PRECEDENT STUDY: RAINBOW CLOUD Artist Team: Chie Fuyuki, Lichao Qin Artist Location: Beijing, China 2012 Land Art Generator Initiative (LAGI) competition entry. This design mainly uses solar technique to generate energy and brings lights in the nightv. It also provids the visitors a unique opportunity to become aware of the ecological system of the park. The aim of the design is going to transform the site (Fresh Kills) into a splendid ecosystem. This design is not only a restoration process of the park but also provide visitors an opportunity to aware the ecological system of the park.
What theory was engaged? What designs are inspired by these projects? What change do they cause in the world? Pattern deisgn is quite interesing and beautiful The design was inspired by the cloud just like the name of the project. Since cloud is dynamic and ubiquitous mass of particles, designers follow the structure of the clouds and its movements to create the clouds pattern on the site. The key idea of this design is the 'rainbow cloud'. The clouds are no longer being white, instead these clouds are colourful. The collocation of the balloons refers to 'clouds' characteristic, which are flexibility, impermanency, aesthetic and informative.
What did they contribute to the field of ideas, technical workflows, patterns of living and ways of thinking? Portable and fixed balloons are energy collectors colorful lighting pattern shows how much energy generated by the whole park Different 'cloud' colour represents different energy they receivedElectric device can receive the information about the balloons (energy collector)
How much energy does project produce? This design will generate 52,962 kw of electric energy which can supply power to approximately 7,614 houses in the city
ENERGY STUDY: HYDROELECTRIC Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy, accounting for 16 percent of global electricity generation 3,427 terawatt-hours of electricity production in 2010, and is expected to increase about 3.1% each year for the next 25 years.
Conventional (dams) Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. Pumped-storage This method produces electricity to supply high peak demands by moving water between reservoirs at different elevations. Run-of-the-river Run-of-the-river hydroelectric stations are those with small or no reservoir capacity, so that the water coming from upstream must be used for generation at that moment, or must be allowed to bypass the dam. Underground An underground power station makes use of a large natural height difference between two waterways, such as a waterfall or mountain lake.
COMPARE TO OTHER RENEWABLE ENERGY Advantage: flexibility low power costs suitability for insudtrial applications reduce co2 emissions other uses of the reservoir(irrigation)
DIisadvantage: ecosystem demage loss of land siltation anf flow shortage methane emissions relocations failure risks
