Bogs are also flooded with sunshine, so even an inefficient carnivorous plant can photosynthesise enough light to survive.
沼泽也充满阳光,所以即使是低效的食肉植物也能获得足够的光,依靠光合作用生存。
To demonstrate their approach, they added the genes to a bacterium and found that a flask of the bacterial culture produced enough light to read a book by.
为了展示他们的方法,他们给一种细菌添加了这种基因,并发现培养细菌的烧瓶中放出的光足可以在旁边看书。
Generating enough light could be prohibitively expensive, unless cheap, renewable energy is available, and this appears to be rather a future aspiration than a likelihood for the near future.
除非有廉价可再生能源,否则制造足够光的成本可能会高得令人望而却步,而这似乎只是未来的愿望而非近期能实现的。
He learned to get light to go far enough down a glass fiber to pass on signals.

Well, we can't guarantee with UV light we'll have enough energy to eject every single electron, so that's why when we use x-rays, they're higher energy, you can pretty much be guaranteed we're going to eject all of those electrons there.
好,我们不能保证紫外光有足够的能量,激发出每一个电子,所以我们要使用,X,射线,它的能量更高,你可以非常确定,我们可以激发出其中所有的电子。
They were not hot enough -- like stars-- to give off light.
