    Swiss designers have launched solar yachts, which can travel around the world without oil Swiss designers have launched a solar yacht full of a sense of future, equipped with enough solar panels, and the size is close to the tennis court The ship can hold 10 people and is equipped with an artificial intelligence system that can be driven by one person The ship's 800 kilowatt battery can provide about 10 hours of cruise capability and can be extended by solar cells When conditions permit, solar cells can be used as the only power of the ship Https://www.dailymail.co.uk/sciencetech/article-6180957/solar-powered-yacht-cruise-entire-globe-without-stopping-refuel-unveiled.html Chinese and Japanese scientists jointly develop and prepare new technology of liquid fuel The team has made innovative achievements in the research of Fischer Tropsch synthesis catalyst, providing a simple and effective method for the direct synthesis of different types of liquid fuels The results were recently published in nature catalysis "This method is expected to develop into a new generation of coal to oil catalyst technology." Wang Ye said that from the perspective of basic research, further design of catalysts is needed in the future to improve the selectivity of specific products and make the product distribution more concentrated, especially to reduce the selectivity of low-carbon alkanes including methane In addition, the long-term stability of bifunctional catalysts needs further verification "The laboratory technology of bifunctional catalyst has been basically mature, and it still needs pilot test and corresponding engineering and technical problems to be solved before industrialization." Https://www.nature.com/articles/s41929-018-0144-z the first carbon fiber composite metro vehicle appeared in Berlin on the 18th of the world's first light weight metro vehicle with all carbon fiber structure at the international rail transit technology exhibition in Berlin This achievement is independently developed by CRRC Sifang Co., Ltd and China Germany rail transit technology (Dresden) joint R & D Center (CG rail) It is a major technological breakthrough in the "next generation subway" project of CRRC, and also fully demonstrates the strong strength of China Germany cooperation in the field of lightweight The cab and equipment cabin with 90% carbon fiber composite material utilization rate also set a new benchmark for lightweight field Compared with the traditional metal materials, the weight of the equipment cabin is reduced by 30%, and the "slimming" of the cab is more than 30% In addition, engineers have overcome many technical problems For example, through integrated optimization, the number and type of parts are reduced on the premise of ensuring complete functions At present, CG rail has applied for 16 patents Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2018-09/20/content_.htm? Div = - 1 Marine plastic pollution is threatening the survival of turtles, according to a new study released in Australia Researchers from the Australian federal organization for scientific and industrial research dissected 1000 dead turtles washed onto Australian beaches and quantified the relationship between turtle death and plastic ingestion The results showed that once the turtle swallowed 14 pieces of plastic, the risk of death could reach 50% That doesn't mean turtles will not die if they swallow less than 14 pieces of plastic, the researchers said In the study, some of the dead turtles swallowed only one piece of plastic, one of which died of intestinal puncture by hard plastic, the other died of intestinal obstruction caused by swallowing soft plastic Https://www.nature.com/articles/s41598-018-30038-z Volvo will use 25% recycled plastic in cars from 2025 Volvo has committed to use 25% recycled plastic in cars from 2025 It has launched a specially built XC60 T8 plug-in hybrid SUV, which looks exactly the same as existing models, but its plastic parts have been replaced with recycled materials The interior material of the car is made of renewable fiber and plastic from abandoned fishing nets and sea ropes, while the carpet is made of recycled cotton mixture of fiber made from plastic bottles and waste leftovers It also calls for suppliers in the automotive industry to work more closely with automakers to develop next-generation components that are "as sustainable as possible." Martina buchhauser, senior vice president of global sourcing at Volvo cars, said: "in terms of sustainable development, we have cooperated with some excellent and forward-looking suppliers But if we want to achieve our ambition, we really need to increase the availability of recycled plastics That's why we call on more suppliers and new partners to join our investment in recycled plastics and help us realize our ambitions " https://www.energylivenews.com/2018/06/19/volvo-to-use-25-recycled-plastics-in-cars-from-2025/
