But instead of coating the carbon cylinders with fuel, a liquid fuel could be stored in the car's gas tank and get injected onto the carbon nanotube battery when needed.
Instead of a battery lasting two days, the same battery providing power to sensor systems built with carbon nanotube transistors may last up to two weeks, "said Przybysz."
代之以持续两天的电池，同样的电池为用碳纳米管晶体管制造的传感器系统提供的能量可以持续两周的时间。

As Ms Granholm admits, whether the battery cluster turns out to be a good deal for taxpayers may depend on America adopting tough policies towards carbon emissions.
