A vertical axis wind turbine having a plurality of blades around its periphery and a pivotable door associated with each blade. Each door has a pivot axis that is inclined outwardly toward the bottom of the turbine so that gravitational forces will pull the doors toward an open position. The doors are designed to move toward a closed position to at least partially block wind forces from the blades when the rotor rotates at potentially damaging speeds. The turbine has mating coils on the rotor and the support column to generate electrical energy when the rotor rotates.

[ What is claimed is:] [1.]1. A vertical axis wind turbine comprising:a vertically oriented support column;a rotor mounted on said column, said rotor including a plurality of blades spaced circumferentially around the rotor; anda plurality of doors hingedly mounted on said rotor around its periphery, with one of said doors between each pair of adjacent blades, each of said doors having a hinge axis located near the outer edge of one of said blades and inclined outwardly toward the bottom of the rotor, whereby the force of gravity pulls each said door to pivot about said hinge axis toward the center of the rotor.
