Solar Power
Which form energy is free during the day,produces no dangerouswaste products and will be ayailable for the next 4 billion years?Solar power,of course.
Here are just some of the things you can do with it,with a bit of simple technology.
Cooking
Get a metal box and put some mirrors and a pot inside.Hey presto,you’ve got an oven!The mirrors focus the sunlight onto the pot to cook the food.The temperature can go to at least 200℃.Somebody first invented a solar oven in Europe a few centures ago.They are very useful these days in places where there is lots of sunlight ,like Africa.The alternative is to cut down more and more trees to make fires.
Heating water
This is the most common use of solar energy at the moment.It works like this.A system of tubes heats up in contact with sunlight,The tubes go into a bank with water in it.A few hours sunshine will give most houses enough hot water for a whole day.Swimming poois can be heated this way,too.
Lighting
Many shops now sell small light which collect the sun’s energy during the day using a small solar panel.At night they can illuminate your garden.The lights on a mobile phone work on a similar principle.Recently,a university student sued this idea in a common women’s accessory- she invented the solar-powered handbag.When you open it,a light comes on.Now it is much easier to look for your door key when you get home at night.
Operating small devices
If you put a mall photovoltaic cell on top of a parking meter,an emergency telephone or a calculator,there is no need to be near an electricity supply.Photovoltaic cells are also used to operate satellites in space.There is a problem they are ecpensive because they are made from silicon.
Keeping things cool
Solar-powered refrigerators are now available on the market.They are useful in places where there is no conventional electricity supply.In the mountains of Kashmir,the survivors of a recent earthquake got safe supplies of blood,vaccines and other drugs because of these refrigerators.

太阳能发电
有一种全天免费,不会产生不安全废物并且在未来的40.000亿年都可用的能量?没错,它就是太阳能发电.
以下只是你可以利用它所做事情的一小部分,只利用了一点小技术.
烹饪
拿一个金属盒,同时在里面放一个锅和一些镜子.变戏法啦,你现在就得到了一个烤箱!这些镜子将阳光聚焦到锅上面来加热食物,而且温度至少可以达到200℃.太阳能烤箱最初是一些人在几个世纪前发明的.近些年,这种烤箱在阳光充足的地区,比如非洲被很好的利用.
采暖水
这是目前最常见的一种太阳能应用.它是像这样工作的：暖气管的一套系统接触阳光来升温,被加热的管道进入储水库.数小时后,阳光就可以为大部分的房间提供一整天的充足热量了.游泳池也可以用这种方法来升温.
采光
很多商店会出售一种通过太阳能面板来全天吸收太阳能的小型灯具.在夜间,它可以为你的花园照明.安装在手机上的这种小灯,也是利用这种原理来工作的.最近,一名大学生将这种想法延续到女性的配件上--她发明了太阳能手提包,当你打开它,里面的灯就会亮起.所以现在,当你夜里到家的时候,从手提包里找出家门钥匙变得轻松许多.
小型设备的运转
如果你把小型的光伏电池放在停车收费表、紧急电话或者计算器上,那就不需要靠其他电力供应设备了.光伏电池也能用来操纵卫星定位.不过这也存在一个问题：它们的费用浩大,因为它们是用硅制作的.
持续制冷
现在,太阳能冰箱很实用于商场.在一些没有常规供电设备的地方,它们非常有用.在克什米尔高原近期的一次地震中,幸存者就是靠这种冰箱来获取安全稳妥的血液供应、疫苗和药品的.
