Imagine that society has fallen, and you are out in the wild, desperate to survive. Sure, maybe you still have your smartphone, and even a solar/crank/backup charger. But what you need right now is information on how to survive, and with society down for the count there is no infrastructure providing you with the data you seek. So what do you do?
Well, thanks to the creative mind of artist Aram Bartholl (english translation), you might be able to build a fire and tap into a boulder for the information. Bartholl has built a heat-powered WiFi data server into a real, 1.5 ton boulder, appropriately named, “Keepalive”. All you need to power things up can be found lying about on the ground – just build a fire against the boulder and connect.
After connecting, you will find a wide selection of survival (and curious) PDFS for your perusal. While you are at it, you could even upload any collected PDFs you may have collected or created (notes, maps) for the next person.
Right now it is an art project, but it does put forth an interesting project idea. Maybe the next time you are out in the wild, you can pull up a boulder and tap in to some information. Or at least you could find a comfortable spot in the sun – boulders are always handy for that, even the non-digital ones.
