Gravity motor concept design

Good one michel. That design looks promising. bouyancy differences are likely to give better results than moment based systems.

two things though. first friction at the piston/container contact area could really mess up that system. If friction is kept at a minimum here and watertight conditions still exist then it may work.

second, i'm not real sure how much of a volume change one can produce when the suction and compressive reactions of the gas in the system are considered.

he did state that nitrogen would be used in the chambers but if my experiences with empty (needleless) syringes are anything to go by, those pistons won't get very far before suction or compressive pressure in the chamber stops them.

Are there independent replications or commercial versions of the unit?

@guruji:  spring based systems that involve changes in spring lengths (to me) are mostly a bad idea. you consume energy compressing/stretching those springs and that in itself is enough to defeat the goal of such designs.

At the same time, a magnet (single free magnetic pole) tends to attract at points beyond the expected line of action i.e they tend to pull elements closer together when such elements should be moving apart.

Usually you have only small moment differences to play with in overbalanced systems and these design approaches eat up whatever advantage one seems to have created.
