I want to start by quoting:
There was, there is, as we find, only three of the creations as is given, matter force and mind.
It is true, three truly is a Magic Number! A Number given by the Creator!
Force can and does manifest itself in many forms. One we are interested in for our research, is the Inverse Square Law Force. Many other forces including Wind can be exploited.
Inverse Square Law Forces include:
One of my most favourite devices, completely self running, entirely on the Inverse Square Law of Grivation is the Hydraulic Ram Pump. Some 300 odd years old, very well understood. This devices has losses like all Devices do. But the input Energy from the Environment is greater than the Losses and the Energy to run the Device.
It is true, other devices can and do run on the same principles. Using Force to do work. But understanding how these Forces work, and how they can be harnessed is a Experimental Process.
Wind can also be used, Down Wind Faster than Wind:
