Could it be that water contains an almost inexhaustible source of energy, and above all, that it is within everyone's reach? And what if hydrogen would redefine the contours of our future? Faced with global climate change, the quantities of CO2 from industry and transportation that are released into the atmosphere are widely blamed. In order for humanity and the planet to imagine a viable future by 2100, it is urgent to find a sustainable alternative to our fossil fuels. And in this quest for…

On Pompeii and diverse sites located in Italia, some archaeological discovers will, in their different ways, allow to improve the knowledge concerning the produced and used perfumes during the Antiquity. Jean-Pierre Brun, an archaeologist from the Jean Bérard Centre, and Xavier Fernandez, a chemist from the LCMBA, gather their competences and work together to reconstitute the fragrances of a millenary perfume, the rose from Italia.

To face the last of the fossil fuels stocks, Franck Dumeignil, a chemist, coordinates the Eurobioref project. It gathers research centers and manufacturers from fourteen countries. Its concept is based on the principle of an integrated and flexible biorefinery, which allows to link the preoccupations of agriculture and chemical industry.

Glue doesn ' t only exist in our daily life : it ' s also an unknown scientific problem. The idea of this film is to make people rediscover something as banal as glue, which is the object of important questionings. A researcher in mechanics, a chemist and a physicist explain its mechanisms.

The use of fossil fuels takes part in the increase of greenhouse gases, and influences on the climate. Transports, especially cars, play an important part in this pollution. Thinking about the place of clean energies in tomorrow energetic choices is getting more and more necessary. This film gives an overview of the French research on hydrogen energy, applied to transports. It shows obstacles to the emergence of a mass market for hydrogen cars, solutions that loom in the laboratories and life…

To what extent is photovoltaic energy used in France today? This film looks at various initiatives in progress. Photovoltaic energy from the sun is not just a pipe dream; combining chemistry and physics, it is a field with great potential, which is already being commercially developed. This new energy source is obtained by converting light from the sun into electricity in semi-conductor materials like silicon. The end goal is to produce photovoltaic modules cheaply and increase their…

As chemical and sound pollution increases, the electric vehicle becomes a solution to urban transportation problems. In La Rochelle and Bordeaux, the city government has set an example. The idea comes in various forms - scooters, river boats, and delivery services. Industry and research organizations are actively involved. CNRS laboratories are carrying out research on battery components. The use of electric vehicles of many kinds is becoming widespread.
