太阳的光里有宝 如何提高太阳能效率
|
太阳的光是白光，后来牛顿把它分成了七彩光，现在的太阳能科学又把光能转成电能。整个的思路都是西方科学发展的思路：动能的来源是电能和空气压缩能，汽车，电机，都是这么造的。 太阳光滋养万物，所有的植物与人，都离不开阳光。没有阳光，万物不长。这是所谓的光合作用，但是光合作用的理论只讲了一个过程，没有讲太阳的能量成分。 阳光里的养分、能量，还远远没有被开发。真的是如佛家所说，东西都有了，他就在哪儿，只是我们不知道怎么用。聚光镜是一个例子，但是我们没法儿用它，他把太阳能电池烧焦了。。。 为什么？因为我们还不够好。不是不够聪明，而是不够道德。科学本来是中性的，但是人心的质量赋予科学以褒贬及好坏。停止杀生，停止战争，这是最基本的要求。 |

Store electricity (battery info)
Batteries Stand-alone solar electric systems use lead acid batteries to store power for cloudy weather or for nighttime. Lead acid batteries can be made to withstand deep-cycling, that is discharging them to near-empty. They do not have any *memory* like NiCds do. They can even be re-invigorated if they are abused, for example, sulfation can be reversed, more water can be added, etc. If charged properly, good lead acid batteries will last for years. The larger deep cycle batteries last 10 to 15 years. (source: http://www.etmsolar.com/basics.htm )
