Although late in coming to the market, the Parris-Dunn wind generators had a unique feature that made them very successful. Dunn's "slip-the-wind" idea provided a simple, inexpensive and effective way of governing propeller speeds in variable and dangerous wind conditions. The propeller moves back on its axis and allows wind to bypass the blades while still keeping the generator at a relatively constant speed.
