a cleanTech design company

  • our energy-efficient hybrid (diesel/electric) engine design
    (fully gasoline or fully electric = low efficiency + high pollution)
  • our Small Wind Turbine (SWT) design
    (huge wind mega-turbines = not green + not sustainable)
  • our pipeline of other designs

GREEN = the highest energy efficiency + the lowest pollution
SUSTAINABLE = you are green + more efficient than last year
