Letter Re: Off-Grid Electronics

James,

EBook readers and many other small electronic devices can be charged/powered by AA batteries using external power packs like these, available at Amazon and from other Internet sellers.

[JWR Adds: And of course there are a plethora of photovoltaic AA battery chargers available. Well-prepared families should have the ability to charge size AA, CR-123, and 9-volt NiMH batteries without grid power. Those batteries will all prove crucial for operating short-range communications, night vision, smoke detectors, intrusion detection, and other gear.]

Also, the DIYBookscanner web site has some resources for book scanning using inexpensive digital cameras and free software.
