National Second prize winner


an Oceanic Thermal Energy Extraction Project


Idea description

The idea behind Green Water is green sustainable energy harvesting from seawater or similar large bodies of water. It is fossil fuel free and can potentially save up to 90% power consumption compared to conventional A/C facilities.

The core innovation is to exploit the temperatures of the seawater and use it as a thermal energy reservoir. The energy is either harvested by drawing in seawater through a series of pumps and heat exchangers, and then distributing the energy, directly to the A/C facility, or sent to an integrated heat pump, hereby producing the needed heat, which is necessary.
