In 2008, SuperPower, Inc., an electric power component manufacturer in Schenectady, New York, produced a 1,311 meter (.814 mile) length of HTS wire, a new record for the industry. SuperPower recently completed the Albany Cable Project in which a 350 meter (1,148 feet) HTS underground cable was installed in the National Grid power system connecting two substations in Albany, New York. 

Until recently, halogen-free products were only available in Europe, but Sony has now adopted global design specifications to ensure that all their projects meet the same standards. Sony aims to have all product lines free of brominated flame retardants by the end of 2005 if substitutes are found to be safer. They also aim to phase out all uses of polyvinyl chloride (PVC) by 2005 as well as lead solder, and specified heavy metals. For example, a Walkman model has PVC-free cables and no brominated flame retardants or lead solder in the printed circuit board. 

The first applications were based purely on experience from previous smaller projects. Since recently, more well-documented design criteria are available. Stability criteria for these units were determined based on analytical and experimental studies. For high energetic wave sites the units can be hydraulically anchored with cables to the sea bed. Wave transmission was studied in Canada. Technical design aspects are treated by Harris. ...
