Listen to this very interesting interview with Professor Stephen Salter at his lab in the University of Edinburgh. Professor Salter invented a system by which wave energy is transferred to electricity.
'Thirty years after inventing a way to turn wave power into electricity, the professor fears it's now too late to rely on renewable energies to help cut global carbon emissions and prevent the melting of the arctic caps.
"We've wasted so much time not getting Ducks built when we could have been doing it properly that renewables are going to be too late," he says, looking out across the giant wave tank that dominates his university laboratory.
The first Salter Duck, created in 1973, was a rather simple teardrop design made from balsa wood. Today, the latest incarnation is a far more complex construction made from steel. But he warns, "I don't think we have time to get them working in big enough numbers in order to prevent something nasty happening to the arctic ice." '
