Solar car racing refers to competitive races of electric vehicles which are powered by solar energy obtained from solar panels on the surface of the car ( solar cars ). The first solar car race was the Tour de Sol in 1985 which led to several similar races in Europe, US and Australia. Such challenges are often entered by universities to develop their students' engineering and technological skills, but many business corporations have entered competitions in the past. A small number of high school teams participate in solar car races designed exclusively for high school students.
126-572: The Solar Car Challenge is an annual solar-powered car race for high school students. The event attracts teams from around the world, but mostly from American high schools. The race was first held in 1995. Each event is the end product of a two-year education cycle launched by the Winston Solar Car Team. On odd-numbered years, the race is a road course that starts at the Texas Motor Speedway , Fort Worth , Texas ;
252-449: A Halbach array configuration for the neodymium-iron-boron magnets, and Litz wire for the windings. Cheaper alternatives are asynchronous AC or brushed DC motors. The mechanical systems are designed to keep friction and weight to a minimum while maintaining strength and stiffness. Designers normally use aluminium, titanium and composites to provide a structure that meets strength and stiffness requirements whilst being fairly light. Steel
378-519: A counterweight to the known landmasses in the Northern Hemisphere. The cartographic depictions of the southern continent in the 16th and early 17th centuries, as might be expected for a concept based on such abundant conjecture and minimal data, varied wildly from map to map; in general, the continent shrank as potential locations were reinterpreted. At its largest, the continent included Tierra del Fuego , separated from South America by
504-481: A multicultural country . Sydney is the most multicultural city in Oceania, having more than 250 different languages spoken, with about 40 percent of residents speaking a language other than English at home. Furthermore, 36 percent of the population reported having been born overseas , with top countries being Italy , Lebanon , Vietnam and Iraq , among others. Melbourne is also fairly multicultural, having

Workshops, curriculum materials, DVDs, and on-site visits have introduced the challenge to over 1100 schools across 20 countries. This initiative continues to inspire the next generation of innovators in renewable energy technology. The 2007 The Solar Car Challenge was featured on CNN affiliate KLTV . The Solar Car Challenge
756-634: A car or boat. This event is currently held at ScienceWorks ( Melbourne ) in October each year. The first event was held in 1986. The goal of the challenge is to provide students with an experience of what it is like to work in STEM and to understand what can be achieved with renewable technology . Junior Solar Sprint was created in the 1980s by the National Renewable Energy Laboratory (NREL) to teach younger children about
882-771: A continent in the book, but did note that it was one of the six major divisions of the world. He considered it to encompass the insular Pacific area between Asia and the Americas, and claimed it extended up to the Aleutian Islands , which are among the northernmost islands in the Pacific Ocean. However, definitions of Oceania varied during the 19th century. In the 19th century, many geographers divided up Oceania into mostly racially-based subdivisions; Australasia , Malaysia (encompassing Malay Archipelago ) , Melanesia , Micronesia and Polynesia . Today,
1008-413: A large equation (approximately 100 terms). Using the power equation as the arbiter, vehicle designers can compare various car designs and evaluate the comparative performance over a given route. Combined with CAE and systems modeling, the power equation can be a useful tool in solar car design. The directional orientation of a solar car race route affects the apparent position of the sun in the sky during
1134-492: A long-standing ally of the United States when threatened by Imperial Japan during World War II . Trade with Asia increased and a post-war immigration program received more than 6.5 million migrants from every continent. Supported by immigration of people from more than 200 countries since the end of World War II, the population increased to more than 23 million by 2014. For about 40 million years Australia–New Guinea
1260-404: A race day, which in turn affects the energy input to the vehicle. This is significant to designers, who seek to maximize energy input to a panel of solar cells (often called an "array" of cells) by designing the array to point directly toward the sun for as long as possible during the race day. Thus, a south-north race car designer might increase the car's total energy input by using solar cells on
1386-424: A rigorous qualifying process known as "Scrutineering" to ensure compliance with safety and technical regulations. Each solar car is equipped with essential safety features including roll cages, safety harnesses, communication systems, and fire extinguishers.

