    摘要： Power plant and process for the generation of electric energy through forced wind power. The plant includes a self-standing vertical structure, anchored to the ground, featuring a suitable diameter and height. Through this structure a powerful airflow operates one or more wind generators which is/are located inside. The plant is provided with several air inlets at the bottom, and an outlet at the top for discharging the air and at least one wind generator interposed between the afore-mentioned inlet -outlet. The tangible difference in the air density and temperature between high and low altitude generates a positive air flow moving from the bottom to the top and operates the internal generators regardless from the presence of winds or air flows. Suitable heating devices are located at the chimney bottom and boost the natural draught effect. A microprocessor controls the heating means in order to achieve a constant temperature at the air inlet and consequently a constant speed and a constant electric output.

    摘要： A diffuser for a wind turbine where slots in said diffuser wall entrain air to enter into the diffuser with a swirl that is counter to the internal swirl created as a reaction to the turbine blades rotation as it extracts power such that the internal swirl and the externally introduced swirl cross over each other thereby causing vortices to form between them that energizes the internal flow and helps to prevent it from separating from the internal duct wall. Such a diffuser would beneficially consist of a radial array of repeated segments each comprising a radial portion of a duct with a wing emerging from behind said duct leading edge and spiraling out and backwards and connecting back onto the wing of the next segment round such that each segment's wing connects to the trailing neighboring segment wing just as the leading neighbors wing connects onto it, and that a gap is left between the spiral arms to permit external air to flow between the trailing edge of one segment wing and the leading edge of the adjacent wing.
