  中廣網北京3月30日消息 據中國之聲《新聞縱橫》報道,美國麻省理工學院的科學家在3月27日表示,他們已經研制出第一片實用性人造樹葉。這種人造樹葉其實是一種高級太陽能電池,隻有扑克大小,模擬植物光合作用的原理可以產生電流。

  這種人造樹葉是以真正的樹葉為原形研制的,但是它跟自然界的橡樹、楓樹和其他綠色植物的葉子不同,這種樹葉的外形很像扑克,它是由硅、電子和催化劑構成,把葉子放在一加侖水裡,然后放在陽光下,它就能夠把水分分解成氫和氧產生電流,一片葉子產生的電能可以滿足發展中國家一個家庭一天的用電需求。

  科學家也表示,這種人造樹葉能幫助發展中國家的貧困家庭用上便宜、清潔的電能,讓每一個家庭都有自己的發電站。

需要多些空氣嗎?人造樹轉換二氧化碳成氧氣
Need More Air? Artificial Trees to Convert CO2 to O2
Mar 16, 2011 – 5:49 PM

It's not nice to fool Mother Nature. Or is it? If you're not getting enough air, you might want to spend time sitting under a newly designed artificial tree that converts carbon dioxide into breathable oxygen.

In the modern world of urban pollution, we can't seem to grow enough trees to naturally convert carbon dioxide into life-sustaining air -- the process of photosynthesis -- until now.

Researchers at New York's Columbia University, working with Influx Studio in Paris, have designed a faux or artificial tree. It's basically a machine fashioned to resemble a dragon blood tree, complete with wide branches and umbrellalike tops that are used as support for the large solar panels that will power the tree, according to PhysOrg.com.

This idea of faux trees has taken root in Massachusetts with an urban tree competition called Boston Treepods 2011. Sponsored by the SHIFTboston organization, teams of designers have developed proposals for synthetic urban trees that would essentially do what real trees do -- convert carbon dioxide into oxygen -- but without the need to be planted in soil or nourished by water.

"Influx Studio in Paris is currently pulling together the specifications and obtaining necesssary approval on specific patenting, and it should be finished by the end of April," Kim Poliquin, director of SHIFTboston, told AOL News in an e-mail.

"Following finalization of documents and approval in early May, SHIFTboston will put the Boston Treepod out to bid. We are hoping to obtain competitive pricing to produce the initial prototype," she added.

Composed of recycled plastic bottles, the treepods utilize a carbon dioxide-removal technique called "humidity swing" that helps clean the air.

These air-filtering faux trees look like giant futuristic urban lamps that light up at night in multiple colors. They can also generate energy via solar panels as well as kinetic energy created by young and old sitting on interactive seesaws attached to the base of the trees.

Purists might object to the idea of creating artificial trees, saying that all we need to do is plant more trees. At least these treepods would be up and running, so to speak, long before new trees can provide the same amount of oxygen to a geographic location.

SHIFTboston is aiming to "plant" the prototype treepod by early 2012.

Would Mother Nature object?
