A wave-driven generator with virtually no moving parts could make wave power a more efficient and competitive form of renewable energy.
The key to the device, dubbed the Snapper, is the way it converts a slow, steady wave motion into an efficient current-generating jackhammer-like action.
Experiments on a prototype suggest that much smaller generators could be built for the same output, reducing costs.
The increased efficiency of the device should help to make wave-powered generators competitive with other renewable energy sources, such as wind power, as well as with fossil fuels.