There are two major political groups that usually form government, federally and in the states: the Australian Labor Party and
1638-582: A single battery charge. This particular record was overseen by the Confederation of Australian Motorsport on behalf of the FIA and is not exclusive to solar-powered cars but to any electric car, and so during the attempt, the solar panels were disconnected from the electrical systems. The previous record of 73 kilometres per hour (45 mph) - which had been set in 1988 - was broken by the team with an average speed of 107 kilometres per hour (66 mph) over
1764-569: A small strait; New Guinea ; and what would come to be called Australia. In 1606, Dutch navigator Willem Janszoon made the first documented European sight and landing on the continent of Australia in Cape York Peninsula . Dutch explorer Abel Janszoon Tasman circumnavigated and landed on parts of the Australian continental coast and discovered Van Diemen's Land (now Tasmania ), New Zealand in 1642, and Fiji islands. He
1890-512: A typical day on the WSC. Some cars have employed free-standing or integrated sails to harness wind energy. Races including the WSC and ASC , consider wind energy to be solar energy, so their race regulations allow this practice. Aerodynamic drag is the main source of losses on a solar race car. The aerodynamic drag of a vehicle is the product of the frontal area and its C d . For most solar cars
2016-615: A unique fauna , flora and mycobiota developed. Marsupials and monotremes also existed on other continents, but only in Australia–New Guinea did they out-compete the placental mammals and come to dominate. New Guinea has 284 species and six orders of mammals: monotremes, three orders of marsupials, rodents and bats ; 195 of the mammal species (69%) are endemic. New Guinea has a rich diversity of coral life and 1,200 species of fish have been found. Also about 600 species of reef-building coral—the latter equal to 75 percent of
2142-413: A variety of solar cell technologies; most often polycrystalline silicon, mono-crystalline silicon, or gallium arsenide. The cells are wired together into strings while strings are often wired together to form a panel. Panels normally have voltages close to the nominal battery voltage. The main aim is to get as much cell area in as small a space as possible. Designers encapsulate the cells to protect them from
2268-454: Is a small canopy in the middle of a curved wing-like array, entirely covered in cells, with 3 wheels. Before, the cockroach style with a smooth nose fairing into the panel was more successful. At lower speeds, with less powerful arrays, other configurations are viable and easier to construct, e.g. covering available surfaces of existing electric vehicles with solar cells or fastening solar canopies above them. The electrical system controls all of
2394-504: Is an English creole language spoken in Papua New Guinea. Papua New Guinea has more languages than any other country, with over 820 indigenous languages, representing 12% of the world's total, but most have fewer than 1,000 speakers. Since 1945, more than 7 million people have settled in Australia. From the late 1970s, there was a significant increase in immigration from Asian and other non-European countries, making Australia
2520-580: Is associated with seasonal abnormality in many areas in the world. Australia is one of the continents most affected and experiences extensive droughts alongside considerable wet periods. Christianity is the predominant religion in the continent, although large proportions of Australians belong to no religion . Other religions in the region include Islam , Buddhism and Hinduism , which are prominent minority religions in Australia. Traditional religions are often animist , found in New Guinea. Islam

This includes mainland Australia , Tasmania , and the island of New Guinea , which comprises Papua New Guinea and Western New Guinea (Papua and West Papua, provinces of Indonesia ). The name "Sahul" takes its name from
3276-776: Is the double wishbone suspension . The rear suspension is often a trailing-arm suspension as found in motorcycles. Solar cars are required to meet rigorous standards for brakes. Disc brakes are the most commonly used due to their good braking ability and ability to adjust. Mechanical and hydraulic brakes are both widely used. The brake pads or shoes are typically designed to retract to minimize brake drag, on leading cars. Steering systems for solar cars also vary. The major design factors for steering systems are efficiency, reliability and precision alignment to minimize tire wear and power loss. The popularity of solar car racing has led to some tire manufacturers designing tires for solar vehicles. This has increased overall safety and performance. All
3402-740: Is the highest mountain . The Australian continent and Sunda were points of early human migrations after leaving Africa. Recent research points to a planned migration of hundreds of people using bamboo rafts, which eventually landed on Sahul. Indigenous Australians , that is Aboriginal Australians and Torres Strait Islanders people, are the original inhabitants of the Australian continent and nearby islands. They migrated from Africa to Asia around 70,000 years ago and arrived in Australia at least 50,000 years ago, based on archaeological evidence. More recent research points to earlier arrival, possibly 65,000 years ago. They are believed to be among
