Engineer paper:最强大的能源
Most Powerful Energy Source Nuclear 
 
有三种方法可以使太阳变为能源。 他们是太阳能电池或光伏电池,太阳能热水,太阳能炉。 普通人知道的主要方式,是太阳能电池的太阳能电池板。 “在1839年,法国科学家埃德蒙·贝克勒尔发现了(太阳能) 光电效应。 它被用于1800年代末由组成的“原始太阳能电池 ”。 后来在1950年代,贝尔实验室回做这个技术,使用硅代替了硒,它可以直接将在阳光下百分之四的能量转化为电能(太阳能)。 几年后,这种技术开始被用于推动飞船和卫星。
 
太阳能发电可以进一步分类,而不仅仅是太阳能发电。第一,有直接和间接的太阳能。直接太阳能中将其转化为可用的能源只有一个步骤。而间接太阳能发电需要多步转化为可用的能源。 例如生物燃料,化石燃料,水电站和风力涡轮机,从太阳能引起的风、雨其他气候相互作用,和海洋热能得到能量,从太阳引起的温度差异形成不同深度和波的风上得到能量。也有两个太阳能发电系统的分类。 第一个是被动的太阳能发电系统。 这种系统只需要阳光直射的帮助没有任何其他能源(基础)。 第二个是活跃的太阳能系统。 他们“利用太阳的能源与除此之外其他能源使其工作(基础)。 “太阳能在不同的群体中应用程序也有所不同。第一个是点聚焦抛物面碟”用于把分散阳光转化为集中的太阳辐射(基础)。
 
There are three ways to use solar power for energy. They are solar cells, or photovoltaic cells, solar water heating, and solar furnaces (Darvill-S). The main way that the common person knows of, though, is through solar cells which are in solar panels. "In 1839, French scientist Edmund Becquerel discovered (How Solar)" the photoelectric effect. This was used for "primitive solar cells (How Solar)" in the late 1800s made out of selenium. Later in the 1950s, Bell Labs looked back into this technology, and instead of selenium, used silicon which "could convert four percent of the energy in sunlight directly to electricity (How Solar)." After a few years, this technology started to be used for powering spaceships and satellites (How Solar).
 
Solar power can be further classified than just plain solar power. First, there is direct and indirect solar power. Direct solar power "involves only one step in transforming it to useable energy (All The Basics)." Indirect solar power requires more than one step to transform it into useable energy. Some examples are biofuel, fossil fuels, hydroelectric dams and wind turbines which get their energy from "solar-caused wind, rain other climatic interactions (All The Basics), and ocean thermal energy which gets its energy from "solar-caused differences in temperatures at various depths and wave movement by the wind (All The Basics)." Also, there are two classifications for solar power systems. The first one is a passive solar power system. This "only requires direct sunlight without the aid of any other energy (All The Basics)." The second one is an active solar power system. They "use the aid of energy besides that of the sun to make them work (All The Basics)." Solar power applications also have different groups within them. The first one is point focus which is a parabolic dish "used to focus diffuse sunlight into a concentrated point of solar radiation (All The Basics)." (责任编辑:cinq)
