Benedikt is part of the jury of the open international competition lightshadow. The city is a complex articulated system that needs to be powered by energy. This energy is freely available to us from nature, we just need to know how to use it. (...) One of the great challenges of humanity for the coming years is to make the world a sustainable place, particularly cities, towns and villages, with integrated and environmentally friendly measures, without the capitalist and economic side dominating the process and controlling it. Looking forward for interesting contributions!
