This Christmas Tree Is Powered by Brussels Sprouts
WOW! It’s really awesome!
多棒的點子啊! 本周稍早，在倫敦《青年科學家與機械工程博覽會》上, 首展是用1000顆甘藍菜球心發電，點亮了8英尺高的耶誕樹. 這不但激發了年輕孩子的靈感, 同時也提供了他們未來對科學展業的追求. （更深入介紹： http://www.thebigbangfair.co.uk/View/?con_id=3041 ）
Finally, a way to put the Brussels sprouts you didn’t eat at dinner to good use.
In an effort to inspire youngsters to eat their vegetables and pursue science careers, The Big Bang UK Young Scientists & Engineers Fair debuted an eight-foot Christmas tree with lights powered by a battery made out of 1,000 Brussels sprouts in London earlier this week.
Here’s how it works, according to the fair’s website:
Copper and Zinc electrodes are placed in each Brussels sprout to create a chemical reaction between the electrodes, generating a current which can be stored and used to power the LEDs on the tree.
The power is stored in a capacitor and released through 100 high efficiency LEDs.
If you want to try this at home, but don’t have that many leftover Brussels sprouts, here’s how…
