 >>  Hanoians beat the heat in West Lake

Low-income households in Hanoi have been sharing tips to create an air-conditioner which costs only some VND200,000 (USD9.5) to cope with the extreme summer heat.

Nguyen Van Dung learned how-do-do tricks on online forums and social networks before sharing his advice on Facebook. During Hanoi's most recent heatwave, with temperatures exceeding 40 Celsius, the need for an affordable air-conditioner became very apparent, especially for low-income families.

Interest was great because there are still many in the country who do not have the luxury of a conventional air conditioner. Dung claimed that it was possible to make an extremely cheap air condition that worked. The machine has now become a trend in the city.

This homemade appliance consists of a box, a small fan, an L-shape tube and glue. Those who make it simply cut two holes in a box, install the tube and attach a fan. While working, the box contains ice blocks. As the invention spread around the internet many people opted to use it instead of a conventional air conditioner, not only because of the low cost of the materials used, but also because of the savings in electricity.

One commenter said that the cost of VND200,000 to buy the necessary materials was much better than spending VND7-10 million to an air-conditioner. The cost of ice is varies, but the apparatus is still more cost-effective. He said, "With VND5,000 worth of ice blocks, my 'air-conditioner' can run for three hours, even when the ice has melted, the air stays cool for a while."
