Rangitoto Lighthouse
Rangitoto Lighthouse (also called Rangitoto Beacon) is a lighthouse off the coast in McKenzie Bay, in Auckland's Hauraki Gulf. The lighthouse was built in 1882. In 1905 a light was added for nighttime visibility. Although not classed officially as a lighthouse by the New Zealand MSA, it does currently flash red every 12 seconds (also known as its character) and can be seen clearly from the southernmost of North Harbour's East Coast Bays. The beacon is red and white in colour, stands at tall, and continues to run through solar power. The height of the focal plane is .

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maritime New Zealand
Maritime New Zealand (New Zealand Maritime Safety Authority) is a Crown entity and also a state maritime safety authority responsible for protecting the maritime transport sequence and marine environment within New Zealand and maintaining safety and security. They define their vision as: "a maritime environment with minimum deaths, accidents, incidents and pollution as part of an integrated and sustainable transport system”. Maritime New Zealand supports people by providing guidance and advice about Seafarer Certifications as well. History A maritime authority called the Marine Board was originally established in 1862 and controlled by the Customs Department until near the end of the nineteenth century, when it was renamed the Marine Department. In 1907 the Marine Department acquired the 805 ton Royal Navy gun boat HMS ''Sparrow''. This was converted into a training ship and renamed NZS ''Amokura''. Over the next 14 years 527 boys trained in ''Amokura'', 25 of them going o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Coast Bays
East Coast Bays is a string of small suburbs that form the northernmost part of the North Shore, part of the contiguous Auckland metropolitan area in New Zealand. The suburbs line the north-east coast of the city along the shore of the Hauraki Gulf and Rangitoto Channel. They stretch from Long Bay in the north to Castor Bay in the south. They include, from north to south, Long Bay, Torbay, Waiake Bay, Browns Bay, Rothesay Bay, Murrays Bay, Mairangi Bay, Campbells Bay and Castor Bay. History The land within the modern-day district was originally part of the Mahurangi Block, which extended from Te Arai in the north, all the way to North Head to the south. The land in the district was claimed by several Maōri tribes, through a series of conquests and marriages. Most settlers in the European settlement of New Zealand established farms in the flat lands of the bays. With opening of the Auckland Harbour Bridge in 1954, the district experienced rapid growth of populati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new generation capacity being solar in 2021. ...

Focal Plane
In Gaussian optics, the cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system. These are the '' focal points'', the principal points, and the nodal points. For ''ideal'' systems, the basic imaging properties such as image size, location, and orientation are completely determined by the locations of the cardinal points; in fact only four points are necessary: the focal points and either the principal or nodal points. The only ideal system that has been achieved in practice is the plane mirror, however the cardinal points are widely used to ''approximate'' the behavior of real optical systems. Cardinal points provide a way to analytically simplify a system with many components, allowing the imaging characteristics of the system to be approximately determined with simple calculations. Explanation The cardinal points lie on the optical axis of the optical system. Each point is defined by the effect the opti ...
