Abstract

An energy harvesting device is disclosed. The energy harvesting device comprises a duct with an inlet opening and an outlet opening. The energy harvesting device further comprises one or more foils located within the duct wherein a leading edge of the one or more foils are orientated towards the inlet opening. The energy harvesting device also comprises a generator to convert movement of the one or more foils into electricity. The generator comprises one or more vibrational members and an energy conversion means. The one or more vibrational members are configured to exhibit both pivoting motion and the one or more foils are configured to exhibit a rotation motion. The foils may be aerofoils or hydrofoils. The energy harvesting device provides an alternative device for generating renewable energy with numerous advantages. The device harvests vibrational energy, can be optimised to operate over a broad range of fluid flow parameters, has minimal negative environmental impact and is suitable for numerous locations and applications.
