Background to the invention of bladeless wind turbines

The history of the invention of bladeless wind turbines dates back to the early 1980s. At that time, traditional bladed wind turbines had some problems, such as high noise, bulky shape and high maintenance costs. . Therefore, some scientists started trying to develop a new type of wind turbine to solve these problems. The design concept of bladeless wind turbines is derived from the principle of pterosaur flight, which involves generating lift using aerodynamic effects. Bladeless wind turbines use a pterosaur-like design that uses a cylindrical rotor instead of traditional blades. Under the influence of wind, the rotor rotates and generates kinetic energy, which in turn causes the generator to produce electricity. Compared with traditional blade wind turbines, bladeless wind turbines have the following advantages: low noise, beautiful appearance, lowmaintenance costs and little impact on the environment such as birds. Therefore, bladeless wind turbines are considered a new, smarter, more efficient and more environmentally friendly wind power generation technology. Bladeless wind turbines have become a research hot spot in the field of wind power generation technology and have begun to be used in some places. However, the technology is still in its early stages of development and requires further research and refinements to improve its efficiency and stability.

Biogas is a combustible gas produced by microbial fermentation of organic materials such as human and animal manure and crop straw, isolated from air (reducing conditions) and under conditions of temperature and d appropriate humidity. The main component of biogas is methane, which accounts for approximately60 to 80% of the different gases produced. Methane is an ideal gaseous fuel. It is colorless and odorless and burns when mixed with an appropriate amount of air. The calorific value of pure methane is 34,000 joules per cubic meter and the calorific value of biogas is approximately 20,800 to 23,600 joules per cubic meter. In other words, after complete combustion of 1 cubic meter of biogas, it can produce heat equivalent to that provided by 0.7 kilograms of anthracite. The use of this combustible gas to produce electricity is biogas electricity production.

Wind power generation involves using wind energy to push the blades to rotate and drive the generator to produce electricity. This “rotating blade” mechanism is called a “wind turbine”.
