In 1987, in Madras, India, Friedman completed the Museum of Simple Technology in which the principles of self-construction from local materials such as bamboo were applied. He also authored books dealing with technical subjects (For a scientific architecture, Workshop 1975), sociological (L'architecture du survie, L'éclat 2003) and epistemological (L'univers erratique , PUF 1994). The book that best represents, however, Friedman's ethics and spirit is perhaps "Utopies Réalisables (French for feasible utopias), published in France in 1975 and also published in Italian (Quodlibet 2003) describing a project to restructure our society in a genuine democratic way, seeking to escape any elitism through the theory of the critical group. The book is also a fierce critique of the myth of global communication. From the book: "The analysis of social utopias presented in this book implies, implicitly in the act of accusation and criticism of these two 'plagues' of our times which are: 'the state mafia' and the 'media mafia' (press, television etc.). The existence of a state mafia results from the impossibility of the classic democratic state to keep the shape once its size exceeds certain limits, and the 'media mafia' is a direct result of the same inability in global communication ( Worldwide). The Internet can be used as an example of this inability, which is not the result of technical difficulties but rather stems from the fundamental human inability to communicate universally (from all to all). The failure of these two generous utopias, democracy and the 'global communication' between men, logically leads to the formation of gangs who act on our behalf against our interests. As well as an indictment, this book will simultaneously be an act of encouragement: the individual should be encouraged not to offer their help or their tacit consent to these two gangs. It is not a call for revolution, but a call to resistance. "
