The main component is a hose floating on the water’s surface, following the movements of the waves. Alternately letting in sea water and air into the hose creates water and air batches that “surf” inside the hose.

The water batches surf inside the hose and the water’s movement builds up energy in form of pressure. At each wave trough, a new water batch give rise to the pressure build up. The hoses are a few hundred meters long and are angled relative to the wavefronts. This is why Vigor can absorb so much more energy than, for example a buoy that only can extract a few meters of the wavefront.

At the end of the hoses the pressurized waterbatches are collected and led through one common turbine, which drives a generator. The sea water is returned to the ocean and wave energy is converted to renewable electricity.
