Lots on You tube. I had a browse through the other day after I had commented on it with the specific intention of seeing if there was anything on using an inductive cooker as the energy source as they work at or above the power level desired and have 'done all the hard work' on the transmit side. I found accounts of a number of people doing interesting and/or dangerous and/or arcane things with inductive cookers, some extremely detailed tear downs and circuit analyses, theory behind use as a cooker (slightly more than basic IPT in that mode as skin depth/frequency/material resistivity all join hands and play together when you are *trying* to make heat and carbon steel is better than stainless is better than Alumium* is better than copper at the frequencies they are using so far but ... . And there were people making IGBT kW level drivers based on cookers and otherwise and ... .. Why is it that the days get shorter and shorter and shorter as life progresses? But nobody (that I found) doing good old power transfer using a cooker in an instructable that would have you charging a car battery a day later. There are probably a few there and hiding. Yes I'm sure it's doable. There are many people doing IPT power transfer at all sorts of complexity levels. Later ... .... must not ...
