* Turbine blades are formed of durable and lightweight
composites * Rotational molding processes used with high - strength thermoplastic materials * Standard construction practices used to inexpensively build, deploy, and maintain
nacelles * Assembled with carefully selected off - the - shelf drive and generating components including brushless generators, high reliability gear trains, and double graphite / ceramic face seals for rotor shafts * Self - cleaning screen for horizontally deflecting debris and fish away from turbine blades (also designing screenless, debris immune, and more fish - friendly turbine) * Yaw bearing for bidirectional operation in tidal waters
