未来城市垂直农场

简介:

  到2050年,全球将有七成的人居住在都市,城市必须供养70亿人口。如果用传统的土壤耕作,还需要增加一整个巴西的耕作面积,才有可能养得活这么多的人,但是高楼林立的城市里,哪里生得出这么多土地呢?如果城市能够盖出摩天大楼,有可能盖起摩天农场吗?为了解决城市粮食供应的问题,垂直农场应运而生。
  城市垂直农场把水平的农场,改造成种满植物的摩天大楼,用营养液代替土壤,用LED灯取代阳光,这些彷佛科幻小说的情节,在各领域专家的努力下,正一步步成真。垂直农法在密闭的空间种植农作物,压缩了空间,让效益极大化,除了节约土地,也节约用水量,用水仅是传统土壤种植的十分之一。可以楼上种菜,楼下卖菜的垂直农场,也大大缩短了食物里程,减少食物长途运送的资源浪费。
  垂直农场发想者的本意,是解决全人类的问题,然而这种耕作方法现阶段仍有个无法克服的致命瓶颈,就是生产成本太高,目前只能为少数阶级服务,奢侈品是无法养活全世界的。全球人口最多的城市,有四分之三分布在亚洲,这些亚洲的大都市,无不全力支持垂直农场的发展,因为比起其它地方,他们分秒必争。

简介:

  For the first time in HELL'S KITCHEN history, the latest batch of 20 aspiring restaurateurs head to Las Vegas to present their signature dishes before Chef Ramsey and a live audience. The contestants will split into two teams - the red team and the blue team - to prove they have what it takes to win a life-changing grand prize as Head Chef at Gordon Ramsay Pub and Grill at Caesars Palace. The winning team with the most impressive dishes will earn a VIP night on the town and attend a special concert, while the losing team will make the long journey back to Los Angeles on a school bus
  For fans that can't wait to get their fix of the celebrity chef Gordon Ramsay's toxic-tongued kitchen antics, the wait is almost over.
  Tuesday kicks off the newest season of "Hell's Kitchen" with a two-hour episode on FOX.
  In the premiere, three contestants --Amanda Giblin, Dan Ryan and Jessica Lewis --are among the 20 chefs that compete in front of a live Las Vegas audience for a cooking challenge that pits the men against the women. They talked to FoxNews.com’s Ashley Dvorkin about what it’s like to be on the show and what’s in store during this—the 11th season.
  Giblin says one of the biggest challenges for her was cooking in front of the large, live audience, for which they were given no advanced warning. “It was incredible, scary,” she said.
  In Tuesday’s show they say there’s an extra contestant that is neither man nor woman. Also the winning team (they don’t say who) gets a VIP night on the town, while the losers get a bumpy ride home on a hot school bus.
