Student inventors of the DPS International School, an Indian private school in Tema, have appealed to the Government to adopt their scientific innovations and turn them into workable ventures.
Using materials such as plastic bottles, straws, paper, leaves, solar panels, and cables, the students came out with different scientific concepts to achieve their objectives.
The students made the appeal in an interview with the Ghana News Agency on the side-lines of a science fair organised by the school on the theme: “Sustainable Solutions for A Sustainable Future”.
Master Shrirang Chandankhede, a science student, said with the over 30,000 vehicles plying the Tema–Accra motorway daily, the air they produced could be captured to generate an estimated two kilowatts of electricity to add to the national grid.
He said the government could put together a group of engineers and architects to plan the installation of turbines that would turn the mechanical energy produced from the wind emanating from the passing vehicles into electrical energy.
He said the model would be cost-effective and done on all major roads, adding that the energy produced could also be used to power an electric vehicle charging system along the roads.
He said with the introduction of electric cars, environmental pollution through vehicle emissions and the health risks would also be minimised.
Master Kwame Gyamfi Boateng, and Miss Anukriti Srivastav, year nine science students who exhibited a solar irrigation system, said with the abundance of sunshine in Ghana, solar could be used for a better and more effective way to irrigate large farms.
The reservoir would also have an indicator to cut off the supply when full as well as a sound-sensitive sensor to turn off the controller to avoid spillage and wastage of water.
They called on the government to put in the needed investment to maximise the gains from farming by prioritising such inventions geared towards making farming easy.
The students said there was enough water underground that needed to be harnessed for agriculture purposes.
