Seamus Garvey visits the 315m high Waltham transmitter in Leicestershire.

It is the same height of the new wind turbines he wants to build at sea, and Seamus thinks visiting Waltham will give him a better idea of the scale.

Normal wind turbines are about 100m high - but Seamus's turbines would be far from normal.

Instead they'd use falling weights within the blades to create highly compressed air.
