The mystery of the stone itself emits Wifi when heated

This hot stone is able to generate a powerful Wifi source for everyone around the internet connection.

The rock is located at the entrance of an outdoor sculpture museum in Neuenkirchen, Germany. At first glance, the rough, rough stone has nothing special, but this 1.5 ton stone block is a work of art called "Keepalive" by German artist Aram Bartholl.

The rock weighs up to 1.5 tons.

The most interesting thing is that whenever the stone is heated, it will emit Wifi waves so that it can access the internet.

Of course it will not suddenly be so miraculous but because the inside of the rock is installed with a Wi-Fi transmitter powered by heat and a USB drive.

When heated, the generator will convert heat directly into electricity. The Smart Phone and Laptop in close range can access Internet via Wi-Fi by Keepalive.

Sharing with the press, Aram Bartholl said his work is a combination of ancient and modern survival elements.

Burning the rock is easy and you can catch Wifi and go online.

According to Aram Barthonll, Keepalive's idea was derived from this artist from a type of kitchen called BioLite - a type of stove without electricity but still works "well" thanks to the heat from the fire. Since then, this German artist has embarked on researching and producing Keepalive rock that surprised and shocked many people.
