The methods, which generate energy from the movement of road, rail or air vehicles, utilise a number of small devices to collect energy which can be sent to the electrical grid system or used to power street furniture. Energy may be collected by piezoelectric ribbons 4 mounted on conductive rubber 5 running across the road/rail 1. Alternatively, strips of magnetic material of one polarity may be set across the road so as to create a voltage when a vehicle fitted with a magnetic device of the opposite polarity passes over. Magnetic rollers or vertical vanes may be designed to rotate in response to passing vehicles. A passing vehicle may compress strips filled with gas/fluid so as to turn small generators or may cause turbines to rotate. Alternatively small turbines may be located in drainage pipes so as to be activated by storm water runoff.
