Flumill were the first company to use EMEC’s non-grid connected tidal test site at Shapinsay Sound in 2011. They have been developing the patented Flumill system since 2002. The system is based on a solid helix screw specifically designed for water based streams. Water streams are almost 1000 times more powerful than air and therefore require a very robust system. The Flumill systems can operate in ocean/tidal streams at less than 1m/s flow and can be adapted for use in rivers.
