Flower Turbines develops compact vertical-axis wind turbines for distributed renewable energy generation in built environments, rural sites, and off-grid applications. Its tulip-shaped turbines are designed to be quiet, visually unobtrusive, bird-safe, and suitable for clustering near homes, businesses, marinas, rooftops, and other locations where conventional wind turbines are often impractical. The company’s core technology includes patented aerodynamics and its “Bouquet Effect,” in which neighboring turbines are arranged to improve one another’s output; Flower Turbines states that five clustered small turbines can produce 228% more energy than five separate units
