The solar energy is dependent on sun, the wind on nature’s change of weather, the hydroelectric on water, geothermal on volcanic steam and sea wave on nature as well. This new technology does not depend on any of the aforementioned sources, but on the inherent property of gravity which is unchangeable at all times: hence the operation of this technology is by far incomparable to these renewable energy prime movers due to the constraints on their sources.

Since fossil-fuel and nuclear-based prime movers are ruled out because they are not environment friendly and very expensive to build initially and in the long term, the comparative analyses are focused on the renewable energy machines versus Cangrier-M Perpetual Motion Machines.
