A starting choice...

.....if we try to imagine a gravity machine (motor),between the known six types of simple machines:

       -inclined plane family (inclined plane,wedge,screw).

       -lever family (lever,wheel and axle,pulley).

    Now,how about the "family" !?

       All the best! / Alex

I'm sticking with good old fashion mechanical physics,and a combination of swing lift and mechanical advantage .. hell I have been trying for almost a year now, with so many combinations of brain farts the place really smells. but I finally got it, just have to work out a one way mechanical actuator as its the only thing I need the rest works.

Have you ever seen a mechanical pendulum gain swing constantly, hopefully very soon if I can work out a one way actuator on a forward and reverse swing.

pray for me .....
