Since it has been brought into u, its creators say more than 1000 people have drunk others’ “sweat” in Gothenburg. They add the liquid is cleaner than local tap water.
The device was built for the United Nations’ child-focud charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.
The machine was designed and built by the engineer Andreas Hammar, known locally for his appearances on TV tech show “Mekatronik”. He said the key part of the sweat machine
was a new water purification part developed by a company named HVR.

They have something similar to the International Space Station, but our machine is cheaper to build. The amount of water it produces depends on how sweaty the person is, but one person’s T-shirt typically produces 10ml, about a mouthful.”
The device has been put on show at the Gothia Cup-the world’s largest international youth football tournament. Mattias Ronge, chief executive of Stockholm-bad advertising agency Deportivo, said the machine had helped rai awareness for UNICEF, but in reality had its limitations.
“People haven’t produced as much sweat as we hoped – right now the weather in Gothenburg is lousy,” Mattias Ronge said. “So we’ve equipped the machine with exerci bikes and volunteers are cycling like crazy. Even so, the demand for sweat is greater tha
n the supply. And the machine will never be produced in large numbers, since there are better solutions out there such as water purifying pills.”

2.Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers, small, tightly knit(联系) groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12,000 languages between them.
Soon afterwards, many of tho people started ttling down to become farmers, and thei我长大了的作文
r languages too became more ttled and fewer in number. In recent centuries, trade, industrialisation, the development of the nation-state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caud many languages to disappear, and dominant交春 languages such as English, Spanish and Chine are increasingly taking over.
At prent, the world has about 6,800 languages. The distribution of the languages is hugely uneven. The general rule is that mild zones have relatively few languages, often spoken by many people, while hot, wet zones have lots, often spoken by small numbers. Europe has only around 200 languages; the Americas about1,000; Africa 2 400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800. The median number(中位数) of speakers is a mere 6,000, which means that half the world's languages are spoken by fewer people than that.

Already well over 400 of the total of, 6,800 languages are clo to extinction(消亡), with only a few elderly speakers left. Pick, at random, Busuu in Cameroon (eight remaining sp
eakers), Chiapaneco in Mexico (150), Lipan Apache in the United States (two or three) or Wadjigu in Australia (one, with a question-mark): none of the ems to have much chance of survival.
