The Power Collective is focused on addressing the challenges of global warming by developing practical and environmentally sympathetic sustainable energy solutions.

The Power Collective developed the RidgeBlade, a wind turbine that, instead of being located in an open field or the ocean, is mounted to the roof of a building. A roof offers a perfect place for a wind turbine seeing as air travels much faster when pushed over the peak of a roof, just as over the aerofoil on an airplane wing. The wind is forced to travel over the roof surface and forms a pinch point at the roof ridge, accelerating the airflow through the turbine.

As a result, measured wind speed around the ridge can be just over three times the actual wind speed. Placing the turbine in this high flow area means that up to nine times the energy is available compared to a HAWT (Horizontal Axis Wind Turbine) system.

The specially developed and patented design provides a simple and affordable solution to generate electricity by wind at any location for business and households. Because the turbines are mounted to the roofs of homes, they do not only need to be 100 per cent safe, they also have to be quiet and they can't vibrate.
