Seamus is a professor of dynamics at the University of Nottingham.

Over the next 12 months he'll be working on a plan to harness renewable energy sources (wind, wave and tides) and store it as compressed air in giant bags under the sea.

Science fiction or science fact? Seamus certainly makes a strong case and is chasing funding to test his plans.

This video was shot during my first meeting with Seamus when I asked him the "10 questions" I'm putting to all scientists.

This is just a selection of his answers.
