Keepalive is a thermoelectric Wi-Fi router powered up by lighting a campfire underneath the boulder.
The internet runs on Piratebox, a DIY-software that creates offline wireless networks.
As long as the fire produces enough heat the router will stay switched on.
The survival PDFs are loaded onto a USB drive located inside the cavity of the rock.
Some of these strange uploads might have been the work of naughty visitors, but Bartholl doesnt mind.
Its not about easy access, Bartholl said, speaking to Hyperallergic.
