I see a lot of you saying things like, "big deal," "this idea sucks," "just use batteries," etc. As though the current implementation is the final version of this technology. I'm surprised that, on /. of all places, you guys aren't thrilled that this implies in the near future you won't even notice this technology... it ought to just work.
Instead you're all bashing it and claiming it's a bad/stupid idea and implying they ought to just scrap the whole project.
I say - keep working on it, no matter how ugly those coils are, because I know sooner or later, I won't even see the coils anymore.
