    DESCRIPTION
    What if we could find a way to produce continuous electricity using our daily mode of transport?
    The Republic of Mauritius has an electrical consumption of around 2 600 000 kWh/ year for a population of nearly 1 348 242 inhabitants, making thus a very appreciable energy consumption of 1928 kWh/year per person.
    Concerned by the increasing demand for electricity which is estimated to grow on average by 3.43% annually for the period of 2011-2022.
    It is also noticed that in Mauritius, most households have about two cars/vehicles, both of which are used every day. These cars/vehicles are driven on our roads, sometimes making more than two travels a day…

    There comes this innovative idea of using the kinetic energy of the vehicle by applying a hydraulic system connected with a turbine coupled with a generator to produce electricity.

    Nowadays, electricity is considered to be an essential service for modern living conditions, commercial and industrial development of a country. The macro-economic effect of a continuous, reliable electricity supply of good quality has far reaching significance.

    The Government of Mauritius energy policy encourages the use of renewable and clean energy to reduce the country’s dependence on fossil fuels. Government aims to increase use of renewable resources from 20% in 2016 to 35% in 2025. Although improvement of renewable energy converters is in a fast rate, the systems to extract the wasted energy in conventional energy conversion systems are not developed as much as its technologies.

    With a view to reducing dependence on thermal plants while meeting the growing demand for electricity, another sustainable way of generating electricity is proposed: “Generating electricity by the flow of vehicles”

    SOLUTION
    Thus is proposed a new way of generating electricity by the flow of vehicles. This kinetic energy can be converted into electrical energy by use of a hydraulic system and turbine coupled with a generator. The system is functioned as follows :-
    Multiple hydraulic tubings are placed at regular intervals under the surface of roads at right angle to the flow of vehicles.
    Each pipe consists of flexible sides, a rigid base and a rigid top.
    The pipes are all fitted with an entry and exit valve for the movement of oil in the same direction.
    Considering one pipe, the process is as follows:-
    The oil enters the pipe from the entry valve.
    As the vehicle passes on the pipe, its weight creates a pressure which moves the oil through the exit valve.
    After the passage of the vehicle, the porous spongy material fitted in the pipe, returns the pipe back to its original position, allowing oil to refill in.
    As the next vehicle passes, the process is repeated.
    This whole process is carried out on all pipes.
    This overall pressure exerted, is used to run a turbine, which in turn, power a generator that produces electricity.

    BENEFITS
    In coming years, the project will prove a great boon to Mauritius, since it will save a lot of electricity of power plants
     The project “Generating electricity by the flow of vehicles” has the potentiality to produce electricity through a system that “catches” the pressure exerted by the moving cars.
     The kinetic energy, possessed by road vehicles, will, through the project be used constructively by converting it to useful electrical energy instead of allowing it to be lost in the form of heat.
     Through the project, electricity can be generated at all times, irrespective of the weather conditions. The project can work at any time of the day (24hours, 7days) since there are always vehicles on the road.
     The system will compel the drivers to slow down, hence increasing road security.
     The project will definitely reduce dependence on thermal plants and make a positive impact on our environment. The project can thus contribute to meet the increasing demand for electricity while providing a more sustainable way of generating electricity.
