水瓶灯泡：塑料瓶装水照亮你的家

A Brazilian mechanic has invented a way of lighting his house during the day without relying on electricity.

Alfredo Moser has been using plastic bottles filled up with water and a splash of bleach to illuminate dark rooms since 2002 and now the idea has now spread across the world.

It is predicted that his lighting system, which works using refraction of sunlight, will be fitted in over a million homes by the end of this year.

The secret of the liquid which fills normal plastic drinks bottles that are often thrown away, is two capfuls of bleach added to water, which stops it turning green with algae when exposed to sunlight.

Mr Moser drills a hole in a roof tile and then pushes the filled bottle in from below, keeping the bottle in place with polyester resin, which waterproofs the 'window' in his roof.

He told Outlook on the BBC World Service that depending on the strength of sunlight, the light filling his home is the equivalent of between 40 and 60 watts.

The mechanic came up with the idea for his 'Moser light' during one of the frequent blackouts inBrazilin 2002.

He said only factories had power in his home city of Uberaba, in southernBrazilduring the energy shortage.

It was his boss that suggested using a plastic bottle filled with water as a lens to focus the sun's rays on dry grass to light fires in case of an emergency and Mr Moser developed the concept into his light.

He told BBC World Service: 'It's a divine light. God gave the sun to everyone, and light is for everyone. Whoever wants it saves money. You can't get an electric shock from it, and it doesn't cost a penny.'

Mr Moser earned a few dollars installing the lights in his local super market and neighbours' houses but his invention has not made him a wealthy man.

He said: 'There was one man who installed the lights and within a month he had saved enough to pay for the essential things for his child, who was about to be born. Can you imagine?'

Carmelinda his wife said her husband has always been handy at home and have made tables and chairs.

Illac Angelo Diaz, executive director of the MyShelter Foundation in thePhilippinesalso admires Mr Moser's ingenuity.

The charity uses recycled materials to build houses and has plenty of bottle donations, which it fills with mud to build walls and water to create windows.

It now incorporates water bottles in roofs since learning of the Moser method and also trains local people to do the same in order to earn a small living.

Moser lamps have reportedly been fitted in over 140,000 homes in the Philippineswhere a quarter of the population live in poverty, as well as in 15 other countries, includingArgentina,IndiaandFiji.

Mr Diaz believes over one million people have installed Moser lights in 2013 and credits the mechanic with transforming people's lives.

'Whether or not he gets the Nobel Prize, we want him to know that there are a great number of people who admire what he is doing,' he said.

Mr Moser told the BBC he never imagined his invention would have such an impact but said it gives him goose bumps if he thinks how many people are using Moser lights.

阿尔弗雷多·莫泽说，这种利用太阳折射发光的瓶子灯泡能像40-60瓦的电灯泡一样照亮一个黑暗的房间。

据英国《每日邮报》8月14日报道，一位巴西机修工发明了一种日间不需用电即可为房屋照明的方法。

自2002年以来，阿尔弗雷多•莫泽就利用装有水和少量漂白剂的塑料瓶为黑暗的房间照明，这个想法现在已经传遍全世界。

有人预言，2013年底，莫泽这套利用阳光折射的照明系统将进入1百万户家庭。

他使用的材料是常被人丢弃的塑料饮料瓶，不过里面的液体有一个秘密，除水之外还要加少许漂白剂，它能防止暴露在阳光下的水因生长藻类而变绿。

莫泽在屋顶的瓦片上钻一个孔，把装满水的瓶子自下向上卡在孔里，再用聚酯树脂固定瓶子的位置，这种材料还能为他在屋顶上开的这些“天窗”防雨。他说，依靠日光折射，他家里的照明功率相当于40到60瓦。

巴西经常停电，在2002年一次停电时，这位机修工想出了制造这种“莫泽灯”的主意。他说，他的家乡是巴西南部城市乌贝拉巴(Uberaba)，那里只有工厂才有电。

他的老板曾经在一次紧急情况下建议用塑料瓶装满水，把它们当做聚焦阳光的透镜在干草上点火，莫泽基于这个想法发明了他的水瓶灯。

他对英国广播公司国际频道说：“这是天赐的光明。上帝把太阳赐给每个人，光明是每个人的。谁想要这种光谁就省钱。它不会让你触电，也不用花一分钱。”

莫泽为当地超市和邻居家安装这种灯，从中他只能赚到几块钱，他的发明并没帮他成为富翁。他说：“有人安装这种灯，一个月后，他就为即将出世的孩子攒够了买必须品的钱。你能想象吗？”妻子卡梅琳达说，莫泽在家里很能干，曾自己动手做过桌椅。

亚克•迪亚兹(llac Angelo Diaz)是菲律宾“我的庇护所基金”(MyShelter Foundation)的执行理事，他十分钦佩莫泽巧妙的发明。

这个慈善组织利用可回收材料建造房屋，他们拥有很多捐献的瓶子，他们在瓶子里装满泥沙建造墙壁，装满水建造窗子。

迪亚兹相信，2013年有超过1百万人安装了莫泽灯，他赞扬这位机修工改变了人们的生活。“无论他得不得诺贝尔奖，我们都想让他知道，很多人都很钦佩他的做法，”他说。

莫泽说从没想到他的发明能影响这么多人，但他说，当他想到多少在用莫泽灯的时候确实很激动。
