93-644: The PS ( paddle steamer ) Comet was built in 1812 for Henry Bell , a Scottish engineer who with his wife had become proprietor of the Baths Hotel offering sea bathing in Helensburgh . On 15 August 1812, Bell's ship began a passenger service on the River Clyde , connecting Helensburgh to Greenock and Glasgow . This was the first commercially successful steamboat service in Europe. Bell obtained

186-462: A barge -hauler, Charlotte Dundas , for the Forth and Clyde Canal Company . It successfully hauled two 70-ton barges almost 20 mi (32 km) in 6 hours against a strong headwind on test in 1802. Enthusiasm was high, but some directors of the company were concerned about the banks of the canal being damaged by the wash from a powered vessel, and no more were ordered. While Charlotte Dundas

279-620: A boat with a pair of paddlewheels at each end turned by men operating compound cranks. The concept was improved by the Italian Roberto Valturio in 1463, who devised a boat with five sets, where the parallel cranks are all joined to a single power source by one connecting rod, an idea adopted by his compatriot Francesco di Giorgio . In 1539, Spanish engineer Blasco de Garay received the support of Charles V to build ships equipped with manually-powered side paddle wheels. From 1539 to 1543, Garay built and launched five ships,

372-644: A double-hulled boat that was propelled on the Firth of Forth by men working a capstan that drove paddles on each side. One of the first functioning steamships , Palmipède , which was also the first paddle steamer, was built in France in 1774 by Marquis Claude de Jouffroy and his colleagues. The 13 m (42 ft 8 in) steamer with rotating paddles sailed on the Doubs River in June and July 1776. In 1783,

465-457: A full rig of sail for when winds were favorable, being unable to complete the voyage under power alone. In 1822, Charles Napier 's Aaron Manby , the world's first iron ship, made the first direct steam crossing from London to Paris and the first seagoing voyage by an iron ship. In 1838, Sirius , a fairly small steam packet built for the Cork to London route, became the first vessel to cross

558-516: A jetty. The paddle steamers between them were estimated to have rescued 26,000 Allied troops during the operation, for the loss of six of them. The Science Museum The Science Museum is a major museum on Exhibition Road in South Kensington , London. It was founded in 1857 and is one of the city's major tourist attractions, attracting 3.3 million visitors annually in 2019. Like other publicly funded national museums in

744-448: A means of propulsion comes from the fourth– or fifth-century military treatise De Rebus Bellicis (chapter XVII), where the anonymous Roman author describes an ox-driven paddle-wheel warship: Animal power, directed by the resources on ingenuity, drives with ease and swiftness, wherever utility summons it, a warship suitable for naval combats, which, because of its enormous size, human frailty as it were prevented from being operated by

837-559: A new paddle steamer by de Jouffroy, Pyroscaphe , successfully steamed up the river Saône for 15 minutes before the engine failed. Bureaucracy and the French Revolution thwarted further progress by de Jouffroy. The next successful attempt at a paddle-driven steam ship was by Scottish engineer William Symington , who suggested steam power to Patrick Miller of Dalswinton . Experimental boats built in 1788 and 1789 worked successfully on Lochmaben Loch. In 1802, Symington built

930-694: A paddle-wheel ship from China is in the History of the Southern Dynasties , compiled in the 7th century but describing the naval ships of the Liu Song dynasty (420–479) used by admiral Wang Zhen'e in his campaign against the Qiang in 418 AD. The ancient Chinese mathematician and astronomer Zu Chongzhi (429–500) had a paddle-wheel ship built on the Xinting River (south of Nanjing ) known as

1023-466: A rod and lever. The geometry is designed such that the paddles are kept almost vertical for the short duration that they are in the water. The use of a paddle wheel in navigation appears for the first time in the mechanical treatise of the Roman engineer Vitruvius ( De architectura , X 9.5–7), where he describes multigeared paddle wheels working as a ship odometer . The first mention of paddle wheels as

