More on finding the lost
Submitted by brad on Thu, 2006-12-21 13:59Last week, I wrote about new ideas for finding the lost. One I've done some follow-up on is the cell phone approach. While it's not hard to design a good emergency rescue radio if you are going to explicitly carry a rescue device when you get lost, the key to cell phones is that people are already carrying them without thinking about it -- even when going places with no cell reception since they want the phone with them when they return to reception.