3528-649: Is the smallest of the seven traditional continents . The continent includes a continental shelf overlain by shallow seas which divide it into several landmasses—the Arafura Sea and Torres Strait between mainland Australia and New Guinea, and Bass Strait between mainland Australia and Tasmania. When sea levels were lower during the Pleistocene ice age , including the Last Glacial Maximum about 18,000 BC, they were connected by dry land into

3780-448: Is too often confused with Australia ." Some 19th century definitions of Oceania grouped Australia, New Zealand and the islands of Melanesia together under the label of Australasia , in other 19th century definitions of Oceania, the term was only used to refer to Australia itself, with New Zealand being categorized with the islands of Polynesia in such definitions. Archaeological terminology for this region has changed repeatedly. Before
3906-471: Is used for some suspension parts on many cars. Solar cars usually have three wheels, but some have four. Three-wheelers usually have two front wheels and one rear wheel: the front wheels steer and the rear wheel follows. Four-wheel vehicles are set up like normal cars or similarly to three-wheeled vehicles with the two rear wheels close together. Solar cars have a wide range of suspensions because of varying bodies and chassis. The most common front suspension

5292-634: The Sahul Shelf and Bass Strait . Geological forces such as tectonic uplift of mountain ranges or clashes between tectonic plates occurred mainly in Australia's early history, when it was still a part of Gondwana . Australia is situated in the middle of the tectonic plate, and therefore currently has no active volcanism. The continent primarily sits on the Indo-Australian Plate. Because of its central location on its tectonic plate, Australia does not have any active volcanic regions,
5418-548: The Sahul Shelf , which is part of the continental shelf of the Australian continent. The term Oceania , originally a "great division" of the world in the 1810s, was replaced in English language countries by the concept of Australia as one of the world's continents in the 1950s. Prior to the 1950s, before the popularization of the theory of plate tectonics , Antarctica , Australia and Greenland were sometimes described as island continents, but none were usually taught as one of

9450-415: The financial year 2014/15, tourism represented 3.0% of Australia 's GDP contributing A$ 47.5 billion to the national economy. In 2015, there were 7.4 million visitor arrivals. Mercer Quality of Living Survey ranks Sydney tenth in the world in terms of quality of living , making it one of the most livable cities . It is classified as an Alpha+ World City by GaWC . Melbourne also ranked highly in
9576-629: The first European to explore the Strait. When Europeans first arrived, inhabitants of New Guinea and nearby islands, whose technologies included bone, wood, and stone tools, had a productive agricultural system. In 1660, the Dutch recognised the Sultan of Tidore 's sovereignty over New Guinea . The first known Europeans to sight New Guinea were probably the Portuguese and Spanish navigators sailing in
9702-636: The first Solar Race to receive endorsement from these 3 organizations. The last race took place in 2016. Sasol confirmed their support of the South Africa Solar Challenge, by taking naming rights to the event, so that for the duration of their sponsorship, the event was known as the Sasol Solar Challenge, South Africa. The Carrera Solar Atacama is the first solar-powered car race of its kind in Latin America;
9828-450: The frontal area is 0.75 to 1.3 m . While C d as low as 0.10 have been reported, 0.13 is more typical. This needs a great deal of attention to detail. The vehicle's mass is also a significant factor. A light vehicle generates less rolling resistance and will need smaller lighter brakes and other suspension components. This is the virtuous circle when designing lightweight vehicles. Rolling resistance can be minimized by using
9954-495: The globe. Animal groups such as macropods , monotremes , and cassowaries are endemic to Australia. There were three main reasons for the enormous diversity that developed in animal, fungal and plant life. Although New Guinea is the most northerly part of the continent, and could be expected to be the most tropical in climate, the altitude of the New Guinea highlands is such that a great many animals and plants that were once common across Australia–New Guinea now survive only in
10080-481: The high and rugged mountains of New Guinea and, by reverse (downwards) buckling, the Torres Strait that now separates the two main landmasses. The collision also pushed up the islands of Wallacea , which served as island 'stepping-stones' that allowed plants from Southeast Asia 's rainforests to colonise New Guinea, and some plants from Australia–New Guinea to move into Southeast Asia. The ocean straits between
