If there's one thing that smartphone users have in common, it's the
perpetual battle with a low battery. There's nothing more frustrating than
having your device die mid-text, mid-song, mid-whatever-it-is-you're-doing,
especially if you're not near an outlet (travelers and outdoorsy types, etc.).
But what if it was possible to juice up your phone, GoPro, or speakers, simply
by holding a ball, and generating clean electricity in the palm of your own
hand?
如果智能手机用户有一个共同之处的话，那就是不断与低电量“交战”。在你发短信、听歌，或是在做任何事中途，设备没电了，没有什么比这更令人沮丧的了，特别是当电源插座还不在你身边的时候(比如旅客、户外活动爱好者等一类人)。但是，如果你只需握住一个球，获取你自己掌心中的清洁电能，就有可能给你的智能手机、相机或扬声器充电，将会怎样呢?

Enter HandEnergy: a Kickstarter-spawned "pocket electricity generator" that
you can take on the go. It looks like a ball, but it houses a magnetic rotor
that produces an electric current that, when you hold the ball and rotate your
wrist to generate motion, charges its own built-in batteries. That current is
transmitted through a USB cord linked to your device -- smartphones, GoPros,
tablets, smart watches, speakers, e-readers, and more -- and charges it.
来认识一下HandEnergy：一款可以随身携带的，由Kickstarter孵化的“口袋发电机”。它看上去就像一个球，不过，它嵌入了一个可以输出电流的磁性旋转体，当你握住这个球，并转动手腕的时候，就可以产生动能，为其内置的电源充电。输出的电流通过一根连接你的设备(智能手机、相机、平板电脑、智能手表、扬声器、电子书阅读器以及其他更多装置)的USB线传输，并为其充电。
The hand motion you have to make to get the energy flowing might make you
look, well, slightly crazy. But aside from your fleeting self-consciousness, the
gadget will make you stay connected to the real world. Science is cool,
right?
你必须活动手部来产生能量流动，咳，这可能会让你看上去有点傻。但是除了你转瞬即逝的难为情，这个小装置可以让你与真实世界保持联系。科学很酷，对吧? |
