denominators on successful change. But it couldn’t be further from the truth. The very fact those disadvantages exist is to provide a country or person with the drive, the antagonist to contend with. The very thing that ‘hinders’ the change is the goal to shoot for.

The Advancement Of Technology Throughout History

Technology is a vast and flexible human creation. It began when the first intelligent humans started assembling basic tools and continues to grow into the information age we live in currently.

There has always been one common trend throughout this whole process though. That’s the fact that since the beginning of it all there has always been a reason to advance technology.

Humans have always had to struggle against something. Whether it was the harsh weather, the dark nights, the unfriendly animals. The struggle for survival has always been in the forefront of our minds up until historically very recently.

It’s in this need to handle an issue that humans have come up with the greatest advancements in technology. The emotional drive to live well and be successful gives humans energy to create incredible things.

To this day humans are still conquering new grounds in many areas of life. The insatiable need to solve problems is one of humanity’s greatest strengths and one of our unfortunate weaknesses.




Rise Of The Jet Engine

The jet engine is a reaction engine which discharges a jet. The jet propels the engine as it generates thrust through jet propulsion.

The jet engine is a technology which has evolved throughout history. The first recorded example of a jet engine was developed in ancient Greece in the form of an ‘Aeolipile’ or ‘Heroes Engine’. This is a radial steam turbine, an experiment to ‘judge the mighty and wonderful laws of the heavens and the nature of winds’ as written by the roman author Vitruvius.

The pressure on countries to develop better weapons in WWII propelled the development of the jet engine. As it was apparent that propeller designed engines had limits on a fighter aircraft’s performance.

The first jet fighter to enter WWII was the Luftwaffe Messerschmitt Me 262. When this fighter was combat operational in 1944 it was the fastest fighter in the air, with much better performance than any Allied fighter. But because of trouble with the newly developed jet engines, and the late availability of the aircraft, they had a negligible effect on the final outcome of the war.
