As nonrenewable sources are getting exhausted day by day, we need to explore further areas of natural renewable energy taking into account our ever-increasing needs. Considering the urgency, a new venture is going on track by Honolulu government and business groups. Earlier Honolulu relied on fossil fuels for air conditioning purpose but after construction of this new project, they would be able to use sea water for the same purpose. The fresh water flowing in the closed loop through the building will be chilled by the pump arrangement fetching cool water from 1,600 feet below the ocean waves. After circulating through the loop, the cold seawater is diffused back into the sea ensuring apt assimilation and dilution.

As a matter of inquest we could pose concerning the maintenance requirements of the system during and after storms and the fuel going to be used to power the system. The principle of solar-powered water heaters might give us a clue in this regard. The creators have proved that the system is working fine in Sweden. Moreover prospective of cost and fuel savings from this project are remarkable.
Hawaiian Electric Company’s headquarters occur to be the first customer of this project who has been committed over half of its 25,000 ton capacity. About half of the project financing has been done by investors from Honolulu. With funding of nearly $11 M done by private investors, this $152 M project is expected to start in January, 2009.

General outlook behind this project is to make the most of renewable sources as the existing scenario demands.
