Pendulum hydro pump concept: it's open source - build it!
My friend David Matos de Matos who is of Portuguese descent living in Angola, has described a possible way to reverse entropy using hydraulics (see Thermoenergetics: Can Hydraulics Reverse Entropy? on this blog). David has now come up with a simple idea of making use of gravity and a pendulum, together with hydraulics, to produce a useful pumping function.
David's pendulum hydro pump concept is simple and can be built by everyone. It is based on the idea of Milkovich, who says that a suitably heavy pendulum can produce more power than is necessary to expend in order to keep it swinging. The basic idea is described in PESWiki:
Here is what David says about his invention:
"I [have] just come up with the pendulum hydro pump.
Similar to Milkovic´s device it may be an over unity machine.
I tried with a rudimentary setup in springs, with a rigid rod firmly tied to the bearing. The swing of the pendulum was steady. Looked like the force on the springs where the same on both legs. I did not find any vibrations on the pendulum and the amplitude behaved like the schematic showed on the website.
The pendulum keeps swinging, with the pivot making a parabola. It looks like, if we extend an imaginary line from the rod up, it will have an imaginary fixed pivot.
I am setting up everything for a prototype. Let´s see how it goes.
I am inviting everybody to build small prototypes because we will have different perspectives and improve it.
I am not filing a patent, and wish that a lot of water pumps being installed in Africa, the most needed good in this continent.

You can find more information and can get in contact with David by going to his blog, which he specifically made to get out the word on this idea.
If you are mechanically inclined, please try this one out and let me (and David) know what you are finding.
Perhaps this can be a real open source effort to usefully employ in places that are in need of water pumps but don't have electricity...
Here is a call, received more recently, for experimenters to duplicate what David has been working out in his head and put on this video:
DOUBLE PENDULUM HAMMER 2
"I tried to make a prototype but I don´t have the material and tooling conditions. I could´t get a proper ratchet. It is the main component to create a centripetal force that will originate the centrifugal force.
I believe that it will accelerate due to increase in angular velocity of the hammer.
I am inviting over unity enthusiasts to build a prototype.
If works it will be a good business to manufacture and sell miniature toys of the first over unity device.
