Company claims Wi-Fi charging system: RCA Airnergy will suck Wi-Fi signals out of the air and charge an internal battery that then discharges into a handheld. The limits on power for Wi-Fi, coupled with the laws of physics, would seem to argue against this producing enough to be useful. Read the comments on this post where someone works out the charging math. I like the idea, but I can't imagine it becoming a widespread technology, even at about $100 for the battery and charger.

Acela trains gain Internet service in March: Amtrak went full speed ahead on this one. The service will be free at first. Acela is just about the only high-speed rail in the US, operating between Boston and DC, although laughably slow compared to European and Asian offerings.

Private county wireless network in Michigan has government's ear despite lack of funding, uptake: Wireless Washtenaw, a three-plus-year-old network that serves the county in which Ann Arbor is found, has a few hundred paying users, and will likely be out of luck if the county and firm don't get federal stimulus money, AnnArbor.com reports. The county keeps pinning its hopes on this municipally anointed projects, and seemingly brushed off the successful Wireless Ypsi service in Ypsilanti, which offers both free and paid service, and sees over 2,000 users in a week compared to 550 regular Wireless Washtenaw users. Public access county Wi-Fi died out entirely with this exception even before city-wide Wi-Fi mostly went under. (A bonus in this article: my wife's uncle, J. Downs Herold, has an on-the-point quotation.)
