Scientists develops oceanic energy collector, inspired by design of shark tails

Washington, May 22 (ANI): A scientist has designed a radical oceanic energy collector, which is inspired by the design of shark tails.

According to a report in ENN (Environmental News Network), Tim Finnigan, a professor of ocean engineering at the University of Sydney in Australia, constructed the device that seizes the power of the sea by mimicking the successful evolutionary design of the fish species.

Known as the BioStream, the deisgn of the device has been modeled after the most efficient tailfins the sea offers, that of tuna and sharks. The fins are crescent-shaped and stiff and effectively generate a powerful and seamless thrust.

The device works rather simply.

It is anchored into place in the sea bed with 32-foot rock-bolt anchors. Utilizing a smart and effective cable and pulley system, the BioStream device is tugged toward the sea floor and latched into place via an autonomic latching mechanism.

The installation process from start to finish takes less than three days to complete.

As the ocean current undulates, the BioStreams mechanical tail works on this force freely from side to side. A gearbox converts this oscillation into unidirectional motion to drive a magnet generator for power production.

BioWave, another device designed by Finnigan, works in a similar fashion.

Inspired by kelp, it rests on the sea surface to harness the power generated from the rolling waves, which uses a generator similar to that of the BioStream. The endless motion of the ocean is all that is needed to harness this power.

Both of these models shift accordingly to utilize the flow of the currents as they shift. These efficient and mimicked bio-designs are extremely hardy thanks to the time tested shapes that have weathered the seas for long.

BioPower Systems, founded by Finnigan, is developing three different versions of each design for serious and varied sea-power generation.

The largest generator design, which is quite large, two megawatts to be precise, is capable of producing enough power to service some 1600 plus homes, claims BioPower.

The benefits of these devices are that they harness power naturally and dont pollute the environment or ruin beachfront views. (ANI)
