Bloom Energy are producing tiny fuel cell boxes they call "Bloom boxes." Two of these can apparently power a U.S. home (and only one for homes in countries that use less power).

Bloom Energy制造的这种小型的燃料电池盒名叫“Bloom Box”，只需两块即可为一个美国家庭供电(乡村地区用电较少的家庭，则仅需一块)。

One of the great challenges they'll face and that your generation will face is the fuel cycle itself in producing nuclear energy.

他们以及你们这一代人将会面临的巨大挑战之一是在生产核能的过程中燃料自身的循环。
