Tidal Sails AS

Tidal Sails resilient and extremely low weight technology platform BeamReach is adaptable to most locations by adapting distance between the two stations, spacing between sails and size of sails.  The slow-moving sails, which "reach" at 6knots 15 meter underneath the surface, are considered harmless to fish and sea mammals, and do not interfere with shipping lanes.  

Tidal Sails has carried out a range of theoretical and numerical studies over the years. These have been validated via several prototypes and test rigs, which has resulted in 4 major technology leaps since the initial drag based “Classic” solution.

BeamReach yields about the same efficiency per swept area as competitors, but is sweeping a much larger current cross section, consequently reach Rated Power already at 3knots, while regular tidal turbines only generate about 10-15% of theirs at more than 3 times the cost per installed MW.  

Due to BeamReach aggressive Peak Shaving capability at 3knots - annual production per MW is also significantly larger.

Besides, for each knot less required to reach rated power, the extractable natural resource increase by a factor of 7 (Rule of thumb) Typically tidal turbines reach their rated power at 5-7knots, which rarely even happens in a 7 knot current. 

From the above one can derive BeamReach cost level at about 1/40th of competition in 3 knots, which is as difficult to convey as to accept.
