In a few years, you may never have to worry about manually charging your cell phone or paying for gasoline again.
几年之后,你或许再也不用为手动给手机充电或付汽油费而费心了。
Wireless electricity isn’t a new concept ? it was publicly demonstrated over 100 years ago by Nikola Tesla - but has remained elusive in mercial applications.
无线输电并不是一个新的概念,早在一百多年前,Nikola Tesla 就曾公开展示过,但此后一直难以实现广阔的商业应用。
However, a pany says they are working to change that, with a business model that could make portable monplace.
然而,一家创业公司正在努力改变这种现状,他们创建的商业模式可使便携式电源成为人们日常生活的一部分。
WiTricity CEO Eric Giler demonstrated pany’s technology during a TED talk, in which he explained, “This all came from a professor waking up at night to the third night in a row that his wife’s cell phone was beeping because it was running out of battery power. And he was thinking, ‘With all of the electricity that’s out there in the walls, why couldn’t some of that e into the phone so I could get some sleep?’”
WiTricity公司首席执行官Eric Giler在一个TED演讲中展示了公司的这项无线输电技术。灵感来源于一位教授的生活经历:他连续三个晚上被妻子手机的振动声吵醒,原因是手机没电而发出了警示音。睡眠备受打扰的他一直在琢磨,“为什么墙里的电不能直接为手机充电呢?如果可以,我不就能睡个安稳觉了吗?”
A team of MIT professors then developed what they call “resonant power transfer,” in which
