A hydro-powered ferry service could start running between south Wales and the south-west of England.

The trip writes BBC News, would venture across the Bristol Channel to link Swansea with Cornwall and Devon, is being discussed by councils in the counties.

The idea is said to be at a very early stage, however, and details remain sparse.

There is also no indication whether the crossing could also be used for goods and freight.

But if it is given the go-ahead, Swansea's council leader said it would be a "massive boost for tourism and business".

Rob Stewart said he was keen on the idea as it could "cut your travel time to Devon and Cornwall by half".

"It would have environmental benefits too: taking cars off the road and introducing green-powered ferries," he added.

The Local Democracy Reporting Service reported that just over a week ago, Labour's Mr Stewart said the council was looking at which locations in Cornwall or Devon could be used for the service.
