In this video I will be once again having a look at wireless power transmission. But this time it is all about distance and power because I wanted to find out whether I could achieve the same results as MIT back in 2007. They transmitted 60W of power with an efficiency of 40% over 2m. During my experiment I will tell you lots about good coil designs and power electronics which are required to achieve such results. Let's get started!