1116-418: A scientific twist". Up to 380 children aged between 7 and 11, accompanied by adults, are invited to spend an evening performing fun "science based" activities and then spend the night sleeping in the museum galleries amongst the exhibits. In the morning, they're woken to breakfast and more science, watching a show before the end of the event. On the evening of the last Wednesday of every month (except December)

1209-582: A screen measuring 24.3 by 16.8 metres, with both a dual IMAX with Laser projection system and a traditional IMAX 15/70mm film projector, and an IMAX 12-channel sound system. Visitors to the Who Am I? gallery can explore the science of who they are through intriguing objects, provocative artworks and hands-on exhibits. Energy Revolution: The Adani Green Energy Gallery explores how the world can generate and use energy more sustainably to urgently reduce carbon dioxide emissions from global energy systems and limit

1302-522: A service on the Firth of Forth . Bell had the Comet lengthened and re-engined, and from September 1819 ran a service to Oban and Fort William (via the Crinan Canal ), a trip which took four days. On 15 December 1820 the Comet was wrecked in strong currents at Craignish Point near Oban, with Bell on board. There were no deaths. One of the engines ended its working days in a Greenock brewery, and

1395-502: A side,". The standard Chinese term "wheel ship" was used by the Song period, whereas a litany of colorful terms were used to describe it beforehand. In the 12th century, the Song government used paddle-wheel ships en masse to defeat opposing armies of pirates armed with their own paddle-wheel ships. At the Battle of Caishi in 1161, paddle-wheelers were also used with great success against

1488-419: A simple paddle wheel, where the paddles are fixed around the periphery, power is lost due to churning of the water as the paddles enter and leave the water surface. Ideally, the paddles should remain vertical while under water. This ideal can be approximated by use of levers and linkages connected to a fixed eccentric. The eccentric is fixed slightly forward of the main wheel centre. It is coupled to each paddle by

1581-483: A single paddlewheel at the stern ; and (rarely) inboard, with the paddlewheel mounted in a recess amidships. The earliest steam vessel s were sidewheelers, and the type was by far the dominant mode of marine steam propulsion, both for steamships and steamboats, until the increasing adoption of screw propulsion from the 1850s. Though the side wheels and enclosing sponsons make them wider than sternwheelers, they may be more maneuverable, since they can sometimes move

1674-541: A steam-powered desalinator created by Garay for a steam boiler. In 1705, Papin constructed a ship powered by hand-cranked paddles. An apocryphal story originating in 1851 by Louis Figuire held that this ship was steam-powered rather than hand-powered and that it was therefore the first steam-powered vehicle of any kind. The myth was refuted as early as 1880 by Ernst Gerland  [ de ] , though still it finds credulous expression in some contemporary scholarly work. In 1787, Patrick Miller of Dalswinton invented

1767-612: A table. Comet was reported as "brightly painted, having for her figurehead a lady garbed in all the colours of the rainbow". Comet was launched on 24 July 1812 with her trial run on 6 August from Port Glasgow to the Broomielaw in Glasgow, taking three and a half hours for the 20 miles (32 kilometres). The double paddlewheels were found to be unsatisfactory and a pair of single wheels were substituted which increased her speed to almost 7 knots . On 15 August 1812, Bell advertised in

1860-685: A variety of themes concerning the museum's development. The Science Museum consists of two buildings – the main building and the Wellcome Wing. Visitors enter the main building from Exhibition Road, while the Wellcome Wing is accessed by walking through the Energy Hall, Exploring Space and then the Making the Modern World galleries (see below) at ground floor level. The Energy Hall is the first area that most visitors see as they enter

1953-466: Is not 'greenwash'". There have been protests against the sponsorship; in May 2021, a group calling themselves 'Scientists for XR' ( Extinction Rebellion ) locked themselves to a mechanical tree inside the museum. The UK Student Climate Network carried out an overnight occupation in June 2021, and were threatened with arrest. In August 2021, members of Extinction Rebellion held a protest inside and outside

