The floating desalination machines powered by the waves

"The ocean is an unforgiving place," says Susan Hunt. "But our technology is designed to operate there - it goes up and down in the waves, all day and all night." Ms Hunt is chief innovation officer for a Canadian start-up called Oneka Technologies. It has developed floating desalination systems that turn seawater into fresh water. While large, shore-based desalination plants typically require vast amounts of energy to remove the salt, Oneka's small units are powered solely by the movement of the waves.

Japan's Fukushima nuclear plant prepares to release diluted radioactive water into the sea

Japan's Fukushima nuclear plant prepares to release diluted radioactive water into the sea

At Japan's tsunami-wrecked Fukushima Daiichi nuclear plant, giant blue pipes have been constructed to bring in torrents of seawater to dilute treated, radioactive water under a plan to discharge it gradually into the Pacific Ocean. Workers were making final preparations as Associated Press journalists received a rare opportunity Friday to get a look at key equipment and facilities for the release, expected in coming weeks or months.

Japan nuclear plant conducts tests before discharging treated radioactive wastewater into sea

The operator of the wrecked Fukushima nuclear plant began tests on Monday of newly constructed facilities for discharging treated radioactive wastewater into the sea, a plan strongly opposed by local fishing communities and neighboring countries. The tests at the Fukushima Daiichi nuclear power plant use fresh water instead of the treated water, operator Tokyo Electric Power Company Holdings said. Plant workers examined pumps and emergency shutdown equipment at the newly constructed seaside facility, which will dilute the treated water with large amounts of seawater. The diluted water then enters an undersea tunnel and is released into the ocean about 1 kilometer (0.6 miles) from the coast.

Predicting and alerting for coastal flooding

Predicting and alerting for coastal flooding

In response to increasing coastal flooding risks, the Meteorological Service of Canada (MSC), a branch of Environment and Climate Change Canada (ECCC), recently launched a five-year initiative entitled the Predicting and Alerting for Coastal Flooding (PACF) project. To help advance this work, ECCC is seeking Geographic Information System (GIS) data from municipalities and regional districts that pertains to near-ocean infrastructure.

Marimaca Secures Water Option for Life of Mine Seawater Supply

Marimaca Secures Water Option for Life of Mine Seawater Supply

Marimaca Copper Corp. (“Marimaca Copper” or the “Company”) (TSX: MARI) is pleased to announce that it has entered into a water option agreement to secure the future water supply required for the Marimaca Copper Project (the “Project”) in Chile. Under the agreement, seawater would be supplied following its use in cooling systems at an electricity plant in Mejillones, located 25km from the Project and operated by one of Chile’s largest energy suppliers. The option has a term of 5 years, with the ability to extend for 2 years, and will allow the Company to advance final Project permitting and technical studies, including water pipeline studies that are already underway.
