Year 6 Eco-Engineers really enjoyed the practical workshops during our visit to Nissan. After testing the wind turbine models we had made at school, we experimented with wind-powered vehicles to investigate the optimum ratio of power to distance. In the afternoon session, we tested electrically-powered model cars to calculate the energy needed to drive the vehicle in a controlled, forward direction. This was followed by a short, but exciting, journey in the latest model of the Nissan Leaf eco-friendly car.
