Seamus Garvey is a man with a plan.

He wants to "store" renewable energy sources such as wind and tides as compressed air in giant bags under the sea.

In this video he explains how wind turbines could be used to create compressed air.

This is pretty much just raw footage of his explanation and answers to a few of my questions - but Seamus is a good communicator and explains it well without needing any fancy editing or graphics.
