English Version . Sometimes it happens to be convinced that some processes, some products or some services are the result of recent discoveries, that some strands of thought such as recycling, green economy, circular economy, renewable energy or the function of plastics, among supporters and against, have been born in recent years.

Everything seems so close in time, the seas polluted by plastic, the garbage on the streets, the separate collection that does not work as it should, global warming, vehicular traffic and the fossil combustion boilers that pollute the air, the hope of hydrogen, wind and sun for cleaner energy and to fight against rising temperatures on the planet.

The media, social networks, people talk about climate change, the rationalization of the use of products, the reuse and refusal of disposables, sustainable mobility, a less unbalanced diet towards meat, forestation for carbon balance, of desertification and upheavals of natural habitats with the consequence of the birth of new unknown viral strains that threaten man.

A bombardment of news, concentrated, which seem to have been born all together, developing as an intertwining of interconnected links that strengthen our sense of restlessness. ;

Between hopes and anxieties we try to understand the evolution of the intertwining between environment-consumption-production-energy-waste-food, as if no one before today had realized how much the correct management of these phases are indispensable for our future and that of our children.

But nothing seems safe as in this period, nothing seems to have an evolution from the past that makes us understand how to face the future based on the experiences of those who preceded us, everything seems new and unknown. ;

But it is perhaps the load of news that pervades our daily life in which we sometimes do not have the time to investigate and weigh things, which makes us think that there is no past and everything happens today. ;

In reality there are many things in our life that although they seem recent or relatively new or even only sketchy and of which we await the arrival as the resolution to current problems, in reality, in most of the times they are known to historical paths.

Maybe they were sketched, used then abandoned and then resumed, they were immature and today they can return vigorously thanks to technological advances, out of time then and now current, not essential in the past but useful today. ;

We are talking about scientific discoveries, indispensable materials, innovative industrial processes, initiatives to protect the environment, sustainable economy and attention to the environment, in a historical period in which none of this was really considered important, but that marked a beginning, through far-sighted and out-of-the-ordinary men who stubbornly sowed a small seed that, after years or centuries, made a continuity with modern times flourish.

In this book we start from afar, from the medieval period, to link our present with our past and, through characters who worked in completely different sectors, we go up the slope of the years, up to the present day, with what still seems to we the future: hydrogen.

It is not a history book, but an episodic story, liberations drawn from the life and work of famous or completely unknown people, told on the basis of the contribution they have made to progress, small or large, but always innovative and still useful today for our life.

Many other characters can follow, all united by the certainty that today we are where man wanted to be, for better or for worse, and that nothing is born by chance, suddenly. ;