10206-570: The importance and challenges of using renewable energy . The project also teaches students how the engineering process is applied, and how solar panels , transmission , and aerodynamics can be used in practice. The FIA recognise a land speed record for vehicles powered only by solar panels. The current record was set by the Solar Team Twente , of the University of Twente with their car SolUTra. The record of 37.757 km/h
10332-439: The inaugural Cruiser Class winner with their vehicle Stella . The American Solar Challenge, previously known as the 'North American Solar Challenge' and 'Sunrayce', features mostly collegiate teams racing in timed intervals in the United States and Canada. The annual Formula Sun Grand Prix track race is used as a qualifier for ASC. The American Solar Challenge was sponsored in part by several small sponsors. However, funding
10458-461: The islands were narrow enough to allow plant dispersal, but served as an effective barrier to exchange of land mammals between Australia–New Guinea and Asia. Among the fungi, the remarkable association between Cyttaria gunnii (one of the "golf-ball" fungi) and its associated trees in the genus Nothofagus is evidence of that drift: the only other places where this association is known are New Zealand and southern Argentina and Chile . Due to
10584-477: The largest Greek-speaking population outside of Europe , and the second largest Asian population in Australia after Sydney. Australia is the only First World country on the Australia-New Guinea continent, although the economy of Australia is by far the largest and most dominant economy in the region and one of the largest in the world. Australia's per-capita GDP is higher than that of
10710-650: The last 6 times it has been held. The Solar Car Challenge is an annual event that fosters education and innovation in renewable energy by engaging high school students in the design, engineering, and racing of solar-powered vehicles. Founded in 1989 by Dr. Lehman Marks, the challenge has grown to become a premier educational program, combining science, technology, engineering, and mathematics (STEM) principles with hands-on experience. Participants are tasked with building and racing solar cars, allowing them to apply theoretical knowledge to practical problems while promoting sustainable technology and teamwork. Held over several days,
10836-695: The legislature, rather than chosen by the executive branch. Since 1788, the primary influence behind Australian culture has been Anglo-Celtic Western culture , with some Indigenous influences. The divergence and evolution that has occurred in the ensuing centuries has resulted in a distinctive Australian culture. Since the mid-20th century, American popular culture has strongly influenced Australia, particularly through television and cinema. Other cultural influences come from neighbouring Asian countries, and through large-scale immigration from non-English-speaking nations. The Australian Museum in Sydney and
10962-541: The long-established broad-leaf deciduous forest began to give way to the distinctive hard-leaved sclerophyllous plants that characterise the modern Australian landscape. Typical Southern Hemisphere flora include the conifers Podocarpus (eastern Australia and New Guinea), the rainforest emergents Araucaria (eastern Australia and New Guinea), Nothofagus (New Guinea and Tasmania ) and Agathis (northern Queensland and New Guinea), as well as tree ferns and several species of Eucalyptus . Prominent features of
11088-616: The mainland. Then between about 8,000 and 6,500 BC, the lowlands in the north were flooded by the sea, separating the Aru Islands , mainland Australia, New Guinea , and Tasmania. A northern arc consisting of the New Guinea Highlands , the Raja Ampat Islands , and Halmahera was uplifted by the northward migration of Australia and subduction of the Pacific Plate . The Outer Banda Arc was accreted along
11214-487: The name Australinea in 2004. Australia–New Guinea has also been used. The Australian continent, as a whole being part of the Australian Plate , is the lowest, flattest, and oldest landmass on Earth and it has had a relatively stable geological history. New Zealand is not part of the continent of Australia, but of the separate, submerged continent of Zealandia . New Zealand and Australia are both part of
11340-550: The name Sahul was extended from its previous use for just the Sahul Shelf to cover the continent. In 1984, the name Meganesia was suggested, meaning "great island" or "great island-group", for both the Pleistocene continent and the present-day lands, and this name has been widely accepted by biologists. Others have used Meganesia with different meanings: travel writer Paul Theroux included New Zealand in his definition and others have used it for Australia, New Zealand and Hawaii . Another biologist, Richard Dawkins , coined
11466-432: The name of Oceania. There are thus six great divisions of the earth — Europe , Asia , Africa , North America, South America and Oceania." The American author Samuel Griswold Goodrich wrote in his 1854 book History of All Nations that, "geographers have agreed to consider the island world of the Pacific Ocean as a third continent, under the name Oceania." In this book the other two continents were categorized as being
