The goal, as its name implies, is to harness the power of the largest laser ever built to start "ignition" - effectively a carefully controlled thermonuclear explosion.

顾名思义，国家点火装置的目标是借助世界上迄今为止最大的激光器进行“点火”——有效且可控的热核爆炸。

The $3.5bn National Ignition Facility (NIF) sits in a 10-storey building covering three football fields and will harness the power of lasers to turn tiny pellets of hydrogen into thermonuclear energy.

美国国家点火装置（简称NIF）耗资35亿美元，建在一个十层楼高的建筑里，占地面积有三个足球场那么大。 它将利用激光把氢同位素靶丸转化为热核能量。

Instead of sparking the ignition when the piston is close to top dead center (when the air is compressed), that spark occurs as the piston is pulling away, when the air pressure is at its most turbulent, creating much faster ignition and more power.

In severe cold, below -15C, before you turn the ignition key flash your main beams - this takes a bit of battery power and thaws it a bit inside.
