Because of this whole Easter thing, news is kind of slow today. So, yes, we are going to talk about a charger and a rumoured release date for the Palm Pre. The Palm Touchstone is a charger that uses magnets to keep the phone in place, while charging it through induction; there's no plugs or anything. Palm has let out more details on this new type of charger, and there have also been a number of hints that the Pre might be released on Queen's Day (April 30 for all of our non-Dutch readers).

It is efficient enough...though not as efficient as plugging it into a socket. With the right contact surfaces (and geometries) and some clever signal processing you can get it so losses are negligible. Systems such as these are already used in industry when there are hazardous environments where having an electrical connection would be too dangerous (in underwater situations unfeasible).

How efficient is induction? It would be a shame if millions of phones started using this simply because it was "cool". Longer charge times, more fossil fuels burnt. Sounds like a big negative to me.
