Uses solar-powered radios that send text messages in a peer-to-peer network. Each user forwards messages automatically to other users. Uses no internet and no cell phone infrastructure.

Using a simple hill top Bulletin Board System, people can send local text mail to each other, read Bulletins from the Police, Fire and Medical services. You can read news headlines, check the weather forecast and receive urgent announcements sent to your home radio.

Hilltop repeaters can link towns together.

The radios are cheap, small and run off the sun.
