Welcome to Gravitational systems engineering.   We design and manufacture gravity powered systems for commercial and industrial applications.   Since 1998 we have been developing  gravity powered pumps, compressors and generators..

Our pumps and compressors operate with no conventional fuels, such as electricity, gas, or petro-chemicals!  Gravity is the power source for all our devices.   Our R-series, or relative gravity energy, systems harvest  energy that is normally wasted as heat,  friction or wear.  We manufacturer  R-series systems for pedestrians, livestock, motor traffic, trains, aircraft transitions, and ships.  Many of our R series products are designed to be employed in safety and motion control applications.

Our S-series, or static gravity energy, systems also harvest power earth's gravitational field.  Static gravity is harvested from water weight, and natural displacements.  S-series systems include both high energy deep ocean systems, and surface hydro systems.   

Thank you for your interest in our products.
