Traditionally, small wind turbines have had a significantly lower efficiency than their large-scale counterparts, increasing their levelized cost of energy. Diffuse Energy's product is a small wind turbine that, through being enclosed within a diffuser, can produce nearly twice the power output of existing wind turbines of the same size. Their additional diffuser also makes their turbine safer and quieter than existing turbines, both of which are key considerations for potential customers. Diffuse Energy has been supported by the ON Accelerate program at CSIRO.
