The exhibition is on display at Heureka for the time being.
Electri City is a city of smart electricity
Could you produce the amount of energy contained in your cell phone battery yourself? Could you survive a three-day power outage?
At the Electri City exhibition, you can find out what a smart home is like and how you can use electricity yourself smartly. In addition, we will find out how the electricity travels from the power plant to the home.
In the city of smart electricity, you can also experience how much energy can be stored in the battery of a current smartphone - and how quickly an electric stove would consume it.
In addition, in the exhibition's escape room, you can test whether you could survive a three-day power outage.
A multi-annual cooperation project
The Electri City exhibition is part of a multi-year cooperation project between STEK and Heureka. Other partners in the exhibition are The Finnish National Rescue Association SPEK and Brammer Oy.
