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.
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.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
