Nimuthu Pathiraja reports.
Young masters from grades 6 and 7 at Trinity College have harnessed their inner strengths and creativity to mastermind inspiring contraptions that could make welcoming changes to humankind.
These young inventors, through a tremendous amount of grit and resilience, have made their parents and teachers proud.
Inventor Master Yashwin Fernando.
Considering the adverse effects of plastic and the factors affecting oil distribution, ‘Densor 2’ will minimise pollution and harvest much-needed fossil fuel from our waste.
As plastic is an extract of crude oil, Densor 2 intakes plastic and converts it into gasoline and LP gas. In a process of heating up polythene and plastic, a gaseous component is released. This gas will be cooled and condensed in the radiator to emit from the valves, LP Gas!
Our skilled innovator has wisely recycled an AK12 radiator from a Nissan March, a tin oil barrel and copper and silicone pipes
Water Leak Detector
Inventors: Masters. Ramesh Shanjevigaran, Jed Angelo George, Hareshwar Baleshwar and Firnaz Fiaz
Recognizing water as a scarce and precious resource, and the importance of minimising its waste, our students have collaborated to create a device: a large stainless-steel scale, wired expertly to avoid power shortages, would detect the source of water leaks.
Solid Waste Management System
Inventors: Masters Viduna Rathnasiri, Akain Wijerathne, Prabuditha Wijethunga, Chenul Dias, and Nethmira Godigama
This efficient Solid Waste management system engages in the collection, treatment and disposal of solid waste. This invention will save natural resources, protect biodiversity, and encourage a sustainable lifestyle.
The process starts with an ultrasonic sensor manually detecting IR. A signal is sent to the servo, which opens and closes the mouth of the garbage dumper. Refuse goes in on a slide to the conveyor where the process starts. Large pieces of plastic and polythene will be stuck in a barrier. Smaller portions of food and garden refuse will directly move towards Bin No.1. The pieces which get stuck will move along to the 2nd dustbin.
This magnificent invention has made use of a Servo motor, Ultrasonic Distance sensor, Bearings and shafts, Conveyor Cloth strips, a 12v motor, 4 3.7-volt batteries and other electronic equipment.
Monkey Deterrent Device
Inventor: Master. Gagana Jayasooriya
In recent times, Monkeys, have caused considerable damage to public and private property and agriculture. In a move to protect both the primate and property, a highly effective and efficient device has been invented.
Electricity is provided to positive terminals that are directly connected to a sensor, buzzer, and a motor. The negative current will flow through the terminals of the transistor and connect them to the negative terminals of a sensor. Consequently, a faint sound wave will be released to scare monkeys away, ensuring their safety as well as protection of human livelihood.
This novel creation consists of a motion sensor module, a transistor, a resistor, a buzzer, a motor, a bread board, and other electronic necessities.
Coal Powered Street Model
Inventors: Masters Deenith and Mahadhi
Energy is one of the most important and scarce resources. Therefore, this new process to convert coal to energy could be considered an immense discovery.
After charcoal is heated, the motor is switched on and the lid of a turbine oscillates. Water vapor stimulates the turbine, making it spin. While the turbine spins, the Dynamo will also spin. Electricity is generated to power model streetlights.
This invention was produced with turbines, dynamos, gear motors etc.
Through tremendous astounding planning, dedication and grit, the youngsters have devised timely appliances which deserve praise. On a final say, it is fair to state that these innovations have been made through an unprecedented amount of planning, dedication, grit, resilience, and perseverance. These inventions are much appreciated and encouraged. We must also note down a special word of gratitude goes to the immense guidance shown by the Science teacher Mr. Mohammed Inzimam and the parents of these students. Words of appreciation should be conveyed to the Headmistress of the Middle School Mrs. Krishni George, Mrs. Bhagya Dissanayake and Mrs. Fathima Majeed must also be acknowledged for their unstinted guidance. We wish all the students in their future endeavours to make the world a better place.
