The Invention of the Light Bulb: Davy, Swan and Edison\n\nThe first electric light was made in 1800 by Humphry Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc. \nMuch later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England. \n\nIn 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people. \n\nThe inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.

Some historians have reported that Edmond Berger invented an early spark plug on February 2, 1839. However, Edmond Berger did not patent his invention. Spark plugs are used in internal combustion engines and in 1839 these engines were in the early days of experimentation. Therefore, Edmund Berger's spark plug if it did exist would have had to have been very experimental in nature as well or perhaps the date was a mistake. \n\nAccording to Britannica a spark plug or sparking plug is, "a device that fits into the cylinder head of an internal-combustion engine and carries two electrodes separated by an air gap, across which current from a high-tension ignition system discharges, to form a spark for igniting the fuel." \n \nOliver Lodge invented the electric spark ignition (the Lodge Igniter) for the internal combustion engine. Two of his sons developed his ideas and founded the Lodge Plug Company. Oliver Lodge is better known for his pioneering work in radio and was the first man to transmit a message by wireless.  \n\nAlbert Champion \nDuring the early 1900s, France was the dominant manufacturer of spark plugs. Frenchman, Albert Champion was a bicycle and motorcycle racer who immigrated to the United States in 1889 to race. As a sideline, Champion manufactured and sold spark plugs to support himself. In 1904, Champion moved to Flint, Michigan where he started the Champion Ignition Company for the manufacturing of spark plugs. He later lost control of his company and in 1908 started the AC Spark Plug Company

In 1882, Latimer developed and patented a method of manufacturing his carbon filaments.\n\nIn 1903, Willis R. Whitney invented a treatment for the filament so that it wouldn't darken the inside of the bulb as it glowed. In 1910, William David Coolidge (1873-1975) invented a tungsten filament which lasted even longer than the older filaments. The incandescent bulb revolutionized the world.

"In 1926, Einstein and former student Leó Szilárd co-invented the Einstein refrigerator. On November 11, 1930, U.S. Patent 1,781,541 was awarded to Albert Einstein and Leó Szilárd for the refrigerator. The patent covered a thermodynamic refrigeration cycle providing cooling with no moving parts, at a constant pressure, with only heat as an input. The refrigeration cycle used ammonia, butane, and water."\n\nFrom Wikipedia, http://en.wikipedia.org/wiki/Einstein\n\nHope this helps!

The Ronson Company (https://www.ronson.nl/pages_en/ronsonhistory.php) claims to be the inventor of the mechanical lighter a 100+ years ago.\n\nIn 1896, Louise V. Aronson starts to work on a new type of match. By then the ignition of the matches’ ware made out of the highly poisoning Phosphor. Aronson makes the match with a sulphur ignition and registered his invention under the name “Safety Match” on 16 March 1897. That same year, the company moves premises from New York to Newark, New Jersey. By then Art Metal Company is not a one-man operation anymore and the name changes to ‘Art Metal Works’. Louis V. Aronson is President of the company and Max Hecht vice-president. \n\nArt Metal Works manufactured various art and home decoration products as, clocks, vases, desk sets, miniatures and many other novelties useful for wedding- and holiday gifts. Louis V. Aronson still interested with the new ways of ignitions. He meets Alexander Harris who is born in New York and educated in London. Alexander Harris is also inventor and shares Aronson’s passion for new ways of ignition. In 1908 Alexander Harris joins the company and together they start to work on the development of lighters. \n\nIn 1910 Louis V. Aronson granted his first lighter patent. This spark producing apparatus, is an ignition system without any fuel specification, the name on the patent is Pist-o-Liter. This sparking apparatus is based on the metal alloy “Ferro-Cerium” invented by the Austrian “Dr. Carl Auer von Weisbach” two years before. The name Ferro-Cerium was named Auermetal referring to the inventor Dr. Carl Auer von Weisbach. Now or days the Auermetal is better known as “Flints” that still is used in the lighters. For Aronson and Harris this was the start of their both passion to invent / create a proper ‘flame lighter’.

