Skimming

The first Seaswarm prototype being tested in the Charles River in mid-August 2010 (Image: ...

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 ADT Anti-Skim™ ATM Security  device

The theft of financial information during ATM transactions is one of the financial industry's fastest growing crimes and in the latest effort to combat this problem, ADT Security Services today introduced a new advanced skimming detection device for financial institutions throughout North America. The ADT Anti-Skim™ ATM Security Solution helps prevent skimming attempts and detects skimming devices on all major ATM makes and models, says ADT.  Read More
