How does Google Gears geolocation work?

I'm quite impressed by the Google Gears geolocation demo. It usually has an accuracy under 50 meters and besides authorizing Google Gears, I haven't revealed any other information concerning my location. What technologies are used to achieve such accuracy?

When the StreetView car passed by in my neighborhood, it logged all the access points and their nearest location using the car's GPS. Using the API, it correlates my location with the APs I can see with my Wi-Fi adapter.
