Although it may have missed the entry deadline for the Wendy Schmidt Oil Cleanup X-CHALLENGE, a new technology for containing oil spills at sea was recently unveiled. Developed by Norwegian research organization SINTEF, the system uses a curtain of air bubbles to contain spilled oil for easier removal, or to form a barrier around protected areas.  Read More

Koseq's Victory Oil Sweeper is one of ten technologies competing in the Wendy Schmidt Oil ...

If there was one thing that last year's Gulf of Mexico oil spill showed us, it was that there were no particularly good systems in place for containing and removing such spills while the oil is still out at sea. One year later, although many companies and individuals have come forward with their concepts for such systems, little has actually been developed to the point of being ready for deployment. In order to generate some incentive, and provide financial support to the cream of the crop, the X PRIZE Foundation is now in the midst of its US$1.4 million Wendy Schmidt Oil Cleanup X CHALLENGE. Although the competition has been under way since January, the ten finalist teams were announced just last week.  Read More

The Lubricheck analyzes the capacitive and resistive properties of engine oil samples, to ...

Imagine if every time you bought a pair of socks, you automatically threw them out after six months, regardless of their condition. While you would certainly always have newer socks, you would also likely end up throwing away quite a few pairs that could have lasted a while longer. When it comes to changing the oil in our vehicles, most of us do take the “every X miles” approach, however, as there’s no easy way of telling if that oil really needs to be changed ... or is there? The designers of Lubricheck claim that their device will save money and minimize discarded oil, by analyzing samples of engine oil and letting drivers know if it’s still good.  Read More

The United States imports approximately one million barrels of oil per day from Canada, which is about twice the amount that it gets from Saudi Arabia. A large percentage of that oil comes from tar sand deposits, in which bitumen (a tar-like form of crude oil) is found combined with sand. The tar sands – also known as oil sands – are hugely controversial, as many people state that the process used for extracting the oil from the sand is too ecologically-unfriendly. A new technique being pioneered at Penn State University, however, could drastically reduce the environmental impact of that process.  Read More

The MOSE (Mechanical Oil spill Sanitation Equipment) oil spill vacuum

The Deepwater Horizon oil spill earlier this year prompted many researchers to concentrate their efforts on developing better ways to clean up oil after such disasters. We’ve looked at approaches such as autonomous robots and underwater separators to collect the oil while it is still at sea, but students at the Norwegian University of Science and Technology (NTNU) have developed a novel approach to dealing with the oil once it winds up on shore – a vacuum cleaner.  Read More

Over 800 skimmers were deployed in the Gulf of Mexico during the summer of 2010 to help clean up the Deepwater Horizon leak; however, it is estimated that these skimmers collected only three percent of the surface oil. Researchers at MIT have devised a system, called Seaswarm, consisting of a fleet of vehicles that may make cleaning up future oil spills both less expensive and more efficient than current skimming methods. A robotic prototype created by the researchers could autonomously navigate the ocean surface using cutting edge nanotechnology to collect surface oil and process it on site.  Read More

EVTN's Voraxial 4000 Separator uses centrifugal force to separate oil from water

Last week, Florida-based Enviro Voraxial Technology (EVTN) announced that it has received a purchase order from BP for an underwater version of its Voraxial 4000 Separator. Mounted on a skimmer vessel, the machine takes oil-laden water from the sea and spins it at high speed in a central cylindrical chamber. The resulting centrifugal force pulls the water to the outer edges of the chamber, leaving the oil in the middle. Once separated, that oil is then captured and stored in onboard holding tanks, while the water flows back into the ocean. BP wishes to try out their single 4000 on a trial basis, with an eye towards using multiple machines for cleaning up the Gulf of Mexico oil spill.  Read More

The computer animation's prediction of the oil spill after 360 days - April 15 2011 (Image...

With oil from BP’s Deepwater Horizon oil rig continuing to spew into the Gulf of Mexico researchers from the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaii at Manoa have produced an animated computer simulation that shows the potential spread of the oil over a period of 360 days from when the spill started. To calculate the particle dispersal the researchers used ocean flow data from simulations conducted with the high-resolution Ocean General Circulation Model for the Earth Simulator (OFES).  Read More

The BP oil spill, as shown in a NASA satellite image

Whether it's reaching orbit, landing on the moon, building more efficient cars or speeding up human genome sequencing, the X PRIZE has become synonymous with driving innovation. Now there's another scenario that's crying out for the kind of radical breakthrough theses prizes are designed to achieve – the oil spill crisis in the Gulf of Mexico. The X PRIZE Foundation is planning to answer this call with a new prize aimed at incentivizing privately-funded methods to quickly clean up crude oil from the ocean and coastlines around the spill.  Read More

The polymer-based filter blocks oil and allows water through

With the damaged Deepwater Horizon oil well continuing to spew oil into the Gulf of Mexico there’s no shortage of suggestions coming from those concerned about the environmental disaster. We’ve already looked at a number of clean-up options, and now a University of Pittsburgh engineering professor has developed a technique that looks very promising. His filter for separating oil from water not only cleans the water, but also allows the oil to be recovered and stored for the use BP originally intended and the filter to be reused.  Read More
