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.

Thank you.  I have many more projects and I plan to submit some of them this summer.

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.

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!

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.

It would be nice to say "we saw him here first!"

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.
