On the LaserMotive blog, I found this reference to a recent article about their own Jordin Kare.
Even though the article is in the online Seattle Times, I think the author of the article is English. From the article; “They require a lot of juice and move around through too many dodgy areas to support a reliable wireless power source.” – no one else uses the term “dodgy” 🙂
Yep that’s a giveaway. 🙂
