菠菜营养丰富,人所共知;但是说菠菜可用来做电池,为手机和掌上电脑提供绿色环保能源,听起来好像有些荒诞,但确也是不折不扣的事实。
Spinach is known for its rich nutrition. But it may sound absurd to say that spinach can be used as a battery and as a green energy source for mobile phones and hand-held computers, but it's also true.


Recently, us scientists have successfully developed the "spinach battery", which may be the real green battery in our mobile phones in the near future.


The study was conducted by scientists from the Massachusetts institute of technology, the university of Tennessee and the U.S. naval research laboratory. It is well known that green plants can convert solar light energy into physical energy through photosynthesis. "All green plants, large and small, can convert photons into electrons through photosynthesis, which converts sunlight into electricity." "Explains Shuguang Zhang, who led the study. In experiments studying plant photosynthesis, scientists have found that a protein complex in plants called Photosystem I converts solar energy into electricity. Although the amount of electrical energy converted by the protein complex is very small, it gives us an excellent indication. "We will be guided by the transformation of light energy and electricity into the natural world," he said.


Given that spinach has high levels of chlorophyll, is cheap and is available throughout the year, scientists have targeted it for the final study. Scientists have created a special kind of tiny spinach cell that contains a lot of spinach's photosynthetic system I protein complex and conductive material. One problem is that all proteins need water when they work, and water is the enemy of cell phones and computers. In this case, the scientists from revelation, wrapped in seed appearance of reservoir to spinach battery "wear" a is not only can protect protein in water environment to live, and can help cell phones and computers waterproof "appearance".
