Ram Island Ledge Light
Ram Island Ledge Light is a lighthouse in Casco Bay, Maine, United States, marking the northern end of the main channel leading the harbor of Portland, Maine. History The Ram Island Ledges are a series of stone ledges, some of which break the waters at the southern end of Casco Bay, a short way south of Cushing Island. In 1855 an iron spindle was erected to protect sailors from these dangerous underwater ledges. The ledge continued to be the site of repeated shipwrecks. On February 24, 1900, the Allan Line steamship ''Californian'' (formerly named the ''State of California'') ran aground on the ledge while en route from Portland to Glasgow, Scotland via Halifax, Nova Scotia. As a result of that accident, the United States Congress appropriated funds to build a lighthouse. Construction began on May 1, 1903, and was completed in 1905. It is a twin of the Graves Light off Boston. The lighthouse was built of granite quarried from Vinalhaven, Maine. The lighthouse originall ...

Port Of Portland (Maine)
The Port of Portland is a seaport located in Portland, Maine. It is the second-largest tonnage seaport in New England as well as one of the largest oil ports on the East Coast (the second-largest prior to 2016). It is the primary American port of call for Icelandic shipping company Eimskip. There are nine terminals in the port according to the Maine Port Authority, a statewide agency that oversees Maine's commercial marine facilities. Additionally there are two passenger facilities, the Ocean Gateway International Marine Passenger Terminal and the Casco Bay Ferry Terminal. The majority of Portland's non-passenger terminals are for petroleum products, especially the Portland–Montreal pipeline, which has gradually reduced its capacity since 2010. Container shipping through Portland has increased considerably over that same period. 100 cruise ships docked in Portland in 2019, making it Maine's second-largest cruise ship port behind Bar Harbor.

Lighthouses On The National Register Of Historic Places In Maine
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 the advent of much cheaper, more sophisticated, and more 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 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 and promontories, unlike many moder ...

Solar Power
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. 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 (PV) 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 panels has fallen, grid-connected solar PV systems' capacity and production has doubled about every three years. Three-quarters of new generation capacity is solar, with both millions of rooftop installatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
