Storm surge or tidal surge is an offshore rise of water associated with a low pressure weather system, typically a tropical cyclone. Storm surge is caused primarily by high winds pushing on the ocean’s surface. The wind causes the water to pile up higher than the ordinary sea level. Low pressure at the center of a weather system also has a small secondary effect, as can the bathymetry of the body of water. It is this combined effect of low pressure and persistent wind over a shallow water body which is the most common cause of storm surge flooding problems. The term “storm surge” in casual (non-scientific) use is storm tide; that is, it refers to the rise of water associated with the storm, plus tide, wave run-up, and freshwater flooding. When referencing storm surge height, it is important to clarify the usage, as well as the reference point. National Hurricane Center tropical cyclone reports reference storm surge as water height above predicted astronomical tide level, and storm tide as water height above NGVD-29.

Hand
painted porcelains from Buran Benjarong are based on traditional Thai
style paintings. Religious Buddhist beliefs and traditions have been
deeply rooted in everyday life. The Buran Benjarong handmade porcelains
use intricate designs on gorgeous porcelain bowls vases, etc. The
production of the basic porcelain wares are by itself a very tedious
and time consuming process. The hand painting done on these porcelain
wares is a really slow process.

Low-impact lifestyler extraordinaire, John Hermans, devised and built a water wheel for Earth Garden’s writer and forest campaigner, Jill Redwood. Jill can now refill her water tank from the Brodribb River near her farmhouse in Victoria’s East Gippsland. Her water wheel is silent, pumps about a litre a minute, goes 24 hours a day, has only one small moving part, and works on an ancient principle. Here John describes how to build one.

an old water heater tank can be adapted to make a safe and inexpensive biodiesel homebrewing apparatus. An HDPE carboy (white jug in photo) or other tank can become a passive small-scale methanol-catalyst mixer, and an inexpensive centrifugal pump (blue motor in photo) from Harbor Freight tools mixes the two liquids to enable the biodiesel reaction to take place. After a day of settling, the glycerol byproduct can be drained out fairly well- the tanks have a wine-bottle-bottom profile, with a drain at the ‘pointed’ edge, so separation of two liquids can be reasonably clean. The processor costs about $150 in plumbing and electrical, and about a day or less of work. The tank can be an ancient lime-crusted one scavenged from a dump, or can be bought new for about $200 more.

Mit dieser Bauform des Rotors ergibt sich zyklisch ein vollsta”ndiger Verschlu? der Du”seno”ffnung, welcher eine harte Resonanz im Du”senstock zu Folge hat. Der Resonator / Du”senstock sollte hier mit einer hinreichend dicken Wandung definiert werden.

Welcome to the home page of The Tesla Wardenclyffe Project.Our mission is the preservation and adaptive reuse of Wardenclyffe,the century-old laboratory of electrical pioneer Nikola Teslalocated in Shoreham, Long Island, New York. Also..The Peerless Photo Products site presently includes a 94′ x 94′ brick building designed by noted turn-of-the-century architect Stanford White, the perimeter foundation wall of the communications facility’s wireless transmission tower, and a number of newer structures.

One of the more controversial topics involving Nikola Tesla is what became of many of his technical and scientific papers after he died in 1943. Just before his death at the height of World War II, he claimed that he had perfected his so-called “death beam.” So it was natural that the FBI and other U.S. Government agencies would be interested in any scientific ideas involving weaponry. Some were concerned that Tesla’s papers might fall into the hands of the Axis powers or the Soviets.
