研究人员建造了无线电动的无人机，可以永远飞行
该无人机是由Sam Aldhaher博士开发的，Sam Aldhaher博士在学术论文中解释了他的作品。In Aldhahers experiment the battery in his small quadcopter drone has been replaced with a coil of copper foil tape which acts as a receiver for the electromagnetic waves that are being put out by the charging plate that the drone is flying over – the concept isn’t all too disimilar to the set up that mobile phone manufacturers and gadget enthusiasts use to power their smart phones, except for the fact that in this set up the drone, as you can从下面的视频中查看，正在飞行。
这是一个很酷的技巧，但并非完全实用，毕竟无线电源只能在很小的距离内可靠地工作 - 但是随着新系统的出现，该范围正在逐渐改善，而新系统可以从15英尺以上无线为设备充电。因此，直到无线电源变得更加好，看起来这个小的飞行演示将仅限于实验室或桌子。有一天，那是监视您的无人机，您无需为其电池充电或睡觉，然后，最后，我们都将在247个监视协会中欢迎您，但是为了抵消至少我们可以将其与247个无人机甜甜圈交付结合在一起。生活还不是不好...