2046-745: Is now in The Science Museum in London. In 1875, the schooner Ann was driven against a steamship at Greenock , Renfrewshire and sank. The Glasgow Herald reported a piece from the Greenock Telegraph which stated "part of the hull of the Ann was all that was left of Henry Bell's old Comet, the first steam-vessel ever to sail in European waters. Some years ago she was bought up by Smillie, of Glasgow, and Bell's old engine taken out. She

2139-687: Is one of the funding partners of the museum's STEM Training Academy. Equinor's sponsorship of the Wonderlab exhibit was on the basis that the Science Museum would not make any statement to damage the oil firm's reputation. Shell has influenced how the museum presents climate change in its programme sponsored by the oil company. The museum has signed a gagging clause in its agreement with Shell not to "make any statement or issue any publicity or otherwise be involved in any conduct or matter that may reasonably be foreseen as discrediting or damaging

2232-592: The Comet filled, and in two minutes went down head foremost. The moment this look place, the Ayr , instead of lending any assistance, gave her paddles a back stroke, turned round, and went off to Greenock, leaving them to their fate. Comet II sank very quickly, killing 62 of the estimated 80 passengers on board, including the son-in-law of John Anderson , a friend of Robert Burns . Also drowned were recently married Captain Wemyss Erskine Sutherland of

2325-658: The Crimean War of 1853–1856, and by the United States Navy during the Mexican War of 1846–1848 and the American Civil War of 1861–1865. With the arrival of ironclad battleships from the late 1850s, the last remaining paddle frigates were decommissioned and sold into merchant-navy service by the 1870s. These included Miami , which became one of the first Boston steamers in 1867. At

2418-486: The Dunkirk Evacuation in 1940, where they were able to get close inshore to embark directly from the beach. One example was PS  Medway Queen , which saved an estimated 7,000 men over the nine days of the evacuation, and claimed to have shot down three German aircraft. Another paddle minesweeper, HMS  Oriole , was deliberately beached twice to allow soldiers to cross to other vessels using her as

2511-860: The Jin dynasty (1115–1234) navy. The Chinese used the paddle-wheel ship even during the First Opium War (1839–1842) and for transport around the Pearl River during the early 20th century. Paddle steamers in Bangladesh were first operated by the River Steam Navigation Company Limited in 1878. Many steamers, including the Garrow , Florikan , Burma , Majabi , Flamingo , Kiyi , Mohamend , Sherpa , Pathan , Sandra , Irani , Seal , Lali , and Mekla , dominated

2604-629: The National Collections Centre , at the Science Museum Wroughton, in Wiltshire. The Science Museum has a dedicated library, and until the 1960s was Britain's National Library for Science, Medicine and Technology. It holds runs of periodicals, early books and manuscripts, and is used by scholars worldwide. It was, for a number of years, run in conjunction with the library of Imperial College , but in 2007

2697-707: The Racecourse-class minesweepers , were ordered and 32 of them were built before the end of the war. In the Second World War , some thirty pleasure paddle steamers were again requisitioned; an added advantage was that their wooden hulls did not activate the new magnetic mines. The paddle ships formed six minesweeping flotillas , based at ports around the British coast. Other paddle steamers were converted to anti-aircraft ships. More than twenty paddle steamers were used as emergency troop transports during

2790-621: The River Clyde in 1812. In 1812, the first U.S. Mississippi River paddle steamer began operating out of New Orleans. By 1814, Captain Henry Shreve had developed a "steamboat" suitable for local conditions. Landings in New Orleans went from 21 in 1814 to 191 in 1819, and over 1,200 in 1833. The first stern-wheeler was designed by Gerhard Moritz Roentgen from Rotterdam, and used between Antwerp and Ghent in 1827. Team boats , paddle boats driven by horses, were used for ferries

