[00:00.20]Rural communities in developing countries [00:03.12]often have trouble securing dependable supplies of energy [00:07.24]for cooking and lighting. [00:09.92]But energy exists every where organic waste is breaking down. [00:15.28]It is just a question of how to harness or make use of it. [00:20.40]A Palestinian community in the West Bank [00:23.44]has been successfully testing a device [00:26.12]that turns food and animal wastes into biogas. [00:31.32]The village of al-Awja has no running water or electric power. [00:36.92]Solar panels provide energy from the sun, [00:40.36]but not enough for cooking equipment. [00:43.20]But as in many other parts of the world, [00:45.88]villagers keep chickens, cows or other animals. [00:51.12]Recently, about 40 families started using portable devices [00:56.38]that turn food and animal waste into methane gas. [01:01.48]The European Union and the Peres Center for Peace [01:05.35]provided money to pay for the devices. [01:09.00]One villager says, "This is a very good machine... [01:12.80]The machine provides us with 70 to 80 percent [01:16.20]of the gas that we need for our household." [01:19.80]An Israeli company, HomeBioGas, [01:23.08]designed the machine, called a bio-digester. [01:27.24]Anaerobic bacteria are added to the device [01:30.40]the first time it is used. [01:32.92]The bacteria helps break down organic waste. [01:37.04]The bio-digester creates enough methane for cooking three meals a day. [01:42.44]It also produces about 10 liters of liquid organic fertilizer. [01:47.96]Biogas is smokeless and has no smell. [01:52.32]In addition to cooking, biogas can be used to heat water [01:56.52]and for lighting devices. [01:59.08]A built-in, hand-powered grinder [02:01.60]helps break down the solid parts in household waste. [02:06.12]The HomeBioGas system [02:08.04]is designed for areas where the daily temperature [02:11.36]does not drop below 15 degrees Celsius. [02:15.64]The price is about $2,500, [02:19.60]a somewhat pricey amount for most families. [02:23.56]So, communities must depend on aid from governments or private donors.

Rural communities in developing countries often have trouble securing dependable supplies of energy for cooking and lighting. But energy exists every where organic waste is breaking down. It is just a question of how to harness or make use of it.

在發(fā)展中國家，農(nóng)村社區(qū)通常很難獲得可靠供應(yīng)的能源供做飯與照明使用。有機(jī)廢物分解的地方就會產(chǎn)生能源。這只是一個如何利用它的問題。

A Palestinian community in the West Bank has been successfully testing a device that turns food and animal wastes into biogas. The village of al-Awja has no running water or electric power. Solar panels provide energy from the sun, but not enough for cooking equipment. But as in many other parts of the world, villagers keep chickens, cows or other animals.

位于約旦河西岸的巴勒斯坦社區(qū)，已經(jīng)成功地測試一項設(shè)備，該設(shè)備可以將食物與動物糞便轉(zhuǎn)化為沼氣。奧賈村不通水電。太陽能電池板提供太陽能，但這對于烹飪設(shè)備而言遠(yuǎn)遠(yuǎn)不夠。但與世界上其他地區(qū)一樣，村民們飼養(yǎng)雞、奶牛及其他動物。

Portable Device Turns Organic Waste into Biogas

Recently, about 40 families started usingportable devices that turn food and animal waste into methane gas. The European Union and the Peres Center for Peace provided money to pay for the devices.

最近，約有40多個家庭開始使用該便攜式設(shè)備，將食物與動物糞便轉(zhuǎn)化為沼氣。歐盟及佩雷斯和平中心提供資金來購買該設(shè)備。

One villager says, "This is a very good machine... The machine provides us with 70 to 80 percent of the gas that we need for our household."

一位村民表示，“這臺機(jī)器很不錯！它為我們提供了70%到80%的天然氣，供家庭所需。

An Israeli company, HomeBioGas, designed the machine, called a bio-digester. Anaerobic bacteria are added to the device the first time it is used. The bacteria helps break down organic waste. The bio-digester creates enough methane for cooking three meals a day. It also produces about 10 liters of liquid organic fertilizer. Visit the website www.chinavoa.com to get more information!

一家以色列公司，HomeBioGas，設(shè)計了該機(jī)器，名為生物沼氣池。第一次使用該設(shè)備時，添加了厭氧菌。厭氧菌有助于分解有機(jī)廢物。生物沼氣池能夠產(chǎn)生足夠的甲烷供一日三餐使用。它還能生產(chǎn)約10升的液體有機(jī)肥料。

Biogas is smokeless and has no smell. In addition to cooking, biogas can be used to heat water and for lighting devices. A built-in, hand-powered grinder helps break down the solid parts in household waste.

沼氣無煙，也沒有氣味。除烹飪之外，沼氣還可用于燒水及照明設(shè)備。內(nèi)置的手動砂輪機(jī)有助于分解堅硬的生活垃圾。

The HomeBioGas system is designed for areas where the daily temperature does not drop below 15 degrees Celsius. The price is about $2,500, a somewhat pricey amount for most families. So, communities must depend on aid from governments or private donors.

HomeBioGas系統(tǒng)適用于那些日常溫度不低于15攝氏度的地區(qū)。價格約為2500美元。對大多數(shù)家庭而言，有點昂貴。因此，社區(qū)必須依靠來自政府或私人捐助者的援助。

But the designers note the system can also be useful in more wealthy communities that have organic waste which can be turned into clean energy.

但設(shè)計師指出，該系統(tǒng)對于一些比較富裕的社區(qū)同樣有幫助，那些社區(qū)里的有機(jī)廢物可轉(zhuǎn)化為清潔能源。
