Solar Evaporation Ponds in the Atacama Desert. The largest operating solar pond for electricity generation was the Beit HaArava pond built in Israel and operated up until 1988. It had an area of 210,000 m² and gave an electrical output of 5 MW. [3] India was the first Asian country to have established a solar pond in Bhuj, in Gujarat.
A float weighs about 10 kg. The lower end is sealed with a flat aluminium endplate where all electrical and mechanical penetrators are located. The glass thickness is about 5 mm, giving the float a theoretical maximum depth of about 2700 m. The external ballast is suspended by a short piece of wire chosen for its resistance to saltwater corrosion.
The Lindholme Gear is five cylinder-shaped containers joined together by lengths of floating rope. [1] The centre container would house a nine-man inflatable dinghy with the other containers housing survival equipment such as emergency rations and clothing. [1] The containers were discarded containers from the tail-units of 500lb and 250lb ...
Electrical equipment may be designed with a floating ground for one of several reasons. One is safety. For example, a low-voltage DC power supply, such as a mobile phone charger, is connected to the mains through a transformer of one type or another, and there is no direct electrical connection between the current return path on the low-voltage side and physical ground (earth).
The first floating solar installation was in Aichi, Japan, in 2007, built by the National Institute of Advanced Industrial Science and Technology. [9] [19] In May 2008, the Far Niente Winery in Oakville, California, installed 994 solar PV modules with a total capacity of 175 kW onto 130 pontoons and floating them on the winery's irrigation pond.
Facultative lagoon (polishing pond) providing tertiary treatment after a constructed wetland in Hamburg-Allermöhe, Germany. Overflow from the facultative lagoon may be routed through one or more polishing ponds supporting lower populations of anaerobic micro-organisms and a higher proportion of aerobic organisms adapted to survival in lower concentrations of organic material.
In the Drownproofing survival technique, the subject floats in a relaxed, near-vertical posture, with the top of the head just above the surface. Using the arms or legs to exert a downward pressure, the subject raises himself sufficiently so that the mouth is above the surface and a breath is taken, before dropping back into the relaxed float.
R/P FLIP (floating instrument platform) is an open ocean research platform [3] [6] that was owned by the U.S. Office of Naval Research (ONR) and operated by the Scripps Institution of Oceanography. [7]
