Via Kuroda Chiaki, thanks.
The Wavelight concept coverts mechanical energy captured by ocean waves into electrical energy to illuminate a series of LED lamps. Each lamp is tethered to its neighbor with a weight anchored to the sea floor. The lights are designed to attract attention for rescue operations or to warn passing ships to steer clear. A very intriguing design but are LEDs powerful enough? What happens if the anchor isn’t long enough to reach the sea floor?
