Omnidirectional vertical-axis wind turbine

An omnidirectional, vertical-axis wind turbine comprising:

• A) base means for forming two vertically juxtaposed and interconnected chambers,
• B) shaft means connected to said base means and extending vertically through said chambers for rotation about an axis,
• C) horn means connected to said base means having inputs for receiving the wind from different directions and outputs for directing the received wind into a first of said two chambers.
• D) first energy conversion means in said first chamber and attached to said shaft means for converting energy of the wind in said horn means into a first component of mechanical energy for rotating said shaft means and for deflecting the wind toward said second chamber as a primary exhaust air with vertical and angular velocity components,
• E) redirection means intermediate said first and second chambers for redirecting the primary exhaust air to produce a substantially laminar flow toward said second chamber, and
• F) second energy conversion means in said second chamber and attached to said shaft means for converting the energy in the laminar exhaust into a second component of mechanical energy thereby to increase the total mechanical energy transferred to said shaft means.
