The invention pertains to energy production by capturing simultaneously water potential (surface height differences due to waves) and kinetic (flow of water due to e.g. waves, tide or streams) energy. The plant can have tidal compensation () to avoid energy flux streaming over the plant in high tide, and directional stabilizing arrangement to turn it automatically parallel to wave crests. Surfaces capturing energy from flow have optimized movements to follow speed of water in different depths. Also energy conservation to filter output ripple can be arranged with twin-phase fluid accumulators ().

Hybrid energy plant

A bogie for a railway vehicle comprising of at least two articulated, pivotable and rotatable wheel body parts (2, 3) including wheels or a set of wheels (4, 5) mounted in bearings and the supporting body (6) of the bogie being connected to the parts by a suspension (9a, 9b) of the railway vehicle. In the bogie, two wheel body parts (2, 3) have been resiliently interconnected from their side constructions by two stabilizer constructions (16) both of which have been articulated to the supporting body (6).
