Sydney Park Water Reuse Project is part of City of Sydney’s Decentralized Water Master Plan (2012-2030) . It designed by   Turf Design Studio & Environmental Partnership . The aim of this project is that alleviating 10% water demand of the city. Sydney Park was once industrial land and landfill. In the past two decades, people have made many efforts to transform it into a park of 44 hectares, which is extremely important value for the development of communities in south-eastern Sydney.   There are three key points in the project. First and foremost, water resources management is necessary to efficiently recover urban wastewater, improve water quality and reduce consumption of drinking water. The second point is to create places suitable for people's activities so that everyone who comes to the park can enjoy it. For this reason, the park needs a comfortable environment to provide people with a place to live, study or simply stay. In order to create a comfortable and ...

World Trade Centre Bahrain has an amazing design which is the wind turbines. The generator windmill has a rotor speed of 38 revolutions per minute at full load and is powered by a series of gearboxes placed in the engine compartment to run the generator at 1,500 revolutions per minute. The optimal power generation design is approximately 225 kW at a wind speed of 15-20 m/s. Moreover, the fan rotor has a diameter of 29 meters and is made of 50 layers of glass fibre. When the wind is strong or needs to be transferred to a standstill state, the top of the fins will be pushed outwards, increasing the total torque of the rotor and achieving the purpose of deceleration. To protect the building from the natural disasters. The maximum wind speed that the wind turbine can withstand is 80 meters per second, which means it can withstand Class 4 hurricanes.   There are some really difficult challenges when this building is building. The first challenge is the design of wind turbine impel...

Following the electric car and energy company, Tesla sold the Model S electric car, the electric vehicle becomes a hot topic for the general public. It is necessary to consider the future development of the electric vehicle, whether it is really environmentally friendly.   Today, I only talk about the electric car, no other type of vehicles. There are two types of the electric car, one is the fuel cell cars and the other is pure electric cars. First and foremost, the fuel cell cars have more energy conversion links, and the pure electric cars dominate energy conversion efficiency. A pure electric car needs 20 mins even if it is fast-charged, and the hydrogen-fuel car will be hydrogenated for 5 mins, and the fuel cell vehicle dominates from the energy supply rate. However, the fuel cell cars are faced with difficulties in hydrogen production, transportation, storage, and manufacturing of low-cost fuel cells. At present, Japanese engineers and other companies are making great ef...

Sloping roof refers to roofs with a drainage slope of more than 3%. Sloping roofs are widely used in buildings. They mainly include single-slope, double-slope, four-slope and fold-back these four types. This roof has many benefits and potential benefits for the outdoor and indoor environment. First and foremost, the sloping roof will provide a more comfortable indoor environment with some passive designs. Because of the slope, it has a larger area of the face, it means that it will provide more natural light if you need a natural light roof. Furthermore, to avoid the much radiation transfers to the indoor, under the sloping roof, a compartment can be installed to isolate the heat or keep warm. Moreover, this compartment also can be a room for building equipment, such as air conditioning external machine and rainwater storage box. However, before installing equipment in the compartment, the strength of the roof structure should be evaluated. In addition, sloping roofs also ...

The South-to-North Water Diversion Project is a strategic project of the People's Republic of China and is divided into three routes: East, Central, and West. The starting point of the Eastern Route Project is located at the Jiangdu Water Control Project in Yangzhou, Jiangsu Province; the middle line project is located at the Danjiangkou Reservoir in the upper and middle Hanjiang River. The water supply areas are Henan, Hebei, and Beijing. Four provinces (cities) in Tianjin.   The idea of the project plan began in 1952 when Chairman Mao visited the Yellow River. Since then, after analyzing and comparing more than 50 programs, the water transfer program has obtained a large number of valuable results. The South-to-North Water Diversion Project planning area involves a population of 438 million people and a water transfer scale of 44.8 billion cubic meters. The total length of the east, middle and west lines of the project planning are 4350 kilometers. The total length of the main l...

Bahrain, an island country near the west coast of the Persian Gulf, has a tropical desert climate. World Trade Centre Bahrain, costing 35 million BP (more than 90 million U.S. dollars), is the first skyscraper in the world to use wind energy as a source of electricity. The building consists of two traditional Arabic “wind towers” high-rise buildings, such as a comparative winged sea sail. The hurricane unfolds, strong and powerful, located in the blue shore of the Arabian Gulf. World Trade Centre Bahrain is a 240-meter-high, twin-tower structure building., whose main body is oval in shape. Three horizontally supported wind turbines with a diameter of 29 meters are installed between the two buildings. The sail-like building forms the convection of the sea breeze before the two buildings, which accelerates the wind speed. In addition, the wind turbines are expected to support 11%-15% of the electricity needed for the building. The installation cost of these three wind turbines i...
