Aerated approach to oil spills

A "curtain" of air bubbles could be the key to future oil-spill cleanup as the approach works even in the face of strong winds and currents "pooling" together spilled oil for retrieval. The curtain of bubbles is generated by a 12 by 1.5 meter grating covered in perforated rubber air-hoses that release bubbles generated by a compressor. The system developed by SINTEF, an independent research organization in Scandinavia, in conjunction with industrial partners, including Statoil has been demonstrated to be effective even in gales and where strong currents are present in the Skarnsundet Sound in the Trondheim Fjord.
