In fact, this rock does not naturally generate wifi but thanks to “human hands”. Turns out, it was the work of Aram Barthonll, a designer who installed a heat-powered wifi transmitter in the rock along with a USB drive.

In addition, in this USB drive one can find PDF files on how to survive with rich content such as: separation instructions, instructions for dealing with remote controlled aircraft, survival instructions for Sassy single woman.

After being heated, the generator will convert heat energy into electricity, supporting wifi broadcasting on Piratebox homemade software, it can create an offline wireless network. Thanks to that, visitors can access, search and download files stored on the USB drive, pre-installed inside this rock.

Aram Bartholl took the idea of ​​designing this rock from an ancient German stove called BioLite that does not have electricity but still works well from the heat source provided by the fire. He is also proud that this is his first work that combines classical and modern elements. This rock is named Keepalive.