2883-819: The South Kensington Museum , together with what is now the Victoria and Albert Museum . It included a collection of machinery which became the Museum of Patents in 1858, and the Patent Office Museum in 1863. This collection contained many of the most famous exhibits of what is now the Science Museum. In 1883, the contents of the Patent Office Museum were transferred to the South Kensington Museum. In 1885,

2976-581: The Thames steamers which took passengers from London to Southend-on-Sea and Margate , Clyde steamers that connected Glasgow with the resort of Rothsay and the Köln-Düsseldorfer cruise steamers on the River Rhine . Paddle steamer services continued into the mid-20th century, when ownership of motor cars finally made them obsolete except for a few heritage examples. The first mention of

3069-486: The screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of

3162-506: The " thousand league boat ". When campaigning against Hou Jing in 552, the Liang dynasty (502–557) admiral Xu Shipu employed paddle-wheel boats called "water-wheel boats". At the siege of Liyang in 573, the admiral Huang Faqiu employed foot-treadle powered paddle-wheel boats. A successful paddle-wheel warship design was made in China by Prince Li Gao in 784 AD, during an imperial examination of

3255-423: The 1820s, paddle steamers were used to take tourists from the rapidly expanding industrial cities on river cruises, or to the newly established seaside resorts , where pleasure piers were built to allow passengers to disembark regardless of the state of the tide. Later, these paddle steamers were fitted with luxurious saloons in an effort to compete with the facilities available on the railways. Notable examples are

3348-619: The 1980s, the steam engines were replaced with diesel ones, and the wooden paddles were replaced with iron ones. Hydraulic steering was introduced in the 1990s, followed by electro-hydraulic systems in 2020. Modern equipment such as radar and GPS was also installed. However, PS Gazi , PS Teal , and PS Kiwi were decommissioned in the late '90s after catching fire while docked for repairs. Until 2022, four paddle steamers—PS Ostrich (built in Scotland in 1929), PS Mahsud (1928), PS Lepcha (1938), and PS Tern (1950)—were operated by

3441-509: The 33rd Regiment and Sarah née Duff of Muirtown. After the loss of his second ship, Bell abandoned his work on steam navigation. A replica of the Comet , situated in Port Glasgow, was built by Lithgows shipyard apprentices in 1962 for the 150th anniversary of the original. As part of the anniversary celebrations the replica sailed from Port Glasgow to Helensburgh and back, accompanied by a flotilla of small ships. In 2011, just before

3534-467: The Atlantic under sustained steam power, beating Isambard Kingdom Brunel 's much larger Great Western by a day. Great Western , however, was actually built for the transatlantic trade, and so had sufficient coal for the passage; Sirius had to burn furniture and other items after running out of coal. Great Western ' s more successful crossing began the regular sailing of powered vessels across

3627-644: The Atlantic. Beaver was the first coastal steamship to operate in the Pacific Northwest of North America. Paddle steamers helped open Japan to the Western World in the mid-19th century. The largest paddle-steamer ever built was Brunel's Great Eastern , but it also had screw propulsion and sail rigging. It was 692 ft (211 m) long and weighed 32,000 tons, its paddlewheels being 56 ft (17 m) in diameter. In oceangoing service, paddle steamers became much less useful after

3720-697: The BIWTC once a week. This was a reduction from daily trips, and commercial services were eventually stopped altogether due to safety concerns, operational losses, and a lack of passengers, especially following the inauguration of the Padma Bridge . The first seagoing trip of a paddle steamer was by the Albany in 1808. It steamed from the Hudson River along the coast to the Delaware River . This

3813-510: The Mississippi . Recessed or inboard paddlewheel boats were designed to ply narrow and snag-infested backwaters. By recessing the wheel within the hull it was protected somewhat from damage. It was enclosed and could be spun at a high speed to provide acute maneuverability. Most were built with inclined steam cylinders mounted on both sides of the paddleshaft and timed 90 degrees apart like a locomotive, making them instantly reversing. In

