Personally, I wonder if there's anything interesting or interactive on the top. eg: Buttons? display? big red button? wifi password? :> None of the photos or video seems to have looked there yet. ;)
In any case, there is a little monument there with a wifi password and a solar panel. If you sit next to it on a sunny day, there is enough power to run the wifi and a web server which will give you some basic historical and geological info on the place.