11592-608: The naval air base HMAS Albatross in Nowra , breaking the record previously held by the General Motors car Sunraycer of 78.3 kilometres per hour (48.7 mph). The record takes place over a flying 500 metres (1,600 ft) stretch, and is the average of two runs in opposite directions. The Perth to Sydney Transcontinental record has held a certain allure in Solar Car Racing. Hans Tholstrup (the founder of
11718-511: The northwestern edge the continent; it includes the islands of Timor , Tanimbar , and Seram . Papua New Guinea has several volcanoes , as it is situated along the Pacific Ring of Fire . Volcanic eruptions are not rare, and the area is prone to earthquakes and tsunamis because of this. Mount Wilhelm in Papua New Guinea is the second highest mountain in the continent, and at 4,884 metres (16,024 ft) above sea level , Puncak Jaya
11844-407: The only continent with this distinction. The lands were joined with Antarctica as part of the southern supercontinent Gondwana until the plate began to drift north about 96 million years ago. For most of the time since then, Australia–New Guinea remained a continuous landmass. When the last glacial period ended in about 10,000 BC, rising sea levels formed Bass Strait , separating Tasmania from
11970-414: The potential of solar energy but also inspires the next generation of engineers, scientists, and environmentally-conscious citizens. The South African Solar Challenge is a biennial, two-week solar-powered car race through the length and breadth of South Africa. The first challenge in 2008 proved that this event can attract the interest of the public, and that it has the necessary international backing from
12096-409: The power entering and leaving the system. The battery pack stores surplus solar energy produced when the vehicle is stationary or travelling slowly or downhill. Solar cars use a range of batteries including lead-acid batteries , nickel-metal hydride batteries ( NiMH ), nickel-cadmium batteries ( NiCd ), lithium ion batteries and lithium polymer batteries . Power electronics may be used to optimize
12222-535: The primary refuge was the relatively cool and well-watered Great Dividing Range . Even today, pockets of remnant vegetation remain in the cool uplands, some species not much changed from the Gondwanan forms of 60 or 90 million years ago. Eventually, the Australia–New Guinea tectonic plate collided with the Eurasian plate to the north. The collision caused the northern part of the continent to buckle upwards, forming
12348-556: The race covers 2,600 km (1,600 mi) from Santiago to Arica in the north of Chile. The race's founder, La Ruta Solar, claims it is the most extreme of the vehicular races due to the high levels of solar radiation, up to 8.5 kWh/m /day, encountered while traversing the Atacama Desert, as well as challenging participating teams to climb 3,500 m (11,500 ft) above sea level. After the 2018 race, La Ruta Solar organized its next edition for 2020, but it never came to be. In
12474-400: The right tires, inflated to the right pressure, correctly aligned, and by minimizing the weight of the vehicle. The design of a solar car is governed by the following work equation: which can be usefully simplified to the performance equation for long-distance races, and values seen in practice. Briefly, the left-hand side represents the energy input into the car (batteries and power from
12600-543: The seventh century, and archipelagic rule of New Guinea by the 13th. At the beginning of the seventh century, the Sumatra -based empire of Srivijaya (7th century–13th century) engaged in trade relations with western New Guinea, initially taking items like sandalwood and birds-of-paradise in tribute to China , but later making slaves out of the natives. The rule of the Java -based empire of Majapahit (1293–1527) extended to
12726-399: The sides of the vehicle where the sun will strike them (or by creating a convex array coaxial with the vehicle's movement). In contrast, an east-west race alignment might reduce the benefit from having cells on the side of the vehicle, and thus might encourage design of a flat array. Because solar cars are often purpose-built, and because arrays do not usually move in relation to the rest of
12852-530: The speed limit (110 km/h) in previous years. In 2013 the organisers of the event introduced the Cruiser Class to the World Solar Challenge, designed to encourage contestants to design a "practical" solar powered vehicle. This race requires that vehicles have four wheels and upright seating for passengers, and is judged on a number of factors including time, payload, passenger miles, and external energy use. The Dutch TU Eindhoven solar racing team were
12978-565: The spread of animals, fungi and plants across the single Pleistocene landmass the separate lands have a related biota . There are over 300 bird species in West Papua , of which at least 20 are unique to the ecoregion, and some live only in very restricted areas. These include the grey-banded munia , Vogelkop bowerbird , and the king bird-of-paradise . Australia has a huge variety of animals; some 83% of mammals , 89% of reptiles , 24% of fish and insects and 93% of amphibians that inhabit
