Can Nam Ngum solar replace Mekong hydro in Laos?

~ Đào Thu Hằng ~ Bình luận về bài viết này

The Lancang-Mekong River is being decimated by hundreds of tributary and mainstream hydroelectric projects from the Tibetan Plateau in China to Lower Sesan in Cambodia. On the Mekong, the Laos Government has constructed the majority of these projects and it is planning even more. But why does it only focus on hydroelectric power plants (HPP’s)? What about other renewable energy sources? Can Nam Ngum solar replace Mekong hydro?

Dòng sông Lan Thương–Mekong đang bị tàn phá bởi hàng trăm dự án thủy điện trên dòng chính và các phụ lưu của nó từ cao nguyên Tây Tạng ở Trung Quốc tới hạ lưu sông Sê san ở Campuchia. Riêng trên dòng chính Mekong, Chính phủ Lào đóng vai trò chính trong việc xây dựng những dự án này và thậm chí đang có kế hoạch xây thêm. Nhưng tại sao nước này lại chỉ tập trung vào các nhà máy thủy điện (hydroelectric power plants – HPPs)? Còn những nguồn năng lượng tái tạo khác thì sao? Liệu điện mặt trời Nam Ngum có thể thay thế thủy điện trên dòng Mekong ở đất nước này?

Tôi đã thực hiện một nghiên cứu khả thi đơn giản về kinh tế – kỹ thuật để trả lời câu hỏi quan trọng ở trên, và kết quả là có, hoàn toàn có thể. Một trang trại điện mặt trời nổi (floating solar-with-storage, FSS) với công suất thiết kế 11.400 MW là hoàn toàn khả thi về mặt kỹ thuật để sản xuất ra một lượng điện tương đương 15.000 GWh/năm và chi phí thấp hơn so với cả 3 dự án thủy điện hiện đang được lên kế hoạch xây dựng tại Lào – gồm Pak Lay, Pak Beng và Luang Prabang. Quy mô dự án FSS Nam Ngum là rất lớn nhưng có thể thực hiện trong 15 năm với công suất 760 MW/năm với sản lượng 1.000 GWh/năm.

Bắt đầu dạy tiếng Anh cho trẻ em ở nhà như thế nào?

~ Đào Thu Hằng ~ 2 bình luận

English: How do I start teaching my kids English at home?

Nhiều phụ huynh muốn tự dạy tiếng Anh cho con mình ở nhà nhưng lại không biết bắt đầu từ đâu. Không sao cả nếu Tiếng Anh của chính bạn không tốt lắm. Điều quan trọng nhất là bạn nhiệt tình và cho con bạn nhiều khích lệ và lời khen. Con bạn sẽ đón nhận sự nhiệt tình của bạn đối khi học ngôn ngữ. Đừng lo lắng nếu bé chưa nói được tiếng Anh ngay lập tức. Các bé cần thời gian nhất định để tiếp thu ngôn ngữ mới. Hãy kiên nhẫn và các con sẽ bắt đầu nói tiếng Anh theo thời gian của các em.

Tạo thói quen

Hãy tạo thói quen sử dụng tiếng anh tại nhà. Hãy sử dụng những hội thoại ngắn, lặp lại nhiều lần hơn là dùng những đoạn dài và không thường lặp lại. Chỉ 15 phút tương tác với trẻ ở tuổi rất bé là đủ. Khi bé lớn hơn và khả năng tập trung tăng lên, bạn có thể dần dần dung những hội thoại dài hơn. Những hoạt động ngắn và đa dạng sẽ giúp con tập trung chú ý vào bài học.

Buying first home remains a pipe dream for young Vietnamese

Surging prices and a decline in the supply of affordable apartments are making it almost impossible for young Vietnamese to buy their first home.

Pham Hoai Nam used to think that being a grown-up means having a stable job, a good salary, a beautiful girlfriend, and his own house.

Now, at age 28, he is able to check off all of those items except the last one.

“My girlfriend and I plan to get married next year, and our only major concern now is finding a place to live,” Nam, who works as an electronics salesman in Hanoi, says.

He is among many young Vietnamese in major cities who are finding that their dream of owning a home is becoming increasingly elusive as real estate prices rise faster than incomes amid a decline in affordable apartment supply.

The failure of China’s largest corporations to meet waste management and emissions reductions targets have given them the lowest score in a ranking of how companies report their environmental impact. Singapore companies also fare poorly while Hong Kong firms top the list.

