Design Thinking about Entromorphy
Enteromorpha is a fast reproductive algae. In order to prevent families from suffering from the outbreak of Enteromorpha, I design a series of products. Enteromorpha Harvester can timely and efficiently collect Enteromorpha in small size water area. Household Composter can compost organic wastes with Enteromorpha collected, and produce solid fertilizer and soilless culture nutrient solution. Soilless Culture Module can be freely combined into soilless culture appliance, and apply nutrient solution produced by Family Composter to it. Besides, I introduce the concept of future eco-life. I connect nutrient solution network to family electric grid, so that plants can receive nutrition from sockets and appliance’s ports.
DIRECTLY GO TO
Since mid-June 2008, a large number of Enteromorpha prolifera drifted from the middle of the Yellow Sea to the waters near Qingdao. Qingdao coastal waters and the coast suffered a sudden and rare Enteromorpha prolifera disaster.
In July 2011, a large area of Enteromorpha prolifera entered Qingdao, Yantai, Weihai, Rizhao and other coastal waters of Shandong Province. Some beaches were accumulated a thick Enteromorpha prolifera, which seems like the prairie. The coastal culture and tourism industry were adversely affected.
Affected by ocean currents and wind direction, the largest wave of Enteromorpha prolifera floated to Qingdao from July 2, 2013.
The Cause of Outbreak of Enteromorpha
From 1990 to 2010, the world’s carbon dioxide, methane, nitrogen oxides, fluoride and other greenhouse gas emissions. The histogram shows that gas emissions are increasing in every day.The world’s oceans began to change from 1880 and the surface temperature gradually increased from the 20th century. From 1901 to 2015, it increased by 0.13 ° F per decade. The proliferation of Enteromorpha prolifera is related to the greenhouse temperature. The global warming makes the sea-level temperature rise. It will up to 20℃ in summer, which is suitable for the proliferation of Enteromorpha prolifera.
The Existing Collection of Enteromorpha
The existing Enteromorpha prolifera collectors mainly refer to the large-scale civil harvesters that purchased by the government. The working process is: firstly, pulling Enteromorpha prolifera to the conveyor belt. Then, delivering them to the rowing mouth and they are crossly laid on the floor of the storage.
The advantage of this large-scale harvester is that it can operate in large areas. It is able to effectively response to a sudden outbreak of Enteromorpha prolifera.
The disadvantage is that it is easy to be stranded near the seashore. Besides, this large-scale machine is unnecessary when dealing with a small-scale outbreak of Enteromorpha prolifera, because it may cause energy waste.
