A friend of mine worked with Prof. Salter. He's an incredibly brilliant, smart and kind scientist. Unfortunately, much of his research was 'blocked' due to someone miscalculating the cost by twice the amount, starving the research field of funding until recently. There are quite a few related spin-outs (e.g. Pelamis Wave, website currently down). Edinburgh also just got a huge wave tank for more experiments (http://www.bbc.co.uk/news/science-environment-27702506).