13104-526: The string of cells, allowing current around the non-functioning cell(s). Another consideration is that the battery itself can force current backward through the array unless there are blocking diodes put at the end of each panel. The power produced by the solar array depends on the weather conditions, the position of the sun and the capacity of the array. At noon on a bright day, a good array can produce over 2 kilowatts (2.6 hp). A 6 m array of 20% cells will produce roughly 6 kW·h (22 kJ) of energy during
13230-407: The sun) and the right-hand side is the energy needed to drive the car along the race route (overcoming rolling resistance, aerodynamic drag, going uphill and accelerating). Everything in this equation can be estimated except v . The parameters include: Note 1 For the WSC the average panel power can be approximated as (7/9)×nominal power. Solving the long form of the equation for velocity results in
13356-527: The tone for the bitter final stages of the New Guinea campaign , which persisted into 1945. The offensives in Papua and New Guinea of 1943–44 were the single largest series of connected operations ever mounted by the Australian armed forces. Following the 1998 commencement of reforms across Indonesia , Papua and other Indonesian provinces received greater regional autonomy. In 2001, "Special Autonomy" status
13482-423: The top teams now use wheel motors , eliminating belt or chain drives. Testing is essential to demonstrating vehicle reliability prior to a race. It is easy to spend a hundred thousand dollars to gain a two-hour advantage, and equally easy to lose two hours due to reliability issues. The solar array consists of hundreds (or thousands) of photovoltaic solar cells converting sunlight into electricity. Cars can use
13608-558: The tropical highlands where they are severely threatened by population growth . In New Guinea, the climate is mostly monsoonal (December to March), southeast monsoon (May to October), and tropical rainforest with slight seasonal temperature variation. In lower altitudes, the temperature is around 27 °C (81 °F) year round. But the higher altitudes, such as Mendi , are constantly around 21 °C (70 °F) with cool lows nearing 11 °C (52 °F), with abundant rainfall and high humidity. The New Guinea Highlands are one of
13734-415: The vehicle (with notable exceptions), this race-route-driven, flat-panel versus convex design compromise is one of the most significant decisions that a solar car designer must make. Australian continent The continent of Oceania , sometimes known in technical contexts by the names Sahul ( / s ə ˈ h uː l / ), Australia-New Guinea , Australinea , or Meganesia to distinguish it from
13860-470: The weather and breakage. Designing a solar array is more than just stringing a bunch of cells together. A solar array acts like many very small batteries all hooked together in series. The total voltage produced is the sum of all cell voltages. The problem is that if a single cell is in shadow it acts like a diode , blocking the current for the entire string of cells. To design against this, array designers use by-pass diodes in parallel with smaller segments of
13986-517: The western fringes of New Guinea. Recent archaeological research suggests that 50,000 years ago people may have occupied sites in the highlands at New Guinean altitudes of up to 2,000 m (6,600 ft), rather than being restricted to warmer coastal areas. Legends of Terra Australis Incognita—an "unknown land of the South"—date back to Roman times and before, and were commonplace in medieval geography, although not based on any documented knowledge of
14112-499: The whole electrical system, while basic cars show battery voltage and motor current. In order to judge the range available with varying solar production and motive consumption, an ampere-hour meter multiplies battery current and rate, thus providing the remaining vehicle range at each moment in the given conditions. A wide variety of motor types have been used. The most efficient motors exceed 98% efficiency. These are brushless three-"phase" DC, electronically commutated, wheel motors, with
14238-782: The world". In 1883, the Colony of Queensland tried to annex the southern half of eastern New Guinea, but the British government did not approve. The Commonwealth of Australia came into being when the Federal Constitution was proclaimed by the Governor-General , Lord Hopetoun , on 1 January 1901. From that point a system of federalism in Australia came into operation, entailing the establishment of an entirely new national government (the Commonwealth government) and an ongoing division of powers between that government and
14364-522: The world". In the Pacific Ocean Handbook (1945), author Eliot Grinnell Mears wrote that he categorized Australia, New Zealand and Pacific islands under the label of Oceania for "scientific reasons; Australia's fauna is largely continental in character, New Zealand's are clearly insular; and neither Commonwealth realm has close ties with Asia." He further added that, "the term Australasia is not relished by New Zealanders and this name
14490-532: The world's continents in English-speaking countries. Scottish cartographer John Bartholomew wrote in 1873 that, "the New World consists of North America , and the peninsula of South America attached to it. These divisions [are] generally themselves spoken as continents, and to them has been added another, embracing the large island of Australia and numerous others in the [Pacific] Ocean, under
