Abstract
A wind-powered apparatus includes a series of vertically extending transversely curved foils carried in a support and movable longitudinally of the support from a furled condition, where the foils are bunched closely together and present a minimum surface area to the wind, to an unfurled position where the foils are uniformly spaced along the support. The support can be rotated to take advantage of the wind direction, and the foils themselves can be rotated in unison to one side or the other. The various movements of the foils are powered by suitable drive mechanisms which may be remotely controlled.