The Art Collections were renamed the Art Museum , which eventually became the Victoria and Albert Museum. When Queen Victoria laid the foundation stone for the new building for the Art Museum, she stipulated that the museum be renamed after herself and her late husband . This was initially applied to

4092-543: The Seine, between Paris and Le Havre. The first paddle-steamer to make a long ocean voyage crossing the Atlantic Ocean was SS  Savannah , built in 1819 expressly for this service. Savannah set out for Liverpool on May 22, 1819, sighting Ireland after 23 days at sea. This was the first powered crossing of the Atlantic, although Savannah was built as a sailing ship with a steam auxiliary; she also carried

4185-689: The United Kingdom, the Science Museum does not charge visitors for admission, although visitors are requested to make a donation if they are able. Temporary exhibitions may incur an admission fee. It is one of the five museums in the Science Museum Group . The museum was founded in 1857 under Bennet Woodcroft from the collection of the Royal Society of Arts and surplus items from the Great Exhibition as part of

4278-624: The United States from the 1820s–1850s, as they were economical and did not incur licensing costs imposed by the steam navigation monopoly. In the 1850s, they were replaced by steamboats. After the American Civil War, as the expanding railroads took many passengers, the traffic became primarily bulk cargoes. The largest, and one of the last, paddle steamers on the Mississippi was the sternwheeler Sprague . Built in 1901, she pushed coal and petroleum until 1948. In Europe from

4836-418: The development of the propeller – which was more efficient and less vulnerable to cannon fire. One of the first screw-driven warships, HMS  Rattler  (1843) , demonstrated her superiority over paddle steamers during numerous trials, including one in 1845 where she pulled a paddle-driven sister ship backwards in a tug of war . However, paddle warships were used extensively by the Russian Navy during

4929-401: The dock, passengers moved to the side of the ship ready to disembark. The shift in weight, added to independent movements of the paddles, could lead to imbalance and potential capsizing . Paddle tugs were frequently operated with clutches in, as the lack of passengers aboard meant that independent paddle movement could be used safely and the added maneuverability exploited to the full. Although

Henry Bell had become interested in steam-propelled boats, and to learn from the Charlotte Dundas venture corresponded with Robert Fulton , who got the North River Steamboat (also known as the Clermont ) into operation in 1807 as the first commercially successful steamboat. In

5115-460: The first sternwheelers were invented in Europe, they saw the most service in North America, especially on the Mississippi River. Enterprise was built at Brownsville, Pennsylvania , in 1814 as an improvement over the less efficient side-wheelers. The second stern-wheeler built, Washington of 1816, had two decks and served as the prototype for all subsequent steamboats of the Mississippi , including those made famous in Mark Twain 's book Life on

5208-458: The goodwill or reputation" of Shell. The museum signed a sponsorship contract with the Norwegian oil and gas company Equinor which contained a gagging clause, stating the museum would not say anything that could damage the fossil fuel company's reputation. The museum's director, Ian Blatchford , defended the museum's sponsorship policy, saying: "Even if the Science Museum were lavishly publicly funded I would still want to have sponsorship from

The survey found that the wooden hull of the replica is in such bad condition that it is beyond economic repair, and recommended that

6789-790: The paddles at different speeds, and even in opposite directions. This extra maneuverability makes side-wheelers popular on the narrower, winding rivers of the Murray–Darling system in Australia, where a number still operate. European sidewheelers, such as PS  Waverley , connect the wheels with solid drive shafts that limit maneuverability and give the craft a wide turning radius. Some were built with paddle clutches that disengage one or both paddles so they can turn independently. However, wisdom gained from early experience with sidewheelers deemed that they be operated with clutches out, or as solid-shaft vessels. Crews noticed that as ships approached

