A Cost-Effective Wind Generator

This cost-effective wind generator is a sound investment for cutting your utility bill.

As a means of overspeed control in strong winds, Marshall designed his tail frame so it could be folded parallel with the blades if necessary. In the partially furled position, the tail vane directs the rotor into the wind at an angle, thus shunting off much of its force.
