No matter how far man gets with his fancy gadgets, he still depends on nature for all his energy needs--and that is exactly what designer Anna Gram wishes to convey with her Citrus Clock.

无论在奇特装置的发明上走得多远,人类仍然要依靠大自然来满足一切能量之需--而这正是设计师安娜·格拉姆希望通过她的柠檬时钟所传达的理念。

The clock derives its energy from electrolysis of the citric acid and this helps you leave those toxic batteries away. All you need to do is cut a lemon in half and place each piece on both spikes of copper and zinc and you're good to go. Technically, it's almost the same principle that Mr. Volta used to invent the battery in 1799: electrolysis of zinc and copper (the spikes under the lemon) in a salted or acid liquid (the lemon).

这种时钟可以从柠檬酸的电解过程中获取能量,这样你就不需要用那些有害的电池了。你需要做的只是将一个柠檬切成两半,一半放在铜钉上,另一半放在锌钉上,这样就可以了!从技术层面来讲,其原理与伏特先生1799年发明电池的原理差不多:铜和锌(即柠檬下面的长钉)在盐溶液或酸溶液(如柠檬)中电解。

Ergonomically styled, the simple clock can run for a whole week powered by a single lemon. If you happen some of the stuff in your back garden, then there is no reason why you shouldn't switch over to an eco clock.

这种简易时钟根据人体工效学设计而成,仅靠一个柠檬供电就可走上整整一周。如果你家的后花园里恰巧有些柠檬,那为何还不换用这样的生态时钟呢?
