This seems to be more of an art project than a telecommunications aid. Dial the published number, and an answering machine will relay your message to Telemegaphone Dale, which will amplify it and broadcast it over the hills of Norway.
Telemegaphone Dale stands seven metres tall on top of the Bergskletten mountain overlooking the idyllic Dalsfjord in Western Norway.
When you dial the Telemegaphone’s phone number the sound of your voice is projected out across the fjord, the valley and the village of Dale below.
There are no worries about an electrical outage, since the device is powered by wind. Only time will tell if the residents of Dale and the surrounding valley will put up with calls coming in from all time zones. http://www.unsworn.org/telemegaphone/ -Thanks, Sid Morrison!
