Sarah has reported in the past that Google is testing free wireless access in the San Francisco area called, you guessed it, Google Wi-Fi.
This is old news, I know. But I was surprised to read this morning that a company in Sweden is testing a strategy of providing long-distance, wireless Internet access via balloons.
It sounds like a bad sci-fi plot at first, but then you read that their goal is 120 Mbps over a 60 kilometer range, the future starts sounding better and better. As an added bonus over hardwired connections, no one has to come and tear apart your sidewalk with jackhammers at 5 AM.
