Konrad Gehringer
Konrad Gehringer (4 June 1939 – 12 December 2003) was a German car mechanic and bus driver who had a one-man operation for producing electronic organs in Pforzheim, Germany. Gehringer was best known as the inventor and developer of the one-man submersible ''Speleonaut'', the first submarine designed for cave diving. The ''Speleonaut'' was designed in collaboration with Gehringer's friend, the cave diver Jochen Hasenmayer, who has used it since 1996 to explore the Blautopf The Blautopf (German for ''Blue pot'') is a spring that serves as the source of the river Blau in the karst landscape on the Swabian Jura's southern edge. It is located in Blaubeuren, Alb-Donau-Kreis, Baden-Württemberg, Germany (approximately w ... cave system.

Electronic Organ
An electric organ, also known as electronic organ, is an electronic keyboard instrument which was derived from the harmonium, pipe organ and theatre organ. Originally designed to imitate their sound, or orchestral sounds, it has since developed into several types of instruments: * Hammond-style organs used in pop, rock and jazz; * digital church organs, which imitate pipe organs and are used primarily in churches; * other types including combo organs, home organs, and software organs. History Predecessors ;Harmonium The immediate predecessor of the electronic organ was the harmonium, or reed organ, an instrument that was common in homes and small churches in the late 19th and early 20th centuries. In a fashion not totally unlike that of pipe organs, reed organs generate sound by forcing air over a set of reeds by means of a bellows, usually operated by constantly pumping a set of pedals. While reed organs have limited tonal quality, they are small, inexpensive, se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pforzheim
Pforzheim () is a city of over 125,000 inhabitants in the federal state of Baden-Württemberg, in the southwest of Germany. It is known for its jewelry and watch-making industry, and as such has gained the nickname "Goldstadt" ("Golden City"). With an area of , it is situated between the cities of Stuttgart and Karlsruhe at the confluence of three rivers ( Enz, Nagold and Würm). It marks the frontier between Baden and Württemberg, being located on Baden territory. From 1535-65, it was the home to the Margraves of Baden-Pforzheim. The City of Pforzheim does not belong to any administrative district (''Kreis''), although it hosts the administrative offices of the Enz district that surrounds the town. During World War II, Pforzheim was bombed by the Allies a number of times. The largest raid, and one of the most devastating area bombardments of World War II, was carried out by the Royal Air Force (RAF) on the evening of 23 February 1945. Nearly one third of the town's p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germany
Germany, officially the Federal Republic of Germany (FRG),, is a country in Central Europe. It is the most populous member state of the European Union. Germany lies between the Baltic and North Sea to the north and the Alps to the south. Its 16 constituent states have a total population of over 84 million in an area of . It borders Denmark to the north, Poland and Czechia to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr. Settlement in what is now Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submersible
A submersible is a small watercraft designed to operate underwater. The term "submersible" is often used to differentiate from other underwater vessels known as submarines, in that a submarine is a fully self-sufficient craft, capable of independent cruising with its own power supply and air renewal system, whereas a submersible is usually supported by a nearby surface vessel, platform, shore team or sometimes a larger submarine. In common usage by the general public, however, the word "submarine" may be used to describe a craft that is by the technical definition actually a submersible. There are many types of submersibles, including both crewed and uncrewed craft, otherwise known as remotely operated vehicles (ROVs) or unmanned underwater vehicles (UUVs). Submersibles have many uses worldwide, such as oceanography, underwater archaeology, ocean exploration, adventure, equipment maintenance and recovery, and underwater videography.

Speleonaut
''Speleonaut'' (named from the Greek words for "cave" and "sailor") is the submersible used by the cave diver Jochen Hasenmayer. After the 1989 decompression accident that left his legs paralyzed, Hasenmayer designed the ''Speleonaut'' with his friend Konrad Gehringer in order to continue exploring the Blauhöhle cave system, which begins at the base of the Blautopf spring in the Swabian Jura mountain range. The ''Speleonaut'' is wide and has nine engines, making it easy to maneuver in all directions. It is the first submarine designed specifically for the exploration of caves. According to Hasenmayer, the ''Speleonaut'' has been tested in Lake Constance to a depth of and has a design limit of . The ''Speleonaut'' was first used at the Blautopf in 1996. In 2001 Hasenmayer reached the ''Mörikedom'' ("Mörike cathedral") chamber of the Blauhöhle, which he had discovered in 1985, in the ''Speleonaut''. In 2004 he reached a point beyond the ''Mörikedom'' into the mountain. In t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Cave Diving
Cave-diving is underwater diving in water-filled caves. It may be done as an extreme sport, a way of exploring flooded caves for scientific investigation, or for the search for and recovery of divers or, as in the 2018 Thai cave rescue, other cave users. The equipment used varies depending on the circumstances, and ranges from breath hold to surface supplied, but almost all cave-diving is done using scuba equipment, often in specialised configurations with redundancies such as sidemount or backmounted twinset. Recreational cave-diving is generally considered to be a type of technical diving due to the lack of a free surface during large parts of the dive, and often involves planned decompression stops. A distinction is made by recreational diver training agencies between cave-diving and cavern-diving, where cavern diving is deemed to be diving in those parts of a cave where the exit to open water can be seen by natural light. An arbitrary distance limit to the open wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jochen Hasenmayer
Jochen Hasenmayer (born 28 October 1941 in Pforzheim, Germany) is a German speleologist and cave diver from Birkenfeld in Baden-Württemberg, whose spectacular dives have frequently made headlines. Cave diving Hasenmayer began his cave diving career in 1957 at the age of fifteen, exploring the Falkensteiner Höhle near Stuttgart. Beginning in the 1960s, Hasenmayer explored many karst springs and caves in the Swabian Jura and elsewhere in Southern Germany, including the Wimsener Höhle, the Aachtopf and the Blautopf. He became famous in 1985 due to the discovery of the ''Mörikedom'' ("Mörike Cathedral", named after the German pastor and poet Eduard Mörike), the second big air-filled chamber in the Blauhöhle, about into the cave system. Some of his terminuses (farthest point reached in a cave) have not been exceeded. In the late 1970s, Hasenmayer was among the divers who searched for an underwater connection between Kingsdale Master Cave and Keld Head in the Y ...

Blautopf
The Blautopf (German for ''Blue pot'') is a spring that serves as the source of the river Blau in the karst landscape on the Swabian Jura's southern edge. It is located in Blaubeuren, Alb-Donau-Kreis, Baden-Württemberg, Germany (approximately west of Ulm). Description It forms the drain for the Blau cave system; the river Blau after flows into the river Danube in the city of Ulm. Because of its high water pressure, the spring has developed a funnel-like shape with a depth of 21 metres (69 ft). The water's peculiarly blue color, varying in intensity depending on weather and flow, is the result of physical properties of the nanoscale limestone particles densely distributed in the water. They cause Rayleigh scattering of light, preferentially scattering the blue color of the visible light. A similar effect is observed at the Blue Lagoon near Reykjavík, where the color originates from nanoscale silica particles.Lonely Planet Best of Germany (Travel Guide), 2019. Benedict W ...
