Located in Stockholm, Sweden, the Söder Torn high-rise residential building was completed back in 1997. Recently, a local architectural firm named Belatchew Arkitekter has proposed an unusual yet intriguing plan: to transform this aging structure into a zero-energy building that actually produces more energy than it consumes. The concept might sound appealing at first, but the execution is a bit strange. The proposal involves attaching long, straw-like structures to the building's exterior, designed to capture wind and convert it into electricity. From the visual renderings, the building looks as if it’s covered in cilia or lashes, giving it a rather surreal appearance. But is this design truly functional? The answer is yes—according to the architects, the added elements are made from a lead-free ceramic composite material that can generate electricity through kinetic movement. This process, known as the piezoelectric effect, allows the structures to produce power even in light winds. Unlike traditional wind turbines, these extensions are safer for wildlife and operate silently, making them a more environmentally friendly option. Beyond energy production, the project also aims to enhance the building’s functionality. The top of the structure will be turned into a new public observation deck, offering breathtaking panoramic views of Stockholm. This innovative upgrade could turn Söder Torn into not just a residential tower, but a landmark that serves both as a home and a renewable energy generator. If the community embraces this bold transformation, Söder Torn could become one of the most unique examples of sustainable architecture in the world—proving that even old buildings can be reimagined for a greener future.
The high chromium wear-resistant alloy steel balls produced by our company have the following advantages:
1. With extremely high hardness, usually between 60-66 HRC, it can effectively resist wear and grinding and extend service life.
2. Excellent wear resistance, able to maintain stable performance during high-speed grinding and grinding, reducing the risk of wear and fracture.
3. It has good impact resistance and can withstand greater impact force and is not easy to break during high-speed grinding and grinding.
4. It has good corrosion resistance, can maintain stable performance in wet and corrosive environment, and is not easy to rust and corrosion.
5. Can maintain stable performance in high temperature environment, not easy to deform and soften, suitable for high temperature grinding and grinding process.
6. The wear rate of the steel ball is low, which can reduce the loss of abrasives and materials and improve the grinding and grinding efficiency.
