For this 21 th edition, the EVS was curiously held in Monaco: A place where it is fashionable to appear with heavy cars, imposing and as recent as possible but displaying around 400g CO2 / km with other pollutants in proportion !!
What a fine example selfishness, rudeness and extreme arrogance as written rightly Nicolas Hulot in his excellent book 'Titanic Syndrome'.
In short, different technical solutions seem to compete with each other as they simultaneously arrive at the 'artificial' micro-market for sustainable mobility. The best solution seems to be the fuel cell that performs reverse electrolysis. Hybrids are only an intermediate solution ... but immediately comparable to our current cars, while all the victims of pollution have "forgotten" the freewheel if used on the pre-war cars!
This obvious and simple solution makes it possible to ride free on the inertia or the momentum of our heavy current cars ... Waiting until the received ideas change, because the free wheel is not dangerous in turn, on the contrary, rolls disengaged or at dead point as soon as possible!
Personally, simply by disengaging, I measured significant gains in city and on the road! In short! But what is the proposition of an engineer INSA Mechanical Engineering before the manufacturers and other official organizations or why make simple when it can be complicated?
