Sjack Abeling Gravity Wheel and the Worlds first Weight Power Plant

It's not a matter of energy spent. I gave an example somewhere in the earlier pages (don't remember what page it was) with a ball losing the same energy but when constraints are imposed the ball is displaced substantially sideways which doesn't occur without constraints. Modeling the same constraints is crucial.

Displacing a weight horizontally takes very little energy, it is still a loss situation though and does not gain you anything.

Gains you displacement. It's all about displacement under the action of a force. Nothing more than that.

AquariuZ, great video links at the bottom of your posts.

@All,

Here's a model using @broli's method with forced trajectory (see attached). This doesn't work. A counter clockwise tendency at the start is again observed, however. Also, could it be that this forced trajectory is constraining too tightly the spheres, compared to the previous example where spheres had some leeway within the grooves?

If you get a 'zero runner' i.e. something that turns [due torque] then measure its velocity in rpm - see if it accelerates then slows etc - if it holds its rpm or increases then add a torque motor to the sim with a few Newtons of load - if it still accelerates then you have a good chance that you have a winner - OR - you may have to look even more closely at the logic of the build ....
