  • Floatable micro-hydropower Station with helicoidal rotor 
    BOSTAN, I.; DULGHERU, V.; CARTOFEANU, V.; CIUPERCĂ, R.; CIOBANU (Romanian Inventors Forum, 2010)
    Floatable Micro-hydropower station helicoidal rotor provides kinetic energy conversion of river water into electrical energy. Increased efficiency is provided by helicoidal blades with aerodynamic profile in normal section.
  • Planetary Precessional multiplicator 
    BOSTAN, I.; DULGHERU, V.; CIOBANU, R.; CIOBANU, O.; CIUPERCĂ, R. (Romanian Inventors Forum, 2010)
    The various energy conversion systems require multiplicators with high performances. The high multiplicity of the precessional gearing assures high bearing and small dimensions. This factor has allowed the elaboration of ...
  • Wind Unit with Vertical Combined Rotor 
    BOSTAN, I.; VIŞA, I.; DULGHERU, V.; CIUPERCĂ, R.; CRUDU, R.; GUŢU, M. (Romanian Inventors Forum, 2010)
    Small wind speeds which are characteristic for the Republic of Moldova do not allow efficient utilization of the classical wind working elements. To increase the conversion efficiency of wind energy at speeds a new wind ...
