Hydro Tasmania has signed a deal with Sydney-based company BioPower Systems to conduct trials of its BioWave technology on King Island and its Biostream tidal-current system on Flinders Island with a view to generating 250kW of electricity to power the 500 homes on both Bass Strait islands by next year.

BioStream technology mimics the movements of shark, tuna and mackerel but fixed in a moving stream. The resulting motion generates power.

BioWave is based on the swaying motion of sea plants in the presence of waves. The motion of oscillating blades produces power.

BioPower Systems Chief Executive Officer, Tim Finnigan, said that the ocean power could be provided at the same cost as the islands’ existing power supplies.
