PowerPyramid is a hybrid wind-solar small power plant WSK, which can be placed on almost any building roof to generate electricity from the natural resources of wind and sun itself, even when the sun is low, in winter, at night, snow and rain.

The novel dual vertical-axis wind turbine makes optimum use of the wind accelerated over the roofs of the buildings. It is independent of wind direction, thus ideal at low altitudes with turbulent air flow, very quiet and no danger for birds. With the combination of wind and solar energy with the necessary technology in one device, space and costs can be reduced, making this device versatile, so on small roof areas and i. e. on lift shafts of buildings, bridges, walls etc.
