Ask HN: When will we say “We used to have to charge phones with a wire??”

Hopefully between now and then (or whenever it happens) we find a way to wirelessly charge things that does not waste 90% of the transmitted power. Maybe some variant of this: http://en.wikipedia.org/wiki/Magne_Charge. Even a 10% loss is bad, though, and a total waste of power. Every watt counts.

I'm hoping that battery capacity improves enough by then that charging will be an afterthought, something we just do on weekends etc. So there wouldn't be such a focus on the charging mechanism (because using it would be such a rare event).
