Use some of the energy to desalinate water from the Gulf of Mexico and the Pacific Ocean and ship it through pipelines to thirsty towns, businesses and new farms along the entire border zone. (scientificamerican.com)
AbstractSince the 1980s, the occurrence of harmful algae blooms (HABs) in the Persian/Arabian Gulf has increased concurrently with the rapid expansion of Gulf seawater desalination. (civilengineering365.com)
Here, the hypothesis that seawater desalination has strengthened Gulf exchange influx, probably leading to accelerated horizontal advection of established HABs in the outer ocean basin into the Gulf and enhanced HAB dispersal within the Gulf, is examined. (civilengineering365.com)
These results support the above-stated hypothesis and suggest a linkage between Gulf seawater desalination and the recent shift in the seasonal regime of Gulf HABs. (civilengineering365.com)
This causal mechanism for the increase in Gulf HABs highlights the need for a basin-scale management strategy to monitor and forecast the Gulf's state under the stresses of seawater desalination and provide early warning signs of environmental problems. (civilengineering365.com)

This large-scale Captura facility, shown in an artist's rendering, could capture gigatons of carbon dioxide dissolved in ocean water. (ieee.org)
The dock belongs to the ocean research institute AltaSea and the barge to Equatic , which is testing a daring new idea to remove carbon dioxide from the atmosphere-by sucking it out of the seas. (ieee.org)
The oceans are a vast carbon sponge, absorbing a quarter of global CO 2 emissions. (ieee.org)
Carbon in ocean water is present at a concentration 150 times as high as in the atmosphere. (ieee.org)
But Equatic, Captura and others are trying to prove the concept's viability with backing from the Chan Zuckerberg Initiative , Gates Foundation , oil and gas companies, and the Advanced Research Projects Agency-Energy (ARPA-E) . Pulling carbon out from ocean water, where it is present at a concentration 150 times as high as in the atmosphere, is more efficient than air capture, says Captura's CEO Steve Oldham. (ieee.org)
Both companies say they could remove carbon from oceans for around $100 per tonne, the U.S. Department of Energy's target for its carbon-negative moonshot initiative . (ieee.org)
This reduces ocean acidification and boosts ocean carbon buffering. (verdict.co.uk)
Since most electricity comes from fossil fuels, these larger desalination plants often contribute a considerable amount of carbon emissions. (renewableenergymagazine.com)

The only other currently used desalination treatment is of the thermal variety. (wateronline.com)

It continually draws in seawater, separating 1 percent of it for conversion to concentrated brine, which the company puts through a proprietary electrodialysis machine. (ieee.org)

Because ocean water has a higher CO2 concentration than air, it can capture more CO2 in a smaller volume. (verdict.co.uk)
The ocean reserves nearly four billion tons of uranium, providing an inexhaustible supply of nuclear energy if the limits of ultralow U(VI) concentration (3.3 µg·L-1) are addressed. (bvsalud.org)

It converts brine into a solution for de-acidifying the ocean using renewable energy. (verdict.co.uk)

The ocean covers over 70 percent of the Earth's surface and contains over 95 percent of the planet's water, except this water contains salt and is not suitable for human consumption. (linex.com)
Even with all of the water in Earth's oceans, we satisfy less than half a percent of human water needs with desalinated water. (idsemergencymanagement.com)

One popular solution has been the construction of plants to remove salt from water sources such as seawater. (go.com)
Now scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) investigating how to make desalination less expensive have hit on promising design rules for making so-called "thermally responsive" ionic liquids to separate water from salt. (impactlab.com)
New method devised using a small electrical field that will remove the salt from seawater. (impactlab.com)
Chemists with the University of Texas and the University of Marburg have devised a method of using a small electrical field that will remove the salt from seawater. (impactlab.com)
Seawater has up to 3.5 percent salt and other unwanted elements like silica, color, and microorganisms. (ampac1.com)

The extraction of minerals from hypersaline brines generated as by-products of seawater desalination plants has attracted the interest of scientists. (chemistryviews.org)
Now new research from Stanford scientists demonstrates a new method for making hydrogen fuel directly from ocean water. (impactlab.com)

Additionally, the team will develop a small-scale WEC that can be rapidly deployed for both power generation and seawater desalination close to shore. (hawaii.edu)

Faced with global warming and potential oil shortages, the US navy is experimenting with making jet fuel from seawater. (impactlab.com)
Roughly 40% of the global population lives near a coastline, making desalination a relevant option for more than 2 billion people. (renewableenergymagazine.com)

The skyscraper is powered exclusively by a closed-loop, waste-to-energy system fueled by captured ocean pollution and onsite waste. (evolo.us)
The new funding further supports HNEI and UH researchers to advance a number of research projects such as a power generation and management system for a floating Oscillating Water Column WEC , designed for applications such as ocean observation, navigation and equipment recharge. (hawaii.edu)

These seawater desalination systems are typically utilized by coastal communities, providing a practically limitless supply of feed water. (wateronline.com)

Heimdal is taking a different approach and works with the ocean. (verdict.co.uk)

Using seawater desalination RO treatment systems, coastal communities and island nations can achieve clean and safe water. (wateronline.com)
NCCOS delivers ecosystem science solutions for stewardship of the nation's ocean and coastal resources to sustain thriving coastal communities and economies. (noaa.gov)

There are numerous other examples of experimentation in desalination throughout Antiquity and the Middle Ages, but desalination was never feasible on a large scale until the modern era. (wikipedia.org)
However, new research from the United Nations University Institute for Water, Environment and Health in Canada is warning that a byproduct of these desalination plants -- super-salty, potentially toxic brine -- is being produced in large quantities and that it could pose serious environment al threats. (go.com)
Desalination plants range from small to large industrial or municipal facilities. (giiresearch.com)
Even very large desalination plants are in fact quite small and can easily fit onto a platform. (planetforward.org)
