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.
