The History of Domestic Lighting
The phenomenon of magnetic and electric effects was studied by ancient Chinese, Greek and Roman scientists.
In 1750, Benjamin Franklin, an American writer, tried to collect electricity in a kite during a thunderstorm. An Italian scientist and Professor of the University of Pavia made a big step forwards with the discovery of the continuous electric power in 1800 which was named after him, called the Volta Pile. The announcement amazed the scientific world and it was from this basic concept that electric light was later developed.
There were several areas of investigation into the electric light, namely, the carbon arc, the incandescent filament bulb, gaseous discharge lights and chemical light.The carbon arc light was the earliest form of electric illumination.
In 1809 the English chemist Sir Humphrey Davy demonstrated his carbon arc lamp at The Royal Institute in London. His invention known as the electric arc light was not put to widespread use until the 1850s.
The sheer brightness of the light and the need for low voltage electricity prohibited its use in confined space unless the illumination was muted by blinds. It was used for street lighting and for lighthouses, but had largely been discontinued by the First World War and replaced by other forms of electricity. However, carbon arc lighting was continued to be used in military applications like search lights on aircraft.
The Incandescent Bulb
The development of the incandescent bulb continued in parallel with that of the are light. In 1865, Hermann Sprengel invented a mercury vacuum pump which allowed a sufficiently high vacuum to be obtained in the bulb for further experiments on the filament to take place. The American, Thomas Edison (1847-1931) - who invented the telegraph — and the Englishman, Joseph Swan (1825-1914) are both credited with having discovered the incandescent filament bulb.
In 1878 Swan heated the filament while evacuating the bulb of its gases, so prolonging its life while Edison achieved 45 hours of illumination from his bulb in 1879. Refinements soon followed: Edison devised the screw-in brass cap and Swan the bayonet fitting. Both were marketing bulbs by the 1880s. A partnership was formed between Swan and Edison, creating the Edison & Swan United Company which later became Ediswan.
In 1881 The Engineer claimed that the first home to be completely illuminated by electricity was the house of Lord Kelvin, a close friend of Swan. His house in Glasgow had been illuminated by 106 gas lights which were converted to electric lights powered by a generator, driven by a gas engine.
In the same year, Sir William Armstrong, engineer and arms manufacturer, lit 45 electric lamps in his famous picturesque Cragside mansion at Newcastle-upon-Tyne, which had been designed by Norman Shaw in the early 1870s. The electricity was generated by a water turbine sited 1500 yards (1.3 km) from his house.

Did you know that ‘Goal Setting’ is the secret to fulfilling ANY dream or desire you want in life? In many sales training courses goal setting is ignored.
Did you also know that SUPER Successful sales people use ‘Goals’ to attain the knowledge and wealth and sales success they have today?
Some of you reading this right now might agree and some of you might not. That decision is yours to make.
The reason people find it too hard to achieve their goals is simple because they’ve set their Long-Term goals before setting Short-Term ones, or they just didn’t plan their goals out carefully.
Goal setting strategies are VERY important, especially for those who want to achieve Long-Term goals.
Well, your in luck because I’m going to share five ‘Goal Setting’ techniques to help you realize your TRUE goals today.
Your only requirement is to keep an open mind.
So, with that said, lets go to Technique #1.
Technique #1. Start with Short-Term goals.
Sometimes, people start with short-term goals unconsciously.
Why unconsciously?
Some of them may have considered the goals to be long-term at the time they planned them; and after achieving a goal, they realize that they are in fact, looking forward to a longer one.
Some are contented with their short-term goals, but after a while will realize that they also need to attain long-term ones.
Short-term goals seem to be our starting point for our Long Term ones.
They also motivate the person to plan for longer goals, which will usually take some time before achieving them in full.
Technique #2. Make sure you really want the goal.
By this, you have to ask yourself: “Do I really want this goal and will this goal give me a better life?”
Answering this ONE question will give you more passion and motivation to achieve your goal.
Some people often recall their past to find out Why and How they came up with such goal.
Technique #3. Speak up.
What I mean by this is you shouldn’t keep your goals to yourself only. By sharing your goals with other people it’ll help you get the support you may need in order to fulfill them.
The problem that usually occurs though is some people are just too shy to tell others about their goals for reasons like they are afraid they cannot achieve them in the end, or they lack the courage to speak their minds.
This is not a good habit to get into because when the time comes that you really need their support, you will have a difficult time getting it.
You’ll then be left to achieve your goals all by yourself.
Don’t make this mistake.
Technique #4. Write down your goals.
This strategy is critical and more advisable for those who have a long list of goals.
After writing them down in as much detail, it is advisable that you review them on a daily to weekly basis because this will encourage and motivate you to achieving them, plus, this will also keep that vision of your goal alive.
Technique #5. Stay on track and never give up.
Reviewing notes will help open your mind to see if you are on the right track. While on track, you may have to face challenges that might change your personality.
A person who is overconfident might suddenly feel depressed after finding out that he is going the wrong way in achieving his goal.
Thus this might lead to abandoning the goal. Never be discouraged. Facing obstacles is a test on how passionate one is to realizing his or her goals.
There you have it. Give those a try and keep a visual picture in your mind everyday of you fulfilling that goal you desire so much.
