And we're doing that by developing an energy storage technology that is long duration and cost competitive.

我们正在通过开发持续时间长且成本具有竞争力的储能技术来达成这一目的。

Building with wood is faster and more efficient than building with concrete and cost competitive too.

用木材建造比用混凝土建造更快、更高效，而且成本也有竞争力。

But the problem is that for electrochemical reactions to become viable, they will need to be more efficient and cost competitive than the heat-powered ones that we use today.

但问题是，为了让电化学反应的方案可行，它们得比我们现在用的热驱动反应更高效还得更便宜。

He knows how to squeeze the last farthing out of a tomato and has turned the sorting of groceries in warehouses into a science—specifically, clever robotics—which has kept costs competitive.

他知道如何从西红柿中榨出最后一分钱，并将仓库中的食品杂货分理工作变成了一门科学——确切地说是聪明的机器人科学——从而保持了成本竞争力。
