Oil Skimmers

A skimmer is a device for recovering spilled oil from the water's surface. Skimmers may be self-propelled, used from shore, or operated from vessels. The efficiency of skimmers is highly dependent upon conditions at sea. In moderately rough or choppy water, skimmers tend to recover more water than oil.A card skimmer is a device attached to a card reader, often ATMs or gas station pumps, to “skim” information about your credit or debit card. It may contain a stealth camera that records your pin as you enter it.Oil and water have very different surface tension characteristics. This makes oil skimming one of the most effective ways of separating the two fluids. Oil molecules tend to have low affinity for water molecules. This makes the molecules bond better to each other and other materials than to water.
