Among renewable energy sources, ocean wave energy has not been utilized much, although it is known that its conversion efficiency into electricity is the highest. The US Air Force Academy is testing large converters with efficiency up to 99 %
According to the Russian website Rbc, scientists at the US Air Force Academy have completed a large-scale experiment on operating a device that converts ocean wave energy into electricity. The initial results have confirmed the complete possibility of building a machine with unprecedented performance.
The converter test has demonstrated the plausibility of the structure and the ability to achieve an efficiency of 99, calculated on a computer model. In fact, the device is capable of capturing energy and quenching waves and converting that energy almost entirely into electricity. For comparison, it should be repeated that the maximum efficiency of modern wind power equipment is only about 60.
The project to deploy ocean wave conversion technology started in 2008. For the first time in the world, a transducer operating in submerged state was tested with a scale of 1: 300 compared to with the scale of future industrial equipment. Currently, the US Air Force Academy has tested a continuous device, 1:10 scale compared to industrial equipment later. This is the last step before a fully-fledged full-size machine can be built out at sea.