If John Carlisle had a cat flap, scientific fraudsters might rest easier at night. Carlisle routinely rises at 4.30 a.m. to let out Wizard, the family pet. Then, unable to sleep, he reaches for his laptop and starts typing up data from published papers on clinical trials. Before his wife’s alarm clock sounds 90 minutes later, he has usually managed to fill a spreadsheet with the ages, weights and heights of hundreds of people — some of whom, he suspects, never actually existed.

Hanoi’s first metro line, the Cat Linh-Ha Dong route, has begun a 20-day commercial operation run for inspection purposes.

The trial will check all aspects or the line’s operations, from functioning stations with staff on duty at operation rooms and ticket booths. Electronic signs and loudspeakers are turned on to instruct metro commuters. Six to nine trains will operate on the route.

The first metro line runs 13 kilometers from Cat Linh Station in downtown Dong Da District to the Yen Nghia Station in the southwestern Ha Dong District.

The metro had made its first trial run in September last year, but that test was supervised by Chinese experts from the Shenzhen Metro Company.

The ongoing commercial trial will be supervised by Vietnamese employees from state-owned Hanoi Metro Company Limited.

The 20-day period will verify system safety and operational capacity of all employees, which is a mandatory step in the inspection process, said a representative from the Chinese general contractor.

It has been reported several times that work on the line is 99 percent complete. The 1 percent remaining work is mainly outlook finishing.

Hanoi, 24 October 2019 – The Mekong Delta is one of the most vulnerable deltas to climate change, particularly sea level rise. However, the social and economic developments in the region also have a significant impact on the land. Urbanisation, land-use transformation, intensification of economic activities and human protection against natural disasters has led to the large-scale extraction of fresh groundwater, heavy loading of infrastructure, upstream dykes and dam construction as well as loss of habitat and biodiversity. These human activities have accelerated the sediment starvation, salinisation, land subsidence and erosion. The Rise and Fall research program, a cornerstone in the Vietnam – the Netherlands delta collaboration, addresses these challenges with the Dutch multi-disciplinary approach in delta management by following four lines of research: fresh groundwater reserves, saline intrusion to surface water, land subsidence and governance. This research program plays an important role in the development of strategies and policies for the sustainable development of Mekong Delta with the significant findings as follow.

Mekong delta is much lower than previously assumed

Wind energy could cover more than one third of global power needs in 2050 reducing global carbon emissions by a quarter, new IRENA report finds

IRENA_Future of Wind_press release.jpg

Beijing, China, 21 October 2019 – Asia could grow its share of installed capacity for onshore wind from 230 Gigawatt (GW) in 2018 to over 2600 GW by 2050, a new report by the International Renewable Energy Agency (IRENA) finds. By that time, the region would become a global leader in wind, accounting for more than 50 per cent of all onshore and over 60 per cent of all offshore wind capacity installed globally.

Distraught Vietnamese families were seeking information about their missing loved ones last night amid growing fears that some of the 39 people who died in a refrigerated truck in Essex were from the country.

Pham Thi Tra My, 26, sent a text message to her mother saying she could not breathe at about the time the truck was en route from Belgium to

Britain

, Hoa Nghiem from Human Rights Space, a civic network based in Vietnam, said.

“It was told on the news that

all 39 people were Chinese

but Tra My’s family is trying to verify if their daughter was among them as the last dying text from her was coincidentally in time,” she wrote on Twitter.

“Our contact is getting more alerts that there could be more Vietnamese people in the truck.”

The animated movie Abominable will skip Malaysian theaters after producers decided against cutting out a scene showing a map supporting Chinese claims to the disputed South China Sea.
Vietnam already pulled the U.S.-Chinese production from theaters over a fleeting image of the so-called nine-dash line, a vague and broken outline depicting much of the resource-rich sea as Chinese territory. China’s claims to the sea overlap with claims by Vietnam, Malaysia and other Asian governments.

Last week, the Nobel Prize in chemistry was awarded to John Goodenough, Stanley Whittingham and Akira Yoshino for their work developing the lithium-ion battery. The Royal Swedish Academy of Sciences, in announcing the award, said the three men “created a rechargeable world.” The ubiquitous battery is now found in items as varied as hearing aids and power grids. It is a testament not just to technological revolutions, but also to the power of advancements in performance and decreases in cost. Tiếp tục đọc “Bullard: How a battery can lead a quiet revolution” →