Joseph Francis\n\n\n\nFRANCIS, Joseph, inventor, born in Boston, Massachusetts, 12 March 1801. At eleven years of age he exhibited a fancy boat at a fair, and at the age of eighteen received from the Massachusetts mechanics' institute the first prize for a fast rowboat. He afterward established a boatyard in New York, and was requested by the secretary of the navy to go to Portsmouth navy yard and build wooden lifeboats for the frigate "Santee " and the line-of-battle ship "Alabama." Soon after this he invented a portable boat that could be taken apart, and a method of building boats over a frame or mould with inch square strips of cedar nailed edge to edge, the joining showing neither nail heads or seams, and requiring no calking. These boats, all of which were lifeboats, came into general use. His greatest achievements were in the construction of lifesaving appliances. These consisted of lifeboats, life cars, and surf lifeboats. Of the lifeboats the first that he made was of wood, and was called the "Hydrogen " lifeboat. The interior was fitted with copper air tubes, and the invention proved successful. As a result of later experiments, the use of wood in the construction of his boats quickly gave way to iron, although the use of iron in the manufacture of vessels of any kind was practically unknown at that time. To Mr. Francis may be conceded the first use of iron floating vessels. \n\nAnother improvement was added by having the spaces at the bow and stern of the boats made into reservoirs of air, as well as the spaces at the sides, enabling the boat to sustain a great load in the heaviest sea. In 1838 Mr. Francis invented the life car by which to land people safely from a wreck. He began with experiments on wooden lifeboats, and finally, in 1842, invented the corrugated metallic life car, with space for four adults. His first perfect metallic life car was placed on the coast of New Jersey, near Long Branch, in the autumn of 1849, at his own expense, the government refusing to aid him in any way. The boat was not called into use until January 1850, when the British emigrant vessel "Ayrshire" was wrecked on Squan Beach in a violent winter storm. There were 201 persons on board, and 200 were saved by means of the life car. The one loss of life that occurred was that of a man who insisted on attempting to ride through the surf on the outside of the ear, when his family was inside. This car was for a long time preserved in the museum in Central park, New York, but on 10 July 1885, it was deposited, as a relic, in the National museum in Washington. \n\nDuring the first four years of the use of lifeboats (1850'3) they were instrumental in saving 2,150 lives, besides an immense amount of valuable cargo. Mr. Francis's metallic life surfboat, invented in 1845, was designed for riding lightly on the wildest sea. In 1845 Mr. Francis obtained patents in the United States, England, France, Germany, and Russia, for his method of constructing vessels of corrugated sheet metal, and for the machinery by which they were produced. His inventions for the machinery and for the application of the hydraulic press were adjuncts of the greatest importance. He furnished lifeboats built on the principle of the corrugated sheet metal for the Dead Sea and Arctic expeditions, to the war, navy, and treasury departments, and to several European governments. Mr. Francis has extended the application of corrugated metal to the building of steamers, floating docks, harbor buoys, and pontoon wagons, and every civilized country has adopted his inventions. \n\nAmong his many other inventions are a military hood made of cloth for the protection of sentinels in a storm, a circular yacht, and a double joint rowlock. He has received numerous medals and decorations from European sovereigns. The order of knighthood of St. Stanislaus, with its medal and diploma, was conferred upon him in 1861, and on 4 February 1856,

Thomas Edison - would test over and over and over...and find 100 things that did not work.....think of the light bulb..and I think you will see the light!.....along with  about a thousand other things called inventions!

false, but the rumor probably started I believe one of Edison's bulbs is still burning in Menlo park (his lab).\n\nIt's never been turned off, which helps it last longer.

The vacuum flask was invented by the Scot Sir James Dewar, while working as a scientist at Oxford University in 1892.\n\nThe first barometer was devised by Evangelista Torricelli, a student of Galileo Galilei, in 1643.\n\nThe best known safety lamps are the Davy lamp, invented by Sir Humphry Davy and the Geordie lamp, invented by George Stephenson. Both of those were invented in 1815 and have been superseded by the Gray, Muesler, Marsant, and other lamps; most later lamps are constructed on the principle discovered by Davy, that a flame enveloped in wire gauze of a certain fineness does not ignite firedamp.

Sir Isaac Newton, held the theory that light was made up of tiny particles. In 1678, Dutch physicist, Christiaan Huygens, believed that light was made up of waves vibrating up and down perpendicular to the direction of  the light travels, and therefore formulated a way of visualising wave propagation. This became known as 'Huygens' Principle'.  Huygens theory was the successful theory of light  wave motion in three dimensions. Huygen, suggested that light wave peaks form surfaces like the layers of an onion. In a vacuum, or other uniform mediums, the light waves are spherical, and these wave surfaces advance or spread out as they travel at the speed of light. This theory explains why light shining through a pin hole or slit will spread out rather than going in a straight line (see diffraction). Newton's theory came first, but the theory of Huygens, better described early experiments. Huygens' principle lets you predict where a given wavefront will be in the future, if you have the knowledge of where the given wavefront is in the present.

Boy, you are really time-constrained!  What kind of light?  Edison did an experiment on sending sound over light waves, but was limited to visual light, in air (not laser light, in fiber optics like we use today.)  What equipment have you?\nSuggestions, without knowing much:  Send a beam of light as Morse Code and determine the maximum distances based on different times of day, weather conditions, strength of light beam, type of light beam, acuteness of receiver's eyes.  \n\nOr better yet if you are a computer geek  :), do it with a photo cell as the receiver and send the signal to a computer for analysis and conversion into text.\n\nGood Luck!  Let me know your results!
