Outernet is an interesting service that broadcasts a large amount of internet-mined content via an orbiting satellite. Anyone can receive it, providing they have the appropriate equipment, on a Raspberry Pi. Here’s some info on the information that is being broadcast from the Raspberry Pi Foundation:

The content is the kind of thing you would find in a public library, with resources on human health, anatomy, encyclopaedias, how-to guides and news feeds. The data is broadcast cyclically so that any new receiver joining the broadcast can catch up with everyone else. The content received from the satellites is cached and served out to the users via http pages, meaning that any device with a browser can be used to read it (both Ethernet and WiFi are supported). It’s worth noting this is only one-way content, because you can’t send messages back up to the satellites.

So it’s kind of a satellite-powered internet for places where you can’t receive the internet. The Foundation have purchased a kit from the Outernet website and set it up on their roof. Read more here.
