All improvement ideas converged when they suggested making a turbo-shaft turbine having only one turbine in one plane... In order to achieve that, the inventors had to attach the turbine blades one to another in a chain like configuration, where the rotor acts as compressor for a quarter of a turn, and as engine the next quarter of a turn... This is the Quasiturbine! Many researches are going on to increase energy efficiency on the long term with piston, hydrogen, fuel cell... Hybrid concepts are ways to harvest part of the low power efficiency penalty of the piston engine used in vehicle, but counter-productive measures limit the long term perspective until they could efficiently fuel from the electrical grid. None of these solutions are short term stable and competitive. The Quasiturbine in Beau de Rocha (Otto) cycle is a relatively simple technology which could be widely used within a few years with substantial efficiency benefits over piston engines in many applications. Large utility plants convert energy more efficiently than small distributed units and should be favored when possible, but on the long term, the Quasiturbine detonation engine (AC model with carriages) is one of the very few means to match utility efficiency the distributed way, while being as chemically clean as possible. By opposition to dozens of new engine designs, the most important at this time about the Quasiturbine is the fact that it does unknot a new field of development and offers means to achieve what no ot
