(PhysOrg.com) -- Ocean waves can be incredibly strong and very difficult to block completely. When a wave moving across the ocean interacts with a buoy, the wave can be slightly dampened, but will still pass by if its wavelength ...
The increased requirements on efficient production of clean energy have introduced the necessity to develop new power plant concepts. The basic functionality of the new ideas is tested in small scale pilot plants. Advanced ...
