A Quasiturbine White Paper by Carol Crom - (published in Energy Central)

A White Paper on the Quasiturbine technology - Quantum Parallel: The Saint-Hilaire "Quasiturbine" As The Basis For A Simultaneous Paradigm Shift in Vehicle Propulsion Systems - Amidst myriad, and many times unsupportable, claims of technological breakthroughs capable -- fuel cells being at the top of this contention --of inducing vehicular design and engineering paradigm shifts, we have concluded that the Saint-Hilaire "Quasiturbine" may very well provide impetus to retire the piston engine. It has served humanity for nearly two centuries, and has earned its rest. eMOTION! REPORTS.com is providing a comprehensive white paper that will perhaps allow you to reach the same conclusion...
