Research in Motion and Energizer are the latest to sign up to the Wireless Power Consortium and endorsed its Qi standard.
That puts membership of the Consortium up to 21, including Nokia and Duracell. Handset manufacturers tend to be full members; able to influence the standard, while Duracell and Energizer just stumped up €10,000 for access to the draft specification as Associate members.
Just because Nokia and RIM have joined doesn't mean they'll be supplying Pre-like Touchstone chargers any time soon, though. At this point the important thing is to ensure that any forthcoming standard isn't incompatible with existing architectures, to be ready to deploy it if anyone else does.
Wireless power is still a solution looking for a problem, and economic times like these aren't ideally suited for such a pointless technology. But it's worth noting that companies are willing to spend a few quid to make sure they aren't left out if punters suddenly decide they really want wireless power after all. ®
