Conceptual design of a next-generation wind turbine

Project Member(s): Ji, J.

Funding or Partner Organisation: M Investment Ltd (M Investment)

Start year: 2016

Summary: Ambitious worldwide renewable energy targets are pushing wind energy to become one of mainstream power sources. The strong growth of the wind technology market, underpinned by policy goals around the world, has led to the rapid development of higher and larger capacity wind turbines. As the weight and height of turbines increase, the materials costs of wider, stronger support towers, as well as the cost of maintaining components housed so far from the ground, are cutting into the efficiency benefits of larger turbines. This project aims to develop a different type of wind turbine: a bladeless wind turbine by converting the vibrating kinetic energy into electricity through a linear generator. The anticipated outcomes will provide a conceptual design of a new wind turbine with high conversion efficiency in a wide range of oscillating frequencies, and significant reduction in noise generated. The designed wind turbine is expected to have an optimised energy production with significant reductions in manufacturing and maintenance costs.