6882-490: The provinces by the Tang dynasty (618–907) emperor. The Chinese Song dynasty (960–1279) issued the construction of many paddle-wheel ships for its standing navy , and according to the British biochemist, historian, and sinologist Joseph Needham : "...between 1132 and 1183 (AD) a great number of treadmill-operated paddle-wheel craft, large and small, were built, including sternwheelers and ships with as many as 11 paddle-wheels

6975-440: The public, it allows free access to almost 7,000 volumes, which can be consulted on site. The Science Museum has been sponsored by major organisations including Shell , BP , Samsung and GlaxoSmithKline . Some have been controversial. The museum declined to give details of how much it receives from oil and gas sponsors. Equinor is also the title sponsor of "Wonderlab: The Equinor Gallery", an exhibition for children, while BP

7068-731: The southern rivers. In 1958, Pakistan River Steamers inherited the fleet, some of which were built at the private Garden Rich Dockyard in Kolkata . After the liberation of Bangladesh , there were around 13 paddle steamers in 1972, nicknamed “the Rockets” for their speed, operated by the newly founded Bangladesh Inland Water Transport Corporation (BIWTC). These included PS Sandra , PS Lali , PS Mohammed , PS Gazi , PS Kiwi , PS Ostrich , PS Mahsud , PS Lepcha , and PS Tern . The steamers served destinations such as Chandpur , Barisal , Khulna , Morrelganj , and Kolkata , from Dhaka . In

7161-535: The start of the First World War , the Royal Navy requisitioned more than fifty pleasure paddle steamers for use as auxiliary minesweepers . The large spaces on their decks intended for promenading passengers proved to be ideal for handling the minesweeping booms and cables, and the paddles allowed them to operate in coastal shallows and estuaries. These were so successful that a new class of paddle ships,

7254-403: The threshold of her own home." Bell built another vessel, Comet II , but on 21 October 1825 she collided with the steamer Ayr off Kempock Point, Gourock , Scotland. The Ayr , we learn, had a light out upon her bow, but the Comet had none. As the night, however, was clear, it is obvious that a bad look out had been kept up, and most reprehensible neglect shown on both sides. At the moment

7347-618: The vessel shall leave the Broomielaw on Tuesdays, Thursdays, and Saturdays about mid-day, or such hour thereafter as may answer from the state of the tide, and to leave Greenock on Mondays, Wednesdays, and Fridays in the morning to suit the tide. On 15 August Comet made the first commercial sailing from Glasgow for Bowling , Helensburgh and Greenock, opening the era of the steamboat on the Clyde, and more widely in Britain and Europe. The fare

7440-505: The wheel travels under water. An engine rotates the paddle wheel in the water to produce thrust , forward or backward as required. More advanced paddle-wheel designs feature "feathering" methods that keep each paddle blade closer to vertical while in the water to increase efficiency. The upper part of a paddle wheel is normally enclosed in a paddlebox to minimise splashing. The three types of paddle wheel steamer are sidewheeler, with one paddlewheel amidships on each side; sternwheeler, with

7533-480: The whole museum, but when that new building finally opened ten years later, the title was confined to the Art Collections and the Science Collections had to be divorced from it. On 26 June 1909 the Science Museum, as an independent entity, came into existence. The Science Museum's present quarters, designed by Sir Richard Allison , were opened to the public in stages over the period 1919–28. This building

7626-444: The winter of 1811/1812 Bell got John and Charles Wood of John Wood and Company , shipbuilders of Port Glasgow , to build a paddle steamer which was named Comet , named after the " Great Comet " of 1811. The 28 ton burthen craft had a deck 43.5 feet (13.3 m) long with a beam of 11.25 feet (3.43 m). It had two paddle wheels on each side, driven by a single-cylinder engine rated at 3 to 4 horsepower (2 to 3 kilowatts). The engine

7719-423: Was "four shillings for the best cabin, and three shillings for the second." As the vessel clearly had no cabins in the modern sense it is unclear what this meant. The success of this service quickly inspired competition, with services down the Firth of Clyde and the sea lochs to Largs , Rothesay , Campbeltown and Inveraray within four years, and the Comet was outclassed by newer steamers. Bell briefly tried

