China is close to a breakthrough with its first 1 MW airborne wind turbine.

China is close to a breakthrough with its first 1 MW airborne wind turbine, revealed on August 25th by SAWES CTO, Mr. Wang Xinkai.

 

This technology is like a "light gas balloon carrying a power generator flying in the air." Back in October 2024, SAWES successfully tested a smaller S500 model (75m long, 15m wide) in Jingmen, Hubei province. It flew up to 500m and generated over 50 kW, proving its feasibility on a small scale.

The upcoming S1500 system will have over 30 times the power of similar foreign models, making a 1957 idea by scientist Qian Xuesen a reality. China is not only focusing on offshore turbines but also pushing ahead with this airborne technology.

Developed by SAWES in collaboration with Tsinghua University and the Chinese Academy of Sciences' Aerospace Institute, this innovation places turbines in the upper atmosphere where winds are stronger and more stable. This maximizes energy capture, making it ideal for remote areas or disaster zones where traditional power grids are challenging to access.

Other countries also use similar technologies. Hywind Scotland (30 MW, since 2017) and Hywind Tampen (88 MW, since 2023) in Norway are commercial floating wind farms. Portugal has WindFloat Atlantic (25 MW) and the UK has Kincardine (nearly 50 MW), both using semi-submersible structures.

Globally, operational floating wind capacity is around 245 MW, with a potential 266 GW in the pipeline. China is also working on Ocean X (or "Flying V"), a V-shaped floating turbine designed to withstand Category 5 typhoons, weighing 16,500 tons and producing 54,000 MWh annually, enough for 30,000 households.

The unique aspect of China's airborne turbine is its operation in the high atmosphere, independent of water. This differs from traditional floating methods, reducing underwater structural needs and improving deployment in complex terrains or emergency situations. However, controlling the balloon-borne turbine and transmitting power via cables remains a significant technical challenge, along with air safety and transmission stability.

While floating turbines like Hywind and WindFloat offer large-scale power and commercial viability, they have limitations in location and high deployment costs, especially in deep or turbulent waters. If airborne technology overcomes its hurdles, it could mark a new era in wind energy.

Excel Programming with VBA Starter

I am happy that I took the time to become acquainted with this book. The text is well thought out which makes the book interesting and easy to read.

This is an excellent way for people to approach Visual Basic for Applications (VBA) within the Context of Microsoft Excel.

All the key points are demonstrated with code examples. These examples are set for Excel 2010.
Great for beginners but if you're looking to learn find something with more substance & pages than this. As purely an exercise to introduce the topic it gets the job done.

A Brieft of Sap Net Weaver gateway by Christ Wealey.

 

It seems that whichever way you turn now, there’s some new computing device on the market demanding your undivided attention because it’s lighter, faster and generally cooler than any of its rivals or predecessors. However, no matter what features the latest and greatest gadgets have, they all have one thing in common—an insatiable hunger for data!

 

Meeting this seemingly never-ending demand for business data can turn into a major headache for application developers if the API into each business system requires the use of proprietary protocols.
What would make life much simpler is an easy–to–use, well defined API that gives access to the rich wealth of business data and functionality in your SAP systems.
