‘MY HELPAIM IS TO PEOPLE’

ASASTUDENTOF RICHMONDCOLLEGE, GALLE, AND HAVING OBTAINED EXCELLENT RESULTS AT HIS ORDINARY LEVEL EXAMINATION, ALWIS WASSELECTEDFORA PROGRAMMECALLED SCIENCEFORYOUTH IN 1987.
Here, he was introduced to the world of science and invention by worldrenowned scientist Dr. Arthur C. Clarke. Amongst them was someone who grabbed young Alwis’ attention. It was none other than the legendary visionary and the Father of Innovation and Invention Dr. Ray Wijewardene.
Philip Revatha (Ray) Wijewardene, educated at two of the most prestigious universities in the world, Cambridge and Harvard, excelled in many different areas of science, including agriculture, aviation, engineering design, invention and renewable energy technologies to name a few.
With a deep interest for all things mechanical, Dr. Ray studied and experimented, especially with agricultural machinery and airplanes.
These twin passions took him a long way. He was fond of saying, “Agriculture is my bread and butter, while aviation is the jam on top of it”.
He is credited with inventing the world’s first two-wheeled hand tractor the Land Master to help small farmers as well.
He dedicated his life to researching and promoting ecologically sustainable agriculture, and later, renewable energy technologies. As a seasoned pilot and an aviator, he built several ultra-light aircraft and helicopters, and trained a generation of pilots and aircraft technicians.
In order to honour one of the greatest catalysts and inventors Sri Lanka had ever seen, the Ray Wijewardene Charitable Trust (RWCT) was established in early 2011 to promote Dr. Ray Wijewardene’s vision and ideas in Sri Lanka and to help upcoming creators.
Inspired to invent
Taking a walk down memory lane,Alwis recalled his first interaction with his hero.
“Meeting Dr. Ray Wijewardene during that time seems like a dream now. He not only lectured us but he also showed us several of his inventions such as the Land Master,” he said.
“One of the things that truly fascinated me was the aircraft he had built. He took us to the Ratmalana airport and demonstrated how they worked. I was amazed to see his motorcycle-engine-powered airplane and somewhat nervous too as I could not imagine how such an aircraft could fly so high. It was the first time I had seen something like that. He became my hero and role model as he showed me a destiny in the aviation field which I had not seen before,” he reminisced.
As fate would have it, today he is one of the finalists for the Ray Award 2015, an accolade set up to honour Alwis’ hero and to recognise outstanding inventions. His creation – the Cold Air Retainer Door Screen System for Refrigerators and Bottle Coolers – was selected to be among the four best innovations of the country.
“It is truly an honour to be nominated for this award because it is an award given in Dr. Ray Wijewardene’s name. I owe it to him for showing me this path,” he said emotionally.
Alwis is convinced that it was that first encounter with Dr. Ray Wijewardene which inspired him to join the Air Force and also ignited his passion for science, technology and innovation.
“My dream was to become an engineer but I could not get into the university. Soon after school I joined theAir Force. By that time I excelled in electronics and motor mechanism and had a basic knowledge and hands-on experience in the field,” he said.
Not long after,Alwis became a qualified
Mr. Alwis’s visit to Ratmalana Airport with Dr. Ray Wijeywardene on 07 Nov1987 Flight Engineer in MI-17 helicopters. He flew planes in some of the most war-torn areas at the time such as Jaffna, Elephant Pass and Mullaithivu.
Even during his time at theAir Force, he found new creative ways to solve problems that they came across. One time, he managed to repair both engines, electrical systems and to replace main rotor blades of a MI-17 helicopter at the Vettrilaikerny beach during an air operation.
It was a task that was deemed impossible without a crane and required ground support facilities, but Wing Commander Alwis found a way to get the helicopter back on its rotors by innovatively utilising available army personnel to a build an access ramp with sand bags which facilitated them to access rotor blade replacement.
He then got the opportunity to be appointed as the Officer in Charge Research and Development, Officer in Charge of hardware of the Information Technology Unit, Officer Commanding Maintenance of the No 111 Searcher MK-II UAV Squadron, Quality Assurance Inspector of Fixed and Rotor Wing aircraft, Staff Officer to the DirectorAeronautical Engineering, Directing Staff at The Defence Services Command and Staff College and presently as Officer Commanding Aircraft Repair and Salvage Section of theAircraft Engineering Wing of the SLAF Base, Katunayake.
After the war, he completed his Bachelor’s Degree in Defence Studies in Management at the Sir John Kotelawala Defence University and the Staff Course at the Defence Services Command and Staff College Sapugaskanda, where he completed his Masters in Defence Studies conferred by the University of Kelaniya.
An energy-saving creation
It was his research for his Bachelors and Master’s Programmes, based on energy saving, which led to his innovation.
Alwis explained that the Refrigerator Cool Door Retainer was a simple and user-friendly solution to stop energy wastage from having the refrigerator door open for a long period of time.
“I had noticed that in most households, people kept the door of the fridge open for a considerable period of time. Sometimes they are thinking about what they need; sometimes they open the door several times while cooking. My own kids used to keep the door of the fridge open for a long time. This means that the cool air is leaving the refrigerator and the inside of the fridge is warming up. This wastes 40 percent more energy,” he explained.
He explained that the refrigerator amounts to more than half of our energy usage. In order to reduce the energy wastage from having the door open, he invented thick plastic screens that could cover the shelves of the fridge so that the inside of the fridge was not exposed to the atmosphere even when the door was open.
“This saves at least 7 – 10 units of electricity. That is a 15 percent saving of energy. When I first tried this at home in 2009, my electricity bill was reduced by 8 kWh per month. Now I have developed it so more money and energy can be saved,” Alwis said.
“It is safe and clean because the food in the fridge is not affected by the outside temperature for several minutes. This helps to maintain the optimum level of safe temperature of the fridge for a longer periods of time so that the food is kept cool and fresh even when the door is open,” he added.
Alwis’ simple, practical and costeffective invention got him his first patent – a dream come true – as well as a Presidential Award.
However, Alwis has not taken his invention to the mass market yet. He cited the lack of time as the main reason for this.
“I am an inventor; I am a person who makes ideas into something useful. The main aim of my invention is to help people, with a cost effective solution, for a significant problem,” he said.
