Scientists have developed a way to efficiently extract uranium from seawater
Seawater contains huge amounts of dissolved metals and other substances which could potentially be useful, but which have remained too expensive to extract in large amounts. Now, scientists with the Oak Ridge National Laboratory (ORNL) in Tennessee say they have developed a new material which could lead the way to the efficient extraction of dissolved uranium from seawater, providing a huge source of uranium to power nuclear reactors.

“We have shown that our adsorbents can extract five to seven times more uranium at uptake rates seven times faster than the world’s best adsorbents,” said Chris Janke, of the ORNL’s Materials Science and Technology Division.

The material, called HiCap, is produced by combining adsorbent materials produced by the ORNL with high surface area polyethylene fibers. The fibers are able to quickly and selectively pull dissolved metals from the water. The new adsorbent materials are more economical than any previously developed technology to extract substances from seawater, according to the ORNL.

Re: Scientists have developed a way to efficiently extract uranium from seawater
What can uranium do to you?
 Quoting: Barbara P. Strigoi


Uranium is a radioactive element used in creating nuclear fission reactions. It is commonly used in nuclear power plants to generate energy, but also for nuclear weaponry.

Applications of uranium:

- nuclear fuel for nuclear power reactors
- explosive and yield booster in nuclear weapons
- material for armor and armor-piercing projectiles
- catalyst
- additive for glass and ceramics (to obtain beautiful green or yellow colors)
- toner in photography
- mordant for textiles
- additive for the preparation of biological samples for electron microscopy
- shielding material (depleted uranium)
- ballast (counter weights)
and other minor applications [link to wiki.answers.com]

Re: Scientists have developed a way to efficiently extract uranium from seawater
Good god, perfect example of net loss energy source on steroids.

They can get gold from the oceans and synthesize it too but the cost of the energy and resources to do so would completely defeat the purpose of doing it in the first place.

You know, like mining for hydrocarbons on other celestial bodies.

The notion is absurd.

Most "scientists" these days are more worried about where there next grant cheque is coming from than real science.

 Quoting: Anonymous Coward 31592020


I agree with this, breeder reactors, recycling spent uranium, etc existing reactors utilize 60's technology are inefficient and produce too much waste.

However, large scale plants will prohibit development of the technology. Large scale utility projects usually/typically require government financing. That means the government stipulates (specifies) the technology used or if the project even gets funded. That also means the corrupt crony system we have gives the corporate interests that run this world a monopoly over what resources are used in the generation of energy. There is far too much entrenched wealth in the fossil fuel infrastructure. Fossil fuels are far more easier to control for them in commodities markets, and the scarcity of these materials gives them easy pretext for generating continual wars in various regions of the world.

Also, when one looks at the cost/benefit ratios of any large scale public improvements project (energy, infrastructure, etc) you must understand that the money/credit invested needs a return from the final product to be conducive (foundation) for growth benefiting from the improvement. As it stands now there is far too much global debt for planned public improvements projects to be long term beneficial or positive in return for credit allocated. Interest rates need to be suppressed to keep government financing low as their existing debt burdens have become unsustainable. This means the amount or frequency of large scale improvement projects will continually decline ending in a downward spiraling decay for most public utilities and levels of service.

Obviously a better solution are small, compact and portable units that can deliver energy to small communities, neighborhoods or single family residences. I remember an article back from about 2008 that a Chinese company was going to produce small nuclear units to power small communities or even blocks. The question then is if these companies can overcome entrenched aggregated wealth in the fossil fuels dependency.

Re: Scientists have developed a way to efficiently extract uranium from seawater
Worldwide, we know of enough uranium to power today's nuclear reactors for another 100 years, according to the Nuclear Energy Agency. But scientists say there may be a thousand times as much uranium lurking in the oceans, dissolved in seawater. Problem is, how do you harvest it? Some attempts have been made with plastic threads that attract the mineral.

But a better way might be to fish it out with nanofibers of chitin—the stuff shrimp and lobster shells are made of. Rather than start from scratch, researchers spun threads of chitin from liquefied shrimp shells. They chemically modified the nanofibers to make them stick to uranium, and dropped them in uranium-spiked water. After three days, they found that the shrimp-shell fibers had indeed collected uranium from the solution. They presented that research at a meeting of the American Chemical Society (pdf).

PHILADELPHIA, Aug. 21, 2012 — Scientists today reported progress toward a 40-year-old dream of extracting uranium for nuclear power from seawater, which holds at least 4 billion tons of the precious material. They described some of the most promising technology and an economic analysis showing uranium from the oceans could help solidify nuclear energy potential as a sustainable electricity source for the 21st century. Their reports were part of a symposium at the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, being held here through Thursday.

They can and have these units are called desalination plants. The problem is the amount of energy required in the desalination process. My friend developed a process that utilizes tidal energy for a de-salination plant. His process was almost 100% energy independent meaning the desalination process and appurtenant energy needs we are supplied by tidal energy. The short end of the story is he never got any real financial backing to construct a plant, had some interest in Honduras but nothing ever transpired.

Believe it or not but the aggregated wealth in this world totally controls what form of energy you use and how it is generated and delivered to you. If that form of energy does not fit into their overall web or network of monopolies and control it isn't going anywhere, period.

Neither Hiroshima, nor Nagasaki, nor Fukushima, will ever change that.

China is building one of the biggest nuclear power plants in the world right now and hundreds will follow.

If you still want to worry about radiation though, worry about gamma rays from space.
