Hongkongers used to live comfortably without air cons

Electric fans started to replace punkahs in Hong Kong as early as the late 1890s. When my Chinese friend arrived in 1917, so he told me, punkahs could still be seen in offices, schools, barbers' shops and in Saint John's Cathedral.

It's cool to save energy

Energy costs are constantly rising, so installing a ceiling fan is not only practical but also cost effective. They also look graceful.

During summer, a room can feel up to five degrees cooler thanks to a wind-chill effect. In winter, the fan can be set in reverse to recirculate escaping heat from the ceiling to the floor.

Fans are a cool solution

As summer heats up the city, there is another way of cooling your home without the resulting exorbitant power bills and environmental damage caused by air conditioning. Fans are becoming increasingly popular, not only for their sustainable cooling abilities but their decorative possibilities.

Talent shows are not a waste of time

I am writing in response to the star letter 'Say 'no' to teenage talent shows' by Sonam Chophel Wangchuk (Young Post, February 15). I don't agree with him.

It is true people value knowledge. Our economy is knowledge-based. But stars who don't have do well at school can still can have a bright future.

We can ill afford further delay on idling engines

Amid the heat generated by professional drivers criticising the proposed ban on idling engines, Secretary for the Environment Bureau Edward Yau Tang-wah should keep his cool.

Engine-off rule will take toll on men and cars, drivers say

Taxi drivers say the planned rule on idling engines will increase wear and tear on their cars and themselves.

Turning the engines on and off more frequently will cause them to break down more often, while drivers will be put under stress by worrying about when they have to switch off and by sitting in hot cabs with no air conditioning, they say.

Researchers behind a government-funded study into a power system for cars that provides temporary air conditioning when the engine is off have highlighted the difficulties they ran into.

Nevertheless, taxpayers will see another HK$3 million of their money spent on a separate look at the idea. And this time the technology being investigated is different.
