Abstract
An adaptive system for harvesting hydrokinetic energy from flowing fluid uses a hydrofoil-type vane in a flow-way and an electrical power generator to convert torque generated by the oscillating vane to electrical current. The generator may be electromagnetic or piezoelectric. The system includes a control module that measures the oscillation of the vane, the generated torque, or the characteristics of the generated current, and modifies the resistance of the vane or the conversion of the electrical current in response to changes therein. Some systems include a frame that can be anchored in a body of water. Some systems are portable and provide illumination. Some systems are adapted for use as hiking or camping gear and may be inserted into stream beds or used as walking sticks. Some systems are in-line devices. Some systems are adapted as fishing lures.
