工程和化學的蠻力向生物學轉變時。

you do that stuff, here's what happens to

你的生產力是在這裡得到增長的。

productivity.

當你從事這種生產時，生產力的變化

Basically, you go from 250 hours to produce 100

是這樣的。

bushels, to 40, to 15, to five. Agricultural labor

基本上是這樣的，從1950 年到2000年，你生產100 蒲式耳的糧食的時間

從250小時降到40小時， 再到15小時， 再到5小時。

2.5倍。這絕對是

The effect of this, of course, is it's not just

人均產量的巨大增長。

One of the ironies of this whole system is we're

discussing what to do about a system that we don't

這整個體系的自相矛盾之處是

不瞭解的體系。我們甚至都不知道石油是什麽。

literally, it's still a source of debate what

我們也不知道石油是從哪裡來的。我的意思是，

你得到的就是這些黑色的河流。

that thesis turns out to be true -- is that oil,

現在，關於這些理論的有趣的事是

吸收光能，將其集中在變形蟲身上，

集中在植物上，可能那就是

And as you're looking at this system, if

你得到這些彩虹的原因。

hydrocarbons are concentrated sunlight, then

當你觀察這個系統的時候，

bioenergy works in a different way. And we've got

如果烴是聚集的陽光，那麽

to start thinking of oil and other hydrocarbons as

生物能源是以不同的方式產生的。我們已經

This is how you farm oil. And as you think of

和這些灌溉田地沒有相似之處的

farming oil and how oil has evolved, we started

這就是你怎樣在油田採油。當你想到

with this brute force approach. And then what did

採油和石油是怎樣演變的，我們開始

we learn? Then we learned we had to go bigger. And

這種採用蠻力的方法。那麽我們學到了

then what'd we learn? Then we have to go even

什麽？那麽我們學到了我們不得不擴大規模。

然後我們學到什麽？然後我們不得不再

we're going out and farming this bioenergy.

擴大規模。這樣我們在走出去開採生物能源時，

這個。但是，再一次強調：我們不知道。

這一事實是我們在辯論所有這些時應該感到奇怪的。

但當你想到煤時,這是燒焦的麥核的樣子，

看上去不是完全不像煤。
