Harnessing Fiji hot springs for refrigeration (University of New South Wales)
Two remote off-grid villages on the tiny Fijian island of Vanua Levu are looking forward to their first reliable source of refrigeration thanks to, rather ironically, their local hot spring.
The plan for this pilot project is to pipe the Waikatakata Hot Spring at Vusasivo, which is coming out of the ground at 70°C, into an absorption chilling facility at Natewa Bay.
This centralised cold storage facility will then be available for villagers to preserve their goods.
The geothermal freezer facility plans to service the traditional landowners of Vusasivo Village and adjoining Natewa Village in coordination with the Nambu Conservation Trust of Natewa.
