首先，它们利用太阳。
它们利用太阳光获取能量(反射的阳光施加小量压力与太阳帆上，进而驱动其前进)，因而无需燃料。
They draw their energy from sunlight (the reflected light exerts a small pressure on the sail, driving it forward) and therefore need no fuel.
根本用不着画笔，我只利用太阳和地平线，它们自身就能创作图案。
Instead of a brush stroke, I'm using the sun itself, the horizon itself, arranged to create images.
也可以用镜子集中太阳光线，利用它们烧开水，利用蒸汽驱动发电机。
Or you can concentrate the sun’s rays using mirrors, boil water with them, and employ the steam to drive a generator.
至于动力，它们会利用太阳能或是温度变化从环境中“捡”一点能量。
For power, they "scavenge" energy from the environment, using solar energy or temperature changes.
利用几组太阳帆并非实现太空旅行最快捷的方式，但是它们的造价低廉。
Solar sails are not the quickest way to travel through space, but they are cheap.
一项最新的模拟实验表明，围绕太阳系的尘埃盘中存在一个空洞，利用这个空洞可以向外星观察者发出信号，告诉它们这里有行星存在。
A hole in the dust disk surrounding our solar system would tell alien observers there are planets here, a new simulation shows.

当天空很晴朗的时候，太阳和星星可以指明方向。如果在它们下面有个人在密林里迷路了，总在原地绕圈那个迷路者更应该利用它们来找到方向了。
When the sky is clear, the sun and the stars help to guide the course, and if they are followed one is saved from traveling in a circle, as the lost are pretty sure to do in a dense forest.
它们通过利用暴露在空气中（利用太阳能）或者使用地热，从而防止水结冰。
These can still prevent water from freezing by limiting its exposure to the air, or by using the heat from the ground.
但是它们并没有利用所有的太阳热能，因此在能量到达电池前浪费了大部分的太阳能。
But they don't take advantage of all that solar heat, thereby missing out on the majority of the solar energy reaching the cell.
相反的，太阳神代表的是一种能够处理高涨活力的力量，利用有破坏性的力量并把它们转换为有创造力的行动。
The Apollonian, by contrast, represents the power to deal with the powerful surge of vital energy, to harness destructive powers, and to transmute these into creative act.
各种环保元素在改造伊始便被融入进来，它们包括：利用太阳能采暖系统满足房屋电力需求；
Environmental features were incorporated from the start. They include: a solar-powered radiant heat system to provide for the house's electrical needs;
