Hidro SouthEast Queensland Gravity Generators 50MW for 3.75M$AU

http://peswiki.com/index.php/Directory:_Hidro_--_Water_Pressures_Energy_Conversion_(WAPEC)

Hidro looks to be a method of extraction of energy from gravity using the change in pressure of water.
I Look forward to hearing of developments in extracting energy from gravity. Gravity has a much better capacity to supply safely and long term as force is proportional to inverse distance squared. Current methods of linear (VP/T) ambient temperature heat exchange ie modern combustion can not sustain the allowable limits of vehicles and industry. Gravity has a much larger availability for extraction from the environment than temperature heat exchanged to the atmosphere and is safer environmentally.
I am curious to see if Hidro becomes open source at some stage. I gather that the "energy must be free" hypothesis must be true for humanity to become sustainable.

Multi Dipole Magnetic Simulation

Introduction

Multi Dipole Simulation of two bar magnets one attached to a wheel the other to a fixed point external to the wheel. Each magnet consists of 5 dipoles at 1cm distance apart for a total of 5cm length per magnet. The magnets are at 0 degrees and 180 degrees respectively.
The strength of the magnets are 0.01 Amperes per meter squared(A/m^2).

Multi Dipole simulation omega=180 degrees phi=0
Disk Mass 1.2kg 25cm in diameter
Bar Magnets Length 5cm
Dipole Length 1cm
Added Friction from normal of force
