Abstract
All these projects will address energy savings to improve the use of energy from currently available sources without substituting other sources of energy. In the very near future, the public authorities in France will help to promote non-petrol vehicular systems, electric domestic vehicles, alcohol petrol mixtures, and wood gazogenous engines. These non-petrol systems cannot be developed for or at this symposium. This technology will be developed in the next few years, and we shall have a better knowledge of it in the near future. (A)
