Jagath Wijesekara, External Board Member of the Sabaragamuwa University of Sri Lanka, invented Free Electricity Generation System, through extensive research and development continued for nearly two years. The research paper on the generation of free electricity by converting the gravity and acceleration of moving road vehicles into static electricity, was presented to Power and Energy Minister Dallus Alahapperuma at the Ministry by Wijesekara recently.
The invention is a prototype working engine built by using mechanical, electrical and kinetic engineering, and is registered for patent rights.
According to Wijesekara, energy production is a governing factor in development worldwide. The generation of electricity is one of the ways that increase costs of goods and services across the world. Power generation platforms depend on sources, such as petroleum or coal, hydropower, or solar and wind. The increasing global demand for energy has threatened natural resources that should be conserved. Conventional energy production which is associated with the burning of petroleum oils and coal deposits release carbon and toxic gases into the atmosphere.
This is a crucial condition that makes the reduction of ecological footprint even more difficult. The research methodology of the project follows the principles of green energy production, maximum utilisation of convertible resources, minimisation of the energy production cost, and the simplification of the working mechanism.
The free energy generation system uses the gravity and acceleration of road traffic that is converted into electricity by an electricity-generating mechanism through electrical turbines. The system grasps the gravity, weight and speeds of vehicles and transfer that energy to a turbine to make it spin. As the engineering mechanism captures the energy of the moving vehicles into static electricity, the project will not produce any cost for the generation of electricity except for the installation of the system. The prototype electricity generating engine is made and tested with a simplified application methodology that avoids deep excavation on roadways or highways.
Installation
Neither a bridge requirement nor an over-complicated engineering mechanism is involved in the system which has an energy capturing arm laid across the left side of the road with minimum digging and connected to the turbine to produce free energy when vehicles run over the energy capturing arm. The capacity of generated electricity will depend on the number of vehicles that runs over the energy capturing arm.
The size of the turbines and the number of installed system units per every hundred-metre intervals will also decide the capacity of generated electricity. The generated electricity could be transferred to the national grid and, or stored in a storage device to be used as and when necessary.
The system guarantees an environmental-friendly mechanism with zero environmental impact in its operation. Apart from installing the power system in roadways, installing it in railways, bus stations, shopping malls, schools, walkways and jogging tracks are under research. Treadmills and shoe soles are some of the best sources under examination. They have an ability to turn miniature turbines while walking or jogging and convert that energy to charge phone batteries and other portable equipment.
