Greenbird Wing system

Using the lessons learned during the Windjet / Greenbird project, Photon has created a wing system for wind assist propulsion of commercial shipping.

The Greenbird Wing Power System could be used as a sole means of propulsion on slow platforms, but is designed to be most effective when combined with a powered vessel to provide auxiliary propulsion. Harnessing any crosswind component of the apparent wind, the greenbird wing autonomously provides additional propulsion, resulting in considerable fuel savings. Calculations predict 20-40% savings are possible in the case of fast passenger ferries in San Francisco bay.

The fully autonomous wing system is simply turned on or off with a switch on the bridge. In the OFF, or 'feather' mode the wing is exceptionally low drag and will not affect the vessel's maneuverability or handling characteristics. In ON or 'power mode, the wing will automatically trim itself to make best use of the available wind, regardless of the vessels heading or speed.

A prototype 45' wing, pictured above is currently being evaluated by Wind and Wing Technologies and Berkeley University to assess its potential impact on Bay Area ferries.

The Greenbird wing power system from Photon Composites Inc is Patent Pending.
