A device for collecting energy from wind includes an airfoil formed from a tubular member with a circular cross-section and a substantially planar leading edge. As an airflow passes over the airfoil, from the substantially planar leading edge to a trailing edge, a Bernoulli effect reduced pressure region results adjacent one or more slots. The slots are positioned directly behind the leading edge and extend to a section of greatest diameter of the airfoil. This Bernoulli effect reduced pressure region in combination with counter-rotating eddies formed by the front leading edge cause air to be drawn out of the tubular member. An airflow driven turbine capable of converting an airflow into rotational mechanical energy is connected to an interior of the tubular member though air passageways. A flow of air is drawn though the airflow turbine and through the air passageways by the Bernoulli effect and the counter-rotating eddies created by the airfoil. The flow of air through the turbine is converted into rotational mechanical energy.

[ What is claimed is:] [1.]1. A device for collecting energy from wind comprising:an airfoil formed from a tubular member with a circular cross-section, the tubular member having an elongated opening extending parallel to a longitudinal axis of the tubular member, and a substantially planar leading edge spaced from and positioned in front of the opening, the leading edge having a width which is equal to or less than a diameter of the tubular member;an air passageway extending through at least one slot between the tubular member and the leading edge, through the opening, and through an interior of the tubular member to an air duct which allows air to be delivered from a turbine system to the airfoil; anda support structure for rotatably supporting the airfoil, the support structure orienting the airfoil so that the planar leading edge is facing into the wind.