14616-438: The world's known total. New Guinea has 578 species of breeding birds, of which 324 species are endemic. Bird life also flourished—in particular, the songbirds (order Passeriformes , suborder Passeri) are thought to have evolved 50 million years ago in the part of Gondwana that later became Australia , New Zealand, New Guinea , and Antarctica , before radiating into a great number of different forms and then spreading around
14742-419: The world's oldest known cremations , thus indicating early evidence for religious ritual among humans. Dreamtime remains a prominent feature of Australian Aboriginal art , the oldest continuing tradition of art in the world. Papuan habitation is estimated to have begun between 42,000 and 48,000 years ago in New Guinea. Trade between New Guinea and neighboring Indonesian islands was documented as early as
14868-530: The world. It is also one of the most rural, as only 18 percent of its people live in urban centres. West Papua , a region in Indonesia, is home to an estimated 44 uncontacted tribal groups . Australia, the largest landmass in the continent, is highly urbanised , and has the world's 14th-largest economy with the second-highest human development index globally. Australia also has the world's 9th largest immigrant population . The continent of Oceania
14994-451: Was almost completely isolated. During this time, the continent experienced numerous changes in climate, but the overall trend was towards greater aridity. When South America eventually separated from Antarctica, the development of the cold Antarctic Circumpolar Current changed weather patterns across the world. For Australia–New Guinea, it brought a marked intensification of the drying trend. The great inland seas and lakes dried out. Much of
15120-508: Was cut near the end of 2005, and the NASC 2007 was cancelled. The North American solar racing community worked to find a solution, bringing in Toyota as a primary sponsor for a 2008 race. Toyota has since dropped the sponsorship. The last North American Solar Challenge was run 2016, from Brecksville, OH to Hot Springs, SD. The race was won by the University of Michigan . Michigan has won the race
15246-533: Was granted to Papua province, although to date, implementation has been partial and often criticised. The region was administered as a single province until 2003, when it was split into the provinces of Papua and West Papua . Elections in 1972 resulted in the formation of a ministry headed by Chief Minister Michael Somare , who pledged to lead the country to self-government and then to independence. Papua New Guinea became self-governing on 1 December 1973 and achieved independence on 16 September 1975. The country joined
15372-1031: Was named one of America's 10 most innovative education programs by Business Wire in 2003. Solar car racing The two most notable solar car distance (overland) races are the World Solar Challenge and the American Solar Challenge . They are contested by a variety of university and corporate teams. Corporate teams participate in the races to give their design teams experience of working with both alternative energy sources and advanced materials. University teams participate in order to give their students experience in designing high technology cars and working with environmental and advanced materials technology. These races are often sponsored by government or educational agencies, and businesses such as Toyota keen to promote renewable energy sources. The cars require intensive support teams similar in size to professional motor racing teams. This
15498-492: Was set in 2005. The record takes place over a flying 1000m run, and is the average speed of 2 runs in opposite directions. In July, 2014, a group of Australian students from the UNSW Sunswift solar racing team at the University of New South Wales broke a world record in their solar car, for the fastest electric car weighing less than 500 kilograms (1,100 lb) and capable of travelling 500 kilometres (310 mi) on
15624-516: Was the first known European explorer to reach these islands. In the quest for Terra Australis , Spanish explorations in the 17th century, such as the expedition led by the Portuguese navigator Pedro Fernandes de Queirós , discovered the Pitcairn and Vanuatu archipelagos, and sailed the Torres Strait between Australia and New Guinea , named after navigator Luís Vaz de Torres , who was
15750-666: Was the largest project in PNG's history. Papua New Guinea is classified as a developing economy by the International Monetary Fund . Strong growth in Papua New Guinea's mining and resource sector led to the country becoming the sixth fastest-growing economy in the world in 2011. Australia is a federal parliamentary constitutional monarchy with Charles III at its apex as the King of Australia ,
15876-556: Was the largest single attack ever mounted by a foreign power on Australia. In an effort to isolate Australia, the Japanese planned a seaborne invasion of Port Moresby , in the Australian Territory of New Guinea . Between July and November 1942, Australian forces repulsed Japanese attempts on the city by way of the Kokoda Track , in the highlands of New Guinea . The Battle of Buna–Gona , between November 1942 and January 1943, set
