Wave power is a form of renewable energy that may be harnessed for use in electricity generation. Capturing the energy of ocean surface waves and converting it into a useable form of electrical energy is a difficult task, and a major technological breakthrough is necessary for it to contribute significantly to the world’s energy needs. Salter’s Duck, invented in 1974, remains the device against which all other wave energy systems are measured. Why did wave power funding dry up in the 1980s? Discuss
