Any place you see a differential, there're some interesting questions. There's some questions as to what you should be doing with this stuff. But again, coal. Maybe the same stuff, maybe the same system, maybe bioenergy, and you're applying exactly the same technology.
每个地方都有些不同之处，有些问题 很有意思。有的问题诸如 你应该如何对待这些东西。但是 仍以煤炭为例，它们可能是同样的东西，可能 是生成与同样的体系，可能就是生物能源，你都在运用 相同的技术。
