Low power wind generator

According to the last report from the International Energy Agency, global demand for electricity is set to increase further as a result of rising household incomes, with the electrification of transport and heat, and growing demand for digital connected devices and air conditioning. This growing demand and the raising concern about the environmental and health impacts, inspired us to investigate and develop next generation technologies aimed to be increasingly efficient and at the same time, to have less impact on the environment. In addition, IAE report states that rising electricity demand was one of the key reasons why global CO2 emissions from the power sector reached a record high in 2018, yet the commercial availability of a diverse suite of low emissions generation technologies also puts electricity at the vanguard of efforts to combat climate change and pollution. Decarbonized electricity, in addition, could provide a platform for reducing CO2 emissions in other sectors through electricity-based fuels such as hydrogen or synthetic liquid fuels. Renewable energy also has a major role to play in providing access to electricity for all. IEA, Electricity generation by fuel and scenario, 2018-2040, IEA, Paris https://www.iea.org/data-and-statistics/charts/electricity-generation-by-fuel-and-scenario-2018-2040 As depicted, this has led into a paradigm shift in terms of electrical energy generation and distribution, encouraging the early adoption of solar, wind and tidal energy, among others, to address the growing global demand. The report forecasts that solar and wind energy are expected to quadruplicate in the coming 20 years. This panorama encouraged our team to investigate wind powered electrical generation and aimed us to develop a Wind Power Generation System for domestic and industrial use. After a small survey we identified the main drivers for the project brief: it must not disturb the visual nor be noisy, it should be accessible and be easy to install and maintain, it also should be capable to inject energy into the public network. Therefore we decided a to start our study by adopting a modular design, based on a 300W permanent magnet motor, that could be interconnected to generate 900 W average, trough 3 modules combined. Another important point pursued by our team is the use of recycled and recovered materials, which are commercially available thus the culture of separation and recycling is not yet firmly rooted in our society. We discovered opportunities in polymers developed for the mass consumption industry, that helped with the blades construction. By using different digital techniques different proposals for blade designs and support structures were analyzed, always keeping the focus on the main working guidelines: Low cost Easy installation, low maintenance Efficient blade design Lightweight structure Easy to replicate / integrate recycled materials
