Langlee Robusto
The 132 kW Langlee Robusto™ is a semi-submersible floating installation meassuring 30x50 metres. It is floating at the water surface but most of the unit is under water, not visible from shore. The four mooring lines keeps it in position. Normal installation site is at 40-100 meter water depth. The Langlee technology utilizes the horizontal wave movement which is more powerful and esasier to catch than the vertical wave movements. The two water wings swing back and forth with the waves and are directly connected to generators that converts the wave energy directly to electricity. The power electrionics ensures compliance with grid standards, and the Robusto™ is connected to the onshore grid by a subsea cable.
