 Everybody knows what normal sails are like. They're just fabric and they're one side of a wing. The wind's got a tremendous amount of power in it. The wing is a hybrid system. It's not intended to completely replace the motors. The ferries in the Bay Area, I think they use a mere of a million dollars worth of fuel per year to save 30 to 40 percent of the fuel costs. The San Francisco Bay is a playground of wind. We absolutely have got to stop pumping carbon dioxide into the atmosphere.
