is implemented here”.Here the energy generator is “Peltier”. The Peltier sensor converts the thermal energy into electrical energy. The voltage is generated from the heat produced by the engine of the vehicle and the generated voltage is stored in the external battery. The stored energy is transferred to the local substation. The cost of energy complemented by the individual is added to the user account. The user can use the money for filling up the fuel in petrol bunks. Utilisation of waste heat energy is done here. Wasted heat energy from vehicles is used effectively to produce electricity. Reverse peltier effect is used for the production of electricity from wasted heat energy. Wireless power transmission of voltage is done here. Power contributed by individual is given to them as fuel.

1 .INTRODUCTION Wireless Sensor Networks (WSN) have played an important role in many monitoring and surveillance applications including environmental sensing, target tracking, structural health monitoring. As conventional sensors are powered by batteries, the limited battery capacity obstructs the largescale deployment of WSN. Although there are many energyaware approaches developed in the past decade to reduce sensor energy consumptions or balance energy expenditures among sensors, the lifetime of WSNs remains a main performance bottleneck in their real deployments, since wireless data transmission consumes substantial sensor energy. To mitigate the limited energy problem in sensor networks, researchers proposed many different efficient approaches. One method is to enable sensors to harvest ambient energy from their surroundings such as solar energy, vibration energy, and wind energy. However, the temporally and spatially varying nature of renewable energy resources makes the prediction of sensor energy harvesting rates very difficult. For instance, it is shown that the energy generating rates in sunny, cloudy and shadowy days can vary up to three orders of magnitude in a solar harvesting system. Moreover, the harvesting energy sources are intermittent and not always available. Such unpredictability and intermittency pose enormous challenges in the efficient usage of harvested energy for various monitoring or surveillance tasks.

3.1 TRANSMITTER SECTION “Peltier sensor” placed near the engine area is connected to a “Boost Converter”. The boost converter is used to amplify the voltage generated by the peltier. The generated voltage is stored in the battery placed inside the car near the engine. The DC voltage generated is converted into an RF signal and sent to the transmitter antenna.
