I have gotten a slightly more powerful version (as in the video) but the main problem is that the coil's inductive resistence is high enough that no matter how much current I make avaliable, the current used is still usually below a few amps. The secondary coil is just a few miliamps.
Mr. Duffy, it is up to YOU to discover that breakthrough for fast charging. I hope you do; you could be the person who finally gets all-electric vehicles into the mainstream. Nothing we've seen to date has done a good job of this.
Great job, John. In the next few years, the world's going to need a lot of engineers, like yourself, who are comfortable with LED technology. Very impressive!
Thanks. The wireless charger and coils I used delivered about 12V, so you could charge almost anything. The current, however, is pretty low, so it takes a long time to charge batteries. If you have any improvements to the power output capability or efficency of the design, I'd love to see them.
I agree, DRGONZO. It was certainly exciting to see this young man present his project and to see the next generation of engineers at work. I particular appreciated his desire to be innovative by looking for ways to improve the project.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
