Ducking The Issue

Far from being a euphemism for some obscure act of violence, an ‘Edinburgh Duck’ is in fact a wave-power generator designed in the 1970s. The old design is being revamped as a self-powered desalination device which its inventor hopes will benefit countries that have to rely on power-hungry desalination plants for their fresh water supplies. Whether the Duck can compete against these large-scale projects while staying affordable remains to be seen.
