Maritime trip 2012
A motorcycle trip through the Canadian Maritimes, including Nova Scotia, the Cabot Trail, New Brunswick, Prince Edward Island, and Quebec. This trip started as an attempt to ride to the French islands of St. Pierre et Miquelon. While that didn't work out, we still made the best of it and visited the Marconi National Historic Site in Glace Bay, NS. I decided that this might make an interesting destination after reading Thunderstruck by Erik Larson. All in all, another fun ride by the Outlaw Geeks (Tim Flack and myself), and this year's apprentice Geek - Alex Michaud.
CRHnews - Marconi's World First Wireless Telegram Service Clifden
Alcock and Brown (seated in railcar) after their momentous 16 1/2 hour flight across the Atlantic in 1919 in their Vickers Vimy crash landed in Derrygimlagh Bog in Ireland.
This location was some 4 miles south of Clifden in Connemara and adjacent to the pioneering Marconi Wireless Station.
The only means of transport to this out-post was a two-foot gauge railway.
Its principle locomotive was a conversion on an Edwardian Lancia, the adaptation being undertaken by Marconi engineers at their works at Chelmsford and delivered by sea and rail to Clifden.
BBC TV's hugely popular 'Coast' visited Ireland in 2010 and Dick Strawbridge did a first class piece of research and updating of Marconi's Clifden site which in 2017 celebrated its 110th anniversary.
Guglielmo Marconi caused a communications sensation when he transmitted wireless messages from his station at Poldhu in Cornwall to Newfoundland on December 12, 1901, writes Shane Joyce
Having received a grant of $80,000 from the Canadian Government to build a station at Glace Bay in Nova Scotia, he commenced the task of perfecting wireless communication with Poldhu from late 1902.
He experienced extreme difficulty in providing commercially viable communications and decided to move his easterly station as far west as possible and decided on Clifden (Derrigimlagh) after making tests at a number of sites.
The station was not officially opened until 17th October 1907, when commercial signalling commenced between Clifden and Glace Bay.
It was a sight to behold, with the huge condenser house building, the power house with its 6 boilers, and the massive aerial system consisting of 8 wooden masts, each 210 feet high extending eastwards over the hill for a distance of 0.5 kilometres.
The aerials gave off sparks which could be heard in the distance, indicative of the huge power and voltages involved (150KW at 15,000 volts).
As time moved on, advances were made in the technology and a more powerful station was built at Caernarfon in North Wales.
The Clifden station was attacked by republican forces in July 1922 and some buildings were damaged.
The Marconi Company sought compensation from the new Free State government, but this did not materialise.
The station was closed shortly after.
The remains of the station have lain dormant since the contents were sold for scrap after the closure.
Employees of the station have passed away and regrettably, little has been done to record the details of what was a great industrial enterprise of the 20th century.
The Clifden and Connemara Heritage Society are currently planning on developing the site for the public to enjoy. It is expected that this will become a major tourist attraction in a beautiful landscape.
CRHnews says that the former Marconi site has indeed become a major tourist heritage attraction which hopefully should inspire Chelmford City and Essex County Council to promote another world first, Marcon's Hall Street WorX, as a world heritage site.
Marconi Clifden was officially visited by the Italian Ambassador and Princess Elettra Marconi to celebrate its Centenary in 2007.

While waiting in Glace Bay for the video game shop to open i decided to check out the military armory and then stop over and see one of the islands historic sites.

SUMMARY
=======
Cape Breton Island (French: île du Cap-Breton—formerly Île Royale; Scottish Gaelic: Ceap Breatainn or Eilean Cheap Breatainn; Mi'kmaq: Unama'kik; or simply Cape Breton) is an island on the Atlantic coast of North America and part of the province of Nova Scotia, Canada.The 10,311 km2 (3,981 sq mi) island accounts for 18.7% of Nova Scotia's total area. Although the island is physically separated from the Nova Scotia peninsula by the Strait of Canso, the 1,385 m (4,544 ft) long rock-fill Canso Causeway connects it to mainland Nova Scotia. The island is east-northeast of the mainland with its northern and western coasts fronting on the Gulf of Saint Lawrence; its western coast also forms the eastern limits of the Northumberland Strait. The eastern and southern coasts front the Atlantic Ocean; its eastern coast also forms the western limits of the Cabot Strait. Its landmass slopes upward from south to north, culminating in the highlands of its northern cape. One of the world's larger salt water lakes, Bras d'Or (Arm of Gold in French), dominates the island's centre.
The island is divided into four of Nova Scotia's eighteen counties: Cape Breton, Inverness, Richmond, and Victoria. Their total population at the 2016 census numbered 132,010 Cape Bretoners; this is approximately 15% of the provincial population. Cape Breton Island has experienced a decline in population of approximately 2.9% since the 2011 census. Approximately 75% of the island's population is in the Cape Breton Regional Municipality (CBRM) which includes all of Cape Breton County and is often referred to as Industrial Cape Breton, given the history of coal mining and steel manufacturing in this area, which was Nova Scotia's industrial heartland throughout the 20th century.
The island has five reserves of the Mi'kmaq Nation: Eskasoni, Membertou, Wagmatcook, Waycobah, and Potlotek/Chapel Island. Eskasoni is the largest in both population and land area.
Guglielmo Marconi
Guglielmo Marconi, 1st Marquis of Marconi (Italian: [ɡuʎˈʎɛlmo maɾˈkoːni]; 25 April 1874 -- 20 July 1937) was an Italian inventor and electrical engineer, known for his pioneering work on long-distance radio transmission and for his development of Marconi's law and a radio telegraph system. Marconi is often credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun in recognition of their contributions to the development of wireless telegraphy. An entrepreneur, businessman, and founder in Britain in 1897 of The Wireless Telegraph & Signal Company (which became the Marconi Company), Marconi succeeded in making a commercial success of radio by innovating and building on the work of previous experimenters and physicists. In 1924 the King of Italy ennobled Marconi as a Marchese (marquis).

He succeeded in making an engineering and commercial success of radio by innovating and building on the work of previous experimenters and physicists. In 1929, Marconi was ennobled as a Marchese (marquis) by King Victor Emmanuel III of Italy, and, in 1931, he set up the Vatican Radio for Pope Pius XI.
Invention of radio
Many people were involved in the invention of radio in its current form. Experimental work on the connection between electricity and magnetism began around 1820 with the work of Hans Christian Ørsted, and continued with the work of André-Marie Ampère, Joseph Henry, and Michael Faraday. These investigations culminated in a theory of electromagnetism developed by James Clerk Maxwell, which predicted the existence of electromagnetic waves.
After Maxwell's theory was published, many people experimented with wireless communication, some intentionally using Maxwell's theory and some not. It is considered likely that the first intentional transmission of a signal by means of electromagnetic waves was performed by David Edward Hughes around 1880, although this was considered to be induction at the time. The first systematic and unequivocal transmission of EM waves was performed by Heinrich Rudolf Hertz and described in papers published in 1887 and 1890. Hertz famously considered these results as being of little practical value.

SUMMARY
=======
The ionosphere () is the ionized part of Earth's upper atmosphere, from about 60 km (37 mi) to 1,000 km (620 mi) altitude, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth.
