A Tidal Power conversion system - bioSTREAM...

New power generating systems: bioPOWER AND bioSTREAM systems.

The tidal power conversion system, bioSTREAMâ„¢, is based on the highly efficient propulsion of Thunniform mode swimming species, such as shark, tuna, and mackerel.

The bioSTREAMâ„¢ mimics the shape and motion characteristics of these species but is a fixed device in a moving stream. In this configuration the propulsion mechanism is reversed and the energy in the passing flow is used to drive the device motion against the resisting torque of an electrical generator.

Due to the single point of rotation, this device can align with the flow in any direction, and can assume a streamlined configuration to avoid excess loading in extreme conditions. Systems are being developed for 250kW, 500kW, and 1000kW capacities to match conditions in various locations.
