It’s about being up in the clouds free to do anything you like. Riding a bike on a rope ladder or doing other nice things that come to your mind. The feeling of a colorful life and the freedom to travel wherever you want in the sky. In my childhood I lived up in the north of Sweden where there were often northern lights sparkling in the black sky. This is what it looked like in my childish eyes. Sometimes you could even hear it sound a bit.
When I lived in northern Sweden some time ago, I now realize how many memories you have. I lived a period up in Skellefteå and still have a lot of relatives there. Now when they are building one of the bigger battery factories in that town, I thought it was appropriate to send some electric clouds up there. They might need some electric fuel? :-)
