Dr Singhal has implanted prototype devices into live beetles.

Singhal博士将设备原型移植进了甲虫活体。

That could render Dr Singhal's device inoperable after only a few months.

这会使得Singhal博士的设备在移植后的几个月内便无法使用。

Mr Singhal has bigger aspirations yet; for a while he thought he might aim to become prime minister.

但辛格哈尔的野心远非于此；曾经他还想过，将来可能会把目标设为登上印度总理宝座。

The downside is that platinum is a less efficient catalyst than the enzymes used by Dr Singhal, and so Dr Sarpeshkar's cell works less well.

该方法的缺点是铂催化剂与Singhal博士所用的酶相比效率不高，因此，Sarpeshkar博士的能量池运转效果不好。

That could render Dr Singhal's device inoperable after only a few months. Equally worrying are the enzymes, which tend to break down over time. Losing enzymes means losing power.

这会使得Singhal博士的设备在移植后的几个月内便无法使用。同样使人担忧的是酶，这种物质随着时间的推移会被分解。而丢失酶就意味着丢失能量。

One approach, which has been employed by Sameer Singhal, a researcher at the CFD Research Corporation in Alabama, involves the same enzymes that break down glucose within a living cell.

就职于Alabama的CFD Research Corporation的研究人员Sameer Singhal所使用的方法涉及利用酶将活细胞中的葡萄糖分解。

That is only around a fifth of the power that a pacemaker requires, but Dr Singhal reckons that a human-sized version of his cell would be able to deliver enough juice.

这只是一个起搏器所需能量的15分之一，但是Singhal博士认为人类体积大小的细胞量能够产生足够的能量。

Dr Singhal has implanted prototype devices into live beetles. Fitted with a fuel cell about the size of a penny, the bionic bugs were able to generate over 20 microwatts (20 millionths of a watt) during a two-week trial.

Singhal博士将设备原型移植进了甲虫活体。放入了一个一便士大小的能量池，这些甲虫在2周实验期内产生了20微瓦（一瓦特的百万分之二十）。
