New Tech - Wirelessly Charging Mobile Phones

Wireless power charging is being worked on. Just read on Techtree and Ubergizmo websites that Nokia has joined the consortium that is bringing together work in this direction.

What this promises is that you no longer have to plug the charger wire in the phone.

I was wondering if this means higher power needs, since the charging will be in wireless mode. The following analysis on the Wireless Power Consortium says that the efficiency is comparable. Efficiency of wireless power.

I suspect the handsets with this technology will remain expensive till the time the technology is new and the demand low. Although, in cases of such technology the adoption is pretty quick. Especially if people think that this is really useful.

The good part is that the above consortium is already trying to ensure interoperability.

I had blogged some time ago about standardization of the normal (wired) chargers Good News for Mobile Customers. I think most of us, at least once, have been through the experience of forgetting the charger and then trying to find from people around if their charger can charge our mobile.

Then there are the technology questions -
1. Is this safe?
2. How long will it take to charge a phone?
3. Is this used in some other field / technology?

Another thing to see is the business promise of the technology. I agree that this will be adopted. But the current costs and its comparison to wired chargers will be useful to assess how soon and to what extent.
