This giant outline of a car has been etched into a field in north Suffolk as part of a land art project to get people thinking about renewable energy.

The marking spans 200m in size and looks as though it is being powered by one of the turbines situated on Eye Airfield - which raises questions about whether electric cars could ever be powered directly by turbines.

The artwork is the most recent collaboration between Eye residents Carlo Roberts and Stefan Fulcher who have previously etched a B-17 bomber - which flew from the airfield during the Second World War as part of the 490th Bomb Group - onto a field in the area.

Mr Roberts, a geography teacher at Sprowston High School and who also has a background in community art, said he was interested in art that relates to the locality and views from above.

The 49-year-old said: 'Ever since I did an art degree as a mature student I've been obsessed with aerial views. What I was really interested in was combining a real object with a drawn object.

'After a trip to London, I was amazed at the amount of electric cars there, it got me thinking about electric cars and how few there seem to be in the countryside.

'The idea of having a turbine powering a car seemed very interesting.'

The pair's first piece of land art saw the Olympic rings drawn into the earth to celebrate London 2012. They also drew a remembrance poppy in 2014.

Their most recent etching was given the green light by landowner Tom Baldwin.

Mr Roberts used satellite maps to produce a scale drawing of the outline before heading out into the field with the help of 16-year-old student Samuel Seymour.

After spending five hours marking out the base line of the electric car in the wheat stubble, they scaled up the original drawing using a surveyor's instrument to measure the angles to set out reference points for the tractor driver to follow.

The outline was then ready for Mr Fulcher to plough in using a set of discs used to break up and cultivate top soil - this process took just 90 minutes.

Mr Roberts said: 'What's brilliant about the fields is you get a lot of straight lines on them where the wheat was planted and tramlines every 24 metres or so.

'It wouldn't have happened without Stefan and Tom. Stefan is the skill behind it; he's got a very good eye. I'm just amazed and feel very privileged that I can do it.'