7812-456: Was built by the Science Museum and its main part completed in 1991, to celebrate 200 years since Babbage's birth, and was designed by Zaha Hadid Architects . The Information Age gallery has exhibits covering the development of communications and computing over the last two centuries. It explores the six networks that have transformed global communications: The Cable, The Telephone Exchange, Broadcast, The Constellation, The Cell and The Web It

7905-558: Was criticised by some scientists, including Richard Dawkins , but supported by other scientists, including Steven Rose . The museum has undergone many changes in its history with older galleries being replaced by new ones. Blythe House, 1979–2019, the museum's former storage facility in West Kensington , while not a gallery, it offered tours of the collections housed there. Objects formerly housed there are being transferred to

7998-727: Was hugely expensive in terms of lives, with the Nazis using slave labour to manufacture these rockets". Stephenson's Rocket used to be displayed in this gallery. After a short UK tour, since 2019 Rocket is on permanent display at the National Railway Museum in York, in the Art Gallery. The Medicine: The Wellcome Galleries is a five-gallery medical exhibition which spans ancient history to modern times with over 3000 exhibits and specially commissioned artworks. Many of

8091-533: Was known as the East Block, construction of which began in 1913 and was temporarily halted by World War I . As the name suggests it was intended to be the first building of a much larger project, which was never realized. However, the museum buildings were expanded over the following years; a pioneering Children's Gallery with interactive exhibits opened in 1931, the Centre Block was completed in 1961–3,

8184-545: Was lengthened, made a schooner, and was run on the Larne trade, where she was at great favourite, and was familiarly called the 'Long Ann'. Some time since she was burnt down to the waters edge, but her hull was so good, and she was such a favourite with her owners, that they hauled her into dock and fitted her. The curious thing is, that having been built at Port-Glasgow 63 years ago, and undergoing many vicissitudes, she should, like an old weather-beaten sailor, end her days almost at

8277-509: Was made by John Robertson of Glasgow, and the boiler by David Napier , Camlachie , Glasgow (a story has it that they were evolved from an experimental little steam engine which Bell installed to pump sea water into the Helensburgh Baths). The funnel was tall and thin, serving as a mast, with a yard , allowing it to support a square sail when there was a following wind. A small cabin aft had wooden seats in front of concealed beds and

8370-466: Was opened on 24 October 2014 by the Queen, Elizabeth II , who sent her first tweet from here. One of the most popular galleries in the museum is the interactive Wonderlab:The Equinor Gallery , formerly called Launchpad . The gallery is staffed by Explainers who demonstrate how exhibits work, conduct live experiments and perform shows to schools and the visiting public. The Flight gallery charts

8463-416: Was purely for the purpose of moving a river-boat to a new market, but paddle-steamers began regular short coastal trips soon after. In 1816 Pierre Andriel, a French businessman, bought in London the 15  hp (11 kW) paddle steamer Margery (later renamed Elise ) and made an eventful London- Le Havre -Paris crossing, encountering heavy weather on the way. He later operated his ship as a river packet on

8556-650: Was steamed from Newcastle to San Francisco. As the voyage was intended to be completed under power, the tug was rigged as steam propelled with a sail auxiliary. The transatlantic stage of the voyage was completed exactly 150 years after the voyage of Savannah . As of 2022, the PS Waverley is the last seagoing passenger-carrying paddle steamer in the world. Beginning in the 1820s, the British Royal Navy began building paddle-driven steam frigates and steam sloops . By 1850 these had become obsolete due to

8649-463: Was the first commercial paddle steamer and steamboat , the first commercial success was possibly Robert Fulton 's Clermont in New York, which went into commercial service in 1807 between New York City and Albany . Many other paddle-equipped river boats followed all around the world; the first in Europe being PS  Comet designed by Henry Bell which started a scheduled passenger service on
