看似不起眼的塑膠水桶、故障的印表機，就能夠組裝起簡易發電機，對於能源匱乏的地區來說，是相當有助益的技術！越南河內紅河沿岸，距離河內中心商業區五公里處的水上貧民聚落，就用回收來的紅色塑膠水桶和故障印表機，打造出簡易風力發電機，用於點燈、煮飯，可省下將近1/3的電費。

據《路透社》報導，這種簡易發電機的葉片和馬達都是回收用品組裝而成，供電給舊摩托車的電池，能點亮相當於45瓦燈泡亮度的立燈。

發電量雖小，對於住在離發電廠太遠或是經濟捉襟見肘而不敢用電的家庭來說，卻不無小補，平均一個月可省下9美元（約新台幣290元）的電費。

哈裴範（Bui Van Ha）是一名靠賣陶器養家的當地居民，平均每日收入僅4.5美元（約新台幣145元），他接受路透社訪問時說，「這樣的供電方式已經足以提供我家和附近居民的照明…僅僅是天黑後的幾個小時，就能幫助我們家開源節流。」

這個風力發電機是河內大學講師鍾勒武（Le Vu Cuong）的傑作，善加利用便宜易更換的材料，所需風力只要每秒0.4公尺。

鍾勒武希望增加能源產出，正在尋找潛在捐贈者，幫助改善更多低收入家庭的生活，鍾勒武表示「我們要幫助低收入社區。現在他們有再生能源供應的免費電力可用了。」

Vietnamese families living in slums along the Red River in Hanoi are using red plastic buckets and old printers to help light homes, cook meals and slash electricity costs by as much as a third.

The recycled goods form the blades and motors of electrical generators that power old motorcycle batteries to illuminate lamps with a brightness equivalent to a 45-Watt light bulb.

Though the output generated is small, it makes a significant difference for families previously denied power because they lived too far from a power station or had to ration supply because of the expense, at an average cost of $9 a month.

"It is enough to light the home of my family and other families around here," said Bui Van Ha, who earns about $4.50 a day on average by trading pottery to feed his family of four.

"Even for only a few hours after dark, it helped us to save on our monthly spending and bring profit to my family."

The clean energy innovation on the floating village about 5 km (3 miles) from Hanoi's central business district is the brainchild of Le Vu Cuong, a lecturer at a Hanoi university.

His wind-powered generator makes use of materials that are cheap and easy to replace and works with a wind speed of just 0.4 metres (1.3 ft) a second.

"We want to support the low-income community," Cuong told Reuters. "Now they can use more electricity without any extra costs, with energy coming from renewable sources."

Vietnam produces just 140 MW of solar and wind power each year, but officials say it has the capacity to produce 500 times more.

Cuong hopes to boost energy production, and is looking for donors to help lighten the electricity costs of other low-income families.
