　　Nowadays, scientists are focusing more and more on green inventions. These are devices that promote the idea of using less fossil fuel1 and being less harmful to the environment. Some of these green inventions will probably become very popular. Some may even fail to get off the ground. Others are just strange. Such is the case with meat-eating furniture. A team of British inventors designed a digital2 wall clock that is powered not by a battery or electrical plug, but by dead flies.

　　The clock has a strip of flypaper3 that revolves. After a fly lands and gets stuck on the paper, it is scraped off by a metal blade4 and drops into a special fuel cell5. There, the fly's body is transformed into energy. Time may have run out for the fly, but not for the person looking at the clock.

　　Of course, living bodies can create electricity as well, thanks to Orange Power Wellies6. These are specially designed rubber boots that will convert the heat from a person's feet into an electrical current7. In turn, the current can be used via a cable at the top of the boot to power a cellphone. It takes 12 hours of walking to charge a phone for one hour of use, but wearers can produce more energy just by making their feet hotter. Just think, you can walk and talk without having to worry about the battery dying on you.

　　現今的科學家都越來越重視各種綠色的發明物。這些發明指的是那些訴求為使用較 少化石燃料和較不傷害環境的設備裝置。這些環保發明有的可能會一炮而紅。有些可能連第一步都跨不出去。還有一些則非常奇特。肉食性的家具就是其中一例。一 個英國的發明團隊設計了一種數位掛鐘，它不靠電池或插頭供電，而是用死蒼蠅。

　　這種掛鐘配有一條會旋轉的捕蠅紙。當蒼蠅停在上頭而被黏在紙上後，牠會被金屬刀片刮下來並掉入特殊的燃料電池中。蒼蠅的屍體會在裡頭轉換成能源。蒼蠅可能時數已盡，但是對看時鐘的人來說可不是如此。

　　當然，活生生的人體也能夠產生電力，而這都要感謝Orange Power Wellies這項發明（編按：這個產品是由英國的Orange公司所發明，故得此名）。這是一款經過特殊設計的橡膠長靴，能夠把人們腳底產生的熱能轉換 成電流。而這股電流就可以透過靴子頂端的一條線路來為手機供電。想讓手機有一小時通話量的電力要走上十二小時才夠，但是穿上這雙靴子的人只要能使雙腳更熱 便可以產生更多能量。想一想，您可以邊走路邊講話，完全不需要擔心手機的電池會沒電。
