Use pendulum for create energy and move CG without external force

[mcb]

The idea is to use a pendulum:

Pendulum - Wikipedia, the free encyclopedia

For cancel or create weight and for create energy too. This can be used for move the CG without external force.

For example, when we relax at -90° the mass, the centripetal force is T = 3*m*g*cos(x). For obtain the vertical force we multiply by sin(x). The integrate give 9.37 N with a mass of 1kg and a radius of 1m. With g= 9.81 m/sē. Without pendulum the mass to move is 9.81 N.

With this difference we can move up when the pendulum is on and move down when the pendulum is off. Idem for antigravity system.

With R=1m, G=10 m/sē, V0=10m/s, M=1kg:

1/sqrt(100+20*(1-cos(x)))

(100-20*(1-cos(x)))*cos(x)/sqrt(100+20*(1-cos(x)))/0.151149

1/sqrt(100+20*(1+sin(x)))

(100+20*(1+sin(x)))*sin(x)/sqrt(100+20*(1+sin(x)))/0.135939

-(100-20*(1-cos(x)))*cos(x)/sqrt(100+20*(1-cos(x)))/0.151149+(100+20*(1+sin(x)))*sin(x)/sqrt(100+20*(1+sin(x)))/0.135939

The sum give 23.5N on half round
