Product or process

bioSTREAM™ is a tidal power system that mimics thunniform swimming fish such as tuna, sharks, and mackerel. However, instead of moving through water as they do, sweeping their caudal fins back and forth, bioSTREAM™ is anchored to the bottom. There, it can rotate with the incoming or outgoing tide, and the energy in the passing flow is used to drive the device motion against the resisting torque of an electric generator. In the event of extreme flows, the device can assume a streamlined configuration to avoid damage.
