"Be the change that you wish to see in the world." - M. Gandhi. First, the boundless green taiga, lifeless horses on the wild steppes of Mongolia, and an audience with a Japanese princess. And then, the rugged lands of mysterious Ainu, a Jewish "paradise" in Russian territory, and a meeting with an Islamic mystic. Is it even possible during a single expedition? By electric car from Poland to Japan and back. 30,000 km with zero CO2 emissions. Such a journey has never been undertaken before! This expedition wasn't about reaching another challenging destination. The goal was to break away from the usual patterns, to show a different perspective on thinking about the world, ecology, and technology. And it succeeded! Change is possible.Marek Kamiński demonstrated how you can make it happen. In 2020, Marek Kamiński embarked on another ecotechnological expedition, Power4Change, this time around the world. An anthropomorphic robot named Noa assisted the explorer - human and robot joined forces. It was the first expedition of its kind in history, and this book served as its foundation.
