KUCHING: The spiralling cost of cooking fuel is hitting the wallets of consumers in every stratum of society.
But, maybe, not for long, as solar cookers have emerged as a viable way of preparing meals. This fact was underscored by Sarawak Information Systems Sdn Bhd (SAINS) during a demonstration here on Wednesday.
SAINS senior network engineer Allen Liew Than Ho said the benefits of solar cooking were a low investment cost, no running costs, little required maintenance and it was environmentally friendly.
In addition, food being prepared in a solar cooker could be left unattended as it would not burn.
"Solar cookers work by diverting sunlight to a targeted spot, which then traps and generates heat, which cooks food," he explained.
He said on sunny days, solar cookers could cook food almost or just as fast as conventional gas or electric stoves.
For his demonstration, Liew used three types of solar cookers: the bug, the funnel and the shuttle.
All of the solar cookers can be constructed manually with varying degrees of difficulty, with the bug cooker being the simplest to construct and the shuttle the most difficult.
Liew used all three types of solar cookers to cook rice, eggs and sausages within an hour.
Applauding SAINS for its awareness programme, SMK Batu Kawa principal Nedumaran Lingappan said the initiative was helpful in educating students on the importance of conserving energy and the environment.
