Energy Harvesting

This note initiates a study of a micro-hydropower unit for generating and storing electricity, by harvesting the kinetic energy inherent in the flow or tidal changes of the river.

By virtue of its discrete scale and form, these units can be easily and strategically located in groups in the river, without deleteriously affecting its natural flow or prohibiting navigation around them.

The units feature a solar light beacon at the top of pole-mounted (covered) battery receptacles.

This main structural pole fits into a powered base sleeve, centred within a floating skirt.

The base sleeve is powered by two tri-blade (vertical axis) Darrieus hydrokinetic turbines, which are  activated by the flow of the water and whose orientation relative to that flow is adjusted for maximum harvesting by a fixed rudder-like fin mounted on their single rigid hanging armature.

The batteries can be taken from their receptacles off the main pole for use as required, in anticipation of a targeted generation per unit of approximately 2KWH/day from a water flow rate of 10km/hr.

This project is part of a Fellowship supported by Tilting Axis and Het Nieuwe Instituut, in collaboration with the Amsterdam Museum, De Appel, The Black Archives and Melly.

*korjaal (pronounced kȯr-ē-al) is a dug-out or canoe.
